This winter photo shows brightness where the most heat is escaping this home.

Cambridge! It’s finally here: a chance to vividly see the cool or warm air leaving your drafty home, without having to pay hefty fees to a thermal photographer. Thanks to the Thermal Imaging Project on which HEET has partnered with Sagewell Inc., Cambridge homeowners can request thermal (infrared) images of the outsides of their homes.

The images are taken with car-mounted cameras similar to those used for Google Maps street view, and taken on a “first come, first served” basis – with highest priority given to locations with highest demand.  With the slight air of a Groupon deal, Sagewell has asked for 400 requests from Cambridge before they will release our thermal images for free.

What is common between the beach, the pool , cold showers and lemonades ?

Water !

Even though water seems like it is an unlimited resource, is in reality a limited resource because there are no known new sources of water. Americans consume about 150 gallons of water every day, which is twice the world average. Water needs energy to be transported and has a huge environmental impact. More water required means more dams and reservoirs, which in turn means more damage to marine habitat.

Check out National Geographic’s water footprint calculator to discover how you use water and calculate your footprint.

Here are things you can do to conserve water and do your part to save the environment :

Residents of Cambridge, MA were introduced to a new opportunity on February 8th, 2011. Energy efficiency is on the minds of renters, condominium owners, and homeowners alike as the environmental, financial, and physical benefits become more prominently appreciated. Usually when energy efficiency information is available, it is more general and further discussion with specific professionals is suggested, since the process of making home energy efficiency improvements is tailored to unique home and ownership characteristics and often entails several detailed levels of complexity. On February 8th, those professionals were brought together in one place for an evening of sequential enlightenment for curious attendees, with an added bonus of networking amongst their industry peers and less-assumed partners, Green real estate agents.

CEA canvassing interns: Stephanie, Mira, Danit, Trevor, Federico, Laurence

On July 7th CEA’s six volunteers took to the streets for the first time, canvassing businesses in Inman Square, and eastward on Cambridge Street. Over the next three weeks, they would reach out to over 440 people in small local businesses—barber shops, cafes, hardware stores, book stores, florists, bars, convenience stores, restaurants, bike shops, you name it—in North Cambridge, Leslie and Porter Square, Harvard Square and Church Street, Mount Auburn and Brattle Street, Dana Hill, Bow Street, Central Square, Lafayette, Concord Ave, Huron, East Cambridge, and Broadway.

In 90+ degree heat, over previously unfamiliar terrain, and sometimes through rain storms, the teams of interns  met with over 190 business owners and discussed energy efficiency opportunities—programs and incentives from… [view entry]

It’s a huge success. It hasn’t gone anywhere. Actually, it’s a little of both.

Fifty states and six territories have launched “Cash for Appliances” programs since late last year. Each one had the same amount of money – about a dollar per resident – but the results have been wildly different. Some states ran through their entire rebate budgets in hours; others can’t seem to give away their money. What’s been going on?

Cash for Appliances, modeled on (or at least nicknamed after) last year’s “Cash for Clunkers” program, was funded as part of the $787 billion stimulus bill. Unlike “Cash for Clunkers”, the appliance rebate program wasn’t designed and administered by the federal government. Instead, the government directed $300 million to the 50 states (plus DC and several American territories), at… [view entry]

Starting Wednesday, July 7th, a city-wide canvass will be visiting Cambridge business squares, bringing money- and planet-saving opportunities to the doors of hundreds of small businesses.  Canvassers will talk with business owners about what they can do to make their businesses more energy efficient, supplying them with ample information about which programs to employ to best suit their needs. During these short interactions, businesses will have the chance to sign up for a free energy assessment, and connect with other community resources including:

The City of Cambridge Facade Improvement Program provides technical and financial assistance to property owners or tenants seeking to renovate or restore commercial building exterior facades.

The light-emitting diodes (LEDs) are becoming more and more common in traffic lights and are moving into streetlights.

LEDs produce three or four times more light per watt of electricity than standard incandescent lamps do, and they are more than 4 times as efficient as Compact Fluorescent Light (CFL) bulbs, typically lasting  up to 50,000 hours.

The Dialight Corporation, of Farmingdale, N.J., a subsidiary of a British company,  has about one-third of the United States market for LED traffic signals, and is now looking forwards on another target: street lamps. Edinburgh and Pittsburgh are already trying this new lightning system. Even if LED street lamps doesn’t produce much more light per watt than a conventional lamp, it’s strength is to shine in only one direction whereas other lamps shine… [view entry]

The current green revolution looks to renewable energy and green products to replace the polluting industries of the modern era.  What is often left out of the discussion is our relationship with the living biosphere and how our technology much revolutionize itself to not just being low-carbon, but operate under the principles of how nature organizes itself.  Janine Benyus, a scientist and founder of the company Biomimicry Guild, has been looking to nature to develop technologies that maximize efficiency prinicples inherent in the natural world.  This new movement, labeled biomimicry, asks homo sapiens sapiens to tap into the intellengence of nature in our design principles.  The natural world is not seen as a dumb organic machine, but rather a dynamic force… [view entry]

From the “Game of Life’ Files, comes this stub about Adaptive Meter, a company who has invented an internet application that makes energy conservation an engaging game.

The company, which makes web applications such as Stickychicken and Twitterlike, is developing an interactive gaming platform in which players bet on others’ energy usage. The stock-market style game, called Lost Joules, will use smart-meter data from consenting players, and other participants—including those without smart meter —will be able to stake virtual cash on whether those players can reduce their energy use or not.
