What’s a sensible US strategy for climate change and peak oil?

climate changeIt does not have to be mysterious anymore what the US, and by implication, the world can do about climate change and peak oil. It is to deploy the appropriate amount of wind, solar, and electric transportation. With this strategy, we have the knobs for all the results we want: less and less carbon dioxide, and reduced need for oil. What more do we want?

Naturally, we must answer two key questions:

  1. How much would it cost?
  2. How do we deal with wind and solar intermittency?

It used to be that wind cost too much and solar cost way too much. Those days are gone. Now wind costs about the same as new coal plants (which is to say, as little as anything to make electricity), and solar costs (depending on local sunlight) only about half again more. (Of course, in less sunny places, solar prices go up significantly. This is why you hear so many different economic numbers quoted for solar. Small systems are also significantly more expensive than large ones, although most of this is the cost of middle-men and not hardware.) (more…)

EPA’s New Mandatory GHG Reporting Rule and Solar Energy

Smoke StacksIndividuals interested in solar energy and climate policy are likely aware that the U.S. Environmental Protection Agency (EPA) published its final Mandatory Greenhouse Gas Reporting Rule in the Federal Register on October 30, 2009. (74 Fed. Reg. 56260) This regulation represents the first U.S. effort to require public reporting of certain greenhouse gas (GHG). However, few of these observers may be aware that the final rule will not require the tracking of progress by electricity consumers in reducing greenhouse gas (GHG) emissions by substituting on-site solar energy for purchased fossil fuel-fired electricity.

Nonetheless, a close reading of the final EPA rule indicates that solar energy supporters should not pack their bags and go home. Although the final rule is focused on direct emissions from electric generation sources, the Agency signaled its interest in conducting a future rulemaking to address the treatment of electricity purchases. According to the preamble to the final rule, EPA stated as follows: (more…)
