How “Phantom Loads” Are Hurting Your Energy Bill and the Environment

Annika Tostengard — Thu, 10 Dec 2015 18:56:09 +0000

“Phantom loads” are electronics that always run, regardless of whether they are being used or not. Most people are aware of the harm that these electronics can have on the environment: inefficient electricity use greatly increases the output of the coal plants that supply power and, therefore, increases fossil fuel emissions into the atmosphere. Unplugging […]

4 Ways to Use Less Energy at Home

Annika Tostengard — Tue, 17 Nov 2015 12:56:03 +0000

The Department of Energy has several recommendations as to how homeowners can use less energy and save on their energy bills, especially during the winter when heaters are often on full blast. Homes in the United States have also grown about 30% larger since 2000 while using just 2% more energy, thanks to much-improved materials […]

Don’t let anyone tell you any differently, but size does matter. This is just as true when we take a look at how computing power has advanced over the decades. The larger the machine, the more power it consumes. Conversely, smaller machines are more efficient. Take, for instance, the ENIAC [Electronic Numerical Integrator And Computer] […]
