President Obama Sets New Energy Policy – Well sorta

President Obama announced his new Energy Policy for the second half of his first term. This is a lot to get done in 2 years. We shall see how it goes. With gasoline prices hovering around or above  4  $$$ a gallon, maybe he will get some movement on the fleet transportation issues.

Introduction: Blueprint for a Secure Energy Future
“We cannot keep going from shock to trance on the issue of energy security, rushing to propose action when gas prices rise, then hitting the snooze button when they fall again. The United States of America cannot afford to bet our long-term prosperity and security on a resource that will eventually run out. Not anymore. Not when the cost to our economy, our country, and our planet is so high. Not when your generation needs us to get this right. It is time to do what we can to secure our energy future.”

President Obama, March 30, 2011
Rising prices at the pump affect everybody – workers and farmers; truck drivers and restaurant owners. Businesses see it impact their bottom line. Families feel the pinch when they fill up their tank. For Americans already struggling to get by, it makes life that much harder. Demand for oil in countries like China and India is only growing, and the price of oil will continue to rise with it. That’s why we need to make ourselves more secure and control our energy future by harnessing all of the resources that we have available and embracing a diverse energy portfolio.
Every president since Richard Nixon has called for America’s independence from oil, but Washington gridlock has prevented action again and again. If we want to create a more secure energy future, and protect consumers at the pump, that has to change. When President Obama took office, America imported 11 million barrels of oil a day. Today, he pledged that by a little more than a decade from now, we will have cut that by one-third, and put forward a plan to secure America’s energy future by producing more oil at home and reducing our dependence on oil by leveraging cleaner, alternative fuels and greater efficiency.
We’ve already made progress toward this goal – last year, America produced more oil than we had in the last seven years. We’re taking steps to encourage more offshore oil exploration and production – as long as it’s safe and responsible. And, because we know we can’t just drill our way out of our energy challenge, we’re reducing our dependence on oil by increasing our production of natural gas and biofuels, and increasing our fuel efficiency. Last year, we announced ground-breaking fuel efficiency standards for cars and trucks that will save consumers thousands of dollars and conserve 1.8 billion barrels of oil.
And beyond our efforts to reduce our dependence on oil, we must focus on expanding cleaner sources of electricity, including renewables like wind and solar, as well as clean coal, natural gas, and nuclear power – keeping America on the cutting edge of clean energy technology so that we can build a 21st century clean energy economy and win the future.
To help us reach these goals, the Blueprint for a Secure Energy Future outlines a three-part strategy:

Develop and Secure America’s Energy Supplies: We need to deploy American assets, innovation, and technology so that we can safely and responsibly develop more energy here at home and be a leader in the global energy economy.
Provide Consumers With Choices to Reduce Costs and Save Energy: Volatile gasoline prices reinforce the need for innovation that will make it easier and more affordable for consumers to buy more advanced and fuel-efficient vehicles, use alternative means of transportation, weatherize their homes and workplaces, and in doing so, save money and protect the environment. These measures help families’ pocketbooks, reduce our dependence on finite energy sources and help create jobs here in the United States.
Innovate our Way to a Clean Energy Future: Leading the world in clean energy is critical to strengthening the American economy and winning the future. We can get there by creating markets for innovative clean technologies that are ready to deploy, and by funding cutting-edge research to produce the next generation of technologies. And as new, better, and more efficient technologies hit the market, the Federal government needs to put words into action and lead by example.
What follows is a roadmap that aims to distill some of the challenges at hand, and to outline strategies for surmounting those challenges that build on the strong record of what the Obama Administration has already accomplished and set in motion.

Wind Power Blows – So this is the alternative energy Presidency

You think it has been a bad year for nuclear power or Japanese grown vegetables?

http://www.frontlinestocks.com/hrte/

Wind energy declines in USA

28 July 2010

Wind power installations to date this year have dropped by 71% from last years level, according to the latest quarterly report from the American Wind Energy Association (AWEA).

