As the classic phrase goes, “You got to start somewhere.” 

This is never more true when it comes to California. They often lead the United States in creating new policies that are then adopted by the rest of the country. “As goes California, so goes the United States” is another popular phrase. 

Therefore it's exciting to learn that California has been experimenting with the use of 100% clean energy to power the entire state – primarily from solar power but it's also using wind, hydropower and geothermal. It might last for 15 minutes or for the entire day depending on the demand, but it's certainly setting the stage for a prolonged stretch where clean and renewable energy fully replace fossil fuels. 

It's a start, but again, you've got to start somewhere.
