Thanks very much Chris. Pleasure to be here and to be part of your series on. The impact of C O two on global climate change. I understand from some of the previous seminars speakers that many of the questions that rose after the climatologist spoke about what the magnitude of global climate change is after they spoke there are many questions about well what do we do about it and you know what. What is the best response to this climate change threat and so I'm here to speak more to the technologies available to try to reduce greenhouse gas emissions then to the science of global climate change because I am not a climatologist but I have been surrounded by climatologists for decades. So I've absorbed quite a lot and I wanted to also know that the title of my talk is transitioning to a climate Smart Energy Economy technologies barriers and effective policies I think that maybe the advertisement said technologies basics or something like that in case you were beef old what that meant. Typically the way that I've been approaching an assessment of technology opportunities for mitigating climate change is to look at the characteristics of the technologies look at the marketplace look at the barriers that are preventing widespread deployment of those technologies and then address the policy fixes that might be able to tackle those barriers so that's kind of the transition in the back of the technologies the barriers and and then try to identify smart policies. So my one and only sort of climate slaw it. Starts by saying well we've got a problem. It is now in dispute in this beautiful or unequivocal that. The glow. Of a climate is warming. This is some of the terminology from the I.P.C.C. two thousand and seven report which I was a co-author on the mitigation report and they concluded that most of the observed increasing globally average temperatures system mid twentieth century is very likely due to the observed increase in anthropogenic greenhouse gas emissions or concentrations and that very likely in quotes is a very precise. Term it means ninety percent probability and believe me that probabilistic assessment took years to arrive at and ratcheted up over each of the three year intervals when the I.P.C.C. report reports were published. So increasing certainty of the impact of bridge and a greenhouse gases and course. Greenhouse gas emissions are intimately linked to the combustion of fossil fuels and then another set of quotes is that. One of our goals is to avoid dangerous interference with the climate system that comes out of the UN Framework Convention on Climate Change that was signed by the United States in one thousand nine hundred two. By George Bush which says we are going to try to avoid dangerous anthropogenic interference with the climate system. We saw in that at the time we had no idea where we were relative to being in a position of jeopardizing the climate. And it turns out here we are and many think we are here indeed already. And in order to avoid further interest in her Ference we are going to have to reduce greenhouse gases. Significantly and over a long period of time and I would like to say and early action is critical sort of being hotly debated as to how much time we have I believe. Early Action is critical because every moment that we delay opportunities are lost and new infrastructure is put in place. It has a long life. A new power plant fifty years so you're stuck with it. Want to spilt if it's billed as a polarized coal plant. You know you've made that commitment and it's hard to reverse it. So I'd like to start by showing where the United States stands in terms of the productivity with which we use energy to drive our economy and I know we have a delegation from France here. So I was pleased to see that my chart does have France on it as well and I gave this talk actually to a group from Sweden last week in Savannah Georgia and we kind of make a little cluster there the French this the U.S. we're all fairly inefficient in terms of powering our economy relative to say the Japanese comparable. Style of living standard of living but the Japanese use half the energy per G.D.P. relative to the United States or Sweden or France. We have improved so you can see in one nine hundred eighty six the blue numbers tend to be larger than the gold numbers two thousand and four numbers. So we are using less energy for our domestic product but it's still relatively high and Georgia. In fact within the United States is more energy efficient than the average state. So to me. This is actually a cause for optimism. Because we have a lot that we can do to improve the energy efficiency of our economy because other countries have already done it. And if you look at our carbon footprint per capita C O two emissions. You can see that the United States and along the top with twenty metric tons per person over time what these thoughts are are yours as our G.D.P. has grown in general our carbon emissions have also grown and in fact that pattern of economic growth and. Carbon intensity carbon footprints is a pattern for which there are very few exceptions there are a couple of exceptions and in fact the French have offered an exception with their significant use of nuclear power and the English have the carbonized by moving off coal and a highly efficient building