On Monday, the U.S. Environmental Protection Agency (EPA) unveiled an historic proposal to cut carbon dioxide emissions from the nation's power plants to 30% below 2005 levels by 2030. The ambitious and flexible proposed regulations would see each state develop it's own plan to cut power sector carbon emissions using a variety of options, from improving power plant efficiency or capturing CO2 at smokestacks to "beyond the fence" measures to increase the use of clean energy, improve end-use energy efficiency, or even join or create interstate markets for carbon trading.

All week, experts at TheEnergyCollective.com have been reacting to and dissecting the EPA's new regulations. Today, I moderated a live videocast with Energy Collective experts and featured columnists Geoff Styles, Matthew Stepp (of The Capitol Energy Report) and John Miller (of Energy and Policy Developments). (Jim Pierobon of Game Changers also joined briefly but was disconnected due to technical difficulties).

We covered the hot topics and key questions that have surfaced about EPA regulations:

  • How does EPA establish CO2 reduction targets for each state?
  • What options do states have to comply with the EPA CO2 targets?
  • What legal challenges will the proposed rule face?
  • What impacts will the regulations have on the U.S. energy mix?
  • How might the new EPA regulations affect international negotiations over climate change?
  • Will the EPA rules drive new energy innovation?
