Ann Arbor to install LED street lights downtown

blog.mlive.com

<<...Mayor John Hieftje on Tuesday proclaimed Ann Arbor to be the first city in the country to pledge to fit all its downtown street lights with the more efficient LED light bulbs.

Then with the CTN cameras rolling at a afternoon press conference, Hieftje turned to Mike Bergren, the city's assistant field operations manager, and asked, "First in the world, maybe?"

Bergren shrugged. "Possible."

As part of its goal to be a national leader in energy efficiency, the city announced that it will replace all 1,046 of its 120-watt incandescent street lights downtown with the 56-watt light-emitting diode. Hieftje estimated that would take two years.

It will cost $630,000 to do the installations, which is being paid for by the Downtown Development Authority. Eventually, Hieftje said the entire city will have LED lights.

Once completed, project officials estimate converting all its downtown lights will save the city $100,000 a year in energy costs and reduce greenhouse gas emissions by the equivalent of taking 400 cars off the road for a year. The LED lights also provide better light quality for improved visibility and safety, according to LED City, an organization of government and industry parties that is promoting their use.

Raleigh, N.C., and Toronto are two other cities that have installed LED lights in their downtown, according to Greg Merritt, a spokesman for CREE, the company that manufacturers semiconductors in LEDs. They just haven't committed to doing the entire downtown like Ann Arbor has, Merritt said.

Ann Arbor recently completed converting all of its traffic signal lights to LEDs.

Like those traffic lights, a big savings with the street lights will be with maintenance, Bergren said.

The older street lights have a two-year life after which they all had to be replaced. The LEDs have a seven-year warranty and are expected to last as long as 10 years.

The LEDs also don't contain mercury, something that is in the city's common street lights, Bergren said...>>

Morgan Stanley sees $1 trillion green mkt by 2030

Global sales from clean energy sources like wind, solar and geothermal power and biofuels could grow to as much as $1 trillion a year by 2030, U.S. bank Morgan Stanley (MS.N: Quote, Profile, Research) has estimated.

Global population growth and soaring prices for fossil fuels are driving the market, along with dropping costs in clean energy and concern about energy security and climate change, the bank said in a research note issued on Wednesday.

On the market's upside, revenues could reach $505 billion in 2020, or nearly nine times the level in 2005, and hit $1.02 trillion 10 years later, the bank said.

As a comparison, the gross domestic product of the the United States, the world's largest economy, hit $13.2 trillion last year.

"The global risks posed by climate change are driving spending and investment in clean energy solutions, which (unlike the oil shock that spawned the first wave of energy solutions in the 1970s) is durable and accelerating," Morgan Stanley said in the note.

The bank also initiated coverage of the clean energy industry. It rated the following companies as overweight-volatile: thin film solar company First Solar Inc (FSLR.O: Quote, Profile, Research), solar company SunPower Corp (SPWR.O: Quote, Profile, Research), biofuel company VeraSun Energy Corp. (VSE.N: Quote, Profile, Research), and emissions reducers Fuel Tech Inc (FTEK.O: Quote, Profile, Research).

The report cautioned that sales could be reduced in the unlikely event that world governments change direction on climate change policy and stop taking steps to monetize greenhouse gas emissions. Peace in the Middle East could also push down oil prices, which could slow growth.

Shares in renewable energy companies also could be volatile in the short term, it said.

The bank was particularly bullish on solar power. Market penetration of solar in electricity generation could rise from levels almost too small to measure in 2005 to 11.2 percent in 2030, while wind power could go from 0.9 percent to 9.6 percent by 2030, it said.

Solar would take more market share as costs decline for things like panels that convert the sun's rays into power. The cost of solar power should sink from $8 per Gigawatt installed in 2005 to $1.60 per GW by 2030. Wind power, which was $2 per GW. would cost about the same through 2030, it said.

Penetration of biofuels like ethanol and biodiesel in transportation could grow from around 1 percent in 2005 to 21 percent in 2030, it said, assuming cars boost fuel efficiency.

Morgan Stanley was not the only bank this week to highlight green energy. Government efforts to tackle climate change are creating a "megatrend" investment opportunity that should tempt even those skeptical about the nature and pace of global warming, Deutsche Bank analysts said on Thursday in China.

Deutsche Bank has attracted about $8.55 billion into climate change funds, which target companies that cut greenhouse gases or help people adapt to a warmer world, in sectors from agriculture to power and construction.

Global investment in renewable energies jumped to a record $100 billion in 2006 and will likely rise to about $120 billion in 2007, the U.N. Environment Program said this summer.

A Young Tinkerer
Builds a Windmill,
Electrifying a Nation
Mr. Kamkwamba's Creation
Spurs Hope in Malawi;
Entrepreneurs Pay Heed
By SARAH CHILDRESS
December 12, 2007; Page A1

MASITALA, Malawi -- On a continent woefully short of electricity, 20-year-old William Kamkwamba has a dream: to power up his country one windmill at a time.

So far, he has built three windmills in his yard here, using blue-gum trees and bicycle parts. His tallest, at 39 feet, towers over this windswept village, clattering away as it powers his family's few electrical appliances: 10 six-watt light bulbs, a TV set and a radio. The machine draws in visitors from miles around.


