By Lorraine Chow Transitioning the world to 100 percent renewable electricity isn’t just some environmentalist pipe dream—it’s “feasible at every hour throughout the year” and is more cost-effective than the current system, which largely relies on fossil fuels and nuclear energy, a new study claims. The research, compiled by Finland’s Lappeenranta University of Technology (LUT) […]
By Alex Kirby If you think a world powered by 100 percent renewable electricity—and significantly cheaper than today’s—is an impossible dream, there’s a surprise in store for you. A new study says it’s already in the making. A global transition to 100 percent renewable electricity, far from being a long-term vision, is happening now, the […]
Tesla is sending its Powerwall system to Puerto Rico as the island deals with widespread power loss in the wake of Hurricane Maria. According to Electrek, the company has been quietly shipping hundreds of battery packs to be paired with solar panels to Puerto Rico ever since the storm cleared. Fortune reported that Tesla employees […]
By Paul Brown India and the U.S. would both benefit financially by phasing out coal-fired electricity production and investing in renewables. Although the two countries are at completely different stages of development, they have both been seen as among the most problematical in matching their needs for electricity with the global attempt to avoid dangerous […]
Despite the Koch brothers’ best efforts, it looks like gas guzzlers are on the way out. Sales of electric vehicles will surpass those using internal combustion engines by 2038, a new analysis has found. Bloomberg New Energy Finance (BNEF) projects that “electric cars will outsell fossil-fuel powered vehicles within two decades as battery prices plunge, […]
Tesla has been awarded a contract to install the world’s largest lithium ion battery. Under the agreement, the company will build the system within 100 days or else it’s free—a promise CEO Elon Musk famously made in March to help solve South Australia’s energy woes. The billionaire entrepreneur spoke about the technology to reporters in […]
A tiny, scenic island lying off Scotland’s west coast is truly a model for sustainable, off-grid living. With no mainland electricity connection, the Isle of Eigg gets its electricity from the water, the wind and the sun. After decades of using diesel generators, in February 2008 the residents of Eigg officially switched to their own […]
The answer to powering our devices might have been hiding in our sushi all along. An international team of researchers has used seaweed to create a material that can enhance the performance of superconductors, lithium-ion batteries and fuel cells. The team, from the U.S., the UK, China and Belgium, came up with the idea to […]
One of the most common pitfalls of solar energy is storing it. On sunny days there is typically an excess of energy, which is lost if not captured. But, fortunately many battery storage options are now available, including this groundbreaking new electrode prototype from the RMIT University in Melbourne, Australia, which could store energy at […]
