An Innovative Financing Tool That Makes Energy Efficiency Affordable

Energy upgrades like adding attic insulation can help consumers save money. Too often, however, homeowners can't afford this type of work. [Image credit: Clean Energy Economy / CC / Flickr] This post originally appeared at Ensia. For customers of the Roanoke Electric Cooperative in rural North Carolina, high energy costs are much more than a pesky bill or a grudging expense. “We’re one of the poorest areas of the nation,” says Curtis Wynn, the cooperative’s president and CEO. “We have a lot of low-income individuals who are our members and, quite frankly, a major portion of their monthly budgets are…


For Renewable Energy Advocates, the Tide Turns in Maine

After enduring eight years of Republican Governor Paul LePage, renewable energy advocates are breathing a sigh of relief as his Democratic successor settles into office. The state is deeply divided over a 145-mile power line that would slice through Maine’s pristine northern forests to deliver hydro power from Quebec to users in Massachusetts. But Governor Janet Mills, who took office in January, is helping to reverse the chilly reception given wind and solar energy by LePage and has pledged to push Maine toward 100% renewable energy by mid-century. Mills has lifted a moratorium on the development of wind energy that…


Electric Cars Could Make America’s Crumbling Roads Even Worse

As tax revenues from the sale of gasoline decline, there will be less money to pay for road repair. A tax on electricity at vehicle charging stations could solve that problem. [Image credit: Susan Sermoneta / CC BY-NC-ND / Flickr] U.S. roads and bridges are in abysmal shape — and that was before the recent winter storms made things even worse. In fact, the government rates over one-quarter of all urban interstates as in fair or poor condition. One-third of U.S. bridges need repair. To fix the potholes and crumbling roads, federal, state, and local governments rely on fuel taxes,…


Urban Rustic: Choosing and Installing a Ductless Minisplit

Editor’s note: This post is one of a series by Eric Whetzel about the design and construction of his house in Palatine, Illinois, a suburb of Chicago. A list of Eric’s previous posts appears below. For more details, see Eric’s blog, Kimchi & Kraut. The plan for our house was to combine an HRV or an ERV (for a continuous supply of fresh air) with a ductless minisplit air-source heat pump system for our ventilation, heating, and air conditioning needs. Almost all of the projects I had read about utilized this same combination, especially here in the U.S. The only…


Details for Insulating a Double-Stud Wall With Cellulose

Michael Sterner is ready to build a new house in northern Wisconsin: a simple, two-story box of about 2,000 square feet. After studying many possible wall assemblies, he has settled on the double-stud wall as proposed by the Building Science Corporation. The assembly consists of an inner 2×4 structural wall sheathed (on the outside) with 1/2-inch plywood and an outer 2×3 stud wall. Between the two there is a 4 1/2-inch space. Both stud cavities and the space between the two walls are insulated with cellulose. “We chose this wall for its high R-value to cost ratio,” Sterner writes in…
