U.C. Berkeley study shows that a 90% clean US power grid by 2035 is not only feasible, but cheaper

Julian Spector / Greentech »

By using updated cost figures for wind, solar and batteries, the researchers found that it will be economically feasible to power a reliable grid by 2035, while only depending on natural gas for 10 percent of annual electricity production.

“Previous studies concluded either we need to wait until 2050 to decarbonize, or the bills will go up if you decarbonize,” said co-author Amol Phadke on a call with reporters. “I think we really need to revisit these conclusions because of the dramatic decline in costs.”

Super-efficient solar-powered catalyst boosts hopes for hydrogen fuel

After decades of research, scientists have managed to separate hydrogen from water with near perfect efficiency using a light-activated catalyst. Chemist Kazunari Domen and his colleagues fine-tuned the prototype system so that almost no energy from the absorbed photons is wasted — throwing open the door to producing clean, green hydrogen fuel from renewable solar energy.

Electric vehicle charging predicted to become zero-emission and off-grid

IDTechEx »

Off-grid, zero-emission charging is starting to take two basic forms. First is ZE microgrids that are off-grid or capable of being islanded (using the grid as backup called “fringe-of-grid”) that charge vehicles – eventually $15 billion in yearly sales on IDTechEx analysis. Second is land and marine vehicles and aircraft progressing to being energy-independent pure-electric vehicles EIEV, another large emerging market. Delightfully, they help each other. For example, cars getting much of their electricity from the new solar bodywork are easier to charge using affordable solar charging stations. »

New York Governor announced details for 21 large-scale renewable energy projects

New York News Release »

Governor Andrew M. Cuomo today unveiled the details of the awards for 21 large-scale solar, wind, and energy storage projects across upstate New York, totaling 1,278 megawatts of new renewable capacity. These projects, which New York Energy Research and Development Authority and other State and local agencies will ensure are sited and developed responsibly, will spur over $2.5 billion in direct, private investments toward their development, construction and operation and create over 2,000 short-term and long-term jobs. The awards accelerate New York’s progress towards Governor Cuomo’s Green New Deal goal to obtain 70 percent of the state’s electricity from renewable sources by 2030, as codified by the Climate Leadership and Community Protection Act, and supports the State mandate for a 100 percent carbon-free electricity sector by 2040.
