Renewables Surpass Coal in Both the U.S. and U.K. in Historic Firsts

April 2020 was the first month ever that renewables generated more electricity than thermal coal in the United States every single day, while across the Atlantic, the United Kingdom's rapid decarbonization of its electricity grid has achieved another significant milestone – completing a whole month (30 days) without coal power for the first time in 138 years.


Renewables Surpass Coal in U.S. Power Generation Every Day in April

April 2020 was the first month in U.S. history that renewables generated more electricity than coal on every day of the month. That's based on new data from the U.S. Energy Information Administration (EIA) and compiled by the nonprofit Institute for Energy Economics and Financial Analysis (IEEFA).

The daily consecutive run of renewables over coal began on March 25 and continued for 40 straight days through May 3. That breaks the previous record of just nine continuous days.

The strong output from utility-scale solar, wind, and hydropower is based on several factors, including low gas prices, warmer weather, new renewable capacity connecting to the grid late last year, and lower power demand because of the coronavirus.

IEEFA reported: "Coal's high cost has made it increasingly one of the last fuel choices for many utilities, a trend reflected by its declining market share for electric generation: just 15.3% in April, according to preliminary EIA figures.

"In January, coal's market share fell below 20% for the first time in many decades — and possibly for the first time in the entire history of the U.S. power industry — ending at 19.9%.

"EIA figures also show its share continued to erode, falling to 18.3% in February and 17.3% in March. As recently as 2008, coal's market share was above 50% in the months of January, February and March."

IEEFA had previously forecasted that power generation from renewables would likely surpass coal-fired generation in 2021, an important milestone in the energy transition that is well underway. But in the first quarter of 2020, renewable generation unexpectedly exceeded coal, and with this strong performance continuing in the second quarter, there is an increasing chance that the milestone could occur this year.

U.K. Goes a Month Without Coal Power for First Time for 138 Years

The United Kingdom's rapid decarbonization of its electricity grid has achieved another significant milestone – completing a whole month (30 days) without coal power for the first time in 138 years, reported The Institute for Energy Economics and Financial Analysis (IEEFA) this week.

The milestone was reached on Sunday 10 May (U.K.) time and celebrated by National Grid ESO, the organization that runs the grid and is responsible for keeping the lights on nationwide. It was the first time this occurred since coal power was first used on the U.K. power system in January, 1882, at Holborn Viaduct.

Within a few years, there will be no coal generation at all – with the remaining plants shuttered, and one or two converted to gas by 2025. National Grid aims to be able to operate a fully zero emission grid when weather conditions allow from 2025, and is accelerating its adoption of new technologies and management systems that will allow it to side line gas power plants when possible.

Just a few days before the new month-long coal-free milestone, National Grid released its latest end of year planning report outlining the main achievements it has made in the long path to a fully decarbonized grid before 2050.

"We're really proud of our zero carbon targets," National Grid wrote in a blog a few days earlier. "In May 2019 there was a 2-week period where there was coal free operation of Great Britain's electricity system. This has quickly been beaten after the record breaking sunlight in April."

It noted that the carbon intensity of the electricity system has halved over the last five years, and is down 60 per cent when compared to 2013. "The recent low demand for energy due to COVID-19 has dramatically reduced the use of fossil fuel based generation, and this has been supported by our optimized renewable generation," it says.

"And as supply changes, so to does demand, as renewables capacity and smart grid functionality increases further to enable the side-lining of gas power plants when possible."

For decades my tribe has been fighting to protect our forests from outsiders who want to log it or clear it for palm oil. For my people, the forest is our mother and our best friend. Everything we need to survive comes from the forest: food, medicines, building materials, and there are many sacred sites in the forest.

Overthinkers are people who are buried in their own obsessive thoughts. Imagine being in a large maze where each turn leads into an even deeper and knottier tangle of catastrophic, distressing events — that is what it feels like to them when they think about the issues that confront them.

A 4,000-year-old ice shelf in the Canadian Arctic has collapsed into the sea, leaving Canada without any fully intact ice shelves, Reuters reported. The Milne Ice Shelf lost more than 40 percent of its area in just two days at the end of July, said researchers who monitored its collapse.
