It is clear that Nordhaus and Shellenberger are neither delayers nor deniers. Their alarm about global warming is as urgent as that of Al Gore. Where they differ is that they think Americans won't respond to a message of doom and gloom. Much of this is coming from the authors' background as political pollsters

Mark, your piece makes some good points but you don't go near far enough. You focus on solar power, ignoring the fact that solar PV is by far the most expensive of the renewables. Wind power, geothermal, and biomass (particulary landfill gas) are highly competitive today with fossil fuels in California, according to a recent report from the California Energy Commission. Solar PV and concentrating solar power are still more expensive, but coming down.

M&S are way wrong when it comes to California b/c new coal plants and imports are already verboten here (unless they sequester CO2, which isn't currently feasible), making natural gas plants the fossil fuel competitor. The Utilities Commission just finished its annual analysis of the cost of new natural gas plants, finding that electricity from new natural gas plants costs 9-10 c/kWh, making wind, geothermal and biomass highly competitive.

Just imagine what could happen if we invested trillions, or even half of the trillions spent on waging a war over oil in Iraq. Unfortunately our priorities are still stuck in the mid-80's, at least the priorities of the lawmakers on capitol hill, not just in the white house.

Thanks for those comments. Yes, some renewables are cost competitives and others are on their way. Yet I still think that S&N are right about the Apollo-style investment that is needed. There is so little time. But thanks for bringing me up to date.

Indeed, and these <15mpg SUV's are out on the freeways doing 80mph, not the fuel efficient 55mph of the 80's when oil cost how much...?

I've just spent an afternoon at the State Fair of Texas, (the first for me in some twenty years) where I found myself wandering thru several large buildings filled with new 2008 autos and trucks. I saw only one hybrid vehicle, no electric ones, and a sea of SUVs and oversized trucks. Many of the SUVs stickers showed no more than fifteen miles per gallon city driving.(these were mid-sized vehicles). Many of the trucks such as the F250 and F350 and Hummers do not even show mileage. One sticker said it was not necessary.
In twenty years if anything conditions have deteriorated. On a day when the price of oil reached $89. a barrel, literally hundreds of smiling potential customers were fawning over a sea of global warming nightmares. Not a single complaint was heard.
If, as I believe myself,conservation must go hand in hand with new energy effective technologies, the hour is indeed late. All our efforts over all these years may be no more than a drop in the bucket. Sobering isn't it.

OK. All of the above, with the exception of the Alcohol and Bio-diesel, are prohibitively expensive to obtain and install. None of the big three, PV, Wind and Methane, can really be fabricated at home by a determined handyman. And, none of them can, at this time, be financed easily in the state of Texas.
Until the common man and his family can install these systems in our homes, we won't have a true solution. THAT is what we need the APOLLO financing for. Accomplish the grassroots installation of green energy and the problem SOLVES ITSELF.
Ok, I'll shut up now and let somebody else talk. Well done, all.

Bernard- That's great! Wouldn't it be nice if the 'common' man could afford tech like that?


MOST of the folks here have had good, thoughtfull things to say, and this kind of conversation is what's needed on these issues. One of my biggest beefs, personally, is the lack of or chronic under-funding of any sort of financial plan that will allow joe blow citizen to take advantage of these industries. I've got a small farm in central Texas, and would LOVE to be able to make myself totally self sufficient with respect to my energy needs. That would require: Gas or electricity for heating and cooking, obtainable via 1. PV, 2. Wind Generation, or 3. Methane generation; Electricity for my household and outbuildings, obtainable from PV or Wind; and Fuel for my vehicles and tractor, available from either Alchohol still, Bio- diesel, or, if I could convert to electric (?), PV or Wind.

Lura- Bravo! That needed saying to ALL of us.

John Carr- Your latest is also true. Your first, however, while always relevant, doesn't cut it as far as concrete actions toward a solution to either global warming/dimming or effecting a rapid transition to green, non-polluting, renewable and affordable energy resources.

Todd Cory and Tom Kunhardt- You guys are right on the money as far as your emphasis on 1. Conservation, 2. Recycling 3. Passive technologies for enhanced insullation and heating/cooling and 4. Sustainable living practices, Green building, sustainable agriculture, and water resource management. I think though, Tom, that you should re-examine alcohol production. I've got a small still that I put together for less than $20 that produces 3-4 gallons an hour from inedible food garbage or most anything else organic that you put in it. The final product cost well less than .50/gallon.

