Energy Secretary Steven Chu begins big energy efficiency push (Treehugger)
In a recent news release for a cleantech client I struggled to quantify the energy savings and environmental impact that the technology delivered in a meaningful way. Communicating clean energy benefits can often trigger a mish-mash of metrics, like energy units (e.g. kilowatts/hour) made, dollars saved or potential pollutants scrubbed from the atmosphere.
To that end, Scientific American introduces us to a new scientific measurement for energy savings called the “Rosenfeld” named after the so-called “godfather of energy efficiency,” Scientist Arthur Rosenfeld.
One Rosenfeld equals an energy savings of 3 billion kilowatt-hours per year — the same amount generated by a 500-megawatt coal-run power plant. As Scientific American describes it, the Rosenfeld metric provides a much needed:
“… measurement that would help regular people visualize efficiency’s massive potential, but also be as accurate as possible.”
Weight Watchers have calories, cars have MPG and my woodstove boasts in BTUs. It’s not a bad idea that communications pros in clean tech industries coalesce around a standard, meaningful unit of energy savings measurement. And while we’re at, let’s nickname it the Rosy for simplicity’s sake.
This morning Department of Energy (DOE) Secretary Steven Chu – joined by Senators Al Franken and Amy Klobuchar – announced $100+ million in DOE funding and IRS green manufacturing tax credits for our client SAGE Electrochromics.
These funds will help SAGE establish a new 250,000 sq. ft. facility in Faribault, Minnesota used to manufacture energy-saving, electronically tintable dynamic glass that makes buildings more energy efficient and creates hundreds of new, skilled, green manufacturing jobs.
While hundreds of buildings have already installed SageGlass windows, this new government funding will enable the company to mass produce its glass and bring this energy saving technology to the world.
Secretary Chu has repeatedly said the biggest gains in decreasing this country’s energy bill, the amount of carbon dioxide and our dependency on foreign oil will come from energy efficiency and conservation in the next 20 years. SageGlass is a leading example of an energy efficiency technology.
SageGlass products transform windows from an energy liability to an energy source. The potential for energy savings is significant because energy loss through windows accounts for about 30% of heating and cooling energy. According to the National Renewable Energy Laboratory (NREL), electrochromic windows like those produced by SAGE can save one-eighth of all the energy used by U.S. buildings each year. This is equivalent to about 5% of the nation’s energy budget. This translates into savings of approximately $300 billion over the next 20 years.
That’s not chump change.
SAGE focused on something each of us experiences every day – glass – and re-imagined it, transforming glass into something innovative that helps make the world a better place and America more competitive.
This is a great example of how something seemingly mundane like a window can become highly transformational.
Marketers for smart grid products have had it rough because it’s like trying to sell a movie without a story line. Few people outside the energy industry have a clue as to how the smart grid will work. Unresolved standards keep us from knowing what it will be made out of. And the smart grid’s promise of energy efficiency and cleaner air have been unsubstantiated guesses at best.
But on this last point, smart grid marketers now have a reason to smile. The U.S. Department of Energy has done the math and has finally wrapped some great numbers around smart grid efficiencies, providing much-needed fuel for the marketing machine.
According to a new DOE report, the smart grid will enable us to cut energy consumption by 12% by 2030, and cut carbon emissions from power plants by the same amount.
Smart grid marketers can now crisply message around how they’re going to reduce your electric bill while also greening the planet.
But for the message to stick, they also have to tackle the other fore mentioned obstacles by scrubbing the unnecessary technobabble from smart grid conversations. Today, smart grid marketers trumpet things like Advanced Metering Infrastructure (AMI), peak-load demand response and home area networks (HANs). These terms are fine for B2B sales and marketing within the energy industry. But to create the consumer pull-demand that could accelerate smart grid deployments, marketers will need to create a new consumer-friendly lexicon.
Dave Bonta hasn’t paid an electric bill in 12 years. He has no heating bill, either.
That’s because he kicked his 40 kilowatt/hr electricity habit in the 1990s and used solar electricity to fill the gap. “I learned to live on less,” he told an audience at RiverRun bookstore the other night. “Surprise, I made it to one kilowatt. It wasn’t hard…. It’s kind of nice to think we can throw our electric bills away. It’s kind of empowering.”
To reduce his power usage, Bonta – who has since co-authored the “The New Solar Home” and created the USA Solar Store chain – replaced light bulbs, got an energy-efficient washing machine, switched from a vacuum cleaner to a broom, and tossed the electric toothbrushes. “Anything that could be done with human power we did.” Even the press he used in his printing business was human-powered. He pedaled it.
Once he’d shrunk his energy footprint, he installed a small-scale solar electricity system in his rustic Vermont home. Printing customers immediately peppered him with questions about his set-up. That’s when the light bulb went off. He could sell this stuff, along with the know-how. Which is exactly what USA Solar Stores do, and the chain now has 27 stores in 11 states. It’s “about to grow like wildfire,” he says earnestly.
Bonta models his stores after the crunchy old Gateway stores, where the PCs were displayed on barnboard tables and salespeople didn’t bug you till you had a question. At USA Solar Stores, you can get anything from a conversation to a compact fluorescent light bulb to a full-fledged solar electricity setup. Or you can come in, look and leave. No worries. In any case, Bonta’s team is eager to address what he calls the three solar bogey men: expense, viability, aesthetics.
Bogey Man #1: Solar electricity is too expensive. Bonta will look at your current electric bill, figure in current incentives, find ways to reduce your demand, and show you how long it will take to pay off your gear. Even if the incentives disappear, he says, it’s still a good deal. The joy of sticking it to the man? Priceless.