Only 700 MW of wind turbines were added in Q2 2010, down 57% from comparable 2008 levels and down 71% from 2009.

Even with 5.5 GW of wind power under construction and a more active second half of the year anticipated, AWEA projects that total 2010 installations will be 25% to 45% below 2009 installations, depending on policy developments.

Combined Q1 and Q2wind energy installations in 2010 are 1239 MW, 57% below 2008 half-year levels and 71% below 2009.

AWEA and a coalition of renewable energy, labor, utility and environmental groups are calling on the US Congress to enact a strong national renewable electricity standard (RES) to spur demand for green power, attract manufacturing investment and save (and create) jobs.

“Strong Federal policy supporting the US wind energy industry has never been more important,” says Denise Bode of AWEA. “We have an historic opportunity to build a major new manufacturing industry.”

“Without strong, supportive policy like an RES to spur demand, investment and jobs, manufacturing facilities will go idle and lay off workers if Congress doesn’t act now – before time runs out this session,” she adds.

US wind energy now in ‘coasting momentum’

There is no demand beyond the present “coasting momentum” and, without stable policy, without demand and new power purchase agreements and without new wind turbine orders, the domestic industry is sputtering out, the group notes. “Passage of a strong national RES will boost demand and fire up the industry’s economic engines.”

The US wind energy industry has repeatedly criticized the ‘boom-and-bust’ cycles which result in layoffs and also discourage investment in new manufacturing facilities. The USA is losing the clean energy manufacturing race to Europe and China, which have firm long-term renewable energy targets and policy commitments in place, warns AWEA.

According to a national poll conducted by Public Opinion Strategies, an RES is popular among US voters with strong support from 65% of Republican voters, 69% of Independents and 92% of Democrats.

GENEVA, SWITZERLAND — 28 February 2011 — Cargill has signed an agreement with SkySails GmbH & Co. KG (SkySails) to use wind power technology to reduce greenhouse gas emissions in the shipping industry. SkySails, based in Hamburg, has developed innovative, patented technology that uses a kite which flies ahead of the vessel and generates enough propulsion to reduce consumption of bunker fuel by up to 35 percent in ideal sailing conditions.

Next December Cargill will install the 320m2 kite on a handysize vessel of between 25,000 and 30,000 deadweight tonnes, which the company has on long-term charter, making it the largest vessel propelled by a kite in the world. Cargill and SkySails aim to have the system fully operational in the first quarter of 2012. Cargill is currently helping SkySails develop and test the technology and has identified a ship-owner – supportive of environmental stewardship in the industry – with whom it will partner on the project.

The SkySails kite will be connected to the ship by rope and is computer-controlled by an automatic pod to maximise the wind benefits. The kite functions at a height of between 100 to 420 metres and flies in a figure of eight formation. The SkySails system is automated and requires only minimal action by the crew. An automatic control system steers the kite and adjusts its flight path. All information related to the system’s operation is displayed on the monitor of the SkySails’ workstation on the ship’s bridge.

“For some time, we have been searching for a project that can help drive environmental best practice within the shipping industry and see this as a meaningful first step”, said G.J. van den Akker, head of Cargill’s ocean transportation business. “The shipping industry currently supports 90 percent of the world’s international physical trade. In a world of finite resources, environmental stewardship makes good business sense. As one of the world’s largest charterers of dry bulk freight, we take this commitment extremely seriously. In addition to lowering greenhouse gas emissions, the SkySails technology aims to significantly reduce fuel consumption and costs. We are very impressed with the technology and see its installation on one of our chartered ships as the first part of an ongoing, long-term partnership.”

“We are delighted that Cargill is the first company to embrace our technology on a vessel this large as part of its commitment to help reduce greenhouse gas emissions in the shipping industry”, said Stephan Wrage, managing director of SkySails. “We are excited that our technology will shortly be used on a handysize vessel for the first time and see great potential to incorporate it on larger ships in the future.”

