Highlights of 2010: Offshore wind in Texas and the curious case of Massachusetts

Humans have harnessed wind energy throughout history for milling, pumping and transportation — in a way you could say it’s the “original” form of industrial energy. But only recently have we built massive, powerful turbines to convert that wind into electricity. As concerns about pollution, carbon emissions, resource depletion and energy security mount, wind farms are an increasingly attractive alternative for meeting growing energy demand.

Wal-Mart to use wind energy

Wal-Mart’s reputation for cheap prices precedes it, but recently the retailer showed its greener side when it announced plans to supply 15 percent of its total energy load with wind power.

The energy will come from Texas wind farms constructed by Duke Energy, which will go online this spring, a Wal-Mart press release said.

That avoids releasing more than 139,000 metric tons of carbon dioxide emissions per year — the equivalent of taking about 25,000 cars off the road, Wal-Mart said.
