Industrial strength energy efficiency

Industrial strength energy efficiency | Sustainable Energy | Scoop.it

What do you think of when you hear the phrase, “energy efficiency?”  Compact fluorescent (CFL) lighting?  Maybe Energy Star appliances or adding insulation to your attic.

What all of these things have in common is that they are all residential solutions, but despite their greater numbers residential customers use far less electricity than do commercial and industrial customers.  Certain industries (e.g. cement, steel, aluminum) use enormous amounts of power, but the efficiency conversation rarely touches on these users.

That’s unfortunate because industry is where the big potential savings are.  Consider that while all lighting (residential, commercial, industrial combined) accounts for around 5.5 percent of total electricity consumption, electric motors in industrial applications alone use nearly five times as much, fully 25 percent of all electricity consumption.

Back to the future: lifting a page from ancient architects' playbook

Back to the future: lifting a page from ancient architects' playbook | Sustainable Energy | Scoop.it
Some would have us believe that construction regulations are new. Have you ever heard of the Code of Hammurabi? It’s the very first code of laws known in history, dating back to 1750 BC. And guess what? Building codes were already included! 6 out of 282 laws regulated construction safety, including penalties for builders of non-compliant homes.

The architectural solutions for cooling homes have been around for a while.

What is Earthship ?

What is Earthship ? | Sustainable Energy | Scoop.it

An Earthship is a type of passive solar home made of natural and recycled materials. Designed and marketed by Earthship Biotecture of Taos, New Mexico, the homes are primarily constructed to work autonomously and are generally made of earth-filled tires, using thermal mass construction to naturally regulate indoor temperature. They also usually have their own special natural ventilation system. Earthships are generally Off-the-grid homes, minimizing their reliance on public utilities and fossil fuels.
