Energy Efficiency Providers Offer New Incentives
Posted on 09. Jul, 2010 by keith.
Cities across the U.S. are increasingly implementing green building ordinances or expanding the ones that they already have. However, in almost all cases, the ordinances are aimed at new construction or construction performed on existing buildings; that is, they do little if anything to affect the energy performance of older buildings, many of which figure to keep using their current technology until, one day, they end up replacing it with efficient technology because inefficient technology no longer exists.

When we hear about a company or organization “going green”, it’s easy to draw the impression that it will make itself environmentally friendly in one step. Sometimes, this is the case. But, just as often, going green amounts to a gradual process—a strategic approach of targeting the biggest problem areas first and then addressing smaller ones.

Achieving Energy Efficiency: Are Solar Panels Still A Good Choice?
Posted on 21. Jun, 2010 by keith.
Photovoltaic (PV) solar panels were one of the first forms of futuristic energy efficient technology. When they hit the market in the 1970’s, PV panels were expensive (roughly $450 a panel) and had a poor energy conversion rate (roughly 10 percent). Today, however, PV panels cost significantly less and have at least double the conversion rate of original panels.