According to a United Nations (International Maritime Organisation) study, up to 100 million tonnes of carbon dioxide (CO2) could be saved every year by the broad application of the SkySails’ technology on the world merchant fleet.1 This figure would equate to 11 percent of the CO2 emissions of Germany.

Cargill is a significant global transporter of agricultural, energy and industrial commodities. Although the company does not today own or operate ships, its ocean transportation business ships more than 185 million tonnes of commodities each year, in the process connecting supply from areas of surplus with demand in areas of deficit.

Wind Offshore When – Maybe soon, maybe manana

This has an interesting storage system however so read the rest of the article.

http://www.green-energy-news.com/arch/nrgs2011/20110012.html

February 13, 2011 – Vol.15 No.48

OFFSHORE WIND ENERGY MEETS OFFSHORE WIND ENERGY STORAGE.
by Bruce Mulliken, Green Energy News

Eventually the United States will get its first offshore wind farm. No one is taking bets as to when it will go online. There have been many proposals, but so far resistance onshore has kept those projects from being built.

Still, wind resources are much better offshore than on and those windy resources are often near heavily populated areas that will be able and willing to consume electricity generated by those reliable ocean breezes.

As with many relatively expensive technologies it’s not such a bad thing to be a late adopter. Early adopters make and have to correct mistakes at a high cost. Early adopters too have only earliest versions of the technology to work with. Late adopters, on the other hand, learn from the mistakes of early adopters and need not repeat them. Late adopters also get to use newer, more sophisticated versions of the technology in question.

Offshore wind is one of those relatively expensive technologies that it’s OK to be a late adopter.

When U.S. offshore wind builders finally get around to planting the first turbine in the ocean bottom (or perhaps floating turbines in deep water over the horizon) they’ll have a better idea of the costs, know exactly how to install them and they’ll have access to far more powerful turbines than those used in the first offshore wind farms in Europe. The U.S. will benefit by being slow to adopt offshore wind, but the time has come to embrace the technology; wind developers know this, so does the U.S. government.

Even as dollars are being pinched in Washington, the Department of Energy has put aside $50.5 million for projects that support offshore wind energy development. The Department of the Interior too, in its Smart for the Start program, has given a hand to offshore wind development by designating four areas along the Mid-Atlantic coast to be on the fast track for regulatory approval.

The funding being offered by DOE can be used for the development of innovative wind turbine design tools and hardware to provide the foundation for a cost-competitive and world-class offshore wind industry in the United States (up to $25 million over 5 years); for baseline studies and targeted environmental research to characterize key industry sectors and factors limiting the deployment of offshore wind ( up to $18 million over 3 years); and for the development and refinement of next-generation designs for wind turbine drivetrains (up to $7.5 million over 3 years).

The Department of the Interior has chosen areas on the Outer Continental Shelf offshore Delaware (122 square nautical miles), Maryland (207), New Jersey (417), and Virginia (165) to receive early environmental reviews that will help to lessen the time required for review, leasing and approval of offshore wind turbine facilities.

Government isn’t alone in seeking to develop offshore wind.

“There are no technological or economic barriers to converting the entire world to clean, renewable energy sources,”

Researchers: 100 Percent Green Energy Possible By 2050

We approach energy policy with care here, since GreenCarReports is largely about … well, cars.

But a recent article claims it could take just 40 years to convert the bulk of the world’s global energy usage from fossil fuels to renewable energy, primarily wind and solar power.

That’s not only vehicle fuel, but also electric-power generation, home heating, and the many other global activities that rely on the remarkably high energy density of the hydrocarbon molecules in coal, oil, and natural gas.

Researchers from Stanford University and the University of California-Davis published their analysis in the journal Energy Policy.

Measuring costs vs benefits

The main challenges, say the authors, will be summoning the global will to make the conversion. “There are no technological or economic barriers to converting the entire world to clean, renewable energy sources,” said author Mark Jacobson, a Stanford professor, saying it is only a question of “whether we have the societal and political will.”

