You’ve probably never considered crowds to be a renewable source of energy. Lucky for us, two smarty-pants grad students at MIT’s School of Architecture and Planning are trying to figure it out.

James Graham and Thaddeus Jusczyk envision harvesting the mechanical energy from human movement – like commuters in a train station or fans at a rock concert – for electricity. This “crowd farm” would be a responsive sub-flooring system and made up of blocks that depress slightly when people step on them. When the blocks slip against each other they would generate power through the principle of the dynamo, a device that converts the energy of motion into that of an electric current.

Crowds of people at a train station aren’t going to be enough to power the train itself: Graham and Jusczyk explain that thousands of people would be needed to make up the 28,527 steps needed to power a moving train for one second. But for smaller, very energy-efficient devices, the students’ idea could lead to something bigger: Their test case included a prototype stool that used the act of sitting to generate power. The weight of the body on the seat causes a flywheel to spin, which powers a dynamo that lights four LEDs (super-efficient lightbulbs).

The architecture students ultimately want an energy supply that’s integrated into a new sort of building system, one that harnesses the active power of humans to power a cleaner, more efficient lifestyle in the 21st century.

A group of 13 Canadian companies and nongovernmental organizations (NGOs) have launched a pilot program in British Columbia (BC) to help the 370,000 small and medium-sized businesses there cut their global warming pollution.

Ecotrust Canada, the Pembina Institute, the David Suzuki Foundation, and corporate partners have developed the Carbon Neutral Workgroup for Small Business, which will help companies calculate their global warming emissions and identify efficient means of reducing those emissions. Even better, the group wants to create free software for small and medium-sized business to show them how to cut their carbon footprints. The Pembina Institute, an NGO that provides education and consulting on clean energy issues, will offer one-on-one technical assistance.

The Workgroup points out that small businesses are responsible for about 30 percent of BC’s gross domestic product (GDP), making it a significant market in which to cut climate change emissions. Ian Gill, President of Ecotrust Canada, explained:

“It’s part of a growing ‘conservation economy’ driven by the dramatic change in consumer and corporate attitudes toward the environment as a result of global warming.” But no one is “talking or thinking about how” to help small businesses.

Small business owners will also learn about the emerging carbon offsets market, thereby giving them more tools with which to reinvest money into climate change projects in their local communities and offset their emissions.

Businesses involved in the Workgroup so far include an architecture firm, a bus company, fisheries, and a flooring and upholstery service.

A new nonprofit group called Climate Counts has released its first annual scorecard ranking companies on what they are doing to slow climate change. Specifically, 56 consumer businesses in eight categories were examined on how they measure global warming emissions, their plans to reduce them, their support or opposition to regulation and – the most important to their ultimate score – how fully they disclose those activities.

No company achieved the perfect score of 100 and only four scored a 70 or better: Canon, IBM, Nike, and the consumer foods giant Unilever. Six companies scored zero: Jones Apparel Group, CBS Corp., Burger King Holdings Inc., Darden Restaurants Inc., Wendy's International Inc. and Amazon.com. Even yogurt-maker Stonyfield Farm, which provided $500,000 in seed money for Climate Counts and whose CEO chairs the group, scored only a 63 because of lack of disclosure and lagging use of renewable energy.

Companies that scored much higher than their competitors were thrilled, of course. Coca-Cola scored a 57 compared to PepsiCo’s 26. Jeff Seabright, Coca-Cola’s vice president for environment and water resources, told the New York Times "Data shows that environment is an increasing part of informed consumer choice and this score recognizes our leadership.”

Other companies were not happy with their scores, especially if they were low because of disclosure issues. Avon Products scored an 11, but its director of corporate responsibility explained that the company has been “quietly” doing the right thing by making strides in energy efficiency, recycling, and packaging reductions for years.

I’m impressed with the usability of Climate Counts information: The website has a handy pocket guide that ranks the companies by sector (making it easy to take with you shopping) and soon a company’s ranking may be available via cell phone.

What do you do when you’ve got a problem like communicating the need for renewable, efficient energy to hundreds of millions of people? Harness the web, of course.

SmartPower, a nonprofit marketing organization that promotes clean energy, used YouTube to form the Clean Energy Challenge. The aim was to create an ad for SmartPower around the belief that “clean energy is real. It’s here. And it’s working.”

After reviewing 150 submissions (not a ton, but not bad for such a wonky topic whose actors have virtually no chance of finding a mate on national TV), the $10,000 winner has been chosen. But in the true style of any reality show, the final results are drawn out over several days. The top 10 ads were posted on June 10th and for every day until the 18th one ad will be removed, finally leaving the “last ad standing” on Monday.

The winner will be announced via webcast at 5:00PM on June 18th and all finalists voted off are highlighted on the SmartPower Blog.

I was impressed with the quality of most of the finalists – these weren’t all made in someone’s basement. I’m a big fan of “Reading Light” and “Time Machine” because they made me laugh. And the kid in “It’s Your Choice” is really quite good. What's your favorite?

Earlier this spring, U.S. House Speaker Nancy Pelosi created the House Select Committee on Energy Independence and Global Warming. Although it has no legislative-making power, it can study and make recommendations on the problem. This week it took on an American icon: the Smithsonian Institution.

The Committee is investigating allegations by former associate director of the National Museum of Natural History, Robert Sullivan, that Smithsonian officials toned down a climate change exhibit to avoid angering some members of Congress and the Bush administration.