This strand of responses is exactly what S&N were talking about. The environmental community is fractious and driven by technical, rather than core value, issues. It's like everyone is talking past each other. People in this industry tend to get bogged down in the minutia, or defending their ideas and technology.

The renewable energy pie is small. Let's stop arguing about the size of each piece. Let's get more pie.

Marty -

I have never in my life seen anything that is 100% certain. Have you? Do you operate your life that way? Only investing in a 'sure thing', rather than weighing the risks and benefits in a given action and then moving with a plan in the best possible direction given the information you have available? Not making a decision is a decision in itself. Even if by some chance scientists are not totally correct on the exact causes of Climate Change, can you deny the need to do something serious about our energy costs (both financial and political), the pollution in our skies, and the health of the planet as we continue to pour deadly substances into it in the name of cheap energy?

I think it matters LESS what the cause of climate change is, and MORE what all the effects our current energy use are.

The technologies needed for making high intensity PV concentrators fully cost-competitive with coal-fired power have been developed and proven. Silicon vertical multi-junction (VMJ) cells with output power exceeding 200,000 watts/m2 at 1000 or more suns intensities has been demonstrated (www.photovolt.us). Having an output power a thousand greater completely alters the existing high $/watt cost of solar cell technologies for the better. There would be no silicon shortage if you can install 1000 MW of PV concentrators using the silicon now needed for 1 MW of conventional PV modules.

Making PV power cheaper than coal-fired power is realistic, but will need the right leadership and commitment to make it happen.

That should have read, "if over 50 years a $500 panel puts out an average of 400 watts a day and the average cost of a kWhr over that time is 20 cents then the value of the energy is $1460 which is a savings of $460 if the balance of system components cost $500. Not a bad deal if you consider that you also reduce global warming.

One more thing, PV is the most durable, low maintenance technology devised by humanity. The first system I built is still in use after 25 years. With warranties up to 25 years, these systems will be putting out a significant percentage of their original ratings for generations. So if over 25 years a $500, 100 watt panel puts out an average of 400 watts a day and the average cost of a kWhr over that time is 20 cents, then the value of the energy is $2920. if the balance of system components add $500, you still are up by $1920. If the panels continue to put out for fifty years..... Well, you do the math.

It strikes me that the answer isn't either / or, but both. European countries have had far higher energy prices than us for decades and are also far more energy efficient. In addition, the success of cap and trade at reducing acid emissions suggests that it can work, as well. Therefore, I fail to understand the logic of dismissing the potential of this approach based on Europe's first, tentative experiment with it. I also fail to understand why they would cast the issue as either / or. Clearly, the solution is to internalize the cost of carbon (at whatever price it takes) and invest heavilly to ensure that the price is minimized.

I forgot to mention that I have been designing these energy systems and using them for my own home during the past 25 years. Now working on a modular version that packages all the components including energy storage in a single box. Anyone interested? joncole@gmail.com

PS. it doesn't even matter if human activities are contributing to global warming. It only matters that it is coming and it is incredibly disruptive and dangerous. So let's quit quibbling and roll up our sleeves and get to work to reduce global warming!! That means a reduction of greenhouse gases which is probably more rational than turning down the sun. Which is also happening by our world-wide pollution. Its called global dimming.

First, PV is not expensive. For about the price of a new small car, you have PV energy for one person. The price/person is cut in half for each subsequent person in the household. The storage problem has now been solved with safe, green, no maintenance, highly efficient lithium titanate batteries being able to last as long as the PV. The main problem is finance. The utility companies have energy technology finance available from the financial markets. If we create an energy system mortgage instrument, which gets securitized (like home mortgages) then PV becomes a monthly payment akin to the monthly utility costs. Or if you want to pay cash, then you get zero energy cost after 5-7 years. Did I mention that energy conservation is part of the package?

Yes Tom. I agree, batteries and renewable energy sources to charge them. And by the way, in case anyone is wondering why ethanol is currently the belle of the renewable fuel ball, do the energy equations on producing ethanol from corn. You'll be wondering if you've missed something. Next look up these three letters ADM (Archer Daniels Midland) and follow the money trail. You now have the answer.

I see a future with huge amounts of solar PV that provides energy for electric vehicles. This provides fuel for two primary forms of energy consumption, electricity and transportation. (Ethanol is NOT a viable transportation fuel because it requires using food for fuel and consumes huge amounts of water.) I won't even get into the geopolitical benefits of a solar electric future.