Another challenge: accurately accounting for both the costs (which are comparatively easy to tally and project) and the benefits (which are tougher).

When looking at the cost of junking half a century’s worth of existing power plants, for example, how can electric utilities benefit from the tens of billions of dollars in public health costs that will be avoided in the future once those emissions are no longer being generated?

Those public-health benefits might include saving 2.5 to 3 million lives each year.

And then there’s the benefit of halting climate change, not to mention reductions in water pollution, and increased energy security as more of each nation’s energy is generated from within its own borders.

Step One: New generation from renewables

The authors assessed the costs, benefits, and materials requirements necessary to convert the bulk of the world’s energy usage to renewable sources.

Just as it will do over the next few decades for cars, electricity will play an increasingly large role, with 90 percent from wind turbines and various forms of solar generation.

Hydroelectric and geothermal sources would each provide about 4 percent of the total, with another 2 percent from wave and tidal power.

Vehicles would run either on electricity provided by the power grid, or hydrogen stored under high pressure and converted to electricity in a fuel cell. Airplanes would be fueled with liquid hydrogen. But, crucially, the hydrogen would all be produced electrically, with the electricity coming from those same renewable sources: wind, sun, and water.

The analysis shows that the land and raw materials needed won’t pose a problem. What will be needed is a much more robust electrical grid.

Paul Krugman: Colorless Green Ideas

Now that the scientific debate over global warming is all but over, Paul Krugman looks at what we can do limit greenhouse gas emissions:

Colorless Green Ideas, by Paul Krugman, Commentary, NY Times: The factual debate about whether global warming is real is, or at least should be, over. The question now is what to do about it.

Aside from a few dead-enders on the political right, climate change skeptics seem to be making a seamless transition from denial to fatalism. In the past, they rejected the science. Now, with the scientific evidence pretty much irrefutable, they insist that it doesn’t matter because any serious attempt to curb greenhouse gas emissions is politically and economically impossible.

Behind this claim lies the assumption, … that any substantial cut in energy use would require a drastic change in the way we live. To be fair, some people in the conservation movement seem to share that assumption.

But the assumption is false. Let me tell you about … an advanced economy that has managed to combine rising living standards with a substantial decline in per capita energy consumption, and managed to keep total carbon dioxide emissions more or less flat for two decades, even as both its economy and its population grew rapidly. And it achieved all this without fundamentally changing a lifestyle centered on automobiles and single-family houses.

The name of the economy? California.

There’s nothing heroic about California’s energy policy… [T]he state has adopted … conservation measures that are … the kind of drab, colorless stuff that excites only real policy wonks. Yet the cumulative effect has been impressive…

The energy divergence between California and the rest of the United States dates from the 1970s. Both the nation and the state initially engaged in significant energy conservation after that decade’s energy crisis. But conservation in most of America soon stalled…

In California, by contrast, the state continued to push policies designed to encourage conservation, especially of electricity. And these policies worked.

People in California have always used a bit less energy … because of the mild climate. But the difference has grown much larger since the 1970s. Today, the average Californian uses about a third less total energy than the average American, uses less than 60 percent as much electricity, and … emit[s] only about 55 percent as much carbon dioxide.

How did the state do it? In some cases conservation was mandated directly, through energy efficiency standards for appliances and rules governing new construction. Also, regulated power companies were given new incentives to promote conservation…

Neil Steinberg And Energy Policy -New Technologies bring new complaints

The internet can be such a frustrating place. I thought that because I had put up about 15 right wing pundits views about energy policy that I should put up some left wings views as well. So I searched for something like “10 most left wing journalists” in America and I came up with this site.

http://www.renewamerica.com/columns/huston/100723

Now this piece listed number two and I had to futz around to find number 10 which he listed as Neil Steinberg who works for the Chicago Sun Times which is of course here.