stock. So there have been instances where countries have been able to grow their economy and shrink their carbon footprint but in general. These two go in lockstep. And so the real question is can we break the link between economic growth and growth in carbon. Consumption. So again grounds for optimism we have a terribly inefficient energy system really worldwide lots of opportunity for improvement carbon emissions are only just beginning to take on a price or a value. So we have. Still the promise of the market place responding to carbon prices once they are set and made more significant. And also if you're looking to a significant decline in the missions by two thousand and fifty. You can think about the fact that well. Majority of the energy infrastructure that will be in place and twenty fifty has yet to be built. So we have a lot of control over our mid century fate. The theme of my talk then really is what we can do in terms of using energy more wisely I'm going to touch on other technology responses as well but in my opinion energy efficiency is a low hanging fruit. It's the one response that we can take that actually will pay us. To do a better job. Whenever you adopt a cost effective energy efficient technology. You are saving money. There's a lot of money to be saved. This is a chart by the National Resources Defense Council which builds on a fairly famous curves that they make Kinsey. Company published in December of two thousand and seven their chart. It's a supply curve carbon mitigation options and I didn't put it on here because it has about seventy five technologies in the tiny print in this hard to see and that's what Resources Defense Council has been generalizing from that analysis and presents here I think a clearer vision of what the generic kind of lessons are from the McKinsey study. So you order the technology options from left to right according to their cost everything that has a bar. That's below the line. Has a negative cost. That is offers a savings. And you get to the. Two The zero point zero carbon fuels these are a breakeven technology and then everything to the right. Cost you something like renewables concrete or alternatives other greenhouse gases high. Global warming industrial gases for instance would fit into that category carbon capture and storage cost you something other innovations so going from left to right. You see a line up of a total of about eleven billion. Tons of C O two that can be saved. Here at a. At a cost of forty at a savings of forty dollars per dollar ton of C O two abated. And that category is energy efficiency in buildings. And then you move to energy efficient transportation and industry. So the three sectors of the economy for which energy can be used more wisely and then you go to those options that cost you something now what's interesting is if you were to integrate across the left or right you would get a total that's just positive by a little bit in other words we can get all the way to that ten or eleven gigatons of C O two reduction and hardly see any impact on the. On the U.S. G.D.P. because what is on the left just about equals the benefits just about equal the costs on the right. So all of this is a very nice strategy to cut us. Greenhouse. Yes the missions. So when you think about energy efficiency. You need to first consider how energy is used in the economy. So in the United States. The bulk of the energy. Actually this is placed in terms of million tons of carbon. So the both of the energy generated tons of carbon come from a heating cooling in lighting buildings. And the next largest segment is transportation at thirty two percent and then industry at only twenty five percent and shrinking. Every time I update the chart. You add something to buildings and use attracted from industry and transportation is that about the same. And that's partly because we're offshoring so much of our energy intensive industry it's not because we're doing such a magnificent. Of producing. More sustainable products. And you can then further dig deep into characterizing the nature of the energy that's used in each. Sector and you can get a nice simplistic diagram is worse formulating strategies around. What is that industry is responsible for for almost half of the natural gas consumption else side of the production of power. So you're looking to figure out how to use natural gas more. Anomic Lee. You would turn to industry and this also includes the amount of natural gas used as a feedstock in history which is so important. Many people have argued. How can we waste natural gas by burning it we need it. For production of industry and just your material. One of elegy is like using natural gas. To burn electricity is like washing your dishes and champagne. And we need it for better uses. Buildings on the other hand are responsible for the bulk of the electricity consumption seventy three and percent and actually rising there as well it's going on the past two years from seventy one to two to three. And transportation is largely responsible for petroleum use and of course a more compelling number for transportation is that about ninety seven percent of transportation is powered by petroleum. But the flipside is seventy percent of our petroleum is used in transportation petroleum transportation see that