A new selling point for renewable energy, courtesy of two former colonial powers

The New York Times’ front-page article on Portugal’s clean energy makeover is a must-read for anyone interested in sustainability. This warts-and-all profile of a small nation’s push to build a significant renewable energy economy is a big confidence booster if the sight of oil-soaked pelicans in the Gulf of Mexico has you down.

The short version is that Portugal and a handful of other small nations are way ahead in kicking the fossil fuel habit. Almost 45 percent of the electricity on Portugal’s national power grid is from renewable resources. Neighboring Spain, which recently opened a cutting-edge solar thermal plant, is having similar success to Portugal. Spain is expected to surpass every country except Portugal and Denmark for renewable energy production by 2025.

Spain and Portugal’s successes – and those of Denmark, Ireland, Iceland, Sweden, etc. – are helping renewable energy shake off a stubborn image consisting of high costs and low reliability. No, it hasn’t been a bed of organically grown roses in Portugal. Some Portuguese citizens have chafed at higher electric rates, but prices are expected to drop after the first generation of facilities is paid off. According to U.S.-based renewable energy consultant Alex Klein, however, the long-term benefits eclipse the short-term costs and extend way beyond economics. “The cost gap will close in the next decade, but what you get right away is an energy supply that is domestically controlled and safer,” Klein told the Times.

Now there’s a message that could even sell with the large swaths of the American public who don’t give a tinker’s damn about the environment – security. The more we rely on oil to power our economy, the less secure we are. Sarah Palin can chant “drill baby drill” until nuclear dawn, but the bald reality is that no amount of domestic drilling is going to get us off the imported oil crack pipe. The U.S. depends on other countries for 66 percent of our annual oil consumption. Every drop of oil under offshore waters or the Arctic National Wildlife refuge wouldn’t make a dent in that kind of demand.

Five, 10 or 20 years from now, when OPEC jacks up oil prices, or a military conflict cuts off the flow of Middle Eastern oil, who’s going to be more secure? The country that gets most of its energy from wind, solar, hydro and biomass, or the country with an IV line of tankers stretching across thousands of miles of ocean? Cue the Portuguese-accented laughter, please.

'Salt' plant and Duke study make solar outlook brighter

In Northern New England, where I live, the sun exists only in rumor and faint memory for weeks at a time. So when sustainable energy advocates talk solar, I think of my late-February pallor and mentally check out of the discussion. Long nights, short days of limited sun. Wind for my region maybe, but solar?

Well, yes, actually. Two news items that filtered through the excellent Inhabitat blog recently give hope to anyone who thinks the sun could help wean us off fossil fuels. The first comes from Sicily, where the energy company Enel recently fired up “Archimede” the world’s first utility-scale molten salt power plant. Archimede uses mirror concentrators to super-heat a molten salt solution circulating through a pipe array. The heat pipes power boilers that create steam to drive electrical turbines. The key to this system is that it can store energy for nights and cloudy days, much like the solar thermal systems I blogged about a while back. The combination of sodium nitrates and potassium salts in the system can accumulate heat for extended periods. That ability to ride out nights and cloudy days makes thermal solar more practical for sun-deprived areas like mine. Photovoltaic solar, the more widely known solar technology, generates electricity directly from the sun’s rays instead of through turbines. It’s most often associated with places like the American Southwest, which have weeks on end of uninterrupted sunshine.

But photovoltaic’s geographical limitations were never a technology problem, they were an economic problem. Solar panels work as well on a sunny New England day as they do on a sunny day anywhere else. They just didn’t work often enough to make them economically feasible because solar panels are expensive. Maybe not for much longer, though. Researchers at Duke University just released a study that says solar energy is now cheaper than nuclear energy, partly because the cost of panels is dropping. When it drops enough, it will be economically feasible to mount solar panels on rooftops to power air conditioners during hot summer days, or heat during clear, sunny winter days to reduce oil and coal consumption.