http://www.suntimes.com

I googled up Neil Steinberg for energy policy and found a great article by him but it was filed as a PDF file in a Wisconsin Utility hearing docket. I can’t copy a PDF file and I always like to give original citings but I could only find a weird copy of it in a weird place so here it is. It was originally titled:

Winds of change inevitably get the hot air stirring

and was dated April 10th. The text is not credited here:

Progress never comes without complaint. Everybody wants perfect cell phone service — there are more than 4 billion cell phones worldwide, two for every three people — but nobody wants a cell tower near them. Earlier this month in rural Maryland, neighbors turned out to protest the zoning variance needed to put a cell tower on farmland, even though most would barely see the top of the tower if it went up. “We will be fighting it every step of the way,” one said. Of course they will. People still fight cell towers, just as they fight skateboard parks, mosques, research centers, halfway houses — almost anything new and nearby. They no longer complain about streetlights — but they once did. More about that later. Not in my ocean. Naturally, the rich folk living on Cape Cod opposed the idea of a wind farm off Nantucket. When gazing out to sea, reflecting on the splendor of their lives, they might see the turbines and be vexed. So it is a minor miracle that the federal government decided to go ahead with Cape Wind anyway, after only nine years of study and discussion. “This is the final decision of the United States of America,” Interior Secretary Ken Salazar announced this week. Needless to say, that was “Gentlemen, start your lawsuits,” to those aghast at the idea of seeing 130 giant white turbines on the horizon.Instead of discussing the nation’s overdependence on foreign oil, and the bad things that flow from it — from increased terrorism to global warming — I will tip my hand: I think wind turbines are beautiful. I first saw some, unexpectedly, out an airplane window while landing in Copenhagen a few years back — the Middelgrunden Wind Park, 20 turbines in the sound between Denmark and Sweden. It was a stunning sight, and even more stunning to learn that they provide 4 percent of the electricity consumed by Copenhagen. Denmark derives 20 percent of its electrical power from the wind. Meanwhile, the United States, once a world leader in technology and not without windy places, generates only about 0.8 percent of its electricity from wind power. Last summer, driving through Minnesota, the boys and I were surprised and delighted by the huge wind turbines flanking the highway. Yes, passing by something is not the same as living next to it. But if what people wanted next door were the deciding factor in history, we’d still be churning butter with a stick (you might think, “Yes, I’d love that!” but then you aren’t considering that half your children eating that butter would have died of whooping cough before age 2 — you can’t reject progress for its ills while thoughtlessly accepting all the good). Denmark, Minnesota and Cape Cod are windy places. Chicago is also a windy place, and to our credit, Mayor Daley at least says he is open to the idea of turbines in Lake Michigan. Evanston is considering them as well. Heck, why not — we already have to look at Gary on a clear day.’Cold, unlovely, blinding star’Once upon a time people believed in the future. Their lives were hard, and they accepted inconveniences if they thought things might improve in the long run. That didn’t mean they weren’t frightened or they didn’t complain.When opponents of Cape Wind worry that the wind turbines will kill migrating birds, destroy tourism, imperil navigation, whatever, we have to remember that every technological development in the history of the world has been met by a chorus of concern. Take the simplest advance — gas lamps on public streets — something we look upon now with only nostalgia and affection. Not so when new.” An attempt to interfere with the divine plan of the world, which has preordained darkness during the night-time,” a newspaper in Cologne fretted in 1816, after that city installed gaslight. Electric lighting brought even more revulsion.” Horrible, unearthly, obnoxious to the human eye,” Robert Louis Stevenson wrote of London’s new electric light. “A lamp for a nightmare!” . Casting illumination upon a city’s nighttime doings would be, he said, “a horror to heighten horror.”Arc lighting at Paddington Station moved the St. James Gazette to protest in verse: Twinkle, twinkly little arc,Sickly, blue uncertain spark; Up above my head you swing, Ugly, strange expensive thing! In America, we despaired at what the unleashing of all this electricity might mean. The constant electric light would cause blindness, or “photo-electric ophthalmia. ” The demon of electricity surging around helter-skelter would change the weather. “All the floods, hurricanes, cyclones and other atmospheric disturbances taking place in the heavens and upon earth are due to the work of electric lighting companies,” a Southern minister announced.  Incredibly, the telephone was even more ominous than electricity. The social order would crumble. The constant ringing would drive men insane. There was also the peril of disease being spread over telephone lines. “Well, I suppose I must risk it,” a “wealthy well-educated and fashionable” Chicago matron decided, telephoning a household where there was scarlet fever, first having a servant makes sure “the sick children aren’t in the room where the telephone is.” Although, looking over past dire predictions about technology, I have to admit: sometimes they’re accurate. One of the big fears about the telephone was that it would make our intimate details become public knowledge.”We shall soon be nothing but transparent heaps of jelly to each other,” a British writer speculated in 1897.It wasn’t “soon” — it took 110 years. But yeah, that sounds about right.