kind of three different wedges here around which you can try to figure out a domestic. Energy climate strategy. This is a diagram that Carson or presented at one of the conference of parties to climate change. Where he presents a vision of hell through more efficient energy consumption. We could actually level the energy demand growth in the country in other words we should not ever need to consume more energy than we are today just no excuse for in fact we really ought to be moving to reductions. But there are a lot of ways in which we can quite easily manage our energy the growth of our energy consumption and again he looks at. Buildings industry and transportation and talks about the quads of savings and the technologies available. And I'm going to talk. A little bit about transportation efficiency and in buildings efficiency. I'm not going to talk about industry industrial efficiency for no particular reason. Limited Time. There's been much less effort at analyzing industrial energy use. Actually I chaired. America's energy future. Study Group on energy efficiency and industry where we wrote a sixty page chapter in the efficiency report that's about to be released. And what I was struck in the energy in the use of energy in industry is that any acing Craddick way in which it's used in each of the industrial processes it's very hard to talk about for instance in buildings you can talk about lighting. In the transportation you talk about engines or lightweight materials and and astri there's just so many different unique technologies. There are a couple of fundamental utilities that are used in common. Like steam systems and motors and drives compressed air but they don't really amount to a lot. It's the big industrial processes making steel and aluminum and pulp and paper that are so good. Contributes so much to energy and industry so it's really hard. I haven't yet boiled. That. Material down into something I can communicate easily. So that's my pitch. Or Scotto Marx's that's my pitch and if you know like it. I have another pitch. If they don't like my jokes you. OK so. Efficiency in transportation. Well. Energy consumption in transportation per car and S.U.V. and light truck has not changed since almost since the Arab oil embargo. We insist we instituted corporate average fuel economy standards following the seventy three seventy four crisis and once those goals were met in the early eighty's eighty's we just coasted and that's where we've been for several decades. Fortunately with the energy X. of the last several years. We have now committed to increasing our corporate average fuel economy standards up to. Forty miles per gallon in twenty twenty five. I think is the number. Some say we could go higher and in the America's energy future study we modeled fifty miles per gallon by twenty twenty five because I mean really. We could do it today. We could do fifty mpg today with a plug in hybrid. It wouldn't be particularly carbon free because we'd be plugging in. To our coal plant generated electricity. But actually I was I was talking with our president but Peterson and when he was at the inner city of Colorado he had a plug in Ford Escape. I have a Ford Escape I want his so he. He plugged in at home and he they what they did was to. Replacing the traditional battery with one that would give him twenty miles to a charge. And of course you know he's lugging around a heavy battery so you do have a penalty fuel economy when you're especially when you're running on the gas engine but it was an experiment and quite successful and very it was never you know found stranded anywhere. So there are a whole slew of energy efficiency improvements that can be made to our common car and sports utility vehicle and in fact we have over the past twenty five years improved the energy efficiency of our cars and our S.U.V.s. We have lighter weight. Materials and we have more efficient engines this just that we translated that into larger cars more power more acceleration and so all together we haven't improved our mileage but we have more efficient cars. So if we could find a way as with regulation to require that the efficiency improvements result in. Fuel Economy savings then all of this are indeed much of which takes place at Oak Ridge National Laboratory and here Georgia Tech and universities will pay off. So this is. Motors and inverters and converters for electric hybrid vehicles lightweight light weighting of materials and different combustion regimes to penalize. Penalty penalize efficiency but can improve emissions. And this is a vision of the future if we could move our plug in vehicles. And it's a re power stations that are using solar photovoltaic cells and we have a nearly carbon free transport option. And there's a great system being developed in Israel which some of you may have heard of her this is really. So a couple of auto manufacturers have agreed to redesign their cars so that the battery is in the bottom and. Tween the chassis and when the batteries. Need to be recharged the driver pulls into a retarding station and gets onto a lift and the battery packs dropped out and replaced robotically and within ten minutes. It's back on the road. So how's that for innovation and it's that's here today. Electricity use in in buildings offers tremendous opportunity