It’s simple: relying on oil, coal, and natural gas for the bulk of our energy needs is ultimately a losing proposition. Fossil fuels will peak and run out someday; they’re already becoming less efficient and even more environmentally harmful to extract. In the meantime, burning them emits so many pollutants and causes so many other problems (global warming, air pollution, water pollution, devastation at extraction sites, destruction of habitat, oil spills, etc.) that we need to diversify our sources of energy as soon as possible.

There are a wide variety of alternative and renewable sources of energy (solar, wind, biofuels, geothermal, hydroelectric, etc.). The main challenges are to make renewables cost-effective and to minimize unintended consequences (such as solar vs. desert habitat; windfarms vs. birds, hydro power vs. river wildlife, and biofuels vs. food production). Solving these problems calls for a major investment into green jobs, including training a workforce for these jobs (see Green Jobs). In any case, weaning ourselves off fossil fuels will help avoid massive societal disruptions and will have major benefits for our air quality, our water quality, and reducing emissions that contribute to global warming.

Examples of actions that help encourage the use of renewable energy: Established in 2002 under SB 1078 and accelerated in 2006 under SB 107, California's Renewables Portfolio Standard (RPS) is one of the most ambitious renewable energy standards in the country. The RPS program requires electric corporations to increase procurement from eligible renewable energy resources by at least 1% of their retail sales annually, until they reach 20% by 2010. Governor Schwarzenegger has also stated publicly that meeting a 33% RPS by 2020 one of his administration's policy goals.

Example of actions that lead to less renewable energy: Despite proclamations (and a recent executive order) in support of a 33% RPS by 2020, Governor Schwarzenegger recently vetoed two bills, SB 14 (Simitian) and AB 64 (Krekorian), which would have established the 33% target as state law. In addition, budget stimulus packages have invested too heavily in highway projects (and other subsidies for fossil fuel based industries) and not enough in public transit, green jobs, or research and development of new, viable sources of renewable power.
