New Study Confirms China Is the Chief Source of Banned Gas

Maillard / CC BY-NC-ND / Flickr] Two industrialized provinces in eastern China are responsible for most of an increase in emissions of a banned chemical that depletes the Earth’s ozone layer, scientists say in a recently released report. New observations confirm the suspicions of scientists who said last year that they had detected increased emissions of CFC-11, a chlorofluorocarbon once widely used as a blowing agent in foam insulation.

Democrats Seek Extension of Tax Breaks for Renewables

Wind farms, like this one in Idaho, would benefit from an effort in Congress to extend tax breaks for renewable energy. [Photo credit: Jerry and Pat Donaho / CC NC-ND / Flickr] Federal tax credits for wind and solar systems are to be phased out beginning next year as part of a 2015 deal that ended a ban on crude oil exports. Now, a group of Democrats in Congress would like rework the plan and keep the subsidies in place, Bloomberg reports. The 2015 agreement was a boon for renewables. A production tax credit for the wind industry, which had…

Lessons from Asheville’s First Zero Energy Ready Home

The Department of Energy would like builders to up their game. Though the energy savings achieved by the DOE’s Energy Star Homes program (said to be 20%) is worth celebrating, it’s possible these days to build homes that are even more energy efficient than that. It’s even possible while also delivering other key benefits:  improved comfort, reduced water use, the best possible indoor air quality, and the ability to seamlessly integrate a photovoltaic (PV) system. The DOE thinks it’s time for more new homes to take that step. Enter the Zero Energy Ready Home program. Launched in 2013 as an…

Should We Install a Whole-House Fan?

Writing from St. Paul, Minnesota, W Ramsay wants some feedback on his plan to install whole-house ventilation fans in the house he’s building. He likes the idea, the building inspector does not. Ramsay sees the benefits of improved indoor air quality and energy-efficient cooling, while the inspector is apparently concerned that the fans would depressurize the house and possibly lead to backdrafting of combustion appliances. Originally, the inspector was prepared to require a 1:1 makeup air system, which would not only be expensive but also defeat the purpose of the fans, Ramsay says. The inspector backed off that original request…
