Two years ago, one of us (Jason) was at an energy industry conference planning committee and he made the point that whether or not everyone around the table agreed on global warming, the issue was just about to break out and dominate the public conversation on energy. Because of global warming, he went on to say, getting a new coal-fired power station built was just a "prudency review waiting to happen." For those of you that remember, it was, in many ways, the prudency review process that killed the nuclear industry back in the 1980s.
In the past several weeks, several announcements suggest that this situation has indeed come to pass. Here's what's going on: the Kansas Department of Health and Environment turned down a permit for 1400-MW of coal-fired power based on emissions of global warming gases. This is arguably the first time a coal plant has been denied for this reason. Let's repeat the state: Kansas. It's not California, Florida, New York,or Oregon. Kansas has historically been a coal-friendly state.
Another story revealed that even in Montana, a coal-producing state (or at least one with significant coal reserves), coal plant permits are being fought by bipartisan coalitions, and that electric utilities concede that these groups are effective. In other reports that cross our desks regularly, we note that more than 10,000 MW of coal plants recently have been canceled or postponed around the country.
No doubt many are of you are cheering! But there are trade-offs in all things -- especially in energy, environmental, and economic issues. As enthusiasm for coal wanes, it grows for nuclear, even among some that have fought tooth and nail against nuclear in the past. However, there's a problem. The fastest any nuclear plant can come online, given regulatory and financing hurdles, is around 2015. Meanwhile, electricity demand continues to grow. As much as the rewewables camp wants to believe it, solar and wind are not going to supply all or even most of the necessary power anytime soon. (We strongly believe in renewable energy, but also believe that we need energy storage to make it work on a scale that will be able to replace a significant amount of fossil fuels.) So what's going to replace coal as the dominant fuel for electricity production?
