PacifiCorp Looks To Expand Wind Energy As Coal Plants Retire

Jun 29, 2017

PacifiCorp is moving forward with a 20-year plan that reduces its use of coal-fired power while expanding investments in wind energy.

The utility, which serves customers in six Western states, has proposed spending $3.5 billion on a plan to add 1,100 megawatts of new wind energy — mostly in Wyoming — as well as a new transmission line.

The plan will also re-power wind turbines in the Columbia River Gorge by adding bigger turbine blades and upgrading equipment inside the turbines to increase their energy output by an average of 20 percent.

Northwest rivers are running high as all that winter snowpack melts into spring runoff.

And that means the region is producing too much of a good thing: carbon-free, renewable energy in the form of both dam-generated hydropower along with electricity from spinning wind-farm turbines.

That's prompted the federal government to take an action it avoided during the last four years of drought conditions: shutting down wind power.

Aboard a ferry off the coast of Rhode Island, state and federal officials take a close look at a steel structure poking out of the ocean. It's the first foundation affixed to the seafloor for a five-turbine wind farm off the state's coast.

It's a contrast to what's happening off the coast of Massachusetts. Developer Cape Wind has spent more than 10 years and millions of dollars there on a massive wind farm that it may never build.

Wind Tax Credit Set To Expire, Again

Dec 23, 2013

A tax credit that wind energy advocates say is important to sustaining the industry is set to expire Dec. 31. Wind developers say the tax credit is critical to the growing industry. Without it, wind turbine manufacturing can grind to a halt, as it did after the credit expired in 2012.

More than 600,000 bats may have been killed at wind farms in the continental US last year. That’s trouble for agriculture: the US Geological Survey estimated in 2011 that the bats’ natural pest-control saves the industry at least $3 billion a year.

Harvesting Wind Power With Philip Warburg

Wind can be a very significant power provider in the United States, especially in the Midwest. Environmental lawyer and writer Philip Warburg talks about wind as a resource, including how it relates to the economy and climate change. He spoke at Seattle's Town Hall on December 4, 2012. The talk was introduced by Denis Hayes, CEO of the Bullitt Foundation and coordinator of the first Earth Day.
