How To Power California With Wind, Water and Sun

Study shows how to power California with wind, water and sun : Imagine a smog-free Los Angeles, where electric cars ply silent freeways, solar panels blanket rooftops and power plants run on heat from beneath the earth, from howling winds and from the blazing desert sun. A new Stanford study finds that it is technically and economically feasible to convert California's all-purpose energy infrastructure to one powered by clean, renewable energy. Published in Energy, the plan shows the way to a sustainable, inexpensive and reliable energy supply in California that could create tens of thousands of jobs and save billions of dollars in pollution-related health costs. "If implemented, this plan will eliminate air pollution mortality and global warming emissions from California, stabilize prices and create jobs—there is little downside," said Mark Z. Jacobson, the study's lead author and a Stanford professor of civil and environmental engineering. He is also the director of Stanford's Atmosphere/Energy Program and a senior fellow with the Stanford Woods Institute for the Environment and the Precourt Institute for Energy. Jacobson's study outlines a plan to fulfill all of the Golden State's transportation, electric power, industry, and heating and cooling energy needs with renewable energy by 2050. It calculates the number of new devices and jobs created, land and ocean areas required, and policies needed for infrastructure changes. It also provides new estimates of air pollution mortality and morbidity impacts and costs based on multiple years of air quality data. The plan is analogous to one that Jacobson and other researchers developed for New York state. The study concludes that, while a wind, water and sunlight conversion may result in initial capital cost increases, such as the cost of building renewable energy power plants, these costs would be more than made up for over time by the elimination of fuel costs. The overall switch would reduce California's end-use power demand by about 44% and stabilize energy prices, since fuel costs would be zero, according to the study. It would also create a net gain, after fossil-fuel and nuclear energy job losses are accounted for, of about 220,000 manufacturing, installation and technology construction and operation jobs. On top of that, the state would reap net earnings from these jobs of about $12 billion annually. Read more ...
