DC rooftop PV providing domestic hot water to residential building at 140 F
Domestic hot water, with a heating system powered exclusively by DC solar power, has now covered the needs of an apartment building in Linz, Austria, for a period of a year. The 14 residential units are each connected to their own 1.36 KW solar arrays.
Recent advances in fast EV charging
Researchers at Oak Ridge National Labs and University of Tennessee have developed a novel fast-charging battery anode material. Plus news updates from GM, Volvo and Shoals Technologies.
New York needs 20 GW of new renewables by 2030, plus transmission, says grid operator
Even adding 9.5 GW of renewables will increase transmission congestion, said NYISO, in a report that also called for development and commercialization of dispatchable emission-free resources.
8minute Solar Energy changes name, expands its vision

Grid operator MISO is making progress on renewables interconnection, says trade group leader
The Midwestern transmission operator MISO is moving to increase transmission and otherwise facilitate interconnection, said a regional trade group leader, yet she also recommended further improvements by MISO and neighboring grid operators.
Strategies to maximize clean energy development while being good land stewards
SEIA white paper lays out framework for engaging with communities and minimizing impacts of solar siting.
Nature Conservancy favors low-impact renewables deployment in the West
Deploying renewables in a high electrification scenario for the western U.S. in a way that avoids “the most sensitive natural areas and working lands” would cost “only 3%” more than a scenario without that constraint, found a study promoted by the land conservancy.
The mobility rEVolution: Zero-cobalt cathode for highly stable lithium-ion batteries
U.S. researchers say they have developed a way to make cobalt-free lithium-ion battery cathodes, while Ford says it has broken ground on a new $5.6 billion production complex for electric vehicles and batteries.
Solliance hits 30.1% efficiency on perovskite/silicon tandem solar cell
The Solliance consortium achieved a 29.2% record efficiency for the solar cell in November 2021, from just 28.7% in March 2020. In recent months, it increased the perovskite cell for the tandem device from 17.8% to 19.7%.
