Americans used more renewable energy in 2016 compared to the previous year, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory. Overall, energy consumption was nearly flat.

Each year, the Laboratory releases energy flow charts that illustrate the nation's consumption and use of energy. Americans used 0.1 quads (quadrillion BTU), more in 2016 than in 2015. A BTU, or British Thermal Unit, is a unit of measurement for energy; 3,400 BTUs is equivalent to about 1 kilowatt-hour.

In their study published in Lithosphere this week, James Kessler and colleagues examine the geology of a scientific borehole drilled into the Snake River Plain, Idaho, USA, to investigate the potential for geothermal energy at depth. The site discussed in this paper is on the Mountain Home Air Force Base, where a drillhole in 1984 indicated that geothermal fluids were present at about 1.8 km depth.

As the cost of clean technology continues to fall, the world added record levels of renewable energy capacity in 2016, at an investment level 23 per cent lower than the previous year, according to new research published today by UN Environment, the Frankfurt School-UNEP Collaborating Centre, and Bloomberg New Energy Finance.

Global Trends in Renewable Energy Investment 2017 finds that wind, solar, biomass and waste-to-energy, geothermal, small hydro and marine sources added 138.5 gigawatts to global power capacity in 2016, up 8 per cent from the 127.5 gigawatts added the year before. The added generating capacity roughly equals that of the world's 16 largest existing power producing facilities combined.

The Nile River is under assault on two fronts – a massive dam under construction upstream in Ethiopia and rising sea levels leading to saltwater intrusion downstream. These dual threats now jeopardize the future of a river that is the lifeblood for millions.

Potentially explosive methane gas leaking from energy wells may travel extensively through groundwater and pose a safety risk, according to a new study by University of Guelph researchers.

Graphene-oxide membranes have attracted considerable attention as promising candidates for new filtration technologies. Now the much sought-after development of making membranes capable of sieving common salts has been achieved.

Inspired by an American fern, researchers have developed a groundbreaking prototype that could be the answer to the storage challenge still holding solar back as a total energy solution.

The new type of electrode created by RMIT University researchers could boost the capacity of existing integrable storage technologies by 3000 per cent.

Researchers at Ghent University have developed a process that turns grass into fuel.

Scientists at the Centre for Microbial Ecology and Technology (CMET), Ghent University have developed a way to turn grass into biofuel. Will we soon drive on ‘grassoline’?

"Until now, grass has mainly served as feed for animals. We can get more out of grass: due to its vast abundance, it is an attractive source to produce organics such as aviation fuel" , scientist Way Cern Khor tells us. During his PhD research at Ghent University, Belgium, he investigated methods that disintegrate and bioconvert grass until it can be used as a fuel.

The UK is placing energy storage at the heart of its new Modern Industrial Strategy, due to its potential to support smart energy systems and the automotive sector. As the energy industry moves away from carbon-heavy production, the twin-approach of renewable energy and storage will be critical for delivering on the demand while securing the future of UK energy.

Officials are celebrating the installation of the world's largest containerized vanadium flow battery storage system by capacity, which uses electrolyte chemistry developed at the Department of Energy's Pacific Northwest National Laboratory.
