California aims for 100% carbon-free electricity by 2045, making it the largest economy committing to total renewables

California Governor Jerry Brown has signed legislation that moves the state towards 100% renewable energy within the next 27 years.

The bill specifically requires that 50% of California’s electricity is to come from clean energy sources, including wind, solar and other renewables, by 2025, and 60% by 2030.

Previously, California had mandated 50% renewable electricity by 2030.

Its design also moves the state away from power generated by fossil fuels which today represent half of its energy production, while renewables comprise about one-third of current generation.

The state follows the likes of Iceland, who now derives all of its energy for electricity and home heating from geothermal and hydroelectric power plants, alongside several US cities that have already attained 100% renewable energy supplies.

Although California is already considered one of the best nation’s for solar energy with thermal power plants and solar PV producing 24,324 GWh in 2017, the law creates a benchmark that further countries are expected to copy.
