The energy systems that power our lives also produce wasted heat—like heat that radiates off hot water pipes in buildings and exhaust pipes on vehicles. A new flexible thermoelectric generator can wrap around pipes and other hot surfaces and convert wasted heat into electricity more efficiently than previously possible, according... Read more

NIMS and Softbank Corp. have developed a lithium-air battery with an energy density over 500Wh/kg—significantly higher than that of current lithium ion batteries. The research team then confirmed that this battery can be charged and discharged at room temperature. In addition, the team found that the battery developed by the... Read more

Perovskites are hybrid compounds made from metal halides and organic constituents. They show great potential in a range of applications, e.g. LED lights, lasers, and photodetectors, but their major contribution is in solar cells, where they are poised to overtake the market from their silicon counterparts....

The US government announced Wednesday it will auction more than 480,000 acres off the coasts of New York and New Jersey to build wind farms as part of its campaign to supply renewable energy to more than 10 million homes by 2030.... Read more

A new biologically inspired battery membrane has enabled a battery with five times the capacity of the industry-standard lithium ion design to run for the thousand-plus cycles needed to power an electric car.... Read more

For electric vehicles (EVs) to become mainstream, they need cost-effective, safer, longer-lasting batteries that won't explode during use or harm the environment. Researchers at the Georgia Institute of Technology may have found a promising alternative to conventional lithium-ion batteries made from a common material: rubber.... Read more

The European Union will need to invest 500 billion euros ($568 billion) in new generation nuclear power stations from now until 2050, the bloc's internal market commissioner said in an interview published at the weekend.... Read more

With the long-term goal to realize carbon neutrality, lithium batteries have acquired a growingly central role in the development of human society. The accurate yet efficient prognosis of battery state of health (SOH) remains vital in ensuring a safe and reliable operation. In addition, as the demand to increase battery... Read more

Lithium metal batteries could store much more charge in a given space than today's lithium-ion batteries, and the race is on to develop them for next-gen electric vehicles, electronics and other uses.... Read more

Homeowners know that the type of windows in a house contribute greatly to heating and cooling efficiency. And that's a big deal—maintaining indoor temperatures consumes great amounts of energy and accounts for 20 to 40 percent of the national energy budgets in developed countries.... Read more

A portfolio of 44 battery storage systems across San Diego County aimed at adding more emissions-free energy to California's electric grid is about to roll out, with one location in Chula Vista and another in El Cajon poised to break ground within the next month.... Read more

Researchers at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University may have found a way to revitalize rechargeable lithium batteries, potentially boosting the range of electric vehicles and battery life in next-gen electronic devices.... Read more

As New Zealanders plan their summer holiday trips, it's worth considering different travel options and their respective cost, both to the budget and the environment.... Read more

Officials with the Danish energy company Ørsted have announced that they have achieved first power on the Hornsea 2 project—a new windfarm off the coast of England in the North Sea. As part of their announcement, posted on the company's web page, officials noted that once the windfarm is fully... Read more

Researchers have developed a method to stabilize a promising material known as perovskite for cheap solar cells, without compromising its near-perfect performance.... Read more
