The Global Wind Energy Council (GWEC) released its Annual Market Update this week, with a comprehensive snapshot of the global wind industry at the end of 2012, along with a five year forecast out to 2017. Although policy uncertainty in the main Organisation for Economic Co-operation and Development (OECD) markets is a cause for concern, strong markets in China, India and Brazil, as well as in new markets in Latin America, Africa and the rest of Asia will drive global growth during the period.
"Wind power may be variable, but the greatest threat to the continued stable growth of the industry is the variability and unpredictability of the politicians who set the frameworks for the energy sector," said Steve Sawyer, GWEC secretary general. "However, all of the fundamentals which have driven wind power to date are still in place: energy security, price stability, local economic development, climate change mitigation and local air and water pollution issues; and wind is now competitive in an increasing number of markets, despite fossil fuel subsidies which last year amounted to an incentive to emit CO2 of about $110/tonne."
Record installations in the U.S. and Europe led global installations of 44.8 gigawatts (GW) of new wind power globally in 2012, 10 percent more than was installed in 2011. Global installed capacity has now reached 282.5 GW, a cumulative increase of almost 19 percent. The forecast is for a modest downturn in 2013, however, followed by a recovery in 2014 and beyond; with global capacity growing at an average rate of 13.7 percent out to 2017, and global capacity nearly doubling to 536 GW.
The U.S. regained the number one spot for global markets in 2012 for the first time since 2009, eking out China by 164 megawatts (MW). However, the late extension of the U.S. Production Tax Credit on January 1 means that the U.S. market will drop precipitously in 2013, although with substantial recovery expected in 2014. Europe's record installations in 2012 are unlikely to be repeated in 2014, as a result of policy uncertainty and backtracking.
"European governments are driving up the cost of meeting their 2020 renewable energy targets by making policy changes that undermine investor confidence," said Thomas Becker, CEO of the European Wind Energy Association. "An ambitious and binding 2030 renewable energy target would hugely reduce uncertainty. It would create jobs and exports and boost Europe's world-leading wind industry."
After a year of market consolidation in China, the world's largest market with over 75 GW of installed capacity, Chinese authorities are calling for 18 GW of installations in 2013; and after a year-long policy hiatus in India, the market is expected to recover and return to growth in 2014. Brazil continues to lead the Latin American market, and may surpass 2 GW of annual installations in 2013; and both Mexico and Canada are expected to grow substantially over the period.
There are also hundreds of MW under construction in South Africa, with another 500 MW expected to come to financial close this year, leading a surge in installations in sub-Saharan Africa which began in Ethiopia in 2012. In Asia, Pakistan, Mongolia, the Philippines and Thailand are all expected to see significant installations in 2013 and beyond.

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:firstname.lastname@example.org" 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.
