Renewable electricity powered California 100% for the first time in history
Renewable electricity met 100% of California’s demand for the first time on Saturday, environmentalists said, much of it from large amounts of solar power produced along Interstate 10, an hour east of the Coachella Valley.

Electricity is a secondary energy source: it is generated through the conversion of primary energy sources such as natural gas, coal, solar, hydropower, and wind. Electricity’s versatility is not cost-free: a substantial amount of energy is lost in its generation and the cost of storage is high, compared with fuels such as coal, oil and natural gas. The economics of battery technology hold the key to expanded use of renewable sources to generate electricity.

Declining costs and government encouragement have resulted in a rapid increase in solar energy production in the United States over the past 10 years, although solar’s share remains small: 1.6 percent of all electricity generation in 2018. That rapid growth is projected to continue.
