Signed on September 27, 2006 Goal: reduce California GHG emissions to 1990
levels by 2020: 427 MM tons of CO2 California Air Resources Board (CARB) is
leading the effort Executive Order S-3-05 proposed to reduce the
GHG emissions to 20% of 1990 by 2050 Means by 2020:

Renewable Portfolio Standards
28 states have RPS
*Four states, Illinois, Missouri, Virginia, and Vermont, have set voluntary goals for adopting renewable energy instead of portfolio standards with binding targets.

Renewable Energy: the Time is now
“The use of vegetables oils for engine fuels may seem insignificant today but such oils may become in the course of the time as important as the petroleum and the coal tar products of the present time”
“The fuel of the future is going to come from fruit like sumac out by the road, or from apples, weeds, sawdust-almost everything”
“I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that”
Rudolph Diesel 1912
Henry Ford 1925
Thomas Edison 1931
Our Nation will then have a major conservation effort, important initiatives to develop solar power, realistic pricing based on the true value of oil, strong incentives for the production of coal and other fossil fuels in the United States, and our Nation's most massive peacetime investment in the development of synthetic fuels. Jimmy Carter “State of the Union” 1980
