Drive-By Heat Mapping

January 9, 2015 by Energy @ MIT

Home Heat Mapping and Energy Efficiency

In 2007, Google unleashed a fleet of cars with roof-mounted cameras to provide street-level images of roads around the world. Now MIT spinout Essess is bringing similar “drive-by” innovations to energy efficiency in homes and businesses.[read more]

Advanced Energy Technology of the Week: Industrial CHP

September 7, 2014 by Matt Stanberry

Industrial CHP


Industrial Combined Heat and Power (CHP, also called cogeneration) uses a single fuel, often natural gas, to co-produce electricity and heat for use in industrial operations, usually on-site. Industrial CHP accounts for more than 75 GW out of the approximately 82 GW of installed CHP in the United States.[read more]

Advanced Energy Technology of the Week: Combined Heat and Power (CHP)

August 21, 2014 by Matt Stanberry

Combined Heat and Power

Combined Heat and Power, also called cogeneration, generates both electricity and useful heat from the same fuel source. CHP typically involves dedicated equipment to generate electricity, followed by recovery of exhaust/waste heat for use in industrial processes, space heating, or water heating.[read more]

Running on Waste Heat

August 9, 2014 by Energy @ MIT

Waste Heat and Power

It’s estimated that more than half of U.S. energy — from vehicles and heavy equipment, for instance — is wasted as heat. Mostly, this waste heat simply escapes into the air. But that’s beginning to change, thanks to thermoelectric innovators such as MIT’s Gang Chen.[read more]

What Are the Sources of Home Heat Loss?

November 27, 2013 by Lindsay Wilson

Home Heat Loss

Because a house remains roughly the same temperature over the course of a year its heat gains are equal to its heat losses. We can thank the first law of thermodynamics for this. Heat gains come from heating systems, the sun’s warmth and internal gains from things like appliances and body heat.[read more]
