"The farm - called the Agua Caliente Solar Photovoltaic Facility — can produce 290 MW of solar electricity, which is enough to power 230,000 homes at peak capacity... The farm was built with a $967 million loan guarantee from the Department of Energy, as well as equity from owners NRG Energy and MidAmerican Solar, which is the energy-focused fund owned by Warren Buffett’s Berkshire Hathaway. MidAmerican bought 49 percent of the $1.8 billion farm in early 2012."
"More solar has been installed in the U.S. in the last 18 months than in the last 30 years,
and almost a third of new electricity came from solar last year."

"The large 200-foot by 400-foot field of solar panels next to the county’s engineering complex was completed last year and is generating serious energy savings.
... This array generates 70% of the electrical power required not only by the engineer’s office, but also the nearby traffic maintenance building and radio tower
.... The entire $1.8 million construction cost was funded through a $3 million grant from the U.S. Department of Energy."