and more efficient electricity generation is also needed. But today's energy. Today's electricity use. Is highly inefficient. It's really embarrassingly inefficient this is they. Drawing that I did that was replicated and read and energy booklet that the National Academies published last year and it takes this to to Stix from the Energy Information Administration on the efficiency of a typical U.S. coal plant supposed rust. Coal plant and thirty three percent efficient. And then you move that power across the transmission lines in the substations and distribution system and you've lost seven to nine percent more of that electricity and you bring it down from a higher to a lower voltage new music in. Your energy management system and say to light your building with an incandescent lamp and in the end you're putting two or three percent of the energy in that lump of coal to productive use. Pretty said. I can multiply that by three immediately by replacing that incandescent with. With. A fluorescent. OK. OK. I missed one zero zero OK I'm going to talk you through that chart. OK Take your household refrigerator. OK. In one nine hundred seventy the typical twenty two cubic foot house the refrigerator used one thousand eight hundred kilowatt hours of electricity. You don't even get defrost automatic defrost or. Any of the extras right. So through a series of improvements to the technology better cabinet insulation better motors better compressor systems especially the. And combined with is still California state appliance standards requiring that in California the average refrigerator be more efficient than the typical one on the marketplace. And then add federal standards in the late eighty's they ratcheted down and there been one in two thousand and one and one in two thousand and four five so that today. You cannot buy a refrigerator that consumes more than about four hundred thirty. Kilowatt hours. That's the latest. That's about the latest standard. So using less than a third of the energy that we used to use through improved technology and you don't pay any more for your refrigerator that when the. Standards were being debated. Both and the state legislature in California and in the U.S. Congress the manufacturers were in an uproar how are they going to you know how do you make a profit. Their prices are going to go up and no people are going to buy fewer refrigerators. Because cyclists the said story is some of those old refrigerator still alive. You know they're cool your beer in the garage. If they are. Unplug it. But. Where was they going so. This chart shows if we just consider how much electricity we've saved in the average household refrigerator. How much electricity we say. And put a price tag on that in terms of it like. Bill savings. The average bill savings. Per year from that improved future rater is something like seventeen and a half billion dollars. And the value of that electricity. This is a couple of years old. The chart from a few years ago exceeds the total value of all of the hydro power. Of the entire US hydropower system would exceed all of Anwar were to be opened up for oil all over almost as much as the entire nuclear fleet in the United States and that's just one appliance. This is a drawing that our Rosenfeld developed and I really ought to go and probably change a few of the numbers because he's a bit optimistic he gives you the retail price for when you're saving energy and wholesale play price for when you're producing as a little bit unfair but you get the point that Helsel refrigerators been a really big power plant for us and we have many other appliances that could offer the same way of displacing our electricity consumption but the problem is often if you want to buy that more efficient appliance you've got to pay a premium upfront and that sticker shock is what the consumer often can't get past. So you go to Home Depot or Lowes or Walmart and you are looking to replace your bulb and you ask. Well two dollars fifty cents. They're both the equivalent of sixty watt seventy five watts What should I do you know. Still today in the state of Georgia. Less than thirty percent of new bulbs purchased are compact fluorescents. There's no reason anybody in the state of Georgia should buy incandescent bulbs today because look at the payback. This is if you just assume that the bulb is used four hours a day. And you're assuming Actually this is a bit of a low rate seven cents per kilowatt hour you pay a bit more than that now. The little bit it say a five percent discount rate Well the first year of energy costs that incandescent bulb the seven dollars and seventy cents. And for the compact is dollar eighty. So I mean what better place to put your money. Much better than having it in the stock market. I can tell you that. So take a look at a more recent set of electronic options that you can buy for instance how about the plasma T.V. when they finally in December of two thousand and seven E.P.A. added Energy Star rating to the plasma T.V. So when you go and you go to compare plasma or L.C.D. or traditional television you now have a label that you can go and you know that you'll pay a penalty if you buy that plasma compared to the L.C.D.. Flat screen. So what about the set top boxes the set top box. Turns out that it's something you need