EPA gets to set a standard for new. For the existing, EPA sets guidelines for what we think is appropriate, but then states develop plans that work for them, taking into consideration their specific energy mix.

When consumers do not take full advantage of efficiency gains, it is because they are weighing other factors that influence their decision making. When the federal government arbitrarily places one of those factors over others, it makes consumers worse off.

The EPA's greenhouse gas regulations, along with a host of other onerous regulations, are unnecessarily driving out conventional fuels as part of America's energy mix. The consequences are higher energy prices for families and a contraction of our nation's economic growth.

Greenhouse gas pollution, through its contribution to global climate change, presents a significant threat to Americans health and to the environment upon which our economy and security depends.

Transparency is all about letting in and embracing new ideas, new technology and new approaches. No individual, entity or agency, no matter how smart, how old, or how experienced, can afford to stop learning.

Any first-generation technology will. But we are looking at carbon the same way we look at every pollutant under the Clean Air Act; we look for the new technologies that are available. We recognize that these power plants are going to be around for decades.
