As the solar-energy industry gears up to add more generating capacity than any other source this year, a Pew Research Center survey, “Public Opinion on Renewables and Other Energy Sources,” finds that almost nine out of 10 U.S.
According to research from the Cockrell School of Engineering at the University of Texas, Austin, homes with solar panels do not require on-site storage to reap the economic and environmental benefits of solar energy.
A digital marketplace is changing the way electricity is produced, traded and consumed in Australia. Two pilot programs, each including about 5,000 households, will allow homeowners with solar panels and batteries to trade electricity in a digital marketplace—the first such network in the world.
In January, the United States Department of Energy (DOE) announced that several of its Energy Efficiency and Renewable Energy (EERE) supported technologies won awards in R&D Magazine’s R&D 100 Awards, which the DOE called the “Oscars of Innovation.” A number of these technologies concern ele
President Trump’s Campaign pledge to bring jobs back to coal mines could be holding former coal workers back from another energy sector that is booming and predicted to maintain a strong growth curve for at least another decade. That sector is wind generation.
Microgrids are a huge topic in the renewable-energy world. Local energy grids with control capability—meaning they can disconnect from the traditional grid and operate autonomously—are becoming more attractive for a variety of applications as solar and battery costs plummet.
A large offshore wind turbine being tested in Denmark set a record of 9 megawatts (MW) of power on Dec. 1, 2016. The V164 turbine produced almost 216,000 kilowatt-hours (kWh) in 24 hours, enough to power approximately 7,200 homes in the United States for an entire day.
While President Trump campaigned on a promise to boost opportunities for fossil fuels and revitalize the coal industry, market forces might already have limited his opportunities for fulfilling that pledge.
On Feb. 7, The Solar Foundation released the National Solar Jobs Census 2016, an annual report on solar employment in the United States. Despite the energy source’s relatively small role on the national landscape, the solar workforce saw considerable, dramatic growth last year.
While wind and solar power have been leading the charge in renewable energy growth, other renewable industries have struggled to contribute on the same scale. Offshore wind, for example, has lagged far behind the success of its onshore cousin.
Powering entire countries (especially smaller ones) without fossil fuels is possible. In 2016, Costa Rica’s electrical grid mainly used renewable energy, the Costa Rican Electricity Institute (ICE) stated in a Jan. 3 press release. The country went 271 days using only renewable-energy production.
Energy Storage is a major challenge for the renewable-energy industry. With sufficient storage, when the sun isn’t shining or wind isn’t blowing, intermittent power generation wouldn’t be such an issue.
A report released jointly in October by the Corporate Eco Forum (CEF) and the World Wildlife Fund shows that leadership in the corporate world may now be fully engaged in the push for more renewable-energy generation.
It’s hard to predict precisely what electrical contractors will face in 2017, because many things will influence the landscape where they work. However, there’s every reason to believe that new and emerging technology in a changing digital world should bring opportunity and optimism.
A report published in December 2016, "Achieving Urban Resilience: Washington DC," documents how the District of Columbia could save $5 billion over 40 years with smart surface technologies, such as cool roofs, green roofs, solar PV, bioretention, rainwater harvesting, reflective pavements, permeable
