California has always taken pride in being on the cutting edge of technology but in the case of solar, it may be catching up with some of its south-western peers in the United States. The Terra satellite used the on-board ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) imaging system to take these pictures of two solar farms in California. On the left is First Solar’s Desert Sunlight solar generation facility that has recently come on board. It is expected to generate 550 MW of electricity from Riverside County. On the right is the the Topaz solar farm in San Luis Obispo County generating a similar amount of electricity.
