The biggest uses of energy, looked at through the lens of efficiency, is the power we waste through inferior technology, unoccupied rooms and lack of smart programming of heating and cooling.

EVERYWHERE WE LOOK, we’re using energy - whether it’s burning gasoline to power our cars, lighting our homes and workplaces, or powering the systems underlying the modern internet, our mastery of energy is the bedrock of society.

The Five Best Green Building Ideas This Century (So Far)

Posted by Matt Power, Editor-In-Chief

A lot of the really groundbreaking stuff going on in green building happens behind the walls, so of course you might never notice it.


The building industry is notoriously slow to change, but when the global recession hit a few years ago, smart builders carved a green niche to save their companies. Eco-friendly construction tends to continue, even when times are relatively bad, motivated by the idea of saving money on energy, water, and so on.

What's really changed in the past couple of decades? Here's my short list of some of the best and brightest ideas, and why they matter:

LED Lighting. Finally, we can stop cursing our compact fluorescent lamps. Unlike fluorescent lamps, which rarely live up to their promised of 10,000 hour lifespans, contain enough mercury to classify as hazardous waste and make your complexion look like undead zombie flesh, LED bulbs do it all. They' use a fraction of the energy of a CFL, come in dimmable versions that change color warmly, last up to 50,000 hours, and don't contain mercury. Win, win, win. Another new entry into this category are LED replacement lamps for fluorescent fixtures. This is a major upgrade in terms of both performance and sustainability. The common 4-ft. lamps in fluorescent lamps contain hazardous mercury, and we all know they don't last as long as they should. A comparable LED replacement lamp uses half the power, comes on instantly, and could last 50,000 hours, compared to about 8,000 hours for CFLs.
