California moves toward requiring 100 per cent clean power by 2045
CALIFORNIA lawmakers approved a measure mandating that all electricity come from wind, solar and other cleanenergy sources by 2045, marking the state’s biggest step yet in the fight against global warming.
The state Assembly voted 4332 in favour of the legislation on Tuesday. It would eliminate the reliance on fossil fuels to power homes, businesses and factories in the world’s fifth-largest economy, accelerating a shift already under way. The state currently gets about 44 per cent of its power from renewables and hydropower.
“It’s already happening for economic reasons,” said Pavel Molchanov, an analyst at Raymond James Financial Inc., who noted that solar and wind are the cheapest sources of electricity in some regions. “I think California can get to 100 per cent in 15 years.”
California has positioned itself to lead the battle against climate change by cutting emissions even as the Trump administration has worked to roll back the state’s stringent auto pollution standards and prop up ailing coal-fired power plants. Earlier this year, California became the first US state to mandate solar rooftop panels on almost all new homes. It would be the second state to require 100 per cent carbon-free power after Hawaii.
“This is landmark legislation that is helping to stave off some of the worst effects of climate change,” said Dan Jacobson, state director for Environment California, an environmental advocacy group. “We need it more than ever because the state and the world are starting to see the devastating impacts of climate change.” The move would accelerate a shift already under way to wind and solar but hinges on a big bet – that battery costs will plunge, allowing for a transition away from the natural gas plants that provide about a third of California’s electricity.
The bill must clear the state Senate before heading to Gov Jerry Brown, who is expected to sign it into law.
Proponents of the bill say solar and wind energy already compete in price with fossil fuels and that costs are expected to decline further. But they also note that the measure allows for a mix of clean- energy resources, including large hydroelectric dams.