Wind Power From Lake Michgan – We want it…No we don’t

Why would wind energy generation on or in Lake Michigan be controversial? Well first there is the “Chicago Attack”. This will just benefit large cities. Then there is the “pristine view” attack. It will block my beautiful view of this beautiful lake on a beautiful day. Finally there is the, “sure it will create jobs….but not ones I will be qualified for”.

Scandia Proposes 1,000-mw Lake Michigan Wind Farm

28 Comments Posted by John Davis – December 23rd, 2009

A Minnesota company is proposing to build a massive wind farm in Lake Michigan, but some of the residents of Michigan, which has some of the highest unemployment rates in the country, still aren’t pleased about the project that would bring green energy and jobs to the economically distressed region.

The Detroit Free Press says that Scandia Wind, a Minnesota firm partnering with a Norwegian wind developer, wants to put up a 1,000-megawatt wind farm just offshore from the communities of Pentwater and Ludington:

Several companies have been sniffing out offshore wind farm possibilities in Michigan, but Scandia was the first to jump in and publicly announce its plans. The turbines would be visible all along the shore, which takes in Silver Lake and Mears state beaches, Little Sable Lighthouse and Pentwater Harbor.

The firm wants to build foundations on the lake bottom, which is owned by the citizens of Michigan, and place 100 to 200 turbines — 5 to 10 megawatts each — on top.

The total size would make the wind farm bigger than any proposed new coal plant in Michigan and nearly as large as the Fermi 2 nuclear plant.

Local residents say the wind turbines would ruin the view off their beaches and hurt tourism. Scandia officials point out that the $3 billion project would put people to work to the tune of at least 2 million man-hours.

I attended the meeting in Ludington. Dirdal (Scandia Rep) said after the project was completed, only about 100-150 jobs would remain, and that national bidding for these positions wouldn’t guarantee they would be local. The skills for these jobs are not your garden variety skill sets.

I believe this project will only help those who need the energy and are willing to pay for it (Detroit and Chicago). Locally, aesthetically, and economically the Oceana and Mason residents will pay for it in lost property values and tax bases.

Julie Burdick

Wind turbines in Lake Michigan would lower property values and lower the tax base because the reason property values are high in this area is because of the access to the natural resources. This includes sailing, boating and fishing on the great lake and admiring the views from the beaches. This may work in Denmark etc. but it is not the reason people live and visit Pentwater and surrounding areas. Why should Pentwater bear the brunt of creating “green energy” for the surrounding metropolitan areas??

OH then there is the coal, oil and gas push back – they are unreliable and costly.

