Renewable Energy Farms Spread Through California Deserts NewsWeek, BY ELIJAH WOLFSON / NOVEMBER 24, 2014 “…….. , part of the interconnected swatches of desert land in California that, combined, make up the largest wilderness area in the Lower 48. It’s also about to become host to the biggest renewable-energy projects in the world.
Already, 13 of them are built or on the way. There’s the Desert Sunlight Solar Farm, under construction just east of Joshua Tree National Park; its solar photovoltaic cells will cover over 4,000 acres of public land administered by the federal Bureau of Land Management (BLM). When completed in 2015 (assuming things go as planned), it is expected to peak at a nominal power of 550 megawatts—making it the most powerful solar farm on the planet. There’s also the McCoy Solar Energy Project, in the middle of the Mojave. When it’s done, it will be even bigger and more powerful than Desert Sunlight, covering 7,700 acres of BLM land and 470 acres of private land, and with an electrical production capacity of 750 megawatts.
Then there are the wind farms. These produce less power than their solar brethren and take up much more space. The Ocotillo Wind Energy Facility, for example, covers 12,436 acres at the edge of the Anza-Borrego Desert State Park, near the border with Mexico, and produces 315 megawatts of power……..
And these new wind and solar farms—cities, call them, since they aren’t like any farm you’ve seen—are only going to multiply in the coming years. The need for clean energy is expected to increase dramatically in the next decade, particularly after the U.S. and China recently announced a historic agreement to lower greenhouse gas emissions in their respective countries. At the core of the pact are two sets of commitments: The U.S. will lower emissions 26 to 28 percent by 2025 from the initial 2005 baselines, while China has agreed to set an emissions peak for 2030 and then commit to lowering emissions……….
It’s cheaper to have a big mass—having power all come from one source,” says Elkin. “But the advantages of having a more distributed rooftop-type solar is that you can provide the power generation really close to being used. It’s more efficient.” He says we are probably headed toward a mix, with “microgrids” providing neighborhoods with access to small, local solar farms.
Until then, though, achieving emissions reductions at the scale of what has been agreed to between the U.S. and China “is not going to happen without some level of large-scale renewable-energy development,” says Helen O’Shea, director of the National Resources Defense Council’s Western Renewable Energy Project.
And Michael Gerrard, director of the Sabin Center for Climate Change Law at Columbia University, says that if conservationists keep fighting that, they will be missing the forest for the trees. “We are facing a mass extinction,” he says. “The only pathway to solve that problem involves a massive increase in renewable energy. Unfortunately, many new renewable-energy facilities have been slowed down or stopped because of their adverse effects on certain species. I think we can no longer have the luxury of doing that.”ttp://www.newsweek.com/renewable-energy-farms-populate-california-286644
