Rooftop wind energy innovation claims 50% more energy than solar at same cost
BASF is currently testing Aeromine Technologies’ patented motionless wind-harvesting system.
Prospects for US solar electricity at $0/kWh
A new Credit Suisse report suggests that from 2025 through 2032, the United States could see solar and wind power purchase agreements regularly signed for under $0.01/kWh, due to a combination of manufacturing and project tax credits.
IEA-PVPS expects polysilicon prices to stabilize by end of 2023
The International Energy Agency Photovoltaic Power Systems Programme (IEA-PVPS) recently published a report on trends in PV applications for the 2021-22 period. Prices for polysilicon, wafers, cells and modules rose, while production capacity expanded in China and beyond.
The weekend read: Central Asian solar on the rise
Utility-scale solar is stirring in the region, with support from development banks. Following a series of competitive auctions, PV projects have been commissioned and are under development in Uzbekistan and Kazakhstan. In the latter nation, corporate interest in distributed, small-scale renewables is growing but for further market uptake, additional incentives should be introduced, practitioners say.
