As much as one-third of the carbon in sugar is lost as carbon dioxide (CO2) during fermentation processes that use biomass to make renewable diesel and sustainable aviation fuel (SAF). That waste CO2 translates into notable consequences for biorefiners scrambling to meet demand for low-carbon biofuels. Less carbon makes it into the fuel, lowering yields. More […]

In simulations and experiments, researchers demonstrate that introducing tiny nanoscale texturing on the surfaces of materials in perovskite/silicon tandem solar cells can significantly increase efficiency by reducing the amount of light energy that is lost due to reflection. A new nanotextured design can achieve a power conversion efficiency potential above 29%, which simulations suggest could […]

The Battle Born Solar Project in Nevada – what would have been the largest solar farm in the US – is now canceled because nearby residents said it would be an eyesore. Huge Nevada solar is canceled The 850 megawatt, 9,200-acre solar farm, which would have been constructed in southern Nevada’s Moapa Valley, was to […]

Leading automakers have signalled their intention to scrap internal combustion engines by 2030 or cut back sharply on their production as the sector turns towards electric vehicles. The latest to unveil plans was German group Daimler, maker of Mercedes Benz and smart cars, which aims to be fully electric before 2030—five years ahead of a deadline […]

Electric cars—key to reducing emissions and meeting climate change goals—have boosted their market share in Europe, data showed Friday, as the region prepares to abandon petrol and diesel. Battery electric vehicles more than doubled their share of new car sales in Europe in the second quarter, according to the European Automobile Manufacturers’ Association (ACEA) which […]

The push to transition from carbon-emitting fuel sources to renewable energy is hitting a roadblock in Nevada, where solar power developers are abandoning plans to build what would have been the United States’ largest array of solar panels in the desert north of Las Vegas. “Battle Born Solar Project” developers this week withdrew their application […]

The future of Samoa’s electricity system could go green, a University of Otago study has shown. Pacific Island nations are particularly susceptible to climate change and face high costs and energy security issues from imported fossil fuels. For these reasons many Pacific Island nations have developed ambitious 100 per cent renewable energy targets. However, they […]

Designing future low-carbon energy systems to use power generated in excess of the grid’s demands to produce hydrogen fuel could substantially lower electricity costs, according to new work published by Advances in Applied Energy by Carnegie’s Tyler Ruggles and Ken Caldeira. Renewable energy sources like the Sun and wind have natural variation due to weather […]

The photovoltaic effect of ferroelectric crystals can be increased by a factor of 1,000 if three different materials are arranged periodically in a lattice. This has been revealed in a study by researchers at Martin Luther University Halle-Wittenberg (MLU). They achieved this by creating crystalline layers of barium titanate, strontium titanate and calcium titanate which […]

With the looming threat of climate change, it is high time we embrace renewable energy sources on a larger scale. Photovoltaic systems, which generate electricity from the nearly limitless supply of sunlight energy, are one of the most promising ways of generating clean energy. However, integrating photovoltaic systems into existing power grids is not a […]
