For loyal readers who look to the raw data, here [pdf] are the proposed EPA regulations on greenhouse gas emissions from power plants.
Nationwide, by 2030, this rule would achieve CO2 emission
reductions from the power sector of approximately 30 percent
from CO2 emission levels in 2005. This goal is achievable because
innovations in the production, distribution and use of
electricity are already making the power sector more efficient
and sustainable while maintaining an affordable, reliable and
diverse energy mix.
