For the first time ever, the latest edition of the Tracking the Sun report is publicly sharing the data used in the report analysis, which is a win-win for both solar companies and solar customers.

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.

Healthcare accounts for 9% of the energy used in U.S. commercial buildings, and lighting represents the largest electricity use in all of healthcare. But as scientists learn more about light’s nonvisual effects—such as the role it’s known to play in suppressing the release of melatonin, a hormone that helps control the sleep-wake cycle—it’s becoming increasingly clear that light-emitting diode (LED) healthcare lighting offers an opportunity to address more than just visual needs.

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.

The numbers are in and the verdict is clear: clean energy is on the rise, both at home and around the world.

Is it possible to increase your vehicle’s performance and fuel efficiency while also slowing climate change through reduced greenhouse gas emissions? New research says yes.

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 Daylight Savings Time ending on Sunday, try these 5 energy-saving tips to help you save money on your utility bills.

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.

The commercial and civic benefits of drones are growing—from surveying the eye of a hurricane to helping farmers maintain healthy crops—enabling researchers to imagine new possibilities for the emerging technology. Now, researchers think drones can help the solar industry.  

Over the last 40 years, the Energy Department's Weatherization Assistance Program has helped weatherize more than 7 million homes, helping to improve the health and safety of occupants while reducing energy bills. Another benefit of this program is job creation with a recent national evaluation of the program finding that it supports 8,500 jobs in a typical year.

Since the DOE Lab-Corps program launched in fall 2015, Idaho National Laboratory (INL) has put through more researchers than any other national lab. We sat down with INL Director Mark Peters to find out why he thinks researchers at INL are so attracted to the innovative Lab-Corps curriculum.

The Energy Department is joining weatherization organizations across the U.S. who've used federal government funding to weatherize low-income homes in celebrating National Weatherization Day on Sunday, October 30. Forty years after the Energy Department started this program, it’s making a bigger impact than ever so many Americans don’t have to choose between heat, medicine, and food.

You might think it would take a Halloween trick to transform grasses, corn husks, and other plants and organic waste into fuel you can use to power your car or an airplane. But scientists are already figuring out how to use chemical processes at a biorefinery to cost-effectively convert the sugars from non-food plants and wastes into biofuel. Biofuels are already powering some airplanes—and that’s no trick!

The Pacific Northwest National Laboratory has worked with Whooshh Innovations on an inventive project demonstrating a fish-friendly transport system. This Energy Department-funded technology uses lengths of flexible tube and slight differences in pressure to gently propel salmon and other fish up and around obstacles such as hydroelectric dams in waterways.

The Energy Department’s Weatherization Assistance Program (WAP) has reduced energy costs for millions of low-income households by providing energy efficiency upgrades. Many of the people getting their homes weatherized are also realizing another positive result: improved health and home safety.

The beautiful island of Kauai, Hawaii, is known for its pristine beaches and dramatic mountain ranges. But Kauai is not just a vacation spot; it is also the location of one of the largest algae biofuel production facilities in the United States.

Millions of Americans looking to buy a home have a new resource to help them go solar in the process. Thanks to a partnership between SunShot Initiative awardee Sun Number and real estate company Zillow, homeowners and prospective buyers across the country can now quickly and easily access detailed information about a property’s solar energy potential.

Remote Alaska Communities Energy Efficiency Competition helps communities implement energy solutions that can be replicated throughout rural Alaska and potentially other Arctic regions.

The Energy Department’s SunShot Initiative is taking new steps to reduce solar energy costs. Social sciences research is helping to explore the forces behind solar adoption in the United States.
