About 650 meters beneath the Latrobe Valley, the heart of Victoria’s coal country, lies a little-known, naturally hot 65℃ pool of water in an enormous aquifer. This aquifer is a source of geothermal energy—a renewable source of heat or electricity that is, so far, being used to heat an aquatic center in the town of […]

The controversial Scarborough gas project off Western Australia will cause a substantial rise in greenhouse gas emissions at a time when the world must rapidly decarbonise, new analysis released today shows. The A$16 billion plan by Woodside Petroleum has been described as Australia’s biggest new fossil fuel investment in nearly a decade. The report, produced by […]

The expansion of renewable energies is placing increasing demands on the power grids. and in the process requires forecasts that are as precise as possible as to how much solar power will be fed into the grid. In addition to clouds, aerosol particles also strongly influence the amount of electricity generated by photovoltaic systems. Current […]

Japan’s Green Growth Strategy signals a commitment to net-zero greenhouse gas emissions by 2050—and hydrogen produced from renewable energy can play an important role in this shift. A team of researchers from Harvard University, Shandong University, China University of Petroleum Beijing and Huazhong University of Science and Technology have explored the possibility of producing hydrogen […]

Growth in renewable energy is set to hit an all-time record this year, but is still falling “well short” of what is necessary to reach net zero emissions by 2050, the International Energy Agency said on Wednesday. New renewable power capacity is forecast to reach 290 gigawatts (GW) by the end of 2021, surpassing last […]

Researchers at Northern Illinois University and the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) in Golden, Colorado, are reporting a potential breakthrough that could help speed commercialization of highly promising perovskite solar cells (PSCs) for use in solar panels. In an Oct. 28 brief communication to the journal Nature Sustainability, the scientists […]

Alternative-energy research at Oregon State University is charting a path toward the mass adoption of clean cars powered by direct-ethanol fuel cells. Zhenxing Feng of the OSU College of Engineering helped lead the development of a catalyst that solves three key problems long associated with DEFC, as the cells are known: low efficiency, the cost […]

As part of the EU-funded REACH project, Dutch start-up Kitepower has successfully deployed its Airborne Wind Energy System (AWES) in the Caribbean. This is a landmark achievement for the company working to bring its Falcon 100kW to market. It will provide plentiful, inexpensive renewable energy to remote communities and small power grids. The AWES Falcon […]

Billions of solar panels globally will soon come to the end of their lives, but when they get thrown away essential materials that are needed to make future panels are being wasted. It is estimated that there will be 78 million tonnes of total waste by 2050. This is roughly 4 billion panels. But these […]

Electrical grids are almost always over-dimensioned to meet short surges in energy demand. Put simply, power stations need to have an excess number of generators only to be able to provide electricity during peak hours. This mismatch between power supply and demand and the inefficient operation of power stations lead to higher carbon dioxide (CO2) […]
