MINNEAPOLIS / ST. PAUL — Minnesota’s Iron Range is pocked with ponds – abandoned open pit mines – that could help energy providers more efficiently use intermittent renewable energy sources, such as wind, to meet state renewable energy mandates. A study released Friday by the University of Minnesota Duluth’s Natural Resources Research Institute shows that the water-laden pits have the potential to store wind energy using a process developed in Europe in the late 1800s.

The pumped-hydro storage process would use excess late-night wind energy to pump water uphill from the pits to a higher-elevation holding pond. Then, when electricity demand goes up during the day, the process reverses the flow and captures the energy in hydro turbines. For every 100 megawatts used to pump the water upward, the plant generates nearly 80 megawatts through the turbines. (more…)

Are You Alarmed or Dismissive? Americans’ Latest Views on Climate Change Fall Into One of ‘Six Americas’

In a new report, researchers have found that Americans have a wide range of attitudes and beliefs when it comes to climate change, yet also show some surprising similarities. The report, which is the latest in a series from the Yale University Project on Climate Change Communication, demonstrates how Americans fall into one of six categories called the “Global Warming’s Six Americas,” each reflecting different attitudes and behaviors when it comes to climate change.

*Climate models predict stable wind energy patterns over the United States*

Rising global temperatures will not significantly affect wind energy production in the United States concludes a new study published this week in the Proceedings of the National Academy of Sciences Early Edition.

But warmer temperatures could make wind energy somewhat more plentiful say two Indiana University (IU) Bloomington scientists funded by the National Science Foundation (NSF). (more…)
