Positive Impact of Choosing Solar Energy in Los Angeles California         

The recent heatwaves across some American states are a good indication of climate change which is grossly enhanced by the use of fossil fuel. Transitioning from fossil fuel to renewable energy might pose challenges but it is the only path to securing the future. With that in mind, the state of California is investing heavily in enormous solar projects.

With the emergence of solar farms across California, power plants such as Diablo Canyon nuclear reactor and other gas generators will be retiring in a few years from now. The California grid operator estimates that additional 2,000 megawatts are required to overcome the risk of a power outage during winter. California is taking the lead and we hope the rest of the country will follow.