Now if I could just do something about that late February pallor …

Talking 'bout Co-g-g-generation

Posted At : June 2, 2010 10:54 AM | Posted By : Steve Hodgdon

Today’s blog is posted by guest blogger, Ed Marshall, a Senior Account Manager at Beaupre.

Before I read this story in the New York Times, it didn’t occur to me that milk and data centers would have much in common. In a nutshell, IT behemoth Hewlett Packard has calculated the biogas generated by manure from a 10,000 cow dairy operation could be harnessed to generate enough electricity to power a one megawatt data center.

“Information technology and manure have a symbiotic relationship,” said Chandrakant D. Patel, the director of H.P.’s sustainable information technology laboratory, which wrote the report.

And that’s the key word – symbiotic. The natural world is typically portrayed as a zero-sum competition for survival, red in tooth and claw. But in truth it’s equally true that the natural world is a story of highly efficient symbiotic, win-win arrangements – just like the dairy farm co-generation scheme.

From bacteria in our intestines to birds hanging out with crocodiles, natural systems are an ongoing lesson in symbiotic efficiency with nary a niche going unexploited. Human systems need to get more symbiotic. We've blogged before on increased efficiency perhaps being a more pressing near term need than alternate energy. Co-generation is a concept that seems a symbiotic natural.

The first Wiktionary definition of co-generation is “the production of heat and/or power from the waste energy of an industrial process.” The city of Aalborg, Denmark provides an example. An agreement with Aalborg Portland, the largest producer of ready-mixed concrete in Scandinavia, delivers surplus heat from the factory’s cement production process to the city’s district heating system (itself a great way to boost building heating efficiency, but that’s another post), providing heat for some 30,000 homes.

On this side of the Atlantic, our client Wheelabrator launched the first large-scale, commercially successful waste-to-energy project in the United States in 1975 providing an effective way to drive a new efficiency into the existing waste disposal process. Today Wheelabrator has five such plants generating almost 230 megawatts of electricity annually.

And co-generation can scale down to the business or even the individual home with technology that seems a closer fit to the second Wiktionary definition for cogeneration: “The simultaneous or serial production of heat and electricity from the same source”.

The world is facing hard choices about energy sources and usage. The efficiencies of co-generation present an opportunity to get more out of things we’re already doing – like walking, for instance.

Are we there yet? Time for energy efficiency to get its sexy on

Posted At : May 4, 2010 1:41 PM | Posted By : Steve Hodgdon

Today’s blog is posted by guest blogger, Ed Marshall, a Senior Account Manager at Beaupre.

How soon before we hit peak oil production? According to the U.S. military, it might be two years from now, or even less. If true, we’re well on our way to the real Energy Crisis. And the key to riding it out just might

be efficiency technologies like that itchy pink insulation in your attic.

Peak oil is the point when the world’s oil production reaches its highest rate and begins its inevitable decline, creating an oil deficit relative to demand.

That will happen globally in 2012 with “severe” shortfalls on world markets by 2015, according to a report issued by the United States Joint Forces Command. The UK’s Guardian newspaper covered it. Peak oil in the U.S. has already passed. It was 1970 for the lower 48 states.

So we just fill the gap with all kinds of renewable energy projects, right? Wrong.

It will take decades to spool up replacement technologies and attendant infrastructure. See, oil is a very energy dense and convenient source of power. Battery technology is a long way from matching oil’s energy density, and it has its own “peak” problems (lithium doesn’t exactly grown on trees). It will also need a materials-intensive charging infrastructure program to even begin propelling the millions of passenger cars currently on the road. Bio-fuels? Also not as energy-dense as petroleum, meaning you’d have to produce a hell of a lot more of it to replace a lesser volume of petroleum. Also, bio-fuels have a raft of production scaling issues that are, again, many years away from being addressed (let’s talk dry materials storage and handling!). Oh, and ethanol tends to pick up water easily and is fairly corrosive, so the existing gasoline pipeline transportation infrastructure isn’t well-suited to handling it.

