For GSS Energy Use chapter 5. Excerpt: ...Last year, wind power was the most prevalent source of new energy capacity — 43 percent of overall generation installed — while its price neared an all-time low, according to a recent report for the Department of Energy by Lawrence Berkeley National Laboratory. ...although the wind industry has been growing for decades, it is still relatively new at operating large-scale wind farms, so it is often only once a farm is up and running that some of the problems emerge, developers say. ...A number of factors can trigger curtailments in wind output, including reducing the danger to bats or birds flying around the spinning blades. But more commonly, regional grid managers, who must match demand and supply instantaneously, call for a reduction in wind power when more energy is produced than the system can safely transport, they say. .... http://www.nytimes.com/2013/08/15/business/energy-environment/intermittent-nature-of-green-power-is-challenge-for-utilities.html.
