Water, solar power work together

Water, solar power work together - SignOnSanDiego.com: "Some of the biggest producers of solar power in San Diego County aren’t power companies, they’re water agencies.
That’s because they have a combination of lots of space — the tops of their huge water tanks -— and high energy usage.
Most of the systems actually are owned by companies that sell the power they produce to the districts at a discount from what they would pay San Diego Gas & Electric Co. The move to add solar is really a money-saving measure, water officials say."