Without a couple decades to work through these problems, we’d be better off focusing not on producing replacement fuels, but increasing efficiency – making the most of what’s at hand.

For instance, let’s tighten up our buildings. Buildings account for almost 50 percent of energy consumption in the U.S. (and a proportionate share of carbon emissions), according to the EIA. As we gin up those turbines, let’s be retrofitting the building sector – utilizing everything from smart glass like SAGE to advanced insulation materials and onsite combined heat units. And build this stuff into new construction.

Dare I suggest telecommuting? We’ve spent decades building a robust, intercontinental Internet. Surely it can handle remote workers, ecommerce and funny cat clips on YouTube.

Efficiency measures like these are in our collective DNA. A market-based economy is supposed to excel at efficiency and we’re generally good at it when we make the effort. Unfortunately, the easy availability of cheap energy has limited its appeal to date. Why insulate if heating oil is cheaper than Pepsi?

Back in December of 2009, President Obama unveiled a program of incentives to drive efficiency behaviors – and jobs – which subsequently became known as “cash for caulkers.” This passage from the linked article is telling:

"I know the idea may not be very glamorous, although I get really excited about it," Obama chuckled as he described the discussion at a roundtable on job creation he took part in just before his remarks. "Insulation is sexy stuff."

I agree, but for most folks, we’ll need to sex it up a bit, as the Brits say. There’s an image problem with energy efficiency. Ever since President Carter put on a sweater and went on national television in February of 1977 to say that we’d have to turn down the thermostat to build a better future, the concept of efficiency has been firmly wedded to that of sacrifice, rather than something sexier, like, say progress. Efficiency is a topic ripe for an extreme makeover.

So how, exactly, do we make energy efficiency sexy? More about that in my next post.

What if we could cool the planet?

Posted At : April 29, 2010 12:14 PM | Posted By : Steve McGrath
Related Categories: Cleantech,Commentary,Environment,Sustainable,Climate,Energy,Renewable Energy

Manmade carbon dioxide emissions are knitting a wooly blanket around the planet at a time when we really need to throw off the covers. Yet even if we could stop driving, manufacturing things and producing dirty power, it may be too late: climate scientists agree that without major intervention, existing CO2 will keep warming the planet for the rest of the century.

A potential solution is geoengineering, says Jeff Goodell, who appeared at RiverRun Bookstore Wednesday for his new book “How to Cool the Planet.” The Rolling Stone/New York Times Magazine contributor’s previous book is “Big Coal: The Dirty Secret Behind America's Energy Future” (2006).

We have the technology, he says. We can brighten clouds or blow tiny sulfur mirrors into the atmosphere to deflect sunlight from the earth’s surface. Deflecting 1 to 2 percent of sunlight would offset the warming effect of doubling today’s carbon emissions. We can also sequester CO2 by tossing iron in the ocean, thereby feeding plankton that will consume CO2 in photosynthesis and sink to the ocean floor. Oh, and there are tree-like machines that suck carbon from the air.

So how does this sound? Like a quick fix? Like Star Wars (the missile shield)? Like a threat to our spiritual integrity?

“Reaganesque,” said one young man in the audience, almost certainly born after the 40th president left office.

Goodell understands the anxiety. He’s conservation-minded himself and, in fact, headed to the Arctic Circle this weekend to better understand the warming threat. Geoengineering was “science fiction writ large” until he talked to enough smart people to conclude that we don’t have the luxury of being properly appalled. We’re staring down calamity.

Some of his conclusions:

Geoengineering is dangerous politically. A quick fix is precisely what some people like. As the ink on the book dried, he got a delighted call from the nation’s biggest fossil-fuel lobbyist. “We love your book!” Gulp.

Worse, geoengineering could enable rich individuals or states to act unilaterally to manipulate the climate. It’s like nuclear weapons: “How do you keep the crazy person’s finger off the trigger?”

Geoengineering will happen sooner or later. We’re in a position where we’ll have to consider this at some point, he says. We should start talking about it now.