Dustin

I thought this was interesting…..”Despite their being cited as the shining example of what can be accomplished with wind power, the Danish government has cancelled plans for three offshore wind farms planned for 2008 and has scheduled the withdrawal of subsidies from existing sites. Development of onshore wind plants in Denmark has effectively stopped. Because Danish companies dominate the wind industry, however, the government is under pressure to continue their support. Spain began withdrawing subsidies in 2002. Germany reduced the tax breaks to wind power, and domestic construction drastically slowed in 2004. Switzerland also is cutting subsidies as too expensive for the lack of significant benefit. The Netherlands decommissioned 90 turbines in 2004. Many Japanese utilities severely limit the amount of wind-generated power they buy, because of the instability they cause. For the same reason, Ireland in December 2003 halted all new wind-power connections to the national grid. In early 2005, they were considering ending state support. In 2005, Spanish utilities began refusing new wind power connections. In 2006, the Spanish government ended — by emergency decree — its subsidies and price supports for big wind. In 2004, Australia reduced the level of renewable energy that utilities are required to buy, dramatically slowing wind-project applications. On August 31, 2004, Bloomberg News reported that “the unstable flow of wind power in their networks” has forced German utilities to buy more expensive energy, requiring them to raise prices for the consumer.”

Energy Efficient Roof Shingles

Home > Your Home > Environmentally Friendly > Articles > Energy Efficient Roof Shingles

image of energy efficient shinglesThe right roof is essential to designing an environmentally friendly and energy-efficient home. If you’ve got typical shingles or hot asphalt on your roof—as many homeowners do—you could be doing better. Below are a few cutting-edge roofing techniques that can cut your energy costs and make your house greener at the same time.

Use recycled shingles. If you want an environmentally friendly roof, the worst thing you can do is install 15-year, non-recycled shingles. These are among the most disposable building materials, are hardly ever recycled, and contain toxic volatile organic chemicals that evaporate under the heat of the sun. This means that just by sitting under the sun and heating up, your home is releasing toxic chemicals into the air. For a greener option, use recycled asphalt shingles that use reclaimed materials, reducing waste. These shingles often have a 50-year lifespan instead of 15, so you won’t have to replace them as often.

http://www.youtube.com/watch?v=kilR-4rQS5g

:}

Consider metal. Metal roofs are more energy-efficient than shingles. Metal roofing is typically made from aluminum, copper, or steel, and you should ensure that your roofing is lead-free. Metal does not have the kind of heat-absorption qualities shingles have, so it will absorb and radiate less heat into your home. In fact, the right color metal will actively reflect sunlight, keeping your home cooler in hot summer months when the sun is most intense. Metal roofing also stands up to the elements better than shingles typically do—it’s the best for rainwater catchment systems, and snow slides off it easily.

Reflective coatings. To make your shingled roof more energy-efficient, brush a reflective coating on. Uncoated shingled roofs typically absorb around 80% of the sunlight that hits them—heating your home in the summer and driving up your air conditioning bill. A coated roof, however, can reflect about 80% of heat—giving you significant energy savings.

Clay and slate. Two natural materials that make excellent green roofing choices, clay and slate are both energy-efficient, can be disposed of without pollution, and are much less toxic than shingles. Corrugated clay tiles encourage air flow on the surface of the roof, keeping the home cool in the summer. However, hail will shatter it, which is why it’s typically only used in warmer climates. Slate is far more durable—it can last up to 100 years with minimal maintenance. Slate can also be reclaimed and recycled.

Building-integrated photovoltaics (BIPV). This is a roofing system that’s coated with a film that converts sunlight into electricity—a solar-power coating for your roof. This system uses tiles or shingles, and the electric current flows on the edge of the roof. The tiles look like slate, and can be installed by most roofers—an electrician will also be needed to hook the solar-energy system up to your home’s electrical system. The charge it generates isn’t huge—about 1 kilowatt of energy per 100 square feet of tile

Roof turbines. Companies in the Netherlands, Scotland, and Britain are developing small turbines designed to install on roofs and convert wind power into home electricity. The turbines are typically around six feet across, and are usually mounted on the roof or a pole. Roof turbines feed energy into a converter, which transforms it into electricity for home use. They can typically provide enough power to operate lights, a refrigerator, a television, and a computer—providing significant energy savings. However, the amount of energy an individual house sees will depend on how windy its location is
