Using only existing technology and making no assumption or adjustment for the passage of federal carbon legislation and related price setting, the Synapse report for the Civil Society Institute develops a scenario for 2010 - 2050 that would provide the following benefits.
• Aggressive investments in more efficient technologies in every sector could reduce electricity use by 15 percent from today's requirements, or over 40 percent from a "business as usual" scenario. Utilities in several states are already achieving savings at this level.
• The U.S. could feasibly retire the entire fleet of coal-fired plants and build no new coal-fired generation, rather than burning more coal. Tens of billions could be saved in avoided pollution control costs at the coal-fired plants retired between 2010 and 2020. At the same time, we could retire 28 percent of the nation's nuclear capacity.
• Electric sector emissions of carbon dioxide fall by 82 percent relative to predicted 2010 levels. Emissions of SO2, NOx, and mercury fall in the BAU Case, as new emission controls are installed at coal-fired plants, but they fall much more in the Transition Scenario. Emissions of NOx fall by 60 percent over the study period, and emissions of SO2 fall by 97 percent. Electric sector mercury emissions are virtually eliminated.
• Renewable energy, including wind, solar, geothermal and biomass, would increase throughout the nation, eventually providing half of the nation's electricity requirements. Natural gas use in the electric sector would grow more slowly than under business as usual, leaving more gas for clean cars and other uses.
• There would be modest near-term costs of the scenario, but over the long term it would cost less than a business as usual energy future. The scenario would cost an estimated $10 billion per year more than the BAU in 2020, but it would save $5 billion annually by 2040 and $13 billion annually by 2050. These are direct costs only; they do not include savings resulting from reduced CO2 emissions or public health costs. (A recent National Academies study estimated the annual health impacts of power generation in the U.S. at $62 billion in 2005.) For a typical residential consumer, purchasing about 900 kWh per month, the 2020 cost increase would amount to about $2.20 per month. By 2040, the same customer would be saving about $1.50 per month and by 2050, saving nearly $4.00 per month.
