Transportation<br />

In 2005, Californians purchased one-quarter of the hybrids on<br />

the market. Currently 1.2% of total vehicle sales in the nation<br />

are hybrids. National sales of hybrids have generally doubled<br />

every year since 2000. Other alternatives, such as biodiesel,<br />

ethanol and hydrogen are gaining ground, but still represent<br />

only a tiny fraction of our fuel portfolio. Hydrogen fuel cells<br />

are still prohibitively expensive and we don’t yet have the ability<br />

to produce and distribute large quantities of ethanol and<br />

biodiesel. Improved battery performances are giving a boost to<br />

plug-in hybrids, which can operate for 20 miles solely on electricity.<br />

The technology relies on an existing distribution system-the<br />

electrical grid-but must overcome concerns about<br />

power plant emissions. At least two auto manufacturers,<br />

Toyota and Honda, have said they plan to offer flexible-fuel<br />

plug-in hybrids soon<br />

Two-Pronged Approach: Reduce Emissions<br />

and Increase Commute Alternatives<br />

If CARB’s greenhouse gas reduction rule is upheld, the state<br />

would be able to stabilize its greenhouse gas emissions by<br />

2010. That would be a significant achievement. But if<br />

California is to avoid the devastating impacts of global warming,<br />

we will need to reduce our emissions even further. Plus,<br />

swapping petroleum-guzzling cars to alternative fuel vehicles<br />

will do nothing to address our very real congestion problems,<br />

particularly in job centers such as <strong>Silicon</strong> <strong>Valley</strong>.<br />

We need a two-pronged approach: we need to reduce our<br />

tailpipe emissions and decrease the number of miles we drive,<br />

particularly solo. We need to increase our use of transit, carpooling,<br />

telecommuting, walking and biking.<br />
