About $14 billion in tax credits for energy efficiency, clean coal, nuclear, renewables, etc. over 10 years Loan Guarantees for new technologies that reduce GHG and air pollution - $67.5 billion available $2 billion in standby support coverage for regulatory delay for 6 new nuclear power plants
Energy Independence and Security Act of 2007
Renewable Fuels Mandate - 36 billion gallons of biofuels annually by 2022—about 20% of projected gasoline usage Vehicle Fuel Economy Mandate - 35 miles per gallon by 2020 Lighting Mandate - Phase out inefficient (e.g., incandescent) bulbs by 2014 Appliance Mandates Federal Facility Requirements - Reduce energy consumption 30 percent by 2015 & new federal buildings must be carbon-neutral by 2030
Energy Improvement & Extension Act of 2008
$18 billion in tax credits - Extends many EPAct2005 tax credits
Farm Bill
Significant portion of proposed $50 billion Farm Bill Conservation Programs for terrestrial sequestration
States
RPS in over 26 states 24 states undertaking regulation
Net U.S. GHG emissions in 2006 down 3% since 2000. Net GHG emissions in 2008 will be lower than in 2000.

Projected Energy-Related CO2 Emissions over Time Show Steady Progress in Slowing Emissions Growth Projected energy-related CO2 emissions have steadily decreased since 2002.The EIA AEO 2009 projection of energy-related CO2 emissions in 2020 is nearly 1.7 gigatons CO2 below the comparable level in the AEO 2002. Projected cumulative emissions avoided from 2009 - 2020 total about 15 gigatons CO2.

Climate Change Technology: Meeting the Long-Term Global Challenge To reconcile the desire for global emission reductions and to provide the energy for continued economic growth and development, we will have to develop cost-effective technologies that transform the way we produce and use energy.

Reductions in Global Emissions Needed to Meet Range of Possible Goals Cumulative global emissions reductions ranging from about 1,100 to 3,700 gigatons of CO2 equivalent would be need over the course of the century to meet a range of atmospheric concentration goals (450 to 750 ppm).

How Big is One Gigaton1 of CO2? Today’s Technology
Actions that Provide 1 Gigaton / Year of Mitigation
Coal-Fired Power Plants
Build 320 “zero-emission” 500-MW coal-fired power plants in lieu of coal-fired plants without CO2 capture and storage (73% CF)—the equivalent of nearly half U.S. coal-fired nameplate generating capacity
Geologic Sequestration
Construct the equivalent of 1,000 sequestration sites like Norway’s Sliepner project (1.0 MtCO2/year)
Nuclear
Build 130 new nuclear power plants, each 1 GW in size (in lieu of new coal-fired power plants without CO2 capture and storage) (90% CF)
Electricity from Landfill Gas Projects
Install 7,700 “typical” landfill gas electricity projects (typical size being 3 MW projects at nonregulated landfills) that collect landfill methane emissions and use them as fuel for electric generation
Efficiency
Deploy 290 million new cars at 40 miles per gallon (mpg) instead of new cars at 20 mpg (12,000 miles per year)
Wind Energy
Install 170,000 wind turbines (1.5 MW each, operating at 0.45 capacity factor) in lieu of coalfired power plants without CO2 capture and storage
Solar Photovoltaics
Install 1.7 million acres of solar photovoltaics to supplant coal-fired power plants without CO2 capture and storage (10% cell DC eff’cy; 1700 kWh/m2 solar radiance; 90% DC-AC conv. eff’cy).
Biomass fuels from plantations
Convert to biomass crop production a barren area about 5.4 times the total land area of Iowa (about 200 million acres)
CO2 Storage in New Forest.
Convert to new forest a barren area about 2.5 times the total land area of the State of Washington (over 100 million acres) (Assumes Douglas Fir on Pacific Coast)

Percentage of Global Electricity Production from Low- or Zero-Emissions Technologies Across Scenarios by 2050 All three CCSP report models assume sufficient technological options—fossil power plants with CCS, nuclear power, and renewable energy—to allow for substantial reductions in global carbon emissions from electricity production. In all of the Level 1(≈450ppm CO2) stabilization scenarios, the electricity sector undergoes significant decarbonization by 2050 (see circles) and is essentially fully decarbonized by 2100.
