Center for Sustainable Energy
Energy Loop
highlights our staff’s latest thinking on sustainable energy market development and policy efforts.


Jack Clark
Balancing government, industry and consumer needs

California has gained significant positive results with sustainable energy incentive programs with record numbers of consumers going solar and driving more electric vehicles. Some of what CSE has learned in helping to drive such clean energy initiatives can help local government agencies to shape successful clean energy programs throughout California and across the country.

Rebecca Feuerlicht
California is charging ahead with legislation and incentives

As California continues procuring more energy from solar photovoltaic (PV) systems, energy storage is increasingly seen as a critical element to help achieve the reality of sourcing 33% of the state’s energy and beyond from renewables. It’s a technology that is now scaled to meet the needs of medium and small businesses and provides several significant benefits.

Paul Hernandez
California continues to lead the transportation transition

We’re pleased this year’s California legislative session produced major activity across the transportation spectrum. It closed in September with a flurry of bills that advance cleaner, greener transportation, giving us hope that we can expect equally significant efforts in the 2015 legislative session.

Jeremy Del Real
Need to get sound energy advice, be targeted and plan long-term

While some school districts successfully secured Proposition 39 (California Clean Energy Jobs Act) funds for sustainable energy projects during the current solicitation period, the majority of California schools are struggling to identify resources to help them through the application process.

Sachu Constantine
Bill to Undermine Community Choice Aggregations Defeated

When it comes to sustainable energy, CSE is very much in favor of consumer choice, which is why we support Community Choice Aggregations (CCAs) that allow citizens in California cities and counties to combine their buying power to secure alternative energy supply contracts.

Jack Clark
Roadmap lays out path to clean energy for local jurisdictions

The idea of creating zero net energy (ZNE) homes and buildings is emerging as a realistic goal, for new construction and, to the extent possible, upgrading of existing building stock. While there are various definitions of ZNE, a broadly accepted meaning is a building or home that produces as much energy as it consumes over the course of a year.

Ria Langheim
Understanding homeowner perspectives

We're interested in better understanding the energy efficiency actions of homeowners who install rooftop solar electric systems and their perspectives on performing home energy upgrades. Insights into the connection between solar adoption and energy upgrades could help policymakers and regulators in designing future

Len Hering
In recent years, we’ve broadened our scope

Recently, we dropped the “California” from our name to become the Center for Sustainable Energy (CSE). It’s not because we are doing anything less in California, but instead it reflects the fact that we are doing work in other states – and plan on being even more engaged in clean energy not only statewide, but throughout the nation.

Join us to learn about a wide range of subjects related to energy efficiency, renewable energy and clean transportation. For a complete list, visit our Events page.
