UK Wind Power Exceeds Coal During Storm, Continues to Break Energy Records
As the UK cleans up after being lashed by the remnants of Hurricane Bertha, which brought summer flooding and travel disruption, it is also reaping the benefits of a boost to the country’s wind industry brought by the storm, with output hitting near record highs.

Wind power met almost 16 percent of the UK’s power demand on Monday morning, and 13.1 percent of demand over the preceding 24 hours.
The strong performance meant wind power output exceeded coal power—which accounted for 11.3 percent, according to trade body EnergyUK.
It also took output to levels close to the record set during last December when wind energy met 10 percent of electricity demand throughout the month and peaked at 17 percent of demand.
The UK has broken a series of wind records over the past 12 months, and last week new government figures confirmed that 2013 had seen around 15 percent of electricity in the country come from renewables—7.9 percent of which was provided by onshore and offshore wind turbines.
The plentiful supply of wind energy is also helping to pick up the slack this week as French energy companies EDF was forced to shut down four nuclear reactors in the UK.
The reactors are expected to remain closed for eight weeks—after a fault was found in a boiler unit—but National Grid have said the closures should not affect the UK’s energy supply.
It told the Financial Times:
Demand is low at this time of year, and a lot of wind power is being generated right now.
This is an ironic turn of events, with critics of renewables arguing that surges in output caused by weather conditions create problems as renewable energy can not provide a reliable supply.
They argue such sources of energy will also fail to deliver the needed steep emissions reductions as back-up power capacity is still needed.
But the National Grid has said it can manage high levels of variable renewables, and this week’s events have shown that large reactors and generators can also suddenly go offline with no warning.
As recent government figures have show, in 2013 the load factors from onshore and offshore wind actually exceeded or equaled that of gas at nearly 28 percent.

On his first day in office President Joe Biden started signing executive orders to reverse Trump administration policies. One sweeping directive calls for stronger action to protect public health and the environment and hold polluters accountable, including those who "disproportionately harm communities of color and low-income communities."
Michael S. Regan, President Biden's nominee to lead the U.S. Environmental Protection Agency, grew up near a coal-burning power plant in North Carolina and has pledged to "enact an environmental justice framework that empowers people in all communities." NCDEQ

Clear-cutting a forest is relatively easy—just pick a tree and start chopping. But there are benefits to more sophisticated forest management. One technique—which involves repeatedly harvesting smaller trees every 30 or so years but leaving an upper story of larger trees for longer periods (60, 90, or 120 years)—ensures a steady supply of both firewood and construction timber.
A Pattern in the Rings<p>The <a href="https://www.encyclopedia.com/science/dictionaries-thesauruses-pictures-and-press-releases/coppice-standards-0" target="_blank">coppice-with-standards</a> management practice produces a two-story forest, said <a href="https://www.researchgate.net/profile/Bernhard_Muigg" target="_blank">Bernhard Muigg</a>, a dendrochronologist at the University of Freiburg in Germany. "You have an upper story of single trees that are allowed to grow for several understory generations."</p><p>That arrangement imprints a characteristic tree ring pattern in a forest's upper story trees (the "standards"): thick rings indicative of heavy growth, which show up at regular intervals as the surrounding smaller trees are cut down. "The trees are growing faster," said Muigg. "You can really see it with your naked eye."</p><p>Muigg and his collaborators characterized that <a href="https://ltrr.arizona.edu/about/treerings" target="_blank">dendrochronological pattern</a> in 161 oak trees growing in central Germany, one of the few remaining sites in Europe with actively managed coppice-with-standards forests. They found up to nine cycles of heavy growth in the trees, the oldest of which was planted in 1761. The researchers then turned to a historical data set — more than 2,000 oak <a href="https://eos.org/articles/podcast-discovering-europes-history-through-its-timbers" target="_blank" rel="noopener noreferrer">timbers from buildings and archaeological sites</a> in Germany and France dating from between 300 and 2015 — to look for a similar pattern.</p>
A Gap of 500 Years<p>The team found wood with the characteristic coppice-with-standards tree ring pattern dating to as early as the 6th century. That was a surprise, Muigg and his colleagues concluded, because the first mention of this forest management practice in historical documents occurred only roughly 500 years later, in the 13th century.</p><p>It's probable that forest management practices were not well documented prior to the High Middle Ages (1000–1250), the researchers suggested. "Forests are mainly mentioned in the context of royal hunting interests or donations," said Muigg. Dendrochronological studies are particularly important because they can reveal information not captured by a sparse historical record, he added.</p><p>These results were <a href="https://www.nature.com/articles/s41598-020-78933-8" target="_blank">published in December in <em>Scientific Reports</em></a>.</p><p>"It's nice to see the longevity and the history of coppice-with-standards," said <a href="https://www.teagasc.ie/contact/staff-directory/s/ian-short/" target="_blank">Ian Short</a>, a forestry researcher at Teagasc, the Agriculture and Food Development Authority in Ireland, not involved in the research. This technique is valuable because it promotes conservation and habitat biodiversity, Short said. "In the next 10 or 20 years, I think we'll see more coppice-with-standards coming back into production."</p><p>In the future, Muigg and his collaborators hope to analyze a larger sample of historic timbers to trace how the coppice-with-standards practice spread throughout Europe. It will be interesting to understand where this technique originated and how it propagated, said Muigg, and there are plenty of old pieces of wood waiting to be analyzed. "There [are] tons of dendrochronological data."</p><p><em><a href="mailto:email@example.com" target="_blank" rel="noopener noreferrer">Katherine Kornei</a> is a freelance science journalist covering Earth and space science.

Earth's ice is melting 57 percent faster than in the 1990s and the world has lost more than 28 trillion tons of ice since 1994, research published Monday in The Cryosphere shows.
