Report Gauges Future of Untapped Renewable Energy

Posted on April 19,2015 by ScottG in energy subsidies

The cost of solar and wind energy in western states of the U.S. will be cost competitive with natural gas by 2025 even without government subsidies, a report from the National Renewable Energy Laboratory suggests.

Rebuilding in Tornado Country

Posted on April 19,2015 by ScottG in FEMA

Tornadoes have struck the Midwest with a vengeance this year, killing dozens of people and causing widespread destruction of property. In the city of Moore, Oklahoma, a tornado with winds topping 200 miles per hour struck on May 20, reducing whole neighborhoods to rubble. Many homeowners will rebuild, so what should their new houses look like? In a post at GreenBuildingAdvisor's Q&A forum, David Gregory raises that question.

North Carolina Mulls Renewable Energy Rollback

A bill narrowly approved by a North Carolina legislative committee would repeal renewable energy requirements established in 2007.

Commercial-Scale Wind Power

Last week I wrote about the challenges of small wind turbines and the difficulty of successfully integrating wind power into buildings. This week, I’ll look at larger-scale commercial wind power developments.

Wind Power: Why it Doesn’t Make Sense Everywhere

Posted on April 19,2015 by AlexWilson in building-integrated wind

At least in our neck of the woods, wind power is very much in the news these days. The Vermont legislature is debating whether to institute a three-year moratorium on what detractors refer to as “industrial wind power,” and debate is raging in the nearby towns of Windham and Grafton, Vermont about a potential wind farm. I figured I should weigh in.

Wind Power Getting Cheaper, Turbines More Efficient

Posted on April 19,2015 by Fretboard in wind

Back in 2007, the output capacity of utility-scale wind turbines in the U.S. was a little over 16,500 megawatts – a tiny fraction of what would be required to meet overall demand, but still enough to make the wind industry a viable, emerging player in electricity generation.

Utility Wind Energy: Bad News for Bears

Posted on April 19,2015 by Tristan Roberts in wind

Author's Note: Please see the comment thread at the bottom of this article for more discussion on the width of the ridgeline road. Since posting this article I learned of other permitting documents indicating a much narrower road than discussed in this article. One of my favorite pieces of Vermont trivia has been that the tallest man-made structure in the state is the Bennington Battle Monument, at 306 feet tall — and construction of it was completed in 1889.

Utility-Scale Wind Turbines

Posted on April 19,2015 by user-756436 in renewable energy

I live in Wheelock, Vermont, a town with 598 residents. Our town is so small that we have neither a post office nor a zip code. To get my mail, I have to travel two miles to the post office in Sheffield, our larger neighbor. (Sheffield has a population of 704.) There’s a $90 million construction project underway in Sheffield this summer. In its entire 200-year history, the sleepy town has never seen anything like this.

7 Steps to an Energy-Efficient House: 7. Renewable Energy

Posted on April 19,2015 by Betsy Pettit in hydro

Editor's introduction: With energy prices rising again, many homeowners are planning energy-efficiency improvements to their homes. But most people are unsure of where to begin, and even seasoned builders don’t always know which priorities should rise to the top of the list. Betsy Pettit, an architect at [Building Science Corporation](, recommends starting where you can get the most bang for the buck.