to pay attention to also thirty watts each path one of those light bulbs. Two of those make up a refrigerator. And made a lot of progress with a refrigerator we haven't made any progress with the set top box because it's uses so much standby electricity that is it's going to pay for seven whether the television is on or not. And so in the class that I teach. Here we use kilowatt meters. And we measure standby use use when the appliances on and you can see how much electricity is being draw on your telephone recharger or even after you've finished the recharging and you learn really interesting things like the electricity consumption goes up when you turn up the volume. Or if you're not getting a very good reception on your television. You're using more energy. And I don't know what you do with that information but. You know we need to be wiser and one way to be more. More effective consumer is to really understand. How much energy you're using it and how much each of those purchases will will use so this is the kilowatt meter that we use in my classes. For each device you just plug it in and you plug your device into it or you can use programmable community Kading thermostats which in some states are part of the smart meter programs. But of course not in Georgia and Georgia are smart meters are really smart readers right there. Replacing. The truck driving by and the guy getting out and reading your meter with a meter that automatically dispatches the information and turns it back to Georgia power but the consumer is not getting any information which is really what's needed. That's really a smart meter. That's the sort of thing we need are these thermostats was real time information keyed into time of use rates and then you would have a motivation to use electricity more wisely. So the states of California and New York. Have done so well in. Managing the electricity especially in their buildings the electricity per person in those states has not increased. Since the seventy's. Since the mid seventy's. Well California since the mid seventy's and New York's catching up. At first. This was Art Rosenfeld graph draw as a graph. It's just that California. But then Paul Dakotas came along. It's the New York State Energy Office and he said look I've been on the twenty years and look what I've done and no increase in electricity and we could do that too but actually George's electricity as per capita is consuming more rapidly than that of the United States we're offsetting you know we're on the top of the chart. So to speak. And they have not done this at the expense of their state. Economies. It's not been something they've done and they have to pay the price. Right. They've done while their economies have been growing rapidly. Until lately. So there are a whole set of other technology options that I'm not going to be able to go through one by one but just in general we call them. Low carbon fuels and electricity options abundance of them. So as shown by this mosaic. Lots of them coming on strong especially when. Fully offshore GA wind sometime in the future. But I am going to talk you see that one too darn I P.D.F. this. That was my mistake. This is a chart on carbon. Capture and sequestration three different ways that you can capture carbon tress real ocean and geologic. So putting it down and aquifers planting more trees. Phytoplankton growth through iron. Nutrients in the ocean laying C O two on the bed floor a bit of the ocean all those options are being worked as an enormous amount of effort trying to figure out how permanent those different Seaquest ration options are and they look very viable no real breakthrough technologies are required. We just need massive pilot tests to see what the leakage rates are and. What is going to cost. I didn't want to fail to mention to mention nuclear even without Yucca Mountain. We've got nuclear as an option and it's certainly possible that we'll see a renaissance of nuclear in the southeast which is going to be significant come contributor to low carbon electricity. So. Turning now to the policies that can help to drive these technologies into the marketplace. One of the big ones getting attention in Congress today is the cap and trade system carbon cap and trade this tie crim from the World Resources Institute. This is a really great Web site to turn to if you ever want to see what's happening with the latest legislation but these for the initial proposals for cap and trade being an inspector being one of the very first. And some of these others coming on later. I worked on the big human specter a bit because it's based on the work. As the National Commission on energy policy. I'm a commissioner. On that and we did that work for Jeff Bingaman largely. Sculpted the whole design of cap and trade systems. Back in our report that was published in two thousand and four. And that led to this proposal. If you see the dash we weren't thinking twenty fifty in two thousand and four we were thinking let's get it in place and. Let's try to first level C O two emissions and then think about turning them down sometime in the future when the American public was ready to take a deeper cut. But these other. Subsequent proposals have taken emissions and their cap and trade proposals all the way down to what people are now thinking is