Worse than technological hubris is human apathy. “The real risk is being fat dumb and stupid a lot longer and riding into this superheated world without any heed,” he says.

Ultimately, Goodell concludes that we are, like it or not, a species that manipulates our environment. Do you own an air conditioner? Do you like heat in the winter? He works another metaphor beautifully:

I’ve discovered that the people who understand this best are gardeners. I’m not much of a gardener myself, but I am married to one. My wife, Michele, is happiest when she has dirt under her fingernails, and one of her highest aspirations in life is to grow all our own food. It’s because of her that our kids have such a heightened sensitivity to the freshness of green beans that they can take one bite and tell you, with a good chance of being correct, whether the bean is store-bought or homegrown.

My wife’s garden is, by any standard, a product of human artifice. There is nothing “wild” about it, nothing undisturbed, nothing left alone. She has planted every plant and mixed the soil to her liking with imported alpaca manure. The garden is entirely organic – she’s no more likely to use Miracle-Gro than she is to dye her hair pink – but it is also entirely human. It is an artifact, but it is a living artifact. You do not walk through her vegetable garden and admire the basil and the asparagus an feel that nature has been banished.

Compelling thought indeed, but still, it’s just Goodell’s backyard.

I want to learn more. And as a professional communicator, I’m eager to see how geoengineering alights on our national radar screen. I cringe at the possibility (certainty?) that politicians and pundits will get hold of this and club one another silly with it, as with health care. And despite my status as a card-carrying independent, the possibility (certainty?) of the profit motive getting further entangled with the fate of the planet concerns me.

Can we start a conversation on geoengineering? Should we start one? If so, how?

Let us know what you think.

Getting off the grid and into green biz: one man's story

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. USA Solar Store - http://www.usasolarstore.com/solar/ - Dave Bonta

USA Solar Store - http://www.usasolarstore.com/solar/ - Dave Bonta

“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.”

A new generation of products wraps stodgy concept of conservation in sexy new clothes

Covalent’s organic solar concentrator - www.covalent.com

Covalent's organic solar concentrator

Not too long ago I described conservation and efficiency as the homely sisters in the sustainable energy world because there were no iconic products that symbolize efficiency the way wind farms and solar panels symbolize their respective industries. I was wrong. Epically wrong.

The U.S. Department of Energy recently published a list of companies that received grants to develop energy efficiency technologies. Many of these products are relatively boring, designed to toil away deep in the bowels of a power generation system, squeezing out delivering a few more watts here and a few more degrees there. Others, though, really capture the imagination. They show that energy efficiency doesn’t have to be a dud in the public eye. It can excite the popular imagination and communicate the message that using less energy is the single nicest thing you can do for the Earth until renewable energy usurps fossil fuels. And some of these efficiency products are, if you’ll grant some latitude on the use of the word, sexy.

Take Nanotrons, a division of Agiltron. Nanotron is working on a long-lasting reflective coating to improve on today’s short-lived coatings. Paint Nanotron’s coating on your building’s roof, then watch your cooling costs drop. Kazak Composites is developing building panels that retain heat and coolness, and “know” when to release them to keep room temperatures even. Lower air conditioning bills in a can? Smart sheetrock? Not bad.

Even the stuff that will work under the covers has a good cool quotient. Machflow Energy, for example, is using exotic gases like krypton and xenon in a heat pump that makes refrigerators, freezers and air conditioners run on less electricity and with no environmental damage. Considering that heating and cooling systems emit over a half billion tons of carbon dioxide into the atmosphere each year, according to the DOE, efficiency improvements make a huge difference to the environment. And you thought krypton was Superman’s home planet and xenon was the warrior princess’ brother.

Some products combine efficiency with one of the other marquee sustainable energy sources. Covalent Solar is developing coated glass that improves solar voltaic efficiency by concentrating solar energy on dense arrays of solar cells at the edges of the glass, reducing the overall number of cells needed to produce the same amount of power as a larger solar array. Giner Electrochemical Systems, LLC., is working on a new way to produce hydrogen (fuel cells, anyone?) with less electricity than current production methods.