WSJ's Sarah Childress meets William Kamkwamba, a 20-year-old Malawian who built a makeshift windmill to power his family's home.
Self-taught, Mr. Kamkwamba took up windmill building after seeing a picture of one in an old textbook. He's currently working on a design for a windmill powerful enough to pump water from wells and provide lighting for Masitala, a cluster of buildings where about 60 families live.

Then, he wants to build more windmills for other villages across the country. Betting he can do it, a group of investors are putting him through school.

"I was thinking about electricity," says Mr. Kamkwamba, explaining how he got hooked on wind. "I was thinking about what I'd like to have at home, and I was thinking, 'What can I do?' "

To meet his family's growing power needs, he recently hammered in a shiny store-bought windmill next to the big one at his home and installed solar panels. He has another windmill still in its box that he'll put up at a house 70 miles away in the capital, Lilongwe, where he now goes to school.

A few years ago, he built a windmill for the primary school in Masitala. He used it to teach an informal windmill-building course. Lately, he has offered to help the village handyman down the road build his own machine.

"Energy poverty" -- the scarcity of modern fuels and electrical supplies in poor parts of the world -- is a subject of great interest to development economists. The windmill at the Kamkwamba family compound, a few brick buildings perched on a hill overlooking the village, has turned it into a stop for the curious: People trekking across Malawi's arid plains drop by. Villagers now regularly make the dusty walk up the hill to charge their cellphones.

The contraption causing all the fuss is a tower made from lashed-together blue-gum tree trunks. From a distance, it resembles an old oil derrick. For blades, Mr. Kamkwamba used flattened plastic pipes. He built a turbine from spare bicycle parts. When the wind kicks up, the blades spin so fast they rock the tower violently back and forth.

Mr. Kamkwamba's wind obsession started six years ago. He wasn't going to school anymore because his family couldn't afford the $80-a-year tuition.


When he wasn't helping his family farm groundnuts and soybeans, he was reading. He stumbled onto a photograph of a windmill in a text donated to the local library and started to build one himself. The project seemed a waste of time to his parents and the rest of Masitala.

"At first, we were laughing at him," says Agnes Kamkwamba, his mother. "We thought he was doing something useless."

The laughter ended when he hooked up his windmill to a thin copper wire, a car battery and a light bulb for each room of the family's main house.

The family soon started enjoying the trappings of modern life: a radio and, more recently, a TV. They no longer have to buy paraffin for lantern light. Two of Mr. Kamkwamba's six sisters stay up late studying for school.

"Our lives are much happier now," Mrs. Kamkwamba says.

The new power also attracted a swarm of admirers. Last November, Hartford Mchazime, a Malawian educator, heard about the windmill and drove out to the Kamkwamba house with some reporters. After the news hit the blogosphere, a group of entrepreneurs scouting for ideas in Africa located Mr. Kamkwamba. Called TED, the group, which invites the likes of Al Gore and Bono to share ideas at conferences, invited him to a brainstorming session earlier this year.

In June, Mr. Kamkwamba was onstage at a TED conference in Tanzania. (TED stands for Technology Entertainment Design). "I got information about a windmill, and I try and I made it," he said in halting English to a big ovation. After the conference, a group of entrepreneurs, African bloggers and venture capitalists -- some teary-eyed at the speech -- pledged to finance his education.

His backers have also showered him with new gadgets, including a cellphone with a hip-hop ringtone, a laptop and an iPod. (Kelly Clarkson's "Breakaway" is his current favorite tune.) They rewired his family's house, replacing the homemade switches he made out of flip-flop parts.

They're paying for him to attend an expensive international academy in the capital, Lilongwe, for children of expatriate missionaries and aid workers. But his teacher, Lorilee MacLean, sometimes worries about his one-track mind and about all the attention he's getting.

"I don't want him to be seen as William the windmill maker," said Mrs. MacLean one day recently. While Mr. Kamkwamba quietly plowed through homework, his classmates were busy gossiping and checking their Facebook profiles.

Mr. Kamkwamba has taught his family to maintain the windmill when he's away at school. His sister Dolice and cousin Geoffrey can quickly scamper up the tower, as it sways and clatters in the wind, to make repairs.

A steady stream of curiosity seekers make the trip to the Kamkwamba compound -- mostly unannounced. The visits are unsettling for the reserved family.

One afternoon, a pair of Malawian health workers came by to get a closer look and meet Mr. Kamkwamba. The family scattered, leaving the pair -- dressed in shirts and ties for the occasion -- standing awkwardly in the yard.

"We have heard about this windmill, and so we wanted to see it for ourselves," one finally spoke up. Mr. Kamkwamba came around to shake hands, then quickly moved away to show another visitor around.

Jealousy is a social taboo in these parts, but Fred Mwale, an educator who works in Wimbe, the area that includes Masitala, says the family's new prosperity is causing some tensions.

"People do desire what is happening here. They come, and admire," he says. "They think that they might get the same support if they build a windmill."

Down the hill, the village handyman started building his own windmill after secretly studying Mr. Kamkwamba's. A gust of wind blew the blades off the man's first few attempts. Mr. Kamkwamba offered to help him rebuild, but got no reply.

"I'm waiting to see if he's serious," Mr. Kamkwamba says.
