Researchers from the United States and Brazil have developed a new device that can reduce energy losses in buildings by measuring and assessing the energy performance of windows without removing them from their site.
Funding support from the Energy Department's State Energy Program is being used by some states to retrofit water treatment facilities and wastewater systems to use less energy because these facilities can be responsible for as much as 35% of municipal energy use.
The U.S. Department of Energy Solar Decathlon competition now spans five continents — North America, South America, Europe, Africa and Asia — bringing together collegiate teams from around the world to address some of the most pressing global energy issues of our time.
In 2014, the Energy Department’s Geothermal Technologies Office introduced its mineral recovery research and development program to identify methods of recovering lithium and rare earth elements found in geothermal fluids. This year the effort expanded to include evaluation of comparable methods in other industries and the potential to translate successful methodologies for use in geothermal mineral recovery.
Building energy infrastructure that keeps wildlife safe is a key concern at the U.S. Department of Energy, which is why we have funded six teams to improve technologies that will protect eagles sharing airspace with wind turbines.
With Energy Department support, French Development Enterprises, LLC, GEI Consultants, and Oldcastle Precast announced the successful construction of the first prototype of a “French Dam.”The prototype technology uses modular design—a term for structures that use multiple standardized components that integrate easily— to significantly cut construction time and cost.
Overall utility-scale photovoltaic (PV) generated enough electricity last year to power more than 2 million homes. It’s also creating jobs – a lot of them. In 2015, the solar workforce grew at a rate 12 times faster than the overall economy and boasts a workforce of more than 200,000 domestic jobs.
Most island communities do not have economies of scale or local fossil fuel resources, two key factors contributing to significant increases in energy costs relative to mainland peers. A case in point is two islands located off the coast of Maine—Isle au Haut and Monhegan, both of which are currently weighing their energy futures.
Right now, biofuels and consumer products made from biomass are not commercially widespread. However, the Energy Department’s Bioenergy Technologies Office (BETO) is funding research and development to help lower their costs so that private industry can produce and sell them on the commercial market.
The Thanksgiving holiday is wonderful for getting together with friends and family but not very good for energy conservation because it contributes to an annual increase in energy use due to lights staying on longer, and appliances operating more frequently. Here are some energy saving tips to lower the unwelcome tradition of higher energy bills following Thanksgiving.
The Energy Department has updated Best Practice Guidelines for Residential PACE Financing Programs, which allow qualifying homeowners in states offering PACE financing to make energy upgrades with no upfront costs and repay the costs over time through a special property tax bill assessment.
Solar power is now more affordable in the United States than at any other point in history, and new analysis shows it has the potential to gain popularity in low- and moderate-income communities across the country.
The Home Energy Score, which evaluates energy in a home similar to miles per gallon reports fuel efficiency in vehicles, has now issued more than 50,000 scores nationwide as part of the Energy Department's continued efforts to help Americans save energy and money.
Since 2014, passionate college students from across the country have learned the ins and outs of the wind industry by participating in the Energy Department’s Collegiate Wind Competition, which challenges undergraduates to design and build a wind turbine and develop a business plan to market their project.
Beneath our feet lies a source of geothermal heat that can be tapped to provide heating and cooling to both residential and commercial buildings, manufacturing processes, greenhouses and aquaculture ponds.
Big box retailers are leading in commercial solar installations in the United States, but solar’s energy-saving benefits aren’t limited to Fortune 500 companies. Hospitals, small businesses, shopping malls, multi-family and other commercial and industrial properties have a new tool to help them go solar: the PACE Lease®.
De-Meter Power first developed the new financial tool through the SunShot Initiative Technology to Market program, which helps entrepreneurs bring innovative, early-stage technologies to the market.
China is one of the United States' critical partners in the global effort of addressing climate change. Last month, Assistant Secretary for Energy Efficiency and Renewable Energy David Friedman saw up close how the world’s two largest economies – and the two largest emitters – are committed to leading the world in transitioning to a low-carbon economy.
With fuel cell cars hitting the roads now, the need for places to fuel them is becoming a critical challenge. That‘s why, in addition to supporting hydrogen station technology R&D, the Energy Department launched the H2 Refuel H-Prize in October 2014. This competition challenges American innovators to develop small-scale hydrogen generation and refueling systems. These systems could support the growing retail infrastructure by providing ways to fuel hydrogen vehicles at people’s homes, community centers, or businesses.
As Hawaii charges toward its goal of 100% renewable electricity by 2045, the Energy Department's Energy Transition Initiative has been working with technical experts from the National Renewable Energy Laboratory to deliver training to Hawaii Public Utilities Commission staff to help them prepare for the coming changes.
