Retrofitting Older Windows Shows Better Returns on Investment & Similar Energy Savings

October 3rd, 2012 | by Joshua S Hill

Residential buildings account for approximately 20 percent of the total U.S. energy use and carbon dioxide emissions, and one of the major inefficiencies in the average house is the commonplace window. Poor seals, inferior curtains, and a host of other factors can turn an older window into a critical problem for the energy and budget concious home-owner. However, a new study released Tuesday has shown that retrofitting older windows yields similar efficiency results as replacing them, but is also much cheaper than the alternative.


“Be an Energy Star” Video Challenge (+10 More Cleantech Stories of the Week)

August 21st, 2011 | by Zachary Shahan

Energy Star has a "Be an Energy Star" video challenge going on right now (on YouTube & Facebook), geared at highlighting the many great things people around the country are doing to save energy. Interestingly, I didn't run across news of this via any of my normal cleantech avenues, but found it on sister site sustainablog. Jeff over on sustainablog chose the video below as his favorite so far (though, there are still a number of videos to come, as the contest runs until September 16). I have to admit it's pretty cool and cute


U.S. Department of Energy Crowns New Energy Saving LED Kings

September 25th, 2010 | by Tina Casey

The U.S. Department of Energy has just named the winners of its eighth annual Lighting for Tomorrow competition, and the focus was squarely on new high efficiency LED designs that could help cut lighting energy use by 25 percent. LEDs (light emitting diodes) also have a big advantage over conventional bulbs when it comes to longevity, which could add even more on top of the $120 billion in energy savings that DOE expects from LEDs over the next 20 years - if enough building owners can be convinced to make the shift
