Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

EETD Team Wins for Sprinkler App at BERC Cleanweb Hackathon

April 22, 2014

At the second annual BERC Cleanweb Hackathon, a Berkeley Lab Environmental Energy Technologies Division team consisting of Anna Liao, Daniel Olsen, and Andrew Weber, along with Robert Sadler from InTech Energy, took the top prize for best app by developing an intelligent residential irrigation system based on open source hardware. The app processes weekly weather, drought, and sunrise time data to set optimal watering schedules for automated sprinkler systems.

Each sprinkler 'client' is controlled by a server that handles all data processing and control decisions. The same signal can control an unlimited number of sprinkler 'clients.' The system developed by the team is projected to save between 3,000 and 6,000 gallons of water annually per residence depending on the type of system replaced and lawn/garden size.

The Cleanweb Hackathon, organized by the Berkeley Energy & Resources Collaborative encourages teams to build software-based business solutions and open-source code by introducing talented hackers at the University of California, Berkeley, to today’s energy and resource challenges.
