Climate 411

We received quite a few questions in email about the new technologies I described in our video series, Unleash the Future. I responded to questions on specific technologies in comments to the relevant blog post (solar, biofuels, geothermal, and wave). But there was one important question that applies to all the different technologies:

I’m a firm believer in alternative technology to reduce world wide dependence on fossil fuels, but with our present knowledge of the negative impacts of past innovations due to lack of foresight, what precautions are being taken to make sure that 50 years down the road our grandchildren will not be mopping up yet another mess or suffering from health problems due to compromised ethics?

Gas prices are sky high, as everybody knows, and the main reason is increased demand. But the solution is not to resume offshore drilling in the U.S., as the current administration suggests.

Environmental Defense Fund President Fred Krupp discussed this issue in a PBS interview last week with Charlie Rose, and again in a guest post on Grist. Here’s an excerpt from Grist:

Almost every renewable energy resource begins with the Sun. Wave power is a third conversion of solar energy. The Sun creates the temperature differential that produces wind, and wind, in turn, produces ocean waves. Inventor Alla Weinstein found a way to convert the up-and-down motion of waves into electricity.

Take a look at my short video on wave power to learn more.

While solar, wind and wave energy all originate with the Sun, the heat locked up in the Earth itself offers another huge potential energy resource. Historically, that “geothermal” power could be converted into electricity only in those rare locations where natural fissures allowed water to flow into deep hot rock and come to the surface at temperatures high enough to generate steam. Now an innovator in Alaska has developed the first low-temperature geothermal power plant, which United Technologies is commercializing for worldwide sale.
