The Californian State Assembly will vote on a bill next week on whether or not to shift to 100% clean energy by 2045.

A number of Californian politicians and community leaders have signed a letter backing the move as stakeholders across the state call for people to get behind the plans.

“Transitioning California away from fossil fuels to clean and renewable sources of electricity will make our cities and our state stronger, healthier, and more resilient. Expanding California’s commitment to clean energy through Senate Bill 100 will create jobs and new business opportunities while helping our state become a more equitable society where everyone has opportunity in a thriving local economy,” the letter from leaders – including the San Jose Mayor Sam Liccardo and several San Diego City Councillors – reads.

Michael Brune, Executive Director of the Sierra Club – America’s leading environmental organisation, is calling on everyone to lend their support by lobbying decision-makers and asking them to back what he insists will be “the most powerful thing our state can do to fight climate change”.
