Here in Alameda we have our own city owned utility, Alameda Power and Telecom, that provides a relatively clean mix of power. Other parts of California, including our immediate neighbours here in the SF bay area, don’t do so well.

The table below shows the projected 2008 mixes for PG&E and Alameda, alongside the 2007 mix for the whole state. As you can see, Alameda Power & Telecom is doing a pretty good job of using renewables (79% total when you include the large hydroelectric mix), whereas PG&E, one of the largest electricity utilities in the state, is still reliant on natural gas and nuclear power.

It would be nice to see solar playing a larger part in that mix too. Perhaps over the next few years, as some of the larger solar power station projects come on line, that number will increase for both companies.

Energy Resources Alameda P&T PG & E 2007 CA Average
Eligible Renewable 55% 14% 10%
- Biomass & waste 8% 4% < 1%
- Geothermal 38% 4% 2%
- Small hydroelectric 4% 14% 6%
- Solar < 1% < 1% 0%
- Wind 6% 2% 2%
Coal 10% 2% 32%
Large Hydroelectric 24% 17% 24%
Natural Gas 10% 44% 31%
Nuclear 1% 22% 3%
Other < 1% 1% 0%
TOTAL 100% 100% 100%

How does your local utility do when it comes to the use of renewable energy sources?