the. Stabilisation goal we need eighty percent below nine hundred ninety levels. Down to one point two billion metric tons by mid century and that's the goal of many of these legislative proposals today. That's the goal of the current cap and trade proposal being debated the Waxman Marky bill. So Congressman Waxman from California took over position this head of the House Senate and energy the House Energy and Commerce Committee and he proposed a couple of months ago. For the first time the house demonstrated leadership. Well you'll notice when you go through the previous graph it's all senators names of senators. And that we have the health stepping up and Waxman Markey in particular. Democrats and they're proposing. To deviate from the business as usual forecast. Along this green line with a cap and trade. But their bill calls for a portfolio of supplemental complimentary policies. And that's what's drawn in the blue mark here it is in order to get to one point two billion tons of C O two the thinking is a cap and trade systems prop by itself probably not enough thinking seems to be necessary but not sufficient. And one of the reasons is if you go through the calculations of the carbon content of transportation fuels. Carbon tax does not move the price of gasoline very much. Relative to the price of electricity. So if for instance you add about twenty percent of the price of electricity through say a. Fifty dollars or so carbon price take that same price and add it to gasoline and you're adding like eight percent. And we all know about the price elasticity of demand for gasoline right. We still a little bit of it for the first time ever. Last year late last year when we were experiencing this very high gasoline prices but I think the public's already forgotten. And they're back to vehicle miles traveled just about where they were before. So you can't move the entire market all sectors sufficiently with just putting across the board price on carbon. You need to do much more and there are some who would argue that in any event. You need to regulate performance standards because we need the certainty of a performance standard to complement the uncertainty of a cap and trade where you can always buy your way out of a limit by purchasing allowances or offsets right and then you don't know what you're going to get so by having performance standards you have a little bit more control and then there are all sorts of other things that we can do that we need to do like education. And labeling and information and sent to us and you know more and more gas guzzler taxes and more incentives for plug in hybrids that sort of thing to incentivize the market and also we need things like. Manufacturers incentives to try to get the production of these green technologies stimulated in the U.S. markets. So that's the nature of those complimentary a lot of that is Clute included in the Waxman Marky bill. So just got about two more slides. This shows you when you put a price on C O two. What that means for the price of different types of electricity so polarized coal P C integrated gasification combined cycle kind of really get hit hard it will drive them out of the market and possibly won't cause the existing really inefficient power plants to shut down that probably has to be done. In a different different kind of policy mood because they're so cost effective. Even when you add a big C O two price because they're all written off you know they're really cheap to run. But look at the impact on efficiency. Stays really cheap. As does nuclear and as do many of the renewables. So this is what's going to be moved into the marketplace with a cap and trade. But less if you walk away thinking we have a solution. Cap and trade complimentary measures to get the picture all solved. Think about the order of magnitude that we're facing. IS MY LAST FEW graph. You might remember that you and I are responsible for emitting about twenty tons of C O two a year. The average for the U.. The world is four. That's now where China is twenty used to be one the average for India is that one where we need to be in the long run by two thousand and fifty is at one. One ton per person to stabilize. The level of concentrations in the atmosphere. At levels that prevent dangerous anthropogenic interference with a global climate. So today we have the world. Affluence rising and as the affluence rises were that picture more G.D.P. more C O two. So we have the African and Indian nations there their movement marchin up and we're kind of leveled off what we need to do is actually step down all the way to the point where. The future rich are at the same level of emissions as today's poor. So that kind of. Magnitude of the challenge is why you are all. Needed to help provide new technologies and transformational solutions because we don't have those yet. Thank you very much. Well I think a year ago I might have agreed with you but I mean we have seen a transformation of our policy environment here for the first time a significant increase in our fuel economy standards. Just yesterday E.P.A. announced they were going to require sixteen billion gallons of cellulosic ethanol to be. We blended in gasoline by the year twenty sixteen while sixteen billion of cellulosic we don't even have one gallon. Today and we have sixteen