Southern Power Co. and esVolta LP have entered partnership to develop four utility-scale energy storage projects in California. The total scale of these projects is set at 86MW (345MWh). Southern Power is a wholesale electricity supplier and a subsidiary of Southern Company, a utility provider headquartered in the state of Georgia. esVolta specializes in energy storage solutions based on lithium-ion batteries and designed for grid support services. ...  more

With the PV power division of Tesla remaining in the doldrums, Elon Musk, the CEO of Tesla, has promised to ramp up the total output of the company's solar rooftop panels, dubbed "solar roof," to 1,000 sets on a weekly basis by the end of 2019. ...  more

Although Earth is known as the water planet, about 97.5% of the Earth's water is seawater, which people cannot drink. If the large amount of seawater can be converted into fresh water, collecting water resources wouldn't be difficult. Recently, Australian scientists have brought in a new high-efficiency solar steam generation system that claims to remove nearly 100% of salt and provide clean water to off-shore areas of the countryside. ...  more

U.S. scientists are currently developing a brand new type of PV cell, dubbed thermophotovoltaics cell (STPV), which can power drones for several days of flight. This is a far cry from the existing battery-powered drone models which have a cruising ability of less than 30 minutes. ...  more

China’s PV cell manufacturer GS-Solar has signed a cooperation agreement with Shanxi Coal International Energy Group (here referred as Shanxi Coal) to build a 10GW production base for double-sided heterojunction (HDT) cells. GS-Solar has been a leader in the development of the heterojunction technologies that allow for PV cells with higher conversion efficiency rates. ...  more

Do you ever imagine that the subsidy of renewable energy might be related to social inequality? According to a recent study from Portland State University (PSU) in the US, in some countries, the increase of fossil fuel tax might worsen the costs of people's electricity or fuel, leading to more energy poverty. ...  more

A joint research team from Tianjin University and Tsinghua University has recently produced a lithium anode featuring air stability and water proof features; the lithium anode can significantly boost the energy density and specific energy of lithium-ion batteries, which makes it a better option than graphite anode. ...  more
