In China, wind power is leaving nuclear behind. Electricity output from China’s wind farms exceeded that from its nuclear plants for the first time in 2012, by a narrow margin. Then in 2013, wind pulled away—outdoing nuclear by 22 percent.
The 135 terawatt-hours of Chinese wind-generated electricity in 2013 would be nearly enough to power New York State.
Once China’s Renewable Energy Law established the development framework for renewables in 2005, the stage was set for wind’s exponential growth. Wind generating capacity more than doubled each year from 2006 to 2009 and has since increased by nearly 40 percent annually, to reach 91 gigawatts by the end of 2013 (1 gigawatt = 1,000 megawatts). Over 80 percent of this world-leading wind capacity is now feeding electricity to the grid.
Wind generation in 2013 could have been even higher, by an estimated 10 percent, but for the problem known as curtailment—when wind turbines are stopped because the grid cannot handle any more electricity. To help reduce curtailment and reach the official 2020 goal of 200 grid-connected gigawatts, China is building the world’s largest ultra-high-voltage transmission system. The raft of projects now under construction will connect the windier north and west to population centers in the central and eastern provinces.
One of the reasons why nuclear power has not kept up with wind in China is the relative time it takes to get a project up and running. Whereas the typical Chinese nuclear reactor takes roughly six years to build, a wind farm can be completed in a matter of months.
Another factor was the interruption of China’s nuclear expansion after the 2011 disaster in Fukushima, Japan. The government suspended new reactor approvals until late 2012 and reviewed the safety of both operational and under-construction reactors over several months. Officials also deferred until at least 2015 plans for reactors in non-coastal provinces, where water needed for cooling is highly polluted and in increasingly short supply.
If all 28 gigawatts of nuclear capacity now under construction are completed by 2020, China will have reached 45 gigawatts—22 percent shy of the official capacity target of 58 gigawatts. Some of the more-advanced reactors now being built are seeing cost overruns and schedule delays of a year or more, so the nuclear fleet in 2020 may be even further from the official goal.
Despite its impressive recent growth, wind power still provides less than 3 percent of China’s electricity, well behind hydropower (which typically makes up about 17 percent) and coal, the leading electricity source (at more than 75 percent). But as wind power opens up an even greater lead over nuclear, it is showing the potential to emerge as the safe, scalable, water-sparing backbone of a low-carbon Chinese energy economy.

Returning the ‘Three Sisters’ – Corn, Beans and Squash – to Native American Farms Nourishes People, Land and Cultures
By Christina Gish Hill
Historians know that turkey and corn were part of the first Thanksgiving, when Wampanoag peoples shared a harvest meal with the pilgrims of Plymouth plantation in Massachusetts. And traditional Native American farming practices tell us that squash and beans likely were part of that 1621 dinner too.
Abundant Harvests<p>Historically, Native people throughout the Americas bred indigenous plant varieties specific to the growing conditions of their homelands. They selected seeds for many different traits, such as <a href="https://emergencemagazine.org/story/corn-tastes-better/" target="_blank" rel="noopener noreferrer">flavor, texture and color</a>.</p><p>Native growers knew that planting corn, beans, squash and sunflowers together produced mutual benefits. Corn stalks created a trellis for beans to climb, and beans' twining vines secured the corn in high winds. They also certainly observed that corn and bean plants growing together tended to be healthier than when raised separately. Today we know the reason: Bacteria living on bean plant roots pull nitrogen – an essential plant nutrient – from the air and <a href="http://www.tilthalliance.org/learn/resources-1/almanac/october/octobermngg" target="_blank" rel="noopener noreferrer">convert it to a form that both beans and corn can use</a>.</p><p>Squash plants contributed by shading the ground with their broad leaves, preventing weeds from growing and retaining water in the soil. Heritage squash varieties also had spines that discouraged deer and raccoons from visiting the garden for a snack. And sunflowers planted around the edges of the garden created a natural fence, protecting other plants from wind and animals and attracting pollinators.</p><p>Interplanting these agricultural sisters produced bountiful harvests that sustained large Native communities and <a href="http://dx.doi.org/10.1353/eam.2015.0016" target="_blank">spurred fruitful trade economies</a>. The first Europeans who reached the Americas were shocked at the abundant food crops they found. My research is exploring how, 200 years ago, Native American agriculturalists around the Great Lakes and along the Missouri and Red rivers fed fur traders with their diverse vegetable products.</p>
Displaced From the Land<p>As Euro-Americans settled permanently on the most fertile North American lands and acquired seeds that Native growers had carefully bred, they imposed policies that <a href="https://doi.org/10.1086/ahr/87.2.550" target="_blank">made Native farming practices impossible</a>. In 1830 President Andrew Jackson signed the <a href="https://guides.loc.gov/indian-removal-act" target="_blank">Indian Removal Act</a>, which made it official U.S. policy to force Native peoples from their home locations, pushing them onto subpar lands.</p><p>On reservations, U.S. government officials discouraged Native women from cultivating anything larger than small garden plots and pressured Native men to practice Euro-American style monoculture. Allotment policies assigned small plots to nuclear families, further limiting Native Americans' access to land and preventing them from using communal farming practices.</p><p>Native children were forced to attend boarding schools, where they had no opportunity to <a href="https://doi.org/10.5749/jamerindieduc.57.1.0145" target="_blank">learn Native agriculture techniques or preservation and preparation of Indigenous foods</a>. Instead they were forced to eat Western foods, turning their palates away from their traditional preferences. Taken together, these policies <a href="https://kansaspress.ku.edu/978-0-7006-0802-7.html" target="_blank" rel="noopener noreferrer">almost entirely eradicated three sisters agriculture</a> from Native communities in the Midwest by the 1930s.</p>
Reviving Native Agriculture<p>Today Native people all over the U.S. are working diligently to <a href="https://www.oupress.com/books/15107980/indigenous-food-sovereignty-in-the-united-sta" target="_blank" rel="noopener noreferrer">reclaim Indigenous varieties of corn, beans, squash, sunflowers and other crops</a>. This effort is important for many reasons.</p><p>Improving Native people's access to healthy, culturally appropriate foods will help lower rates of <a href="https://www.cdc.gov/vitalsigns/aian-diabetes/index.html" target="_blank">diabetes</a> and <a href="https://www.apa.org/pi/oema/resources/ethnicity-health/native-american/obesity" target="_blank">obesity</a>, which affect Native Americans at disproportionately high rates. Sharing traditional knowledge about agriculture is a way for elders to pass cultural information along to younger generations. Indigenous growing techniques also protect the lands that Native nations now inhabit, and can potentially benefit the wider ecosystems around them.</p>

Amid reports that oil industry-friendly former Energy Secretary Ernest Moniz remains under consideration to return to his old post in the incoming Biden administration, a diverse coalition of environmental groups is mobilizing for an "all-out push" to keep Moniz away from the White House and demand a cabinet willing to boldly confront the corporations responsible for the climate emergency.
