These before and after photos of Lake Oroville in Northern California show the dramatic results of extended years of drought. Funding support from the Energy Department to California’s Appliance Efficiency Program is lowering flow rates for faucets and showerheads as well as helping the state maintain a nearly constant level of electricity consumption per capita despite population growth.
EERE Success Story—Energy Department Assists with Conserving Water in California

Energy and water are strongly interdependent in the U.S. economy. Electricity generation requires water, and water treatment and distribution require energy. The Energy Department has studied this water-energy nexus and it has funded state initiatives promoting both water and energy conservation.

EERE Success Story - Back to the Basics: Studying Solar Cell Components

As any athlete will tell you, going back to the basics when practicing a sport can provide a refreshed perspective on skills that will improve overall performance. One SunShot Initiative awardee found the same principle can be applied to the science behind the decades-old practice of attaching metal contacts to solar cells.

EERE Success Story—Energy Efficient Windows to Reach Market Quicker with New Tool

About 10% of the energy used in U.S. buildings—approximately 4 quads per year—compensates for energy lost through windows. To address this inefficiency, architects, engineers, and home-builders are advocating the use of high-performance windows, which are composed of insulated glass units (IGUs). IGUs lessen unwanted heat gain by combining insulating frames and multiple panes, thin film coatings, and special gas fills between the panes, while selecting for other properties, such as transmittance of visible light and solar heat gain.