So back to the use of “sexy.” Maybe “interesting” or “fascinating” would have been more appropriate words to describe these up-and-coming efficiency technologies, but they lack the necessary sizzle. Energy efficiency needs to be in the public’s face – and not just the “earth first” set. They’re already invested. I’m talking rank-and-file consumers. The U.S. consumer market consists of more than 100 million households and generates about 17 percent of the nation’s greenhouse gas emissions, according to EnergyStar.gov. As much as 30 percent of the energy used to power household heating, cooling and appliances is wasted. The European Union is ahead of the U.S. on the efficiency front. It has already set a goal of cutting its energy consumption 20 percent by 2020, and it knows it needs the mass audience’s buy-in to reach that goal. “To achieve this goal, it is working to mobilize public opinion, decision-makers and market operators and to set minimum energy efficiency standards and rules on labeling for products, services and infrastructure,” the European Energy Agency writes on its Web site. We’re not going to make worldwide societal changes that reduce energy consumption by talking like Mr. Spock. Efficiency needs an iconic product that combines a little Angelina Jolie sex appeal with some Steve Jobs salesmanship thrown in for good measure.

Cuttyhunk says 'YIMBY' to wind power

Posted At : December 22, 2009 2:57 PM | Posted By : Steve McGrath
Related Categories: Cleantech,News,Renewable Energy,Sustainable,Electricity,Energy,Wind,Green

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 nobats 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.”

Real Christmas trees are okay

Posted At : December 8, 2009 9:18 AM | Posted By : Steve McGrath
Related Categories: Green,Commentary,Sustainable

The verdict is in: It's okay to have a real Christmas tree – yes, the kind you cut down.

That’s according to the National Christmas Tree Association and my informal Yammer, Facebook and Twitter poll on tree choice. The breakdown:

Real tree: 74 percent

Fake: 15 percent

No tree: 11 percent

Although the poll was about respondents’ outright choice, many commented on the sustainability considerations. Lest you think the survey too lightweight, know that some heavy hitters took part.

A prominent New England horticulturalist:

“Buying locally grown trees help keep farms/crops alive. I like to make ornaments that the birds can enjoy and put the tree outside my window after the holidays to extend its life.”

A forester for the U.S. government:

“If you buy from a local grower, you are helping to preserve open space – the loss of which is arguably one of our most pressing environmental concerns in the Northeast. The grower is making a modest profit (compared to growing condos).”

The NCTA asserts that artificial trees contain dangerous chemicals, are imported all the way from China, and consume natural resources of their own in their manufacture.

The joy of real

In addition to the green benefits, many poll respondents prize the tradition, the scent, and the sheer joy (especially for kids) of having a real Christmas tree. Several mentioned felling it themselves and recycling it afterwards. Approximately 25-30 million real Christmas trees are sold in the U.S. every year, according to the National Christmas Tree Association (more stats).

Four of the 27 respondents to my poll prefer manufactured trees, yet only one does it for environmental reasons.

“We don’t like cutting a fresh tree every year. We figure one batch of plastic re-used for 20 years beats 20 trees on the environmental scale.”

The American Christmas Tree Association, not to be confused with the aforementioned National Christmas Tree Association, agrees with this position, saying that over a 10-year span, the carbon footprint of one artificial tree is smaller than consuming 10 real ones. Moreover, it says, the PVC in artificial trees is safe enough for water pipes and plastic wrap.

For real-tree advocates, however, the Tannenbaum is the soul of Christmas, and it shouldn’t come from Wal-Mart. It’s one of the last vestiges of real in a holiday dominated by electronics, licensed characters, parking lot wars, Manheim Steamroller and pathological consumption. For them, a real tree promises a real Christmas. So it’s good to hear that real trees are at least green enough for people wanting to do right by the environment.

What kind of tree are you getting? Post a comment explaining why.
