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.
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.
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.
Under this grant, the Washoe Tribe of Nevada and California will install seven ground-mounted solar photovoltaic (PV) arrays throughout its three communities in Nevada, covering approximately two acres cumulatively.
Under this grant, the Soboba Band of Luiseño Indians plans to install the Soboba Community Solar Energy Project, a 1.0-megawatt (MW) AC ground-mounted photovoltaic (PV) system that, once installed, will generate approximately 1,884,686 kilowatt-hours (kWh)/year, meeting 80% of the annual energy needs of key community facilities.
Under this grant, the Pala Band of Mission Indians plan on building a 94.8-kilowatt (kW) DC solar system on its fire station. The system will use a combination of rooftop PV and ground-mounted panels that will be installed on land adjacent to the Pala Indian Reservation’s fire station.
The 10th Annual Native American Economic Development Conference is hosting renewable energy sessions, including Tribal Renewable Energy Projects Roundtable: Creating Sovereignty, Energy Independence, Economic Diversification and Sustainability.
