The Oil Drum: Europe | Gore sets goal of 100% carbon-free electricity by 2020 - 0 views

Al Gore has made a major speech in Washington this morning, setting out an ambitious goal for the USA to produce all of its electricity from carbon-free sources by 2020. I thought I'd comment on the technical feasibility of the plan, and the underlying economics of such an endeavour.

The short answer is: while 100% is probably unrealistic, it's not unreasonable to expect to be able to get pretty close to that number (say, in the 50-90% range) in that timeframe, and it is very likely that it makes a LOT of sense economically.