Bogey Man #2: It doesn’t work too well. Wrong, he says.There’s a myth that if you wait, solar technology will get less expensive and super technology will come along. “The way it is now is pretty good. The technology is there, and the only thing missing is people who will try it.”
Bogey Man #3: It’s ugly. No, Bonta says, solar is becoming increasingly “building integrated” – where it’s embedded in your roof, not tacked on like an afterthought. And you don’t need it on your house at all. Bonta’s panels are on his shed, which gets better light anyway. The homes in his book are of jaw-dropping beauty.
Bonta is a softspoken guy. Although he has the conviction of a preacher, he has the slickness of, well, the guy who melted down in his first speech to the Rotary. But in the bookstore, once he warmed up you could tell he will not be denied: “Everything we can do to get our country on a sustainable path, we’re going to do.” If not, he says, generations will hold us accountable for the demise of the world’s ecology. “We can either explain it to them from a wheelchair, or fix it now.”
The scribes at here at CleanSpeak central have written about everything from wind, to solar, to endangered natural landscapes, to endangered McMansions, to Christmas trees, to hybrid vehicles this year. We decided to take a look back and nominate our own slate of candidates for the Top 5 Environmental Stories of 2009.
The American Recovery and Reinvestment Act of 2009. It included $80 billion for green/sustainable initiatives like a smart power grid, renewable energy technology, home heating efficiency and green job training programs. If the American economy is going to be more sustainable, it’s going to take this kind of government leadership.There were, of course, innumerable other environmentally tinged stories this year. Any thoughts on what should have made the list? Let us know!
Unlike the new NIMBYs, selectmen in the town encompassing Massachusetts’ Cuttyhunk Island say they will support a wind farm off their shores, a position directly at odds with many of their neighbors to the immediate east on Martha’s Vineyard.
Residents seem to back the decision:
“I don’t think you can just say, ‘Not in my backyard,’ and expect that will be OK,’’ said resident Nina Brodeur. “If I had my preference, I’d choose not to see them. But I understand the needs of the state, and if it’s not in my backyard, it would have to be in somebody else’s. We can’t close our eyes and think we’re more special than anyone else.’’
At issue is Cape Wind, the embattled wind farm proposed for Nantucket Sound. Opponents say the landmark project will be a blight on the horizon and ruin a historic Native American site. The project also help Cuttyhunk residents, as part of Massachusetts’ poorest community, pay their utilities:
“I think the wind farm is a great idea,’’ said George Isabel, 59, who has lived on Cuttyhunk since 1968 and serves as police chief and harbor master. “People here can’t afford to turn on their air conditioners or electric heat. Something has to give, because it’s hard to survive. There could be big benefits for us.’’ (Source: Boston Globe)
Maine may be next for offshore wind. The state just announced three offshore wind test sites.
A couple other developments in the wind arena:
Endangered bat concerns stall another wind farm
A West Virginia judge just halted progress of an Appalachian ridgeline wind farm because the developer failed to account for endangered Indiana bats on the property. Developers don’t have to prove that no bats will die in the project, just that the damage – presumably from construction, displacement and/or turbine blades – is minimized. That means potentially years of surveying, planning and permits. Plaintiffs in the case said the project would kill 6,746 bats of all kinds annually. Source: New York Times.
Report: Turbines are annoying, perhaps, but not sickening
An expert panel issued a report this month questioning the validity of wind-turbine syndrome, the constellation of symptoms – including sleep problems, headaches, dizziness, anxiety, ringing in the ears – sometimes associated with turbine noise.
“There is no evidence that the audible or sub-audible sounds emitted by wind turbines have any direct adverse physiological effects,” says the report, prepared by a multidisciplinary panel of medical doctors, audiologists, and acoustical professionals for the American and Canadian wind energy industry associations. The 85-page document does admit that turbine noise can be annoying.
“An annoyance factor to wind turbine sounds undoubtedly exists, to which there is a great deal of individual variability. Stress has multiple causes and is additive. Associated stress from annoyance, exacerbated by the rhetoric, fears, and negative publicity generated by the wind turbine controversy, may contribute to the reported symptoms described by some people living near rural wind turbines.”

Did you ever expect to find cutting-edge renewable energy technology in your grammar school lunch box? Right there, next to your PB&J and a slightly bruised apple most likely sat a thermos bottle of milk or soup. That bottle worked on the same basic principle as solar thermal technology, the most practical renewable energy source for regions without the right weather to support today’s marquee renewables – wind power and solar photovoltaic. Which would be much of the continental U.S.
Unlike photovoltaic and wind systems, solar thermal systems can store energy for use at night or on cloudy, windless days. Photo thermal systems are like huge thermos bottles that use sunlight to super-heat highly concentrated salt solutions. Insulated “bottles” trap the heat. When the wind doesn’t blow or the sun doesn’t shine, the trapped heat can generate steam to produce electricity or heat water to warm homes and businesses. Spain is starting work on a large-scale solar thermal plant for its Seville province in 2010.
Regions like New England, the Mid Atlantic and the Pacific Northwest could go Spain one better by combining solar thermal, wind and photovoltaic in one super-renewable energy system. We here in New England get wind, but not the steady, predicable wind that makes the Great Plains states ideal for wind power. We get sun, but not enough for large-scale solar, like the Southwest. So here’s an idea for the renewable-poor states. Build wind turbine farms for when the wind blows. Build photovoltaic arrays for when the sun shines. But don’t hook them up directly to the grid, use them to generate and store heat in solar thermal systems to match energy production with energy demand. What do you think? Practical, or a crackpot idea?
