These Water Treatment Plants Won't Go to Waste With Sun Power



Increasingly, solar and water mix nicely.

Here in the sun-rich San Joaquin Valley, cities are looking at solar as a way to cut power bills at energy-sucking wastewater treatment plants. Tulare and Madera have them, as does Parlier, while officials in Atwater are on tap, so to speak. It would be the city's biggest-ever endeavor, but one that could save millions of dollars in years to come.

We've written about the proliferation of solar in and around water sources. Check out this blog from May.

It makes sense. Water is heavy, and wastewater plants, which are among the largest energy users in most cities, have lots of space atop and near their water tanks. In fact, Greentech solar asks in this article, "Are wastewater plants the new frontier for muni solar?"

(And maybe not just for solar. Here's a story about Bill and Melinda Gates financing technology that would convert converting organic waste sludge into biodiesel and methane.)

Maybe wastewater plants are just ONE frontier for the world's most renewable resource. Rooftop solar projects could abound across the country. Research into solar roads is under way, and some places are installing solar-powered street lights. Read about streetlight projects in Missouri and Florida here and here.

What does all this mean for the San Joaquin Valley? The possibilities are eye popping. The Valley's $20 billion agriculture industry is starting to embrace renewable energy, including solar.
The Valley already has dozens of proposed solar projects waiting in the wings, and cash-strapped cities and businesses are looking for ways to slash their power bills, especially during the my-shoes-are-melting-into-the-pavement summer heat extremes.

Meanwhile, solar energy prices are dropping, and coming close to parity. In a few years, the sun could be shining even brighter on the Valley's solar industry.
