California already has a Million Solar Systems plan in mind. See http://www.governor.ca.gov/state/govsite/gov_htmldisplay.jsp?sCatTitle=%20&sFilePath=/govsite/spotlight/august20_update.html.

Governor Schwarzenegger understands the benefits that solar energy can provide to our energy and economy -- while at the same time improving our economy.

The Spanish plan cited an example in which a solar thermal panel (probably to heat hot water for home use) is the technology that is being required. California's plan envisions a more comprehensive set of solar technologies, including photovoltaic and thermal.

The biggest solar challenge in California is keeping up with the explosive market growth in Germany and Japan.
