Over a period of about six months, the United States suffered two extreme weather events that had the same outcome: widespread energy disruptions through rolling power outages that left people dangerously vulnerable to the elements.
Last August, a powerful heat wave knocked out electricity for millions of Californians in what was the first statewide set of power outages in some 20 years. This past February, a brutal and deadly cold snap in Texas caused rolling blackouts, leaving millions of Texans without the usual means to stay warm. ....

Don't blame wind for Texas blackouts


Don t blame wind for Texas blackouts

It is erroneous to claim that renewable power was largely responsible for the grid problems in Texas.
The Texas grid operator, Electric Reliability Council of Texas, has documented that considerably more gigawatts of fossil fuel and nuclear sources were lost than renewables. While wind power outperformed forecasts across the state, natural gas did the opposite, with nearly twice the amount of natural gas going offline than was predicted under ERCOT’s extreme generator outage scenario.
ERCOT’s senior director of systems operations called offline wind turbines “the least significant factor” in the blackouts, according to Bloomberg, with frozen instruments at natural gas, coal and nuclear facilities playing a more important role, along with reduced supplies of natural gas. Those who persist in blaming wind might also consider t ....

No 'green halo' for renewables: First Solar, Veolia, others tackle wind and solar environmental impacts

Renewables are vaunted for their ability to reduce greenhouse gas emissions as part of the push to address climate change in the United States and elsewhere, but that doesn’t mean they have zero environmental impact. 
Projections from the Energy Information Administration (EIA) show the share of renewable generation increasing from 18% in 2018 to to 31% in the U.S. by 2050. As their capacity grows, so does the scale of their effects along with industry and public awareness of the challenges.
Some of the environmental issues getting the most scrutiny have been toxic substances and wastewater generated in the production of some solar photovoltaic (PV) cells; changed land use and disrupted wildlife habitat from both solar and wind projects; and significant recycling and disposal challenges for both solar panels and wind turbine rotor blades. ....