This vision requires Apollo scale investment in PV and battery technology. We need to invest in all other forms of clean renewable energy to provide base load power to the grid.

Today in the USA our rate of resource consumption requires more than four planet earths. In Europe their rate is about two. So, the focus for us is expanding clean renewable energy AND sustainable living practices in every aspect of our lives.

We do need Apollo scale investment in renewable energy from our government and the private sector. An issue that gets little attention because of the disagreement on Global Climate Change is resource depletion. We need Apollo scale investment in sustainable living practices. Green building, sustainable agriculture, and water resource management (I don't mean privatization of water rights, quite the opposite!) to name a few.

This can be seen and measured in very real terms. Global population is six billion people, 90 million more every year; in 50 years we could be at nine billion. Most of the growth is in developing nations where food and water supplies are currently outstripped by demand. Marine species and fisheries are precariously close to collapse. Water is increasingly scarce around the globe. One billion people (1 in 5) do not have access to clean drinking water, today! http://news.bbc.co.uk/hi/english/static/in_depth/world/2000/world_water_crisis/default.stm

Ummm, I know this is a dirty word here in the land of waste and unconsciousness, but the cheapest new energy is conservation and efficiency improvements. Unless these are job one, trying to compensate for waste with "green energy" is more of the mindless behavior that got us into this mess to begin with. No, this is not as sexy as a rooftop of high tech PV's but it does make the most sense.

Second is solar thermal... and lastly high tech PV.

We need to consider the energy investments to make green energy, and choose wisely those things that offer the largest return.

Wake up everyone. The market got us into this climate crisis and if you think it will get us out, you are kidding yourself as much as Bush is about his rotten war in Iraq. The fact is that we have to have social policies that restrain the greed and short sightedness that characterizes market behavior and stock holder interests. Sure there is money to be made in renewable energy, etc. But not as much and not as fast as in oil. The longer the market rules, the longer it will take us to have any significant impact on the environmental crisis. Whatever happened to public interest, public planning, social responsibility? The current political trends are dead ends. Let's take off the blinders and start to act like the social beings we are. Poverty and the global climate crisis are the same crisis. We will solve both or neither. I believe we can do it if we set our minds to it. Without clarity, though, the marketeers will continue to take us down this ugly path we are on today.

Hey Mark, I found another article that seems to take issue with your conclusion that Man Made Global Warming is no longer debateable. This seems to be a common tact by many: marginalize the opposing opinion instead of debating the issue. The debate is not over.

A vision that grows our economy so we can afford the cost of health care, and pay for the looming social security short-fall. Investment in technologies that drop the cost of clean energy are the key.

Most people will ask, "How can talking about it make a difference?"

Simple, politicians listen. Investment bankers listen. Manufacturers listen. They are all people, like you, who are staring at the unimaginable wondering how to make it happen.

First, we need to get everybody looking in the right direction and talking about the GREAT future we can make for ourselves and our children!

Dominic,
Do the mass balance. You've changed nothing, except that trip down the river de nile.

Jake & Eugene,
You seem to get it.

I've written numerous times on this site about the scale of the problem and the absolute need for spurring investment, and changing the entire conversation. I think, when most people see the scope of the problem their brains freeze. After they filter out the unimaginable, they start talking about their proverbial fingernails, like Nick.

I completely agree with S&N. Few know what to do next? I'll tell you. It's something anyone can do. Change the conversation with your peers. Start talking about what's in your dreams. By the way, dream big. Get a vision of the future that doesn't use global warming as a rational to change, but corrects it on the way. A vision that creates jobs, opens new possibilities for the future.

Pollution is an abundant resource. We know that CO2 when split gives 2CO which is Carbon Monoxide, and it is used extensively in production markets, and it also is a fuel, that can be burned in cars and trucks. Carbon Monoxide when its burned turns back to CO2. There is a HUGE market with a Huge amount of pollution; which is a resource for fuel. And what are we doing? NOTHING! Quite irresponsible, ignorant, and shameful. See my article: Global Warming is a Blessing!http://www.opednews.com/articles/life_a_dom_jerm_071012_global_warming_is_a_.htm

Pollution is an Abundant Fuel Resource.Its amazing to me that people do not believe Global Warming is real. If they only go to some major cities and look in the skyline all you see is smog, pollution, faded buildings, and a blur on the horizon. No its not bad eye sight it is smog, a major contributor to Global Warming. It is real. We unload CO2, N2O, CH4 into the air and do nothing to take it out? What's wrong WORLD? Can't make money from it? Wrong again...We can suck that stuff up and make Dry Ice from the CO2, we can use N2O which is Nitrious Oxide to help burn in combustion in the engines, and we can use CH4 which is Methane Gas to use as a fuel.

