Combating global warming is an enormous and nebulous task, but a few good folks over at Energista have decided to enlighten the rest of us on how we could achieve the Kyoto targets of 1990 carbon emissions in the United States by 2025, almost entirely through the electric sector. Energy efficiency gets the largest chunk, but nuclear, cleaner coal and renewable generation also contribute a substantial portion (there's a nifty chart showing how each technology could help).
The most challenging strategy might be the use of carbon capture and sequestration (CCS) - grabbing the CO2 from emissions and storing it underground - which is theoretically possible, but to date practically infeasible. The problem isn't getting the carbon, it's figuring out how and where store it (my vote is for Yucca Mountain...)
Overall, scientists suggest that a reduction in emissions of 80% is going to be required to stabilize the climate, and that might take even more action than suggested here. However, it's a good start and is achievable by 2025.