Sullivan charges that the exhibit’s text was rewritten to make the connection between climate change and human activity more uncertain. The Smithsonian has denied the allegations, pointing out that Sullivan “was neither a scientists nor a curator.” Other scientists and curators have said that nothing major was omitted, although some admitted to political sensitivities. John Calder, a lead climate scientist at the National Oceanic and Atmospheric Administration told the Associated Press:

"I remember them telling me there was an attempt to make sure there was nothing in there that would be upsetting to any politicians. They're not stupid. They don't want to upset the people who pay them."

The Natural Resources Defense Council had considered co-sponsoring the climate change exhibit but objected to the exhibit's text about uncertainties on the future warming of the planet.

Will Steger, famed polar explorer whose feats include the first confirmed dogsled journey to the North Pole without re-supply, the longest unsupported dogsled expedition in history (1,600 mile south-north traverse of Greenland), and the first dogsled traverse of Antarctica, is now on a new mission. He is an eyewitness to the impacts of global warming, both in the Polar Regions and in his home state of Minnesota. A former science teacher, he has set out to educate people on global warming and the solutions needed to slow it. He returned last week from a four-month trek by dogsled across Baffin Island in the Canadian Arctic to interview the Inuit people, who have had to adapt quickly to a new lifestyle because of climate change. Steger will use these interviews to produce a documentary later this year.

I spoke with Will by phone on May 15th. He was in Iglulik, Nunavut; the last stop of his expedition.

Green Options: You’ve traveled both Polar Regions extensively and have documented how climate change is drastically changing their landscapes. What was different about this trip?

Will Steger: This was a new route for me because this was a cultural expedition. We specifically planned the route so we could visit as many villages and talk with as many people along the way as possible. We know global warming is happening and we want to put a human face on it. So we spent a lot of time in villages. Our team included myself, three team members, and three 50- or 60-year-old Inuit hunters. We talked with hundreds of people.

Baffin Island, where I traveled, is like ground zero of global warming because there’s an intact culture that relies very heavily on their surroundings to survive. Changes are noticed almost immediately. Up here, global warming is showing itself most drastically out on the sea ice. As the earth warms, 80 percent of that energy goes into the ocean, which then affects the ice cover. The Inuit are seeing the ice freeze six weeks later, along with earlier break ups of the ice. Generally, the Inuit have had about 8 months where they are able to travel on the ice to hunt, and now that’s cut down to 5 or 6 months. That’s a 25 percent reduction in the amount of time they have to hunt out on the ice, which acts like an extension of their land.

GO: Are the Inuit angry? It is industrialized countries’ pollution that has caused this.

WS: Everyone is talking about global warming up here, there’s no denial about it. But the Inuit are forgiving people. Many of them aren’t worried about it because they can’t change it, and they don’t worry about things they can’t change. They understand that the polluters are industrialized nations, but in general they don’t harbor a lot of anger. They wish we would change, but they’re pretty easy going.

But we still have to take responsibility. Our way of consuming energy is really causing this, and we need to change to avoid the worst of the consequences.

GO: You’ve documented the changes up there before; did anything surprise you about this trip?

WS: Let me first say that no single event “proves” global warming. Global warming is an accumulation of changes happening over time. That said, I did see an effect that really surprised me, and everyone up there was talking about it: There is a large sound called Cumberland Sound. It’s about 50 miles wide and 125 miles long, and we were going to cross it on this expedition. But the ice broke up from the swells from a super storm in the North Atlantic. Everyone was talking about that. So we had to go around it, which was an extra 75 miles. That’s not a major hardship for the team, but it is for the Inuit communities because they depend on the sound for commercial fishing. Now it has shattered the fishing industry. It isn't just abou the environment; it’s the fact that it affects the economy and survival of this entire community.

Another impact really struck me. There’s a place up here they call the “land where ice never melts.” Well, it is melting. The glaciers are shrinking. That was incredibly powerful to see.

GO: Seeing all these impacts from climate change, was this trip depressing or invigorating?

WS: Neither. It was reaffirming: We were ground-truthing the science.

You have to understand that this Inuit culture does not think the way we do. Their world is close to the land. They talk in minute details of the changes in the salt in the sea ice, details that aren’t even in the climate change models. You rely on a lot of satellite info up here, but there aren’t a lot of scientists.

GO: How do the Inuit talk about global warming?

WS: Many of the elders will say the earth’s axis has changed because the sun is rising in a different place. But what’s really happening is that, because our warming planet causes more water to be absorbed up into the atmosphere, they are seeing a diffraction of the sun. It’s like an optical illusion caused by global warming. They also say that the sky color has changed: it’s now a whitish blue in the winter rather than a deep blue. In the wintertime up here, the sun doesn’t rise. But now the Inuit say the light is getting brighter in the winter. Again, the water vapor is diffracting the light in the atmosphere, making it seem lighter.

GO: What are your next steps after you return to the States?

WS: We have a lot of film from our expedition up here. We’ll be heading out to Los Angeles to start producing the documentary. In the summer, we’ll be back up to Baffin Island to do more interviews with the elders.

I’m also back on the global warming campaign trail in November, along with Fresh Energy, an energy policy organization with which I partner. We’ll be educating folks on solutions, specifically speaking a lot with congregations in the faith community.

Governor Tim Pawlenty appointed me to sit on Minnesota’s Climate Change Advisory Group. I’m working with about 50 other people from industry, environmental groups, local and tribal governments, transportation, and agriculture to develop a climate change action plan for the state.

I’ll also be working more with high school students, which I’m very excited about. They must feel empowered to fight this. They’re not taking on the challenge yet, but I think it’s going to happen soon, and I want to be part of it. I want to do now what we did 30 years ago during the Vietnam War; create a movement with young people. That’s when we’re going to see real change.
