Solar energy capacity in California at the end of last year, up from less than 1 gigawatt in 2007. Solar has gotten so ubiquitous in the state that the source is accounting for major chunks of the power generated in its grid system. [The Independent]
The source, The Independent, reports that California sun produces so much power that electricity prices turn negative. ‘In March, during the hours of 8am to 2pm, system average hourly prices were frequently at or below $0 per megawatt-hour.’
That’s what Arizona’s energy picture should look like.