I wrote an article on how CO2 can be made into dry ice, or made into a fuel. Most of the smog is CO2 and N2O and CH4. They are fuels. Remember science class? Gas can be change into a solid. CO2 can be made into dry ice, when split becomes 2CO, this is a fuel. CH4 is methane gas, and N2O is nitrious oxide which helps combustion in car engines. They need to setup a Giant Air Exchangers in major polluted cities that sucks in these pollutants and changes them for use. If we continue putting toxins in the air, why can't we reverse it, and suck it in? The products from it are fuel and dry ice, certainly saleable on the market. Come on what is the matter with us?

The statement that renewable ("clean") energy must be able to compete with "dirty" energy on a level playing field says it all. If locally-generated (homes and industries) solar power could compete one-on-one with the grid, the grid would die in sunny places. And the technology is on the brink, but it does require a massive effort to push it over the edge. A couple of scientists and even Exxon aren't going to be able to solve 131 million cars and 9 million barrels of gas a day. Probably 2 Apollos - one mobile energy and one fixed energy.

House heating with $1/ft^2 Dynaglas "solar siding" can be 100 times less expensive than PV, per peak watt.

There will never be a commitment to alternative energy on any scale in the U.S., let alone on a scale like Apollo or Manhattan. Prohibition was to eliminate alcohol as a competitor of big oil/gas. Reagan/Bush removed the solar panels from the white house that Carter had installed. W spends $500B to kill people in Iraq to try to control oil, yet won't spend $5M to help poor kids get medical insurance. EVERYONE in DC is bought and paid for.

We must take care of ourselves. Solar panels on your house instead of that new SUV. Alcohol stills or electric to run your cars. I've done the solar panels, I'm working on the alcohol still. What have YOU done for your country lately?

The research shows that CO2 from utility power is larger than from the transport sector. Anyway, we now have the Lithium-titanate battery technology that is appropriate for plug-in hybrids which definitely can be charged from a home based PV system. As a matter of fact, by combining IT with power systems we can create systems in which none of the power is wasted as it is now. Whenever power is generated for which there is no immediate demand, it can be saved to specialty battery packs for quick vehicle recharge or shunted to other purposes such as generating hydrogen fuel for cooking. All of these things are doable now with existing and demonstrated technology. These technologies await integration into marketable, approved, modularized systems that have very low-cost installation and extremely long life with minimal maintenance. We can do this if we have the will. http://lightontheearth.blogspot.com/

Dominic,
I've been developing new technologies for about 30 years. I would encourage you to stay enthusiastic in spite of the nay-sayers like me. If you choose to develop new technologies, as I have, you're going to need every bit of your optimistic energy. Others will take if from you, if you let them.

Your Algeoil sounds like a good idea: Stay with it. Reducing your cellulose based Algeoil to aliphatic oil will require some sort of reduction, probably via pyrolysis. It's not overly complicated.

Your idea for converting CO2 to CO and burning it in the presence of carbon is an 80 year old coal process. The coal people called it, "water gas." Fischer-Tropsch begins with forming water gas that's used in hydrocarbon synthesis. It's a high temperature pyrolysis process. There's a low temperature route as well. It's call Low Temperature Carbonization, refer to Lewis Karrick on a Google search. Frank Gentry wrote the last, best book on it in 1928.

Good Luck!

PV electric is fine for home use, but the majority of pollution is coming from our vehicles, and factories. So given the debate, lets focus on the major problem. PV in my opinion is a done deal and is good, but it solves nothing in concern to transportation fuel needs. PV home charge Electric cars do not move goods across country, do not run trains, or airplanes. Ethanol is not enough, corn isn't the answer. Algae Oil is not the answer because you need Ethanol to mix with it to make Biodiesel. Answer is CO2 split to make 2CO and methane gas for our fuel. The supply will never end.

