In joining CleanPowerSF, San Francisco’s community choice aggregation program, to power buildings at its headquarters, Salesforce hopes to set an example for other local businesses while helping San Francisco meet its renewable energy goals.

Legislation introduced in the U.S. Senate aims to move community solar forward nationwide. The bill would make permanent a U.S. Department of Energy program that promotes community solar, as well as boosting community solar in low-income communities and encouraging federal government participation in community solar.

The new sign-ups represent a surge of support that took place in just three months. The cities and counties will be enrolled in community choice aggregator Marin Clean Energy’s “Deep Green” option, which offers 100% wind and solar power produced in California.

With purchases planned to exceed Washington State’s RPS levels, Microsoft joins the trend of large technology companies buying clean energy on the open market.

The new regulation, the first of its kind outside of California, mandates 2.75 kW of solar for every 1000 square feet on new homes, as well as those that increase their square footage by 75% or more.

The power company says it aims to better understand the siting, installation, and operational requirements of commercial and industrial energy storage systems.
