Imagine paying less than $15 a month for electricity and gas. Imagine living in a home without air conditioning or heating vents. If the price sounds right, but the house itself sounds either drafty or stifling, think again.
If you were living in a passive house, you wouldn’t have traditional heating and cooling equipment, but you’d still be warm in the winter and cool in the summer. And your (more…)

The U.S. consumes a lot of fossil fuels from the burning of electricity inefficiently to driving inefficient cars and trucks on the highway. Politicians, the media, and others in society talk about the need for the U.S. to become energy efficient due to environmental reasons such as the threat posed by climate change if no action is taken. Yet, many policymakers are devoid (more…)

Decades ago the only type of car was the internal combustion (gasoline)type. Other varieties have arrived such as Hybrid and electric. With the new choices are other decisions such as which one reduces most the carbon footprint (or is the most green)and which one is the most cost effective. No more is “the miles per gallon” a standard that can be applied across the (more…)

“Most everyone has green materials that are made from recycled this or that. That is fine of course. But the public doesn’t really care. In fact the impact to our planet, or the savings to the impact to our planet is quite minimal if we recycle something. But if we drive CO2 down – that’s the high order bit – drive energy down, drive CO2 down. Those are the high order bits today.” – Kevin (more…)

The carbon footprint of the internet: Around 300 million tonnes of CO2 per year, equivalent to every person in the UK flying to America and back twice over.
All carbon footprints are hard or impossible to pin down accurately, but the internet is a particularly complex case. This isn’t just due to the fact that the “net” consists of (more…)

Taking a cue from of America’s most popular television shows, “The Biggest Loser,” The U.S. Environmental Protection Agency (EPA) is sponsoring a national energy contest entitled “Working off the Waste with Energy Star” among 14 commercial buildings across the country.
The 14 contestants will compete to demonstrate the largest percentage-based energy use reduction over a 12-month period from September 1, 2009 to August 31, 2010. The winning building will be announced in October 2010 in a public ceremony featuring Bob Harper, one of the winners of “The Biggest Loser.” (more…)

The drive to extract and store CO2 from coal-fired power plants is gaining momentum, with the Obama administration backing the technology and the world’s first capture and sequestration project now operating in the U.S. Two questions loom: Will carbon capture and storage be affordable? And will it be safe?
On a placid bend of the Ohio River in West Virginia sit two coal-fired power plants. The Philip Sporn Plant boasts four boilers from the 1950s, surrounded by mountains of coal and a series of man-made lakes to contain the toxic residue of its coal-burning.
A faint haze emanates from its main smokestack, the only visible sign of the thousands of tons of acid-rain-forming sulfur dioxide, smog-forming nitrogen oxides, and climate-warming carbon dioxide it emits each day, a consequence of the plant’s complete lack of pollution-control technologies. The 1,100 megawatts of electricity it produces will never benefit from such controls, as they are too expensive to install on the multiple small boilers, according to the plant’s owner, American Electric Power.

How good or how bad is a product from a green carbon footprint point of view? Several well known corporations like Airbus, Levi Strauss & Co., 3M, DuPont, and Kraft Foods are volunteering to road test a full life cycle greenhouse gas analysis on a wide range of products from blue jeans to manufactured steel.
A life cycle analysis studies all the potential contributions to a carbon footprint and includes supplier, transportation, production and disposal. This concept is also related to environmental sustainability.