John you do nothing with this comment, because the pollution is already in the amosphere. It doesn't go away. It just build up. I simply have another way of solving the problem, by getting either using the CO2 in our atmosphere as a fuel for our space program, or change it to dry ice and send to the sun or space. Problem solved CO2 is reduced in the Atmosphere. Another problem with these comments, everyone talks PV's and solar, while others talk Ethanol, and Oil. We have two separate issues.

What I do see is a day when the Oil supply in the ground ends, and when that happens we are in some trouble, because then we are relying on alternative energies that do not produce CO2 a basis for life and plants on the earth. Winter time is a major down time for us because plants can't grow to suck out the CO2. Perhaps we need to use alternative fuels in the winter, and the remaining oil resources in the warmer months to balance, until we run out of Oil. Yet another reason to figure out how to stop dry ice sublimation. If it is possible, CO2 could be stored for later use and not in a gaseous state

John check out this site: http://digg.com/environment/Venting_Our_Carbon_Dioxide_Problems_into_Space

Without sounding ignorant I have some major problems in understanding this. First CO2 is a problem by environmentalists, but when you read the above URL you will notice a scientist came up with a simliar idea I have in getting rid of excessive CO2. Thereby reducing the Gas and reversing Global Warming; but the same environmentalists think it is a bad idea! Now I am confused. And while the environmentalists all are pushing for renewable alternative fuels and using Solar, those very fuels produce no CO2. Their plan is as flawed. Without creating CO2 we are essentially depriving ourselves of needed CO2 for plant life. Am I wrong on this? I don't think so. As far as reaching a balance I do not see plants sucking in 14 mile away greenhouse gas circling the globe.

Hey thanks John, I needed that information. If I could make an engine that runs on Carbon Monoxide fuel, wouldn't that be interesting! Last night I was tossing and turning in trying to figure out how to stabilize dry ice. Any ideas? I want to stop it from sublimating. There must be a way. If they can slow it down, it can be stopped. Then I got to figuring really I want to make it back into a solid. That would entail splitting CO2 into 2CO which is carbon monoxide, then splitting carbon monoxide to make solid carbon and O2.

I hate to interject something very negative, but it needs to be out there. It's time to stop arguing, and start locking in the money needed for expansion in the coming depression.

That's right, depression. It's not political. If you believe that consumer spending drives the economy... Then demographics plays a major role in the direction the U.S. economy is headed. In about two years consumer spending will begin a very steep dive downward. The baby boomers are passing their peak spending age in 24 months.

Whoever gets elected in the next cycle will probably get blamed for it, and every bad thing their opponents can dream up.

I bring this up for those who have a rose colored view of the future, and believe we can wait. The stock market will tank. Money will tighten. Don't believe it? Robert Reich is moving his money internationally in 18 months. He said this in Dallas, on Thursday.

Dominic - try looking up "Carbon Cycle" - I don't think anyone's seriously talking about eliminating all CO2 from the atmosphere. It is an essential component, but like a lot of essential things, too much (like too little) has negative consequences, in this case effecting the energy balance between what the Earth receives and what is re-radiated to space. Proposals for big scale projects that will draw CO2 out of the atmosphere need to be extremely well thought through as there will almost certainly be consequences besides reduced CO2 levels. Changing Ocean chemistry for example could be potentially catastrophic to marine food chains. Personally I think better technology that puts out little or no GHG's is vital if only as a first step.

This sounds a lot like the proposal by the late Prof Richard Smalley - nanotech pioneer and nobel laureate - to engage in a Manhattan project style effort to find solutions to the problem of long term clean energy provision. The problem is urgent, we really need to see those alternatives reaching the large scale emerging markets for energy before thousands of new dirty coal plants get built in India, China and elsewhere. Given the scale of the problem the investment in R&D is appallingly small, yet the well of innovation in renewables - and energy supply technologies generally - is far from "peak" production let alone headed for decline. Sliver cells, Crystalline silicon on glass, roll printed CIGS, organic solar cells all show promise, without any one superior technology standing out. Or the back to basics style systems like Ausra's solar thermal or Geothermal's reliability and simplicity. And new ones keep emerging. I don't think we can wait 20 or 50 years to get this right.

This is for all the scientists in renewable energy, expecially the ocean renewable energy program. Underwater turbin windows to harness the kinetic energies of the earths' ocean currents. Thus creating enough electricity to supply the world demand. The underwater grids could be routed to all countries in need of electricity. This alternative energy source would be endless and constantly renewable.
