Alternatives to nuclear power for slowing climate change
The US can achieve large reductions in greenhouse gases, not to mention energy costs, from conservation measures. Geothermal energy, from hot rock and water below the Earth's surface, is a source of steady power, has a long track record, doesn't generate greenhouse gases, and is being rapidly developed. It's also becoming more economical with tax incentives and stimulus money. Although geothermal plants have a high up-front cost, the cost of energy generated from them is less than for coal, as outlined in this Scientific American piece. Other potential solutions to the problem of solar and wind being intermittent include using hydrogen fuel cells to store the energy these sources generate, and pumping water uphill when solar and wind are available and generating power by sending it downhill when they aren't.
Nuclear power still has all the issues that it had in the 1970's and early 1980's: no long-term solution to the problem of waste, very large cost of building plants, and safety issues with operating the plants and mining uranium. Also, though nuclear plants don't generate CO2 during operation, mining and processing uranium with current methods does generate greenhouse gases. Some sources point to fast neutron reactors, which potentially solve the problem of waste by producing more fuel from depleted fuel, as the wave of the future. However this article points to serious problems with these reactors which have resulted in the closure of most of them since their introduction in the 1950's.
With the track record of geothermal, new methods of storing energy from solar and wind, conservation, and new sources of energy being developed, I think we should be very cautious about pursuing a technology which has the potential to release significant amounts of radioactivity for millenia. What do you think?

Sustainable Cooking and Junk Mail Follow-up
Brighter Planet, a group from Middlebury, Vermont that helps people mitigate their environmental footprint, recently published a guide to Mastering the Art of Sustainable Cooking. Inspired by Julie Powell's book and the movie Julie and Julia, the guide shares information and recipes from hundreds of contributors to help us lighten our "foodprint." According to the guide, "The average American is responsible for about 28.5 tons of carbon dioxide emissions every year, of which 20 percent, or 6.1 tons, is related to food. That’s greater than the impact of all their driving and flying habits combined. This might be surprising, given that public discussions of carbon emissions focus heavily on transportation while discussions about the impacts of food are typically centered around non-climate issues. But what it means is that individually and collectively, there is huge opportunity to reduce our climate impact by changing how we eat." Take a look, share by posting a comment, and

International Day of Climate Action October 24
In Santa Fe, meet at the Center for Contemporary Art, 1050 Old Pecos Trail, at 1 p.m. (noon if you want to volunteer) for a human 350 postcard photo, march to the Roundhouse and rally. Bring signs that say 350, ride your bike or the bus as far as you can, and wear green or blue. Click here for more info. See you there!
I'll continue countering myths next week.

Solar Fiesta This Weekend, Go Green Action Tips
The NM Environment Department hosts Go Green Action Tips, a series of audio clips covering a wide range of topics, including water pollution prevention, limiting your mercury exposure, and a Green Vehicle Guide. Did you know that you shouldn't dispose of fluorescent light bulbs in the trash? They can be brought to the Buckman Road Recycling and Transfer Station for recycling seven days a week, 8 am to 5 p.m., free for Santa Fe County residents. Or save them for your local household hazardous waste collection day. Each bulb has a small amount of mercury in it, and this mercury is released to the environment if the bulbs are disposed of in the trash. The mercury from the large number of compact fluorescent light bulbs now in use could be a significant threat to the environment. However, the amount of mercury released from burning coal for electricity to power the same number of incandescent light bulbs would be six times as great, and the amount of electricity used would be four times as great, according to Progress Energy, a company that owns two electric utilities. Since 57% of our electricity comes from coal, the mercury savings from using fluorescent bulbs are clearly significant.

You also might want to read an article from the online version of Der Spiegel, one of Europe's largest weekly news magazines. Click here to read Spiegel's interview of Hans Joachim Schellnhuber, a world famous physicist, climate researcher, professor, and the German government's top adviser on climate. Schellnhuber says that even Germany's targets for CO2 reduction aren't enough, and tells how even greater reductions can be achieved. In response to the interviewer's question of whether he's an idealist, he says: "The WBGU is not political; we merely advise the government and present our studies and findings to the public. Our budget has nothing to do with utopias but rather with the physical conditions under which we can prevent our civilization from crumbling." It's interesting to read articles from Europe, where there's really not much debate on climate change, except how to reduce it. Remember, humanity has come through many challenges; let's keep each other informed and encouraged to take action to meet this one. Send me your thoughts and actions by commenting below, and

Don't let them forget
We need to remind our Congressional representatives and Senators that as important as health care is, they can't forget about the critical American Clean Energy and Security Act (ACES for short). ACES, the first national bill that would curb global warming, passed the House on June 26, 2009. Now we need the Senate to pass it. (Obama will sign it if it passes.) The bill needs strengthening, but there's a lot of pressure on the Senate to weaken it further. Please, click here to find your Senators and either attend a town hall meeting or contact them directly to pass as strong a version of ACES as possible. Or, click here to send an email.
The fossil fuel industry is throwing a lot of money and influence into opposing this bill. The idea isn't to eliminate the use of fossil fuels anytime soon--we don't have enough alternatives developed yet. It's to develop incentives for reducing our output of greenhouse gases and develop alternative energy sources that would also provide jobs so that we can fight global warming, which threatens to make all our other problems seem insignificant. Serious effects are already being felt, and the consequences of business as usual would be dire for the human species as well as many others. Because of delays that are built into Earth's climate system, if we wait to act until the most serious consequences arrive, it will be too late to reverse them. We need to act now to prevent the worst consequences of global warming from happening. Let me know what you're doing to reduce global warming!

Is "Cash for Clunkers" Good for the Environment?
Making a new car produces greenhouse gases, of course. If you trade in a clunker getting 18 mpg for a new car getting 22 mpg, it would take about 5 1/2 years of average driving to save the amount of greenhouse gases that went into manufacturing the new car, according to the dean of the Nicholas School of the Environment at Duke University, William Chameides, quoted on NPR here. After that, you would be reducing your carbon footprint. With trucks, it might take eight or nine years, Chameides says (trucks usually have more material in them and more greenhouse gases are produced in their manufacture). With the median age of cars on the road in the US older than ever at 9.4 years, and some of the new cars purchased getting more than 22 mpg, the net result is positive. However, the Associated Press calculated that the greenhouse gas savings from this year's cash to clunkers program would reduce the nation's greenhouse gas emissions by only a few hundredths of a percent, assuming 500,000 to 750,000 of the 260 million vehicles on the road in the US are traded in.
If you traded in a 20-mpg car for a 50 mpg hybrid, however, you'd make up for the greenhouse gases produced in manufacture in 20 months, according to Gil Friend of ClimateBiz. The greater the difference between the fuel economy of the old car and the fuel economy of the new car, the greater the savings in greenhouse gases. The longer you keep your new car the better for the environment, until there are newer cars whose efficiency is so great that it makes sense to trade in again. The savings with cash to clunkers is not as great as it could be - the original legislation required new cars purchased to meet stricter mileage standards to qualify - but it's a small step in the right direction. And it definitely makes sense for individuals to junk gas guzzlers and buy the most efficient vehicle they can, with or without a government program.
