California farmers are planting solar panels as water supplies dry up

Can't grow crops, so we grow electricity.
Jon Reiter banked the four-seat Cessna aircraft hard to the right, angling to get a better look at the solar panels glinting in the afternoon sun far below.

The silvery panels looked like an interloper amid a patchwork landscape of lush almond groves, barren brown dirt and saltbush scrub, framed by the blue-green strip of the California Aqueduct bringing water from the north. Reiter, a renewable energy developer and farmer, built these solar panels and is working to add a lot more to the San Joaquin Valley landscape.

“The next project is going to be 100 megawatts. It’s going to be five times this size,” Reiter said.

Solar energy projects could replace some of the jobs and tax revenues that may be lost as constrained water supplies force California’s agriculture industry to scale back. In the San Joaquin Valley alone, farmers may need to take more than half a million acres out of production to comply with the Sustainable Groundwater Management Act, which will ultimately put restrictions on pumping.

Converting farmland to solar farms also could be critical to meeting California’s climate change targets. That’s according to a new report from the Nature Conservancy, an environmental nonprofit.

Working with the consulting firm Energy and Environmental Economics, the conservancy tried to figure out how California could satisfy its appetite for clean energy without destroying ecologically sensitive lands across the American West. The report lays out possible answers to one of the big questions facing renewable energy: Which areas should be dedicated to solar panels and wind turbines, and which areas should be protected for the sake of wildlife, outdoor recreation, farming and grazing?

One takeaway from the report, released this week: California will need hundreds or maybe thousands of square miles of solar power production in the coming decades — and it would make sense to build one-third to one-half of that solar capacity on agricultural lands, mostly within the state.

In part, that’s because the Central Valley is more ecologically degraded than California’s inland deserts, where bighorn sheep, desert tortoises and golden eagles still roam across vast stretches of largely intact wilderness. The San Joaquin Valley is home to two dozen threatened and endangered species, but the landscape was almost totally reshaped by agriculture long ago.

California has plenty of farmland that could be converted to solar panels without harming the state’s $50-billion agriculture industry, clean energy advocates say. A previous report identified 470,000 acres of “least-conflict” lands in the San Joaquin Valley, where salty soil, poor drainage or otherwise less-than-ideal farming conditions could make solar an attractive alternative for landowners.

At least 13,000 acres of solar farms have already been built in the valley, according to Erica Brand, director of the Nature Conservancy’s California energy program and a co-author of the newly released “Power of Place” report.

“It’s a region with tremendous opportunity to advance multi-benefit solar projects,” Brand said.

Very rich soil, but as CA grows there is more and competition for water between agriculture in the Central Valley and cities there that want to build more housing. Building more solar is great but we still need to store it as there is increased demand for air conditioning as the planet gets hotter and demands will go up at night. More challenges for the engineers and scientists.

What's neat is the land beneath the panels can rest for a decade or so 'till the panels croak. Then the rain will dissolve all those salts left over from agrabiz, percolating it down into the aquifer--which may or may not pose its own problem. However, if the concentration is too high, it can be filtered by high pressure pumping through certain ceramic membranes. Non optimal, but non fatal I say. After the panels die, they either can be replaced, or the land can be planted, but using regenerative agricultural practices this time.

As alternative energy sources become more plentiful and cheaper, desalination technology will have to grow. Yup, CA has always had years of plenty and years of drought but water will become more and more critical.
