Jenya Meydbray writes a tribute to a well known and beloved member of the solar industry, Frédéric Dross.
California off to a strong clean electricity start with solar up 33.8%
Forty-eight days into 2025, CAISO gas use for electricity is down almost 28%, while battery use is up 78%, and solar has already met 100% of demand in the midst of winter.
States that adopt recent building energy efficiency codes save more energy
A report highlights the increasing benefits of building energy efficiency codes, and maps the states that are adopting them. Building energy efficiency is a key element of a least-cost 100% renewables grid, the National Renewable Energy Laboratory has found.
Record-breaking rates of solar connected to the power grid in 2024
A new report by the Business Council for Sustainable Energy and BloombergNEF unpacks the market and policy trends facing the U.S. solar industry.
Water-based recycling of perovskite solar cells
An international team has developed a new technique to recycle perovskite solar cells (PSC) made on glass substrates using a water-based solution. Tests showed that the recycled cells were as efficient and stable as the original devices.
Sunrise brief: Sunnova cuts about 15% of workforce
Also on the rise: Enhanced geothermal projects could scale greatly as costs decline. Invenergy CEO and spouse give $100 million to advance the energy transition. And more.
U.S. startup unveils ‘world’s largest’ transparent organic PV window

Enhanced geothermal projects could scale greatly as costs decline
A team of researchers and industry participants predict a significant near-term energy contribution from enhanced geothermal projects, saying in a journal article that the technology could provide “stable baseload and potentially dispatchable electricity.”
Who’s footing the bill for new transmission?
While the Federal Energy Regulatory Commission’s Order 1920 could provide a step forward, many regions continue to struggle with implementing effective cost-sharing frameworks.
Go with the flow (batteries)
There is a gap in the market for long-duration energy storage (LDES), according to US-based manufacturer ESS Inc. – one which can’t be plugged with lithium-ion chemistry. Hugh McDermott, of ESS Inc. tells pv magazine how he thinks iron flow batteries fit into the energy system of the future, as the company pursues global expansion.
