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 />
