The speakers covered various strategies to reduce carbon dioxide emissions, and though they are in the business of selling electricity, they all addressed technologies to prevent the neeed to build more power plants (or at least reduce the urgency to build). Mr. Sterba suggested the following actions:
> Increase the efficiency of appliances and lighting to reduce annual demand growth from the current 1.5% to 1%. This step alone would reduce CO2 emissions 9% by 2030.
> Build 50 GW of wind farms and solar power plants by 2020, and an additional 2 GW/year thereafter.
> Add 24 GW of nuclear capacity by 2020, and another 4 GW/year thereafter.
> Target raising the efficiency of new coal-fired plants to 46% by 2020 and to 49% by 2030.
> Make 90% of the new coal plants carbon capture–ready by 2020.
> Strive to have electric cars constitute 10% of all U.S. vehicles by 2017, and 30% by 2027.
> Increase distributed generation's share of U.S. installed capacity from
less than 0.1% today to 5% by 2030.
1. Efficient vehicles - Increase fuel economy for 2 billion cars from 30 to 60 mpg
2. Reduced use of vehicles - Decrease car travel for 2 billion 30-mpg cars from
10,000 to 5000 miles per year
3. Efficient buildings - Cut carbon emissions by one-fourth in buildings
and appliances projected for 2054
4. Efficient base load coal plants - Produce twice today’s coal power output at 60%
instead of 40% efficiency (compared with 32% today)
