Here are a couple of updates on teams competing in this year's Solar Decathlon in Denver in October.
It’s turning out to be a great year for minor metals. Rechargeable-battery ingredient cobalt has gained 83 percent, while ruthenium, used in the chemical industry and electronics, is up 63 percent. The latest star is vanadium, an obscure silvery-grey metal thought to have been used to harden steel as far back as the Crusades.
Supporters of geothermal electricity generation development around the world are pushing for more sharing of knowledge and lessons learned as the key to building out the significant untapped geothermal resources in regions like Central America.
An Australian company is introducing its own version of bitcoin that will let homeowners and businesses sell excess energy generated from their rooftop solar panels to neighbors, without a middleman taking a cut.
A four-story office building powered by a combination of thermal and PV solar and wind energy in South Australia has cut its connection to the electricity grid in what its owners claim to be a world first.
Twenty years ago, the problem with rooftop solar was that customers needed a large collection of lead acid batteries to store their daytime energy and use this energy at night. But simple net metering rules made it possible for the electric grid to function as a 100 percent efficient storage device.
Details were released yesterday for the South Australia government’s call for more projects that can contribute to making renewable energy generation on demand and that will provide energy storage in the state.
Canadian utility TransAlta is retrofitting wind turbines at it Melancthon wind farm in Ontario with integrated condition monitoring systems (CMS).
China’s creating the world’s largest power company. The government of President Xi Jinping approved the merger of Shenhua Group Corp., the country’s top coal miner, with China Guodian Corp., among its largest power generators, the State-owned Assets Supervision and Administration Commission said Monday.
Delaware Gov. John Carney today authorized the creation of an Offshore Wind Working Group (OWWG) to advance offshore wind for the state.
The Department of Energy last week released its long-awaited grid-reliability study, after months of work at the agency to respond to Secretary Perry’s directive calling for the report. The tone and content of Perry’s April 14th memo suggested to many that the study would inevitably produce a set of findings that coal-fired power plants could take to the bank as proof that they need help from the federal government to stay in operation.
Most of the lithium used to make the lithium-ion batteries that power modern electronics comes from Australia and Chile. But Stanford scientists say there are large deposits in sources right here in America: supervolcanoes.
Vancouver, B.C.-based Dajin Resources Corp. last week signed a memorandum of understanding with Reno, Nev.-based Geothermal Development Associates to share geothermal data to support their separate operational goals in Nevada.
London-based investment firm Bioenergy Infrastructure Group (BIG) last week purchased 20 biomass and waste-to-energy facilities from the U.K. Green Investment Bank.
We want to hear your innovation story. We will recognize the most innovative power projects with the Power-Gen International Projects of the Year Awards in Las Vegas in December.
Grid operators and traders thought they were totally prepped for the historic U.S. solar eclipse. There was just this one thing they didn’t completely factor in: “irregular human-behavior patterns.”
The U.S. Department of Energy’s National Renewable Energy Laboratory and Clean Energy Group (CEG) have released the first comprehensive public analysis detailing the potential size of the commercial behind-the-meter battery storage market in the United States.
Sunrun yesterday said it has reached an agreement with Comcast for the solar and storage company to be the exclusive solar provider for Comcast Cable.