billion. So we're kind of creating stretch goals I would say and I'm pretty optimistic that we're going to make progress like we've never made in the past with the new new policies in place. I hope this case you know. It's like. It was a moment. When. Well you know all of the credential is that Georgia Tech has some life cycle analysis new city applied to answering these questions so that policymakers don't get snookered by these simple answers because often you can jump to the wrong conclusion. Like you like you said we need to prevent those kinds of mistakes from being made through good analysis and to show what the what the impacts are so there are a lot of advantages to plug in electric hybrids above and beyond carbon and efficiency. And of stabilizing bigger. Rid using We only use half of our electricity. If you look at low duration curves. So you get one hundred percent of capacity use like for five seconds in a year. And it just marches down there using half the. Capacity half the time or have to go. Bessie almost all the time so. Yeah but so I guess. So what I'm saying is that. As we bring us our electricity production. We can be getting a plug in electric created and the infrastructure in place and gradually it will all converge right now the reason that Epperly and Edison Electric consider so excited about plug ins is not because see to tell you but it's because they can sell more electricity and they can set but their existing plants to use more effectively and there's something to be said for that using your energy infrastructure more economically. And then gradually I mean I made the same argument for corn ethanol I'm kind of left myself because it's really going wild. You know let's get the eighty five refueling stations in place and. And then they'll be there. So when we have cellulosic ethanol and we don't have to go through that whole infrastructure we get the pipelines and everything built even if it's corn ethanol bad you know for a lot of reasons. So we have to think about the fact that you can't replace your infrastructure or mediately And so sometimes you have to go through bad stages. To get to hopefully a good in some kind of a rather unrewarding logic but. Every store his eyes. Says. One is. So right now and for instance a traditionally regulated southeast. There is no motivation for electric utilities to do anything different because the people you see provides a reward structure that rewards the sale of electricity. Whatever from whatever source. If you generate it yourself you get a certain return on investment if you buy renewables or you purchase any energy credits. Your profit is less. If you help customers use electricity more wisely and you sell less you profit less so there's a couple ling of sales and profits that has got to be changed and I mean that is just such an obvious is true with water too. You know we can see. Less water and the rates went up because they the water utilities get their profits from sale of water and electric utilities get profits from sale of electricity. So all of the hall reward system has got to be changed and the Philippines should be paid to provide energy services which are lighting and cooling and heating not to not to sell electricity or sell natural gas. I know you know that argument. I think that's in my opinion that is the single most important barrier in policy today and it was addressed by the stimulus act. You probably know this but every governor. In the state before receiving stimulus funds had to write a letter to Steven Chu. Stating that in their state. Efficiency received the same return on investment for utilities as the sale of electricity and Sonny Perdue signed that letter. And it may be challenged because it's not true. But every governor signed that letter and there are only about eight states that have decoupled sales and profits in the electricity industry. So you know that Obama. Understood the problem but now we're down to the point of enforcement and that particular policy supposed to be fixed but you know. If the fundamental premise of greenhouse gas. Impacts on Global. What is then. There's no point in going to a university and studying science. I mean I just so preposterous. But what if. Well you know I have wasted some money and that's a argument for doing nothing. You know. THIEF. Of time the argument is this wait and see and then if it's really bad. We'll just build the seawall so that much higher but that's a pretty expensive price tag too and the so I think you know there's a lot of thinking along the lines of as you said and it's a really good way to think that is the risk risks of different outcomes I just think that the idea that we're not impacting the climate in the general way is that we think we are such a. Well that's because the answer for genic impact on water vapor is not as great and so is the anthropogenic impact of solar this solar radiation is. It is also a important. Contributor to global warming but and I know. The answer but genic forces are ten times the force of changes in the solar radiation. Since the Industrial Revolution. You can see that in the I.P.C.C. report. So it puts it into perspective the change in a water vapor is so minor relative to the change and forcing the climate forcing of greenhouse gas emission. Concentrations constant