Stanford study shows how to power California with wind, water and sun
A Stanford study outlines how power from facilities such as the Ivanpah Solar Electric Generating System in California’s Mojave Desert can be part of the state’s renewable energy future.
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.
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.
According to the researchers’ calculations, one scenario suggests that all of California’s 2050 power demands could be met with a mix of sources, including:
- 25,000 onshore 5-megawatt wind turbines
- 1,200 100-megawatt concentrated solar plants
- 15 million 5-kilowatt residential rooftop photovoltaic systems
- 72 100-megawatt geothermal plants
- 5,000 0.75-megawatt wave devices
- 3,400 1-megawatt tidal turbines
The study states that if California switched to wind, water and sunlight for renewable energy, air pollution-related deaths would decline by about 12,500 annually and the state would save about $103 billion, or about 4.9 percent of the state’s 2012 gross domestic product, in related health costs every year. The study also estimates that resultant emissions decreases would reduce global climate change costs in 2050 – such as coastal erosion and extreme weather damage – by about $48 billion per year.
