Not only does Portland General Electric sell more energy from renewable sources to residential customers than any other utility in the US, our Governor Ted Kulongoski is calling for the state government to use only electricity from new renewable sources by 2010.

"New renewable sources" appears to not include hydropower. This is good because hydropower dams dramatically change the ecosystem of the waterway they are built on. It does appear to concentrate on wind and solar:

Wind and solar sources are attractive "because there's no fuel -- nature is the fuel -- you have very stable prices over the long term," said Rachel Shimshak, director of the Renewable Northwest Project, a nonprofit advocacy group.

Other renewable sources mentioned: geothermal and plant matter biomass.