concentration increases. And we're really grateful for the water vapor being there. Otherwise we wouldn't be alive on the planet Earth but if you were it's your fault and the variation. Really there's a real regulation to that we're live from that three percent make their twenty dollars a barrel rate I think yes program that you want to run if you want to that you're going to jail for that and they will tell you your comment percentage of average rate versus taxes that average what you think is the best way to go. The best way to go is to put a price on carbon tax or cap and trade I prefer many of the features of the cap and trade but what I'm most concerned about is that we implement a price signal. So that the consumer. Well internalize the costs of global warming into their decision making. Well the best thing would be done it. Yeah and the best example is that the Clean Air Act and the market for sulfur dioxide which has been very successful and quite mature but you know right now we have very a mature markets for C O two and the prices are low and hard to make a business you know but that's because it's all chopped up and regional and unpredictable that stat. Certainty you talked about is what we need before people really commit sizable amounts of capital to to make these low carbon products as well a lot of the cost related. Well that's a little less because there are some estimates emerging and there's there's not much volume of work going into the cost of inaction. Stern Report is one example. And there's been a couple of others and there's a review article I can point you to an energy policy but really the bulk of the work in that area has not been sufficient partly because well first the U.S. doesn't even have a program on climate adaptation climate change adaptation. We have. The Europeans are way ahead of us they. I had a chance to go to the conference of the party six in the Hague. That was the year two thousand and it was full of all of these illust these exhibits on how to minimize the cost of global climate change and how to adapt. We have not begun that's what you need you need all of this costs lined up. So how do you save species from extinction and and how do you manage your water and the droughts and you know level rise and now there are some. There is a group the. Legislative group that's been doing state studies they're putting together existing literature for their state legislators. Conference of State Legislators National Conference of State Legislators and they did one for Georgia. And they talked about the costs of protecting our barrier islands. And the cost of the savannah. Port activities were there to be a rise of some foot or something. Sea level rise. So we're beginning to see some cool price tags being put on but it will cost to prevent the flooding of barrier islands for instance Carlos you had your hand up. Can I call on you. What do you see. You should see. A vision to see that that's true. It's a little bit like population control. You know and it's just seen as not something that. The government is supposed to constrain. You know it's supposed to change your your cultural norms or. Value system. Which is what you do when you can appreciate the materialization there. I know that's been a theme of yours. I really like your work on how much a person really could get by with in terms of C O two per year for survival and a reasonable lifestyle. I think your number was like four or five times a C O two whatever it was I've seen you march through that and that's I think it's good to do those and to. Kind of assessments and to show. That. Cultures across the world are living at that level reasonably well but if the government. You know doesn't have policies doesn't. Condone policies like that. Yeah yeah well I think that air conditioning is the next really big appliance that we should tackle cooling is the. Well and home space heating still prevails in energy and in commercial buildings it's lighting. But in both cases cooling is the next highest use for energy. So it is really an important and it's also one of those ways that we can adapt to climate change because we're going to need more cooling and so we better find efficient ways to cool kind of a double digit in. Concept. But we're going to do better campus is going to do better. There you know. Another big ticket item for appliances is a gas furnace. The current current standards are eighty percent and you have witnessed a condensing gas furnace is it can go up to ninety nine percent. I know I had one when I bought one myself and then I bought a house and I had to. Eighty percent model. So if so much it can be done. I did want to say that I've got a group of students here. They came from public policy. Thank you very much. And they're working with me getting up a national energy modeling system out over in the D.M. Smith building we have got up and running two computers with a modeling system. We are one of as far as I know in the university for the capability others. So we're really trying to gear up to be able to help answer these questions of what can a cap and trade do versus what can these other policies do and together. How do they operate so stay tuned. We should be spinning out good stuff in the next few months. But we're all going to recycle all right OK Thank you.
