Renewable Energy says to turn profit in 2008


Reuters

Monday April 28, 2008

LONDON, April 28 (Reuters) - Britain's Renewable Energy Holdings plc (REH.L: Quote, Profile, Research) expects to turn a profit in 2008 after selling the rights to its wave energy technology in Australia, Chief Executive Mike Proffitt said on Monday to Reuters.

Renewable, which uses ocean waves to generate electricity and operates windfarms and landfills, reported 2007 losses of 1.5 million pounds ($2.98 million), "significantly" better than the 2.3 million pounds loss it expected, as revenues rose to 4.6 million pounds.

Shares of Renewable, which got 4.75 million pounds from the sale, rose 3.4 percent to 45.5 pence at 1041 GMT.

The company plans to increase its wind power generating capacity fourfold to 150 MW within two years, Proffitt added.

Wave-generated energy is expected to produce 60 MW within two years, he added, depending on the outcome of tests and the time taken to conduct environmental impact assessments, he added.

The UK government is aiming for a tenth of total electricity production to come from renewable sources by 2010, a government white paper shows, from roughly 5 percent now.

But that is poor compared with countries like Portugal where mainly wind-powered sources already provide 41 per cent of total electricity production. (Reporting by Hsu Chuang Khoo; Editing by David Cowell)

Bicycle-Sharing Program to Be First of Kind in U.S.


By BERNIE BECKER

The New York Times

Sunday 27 April 2008

WASHINGTON — Starting next month, people here will be able to rent a bicycle day and night with the swipe of a membership card.

A new public-private venture called SmartBike DC will make 120 bicycles available at 10 spots in central locations in the city. The automated program, which district officials say is the first of its kind in the nation, will operate in a similar fashion to car-sharing programs like Zipcar.

The district has teamed up with an advertiser, Clear Channel Outdoor, to put the bikes on the streets.

“There’s a lot of stress on our transit systems currently,” said Jim Sebastian, who manages bicycle and pedestrian programs for Washington’s Transportation Department. Offering another option, Mr. Sebastian said, “will help us reduce congestion and pollution,” as well as parking problems.

In the deal, Clear Channel will have exclusive advertising rights in the city’s bus shelters. The company has reached a similar deal with San Francisco. Chicago and Portland, Ore., are also considering proposals from advertisers.

For a $40 annual membership fee, SmartBike users can check out three-speed bicycles for three hours at a time. The program will not provide helmets but does encourage their use.

Similar programs have proved successful in Europe. The Vélib program in Paris and Bicing in Barcelona, Spain, both started around a year ago and already offer thousands of bicycles.

Mr. Sebastian, who started trying to bring bike-sharing to Washington even before its success in Paris and Barcelona, said he believed that the program could grow within a year and hoped that it would eventually offer 1,000 bicycles.

While automated bike-sharing programs are new to the United States, the idea of bike-sharing is hardly novel. Milan, Amsterdam and Portland have all had lower-tech free bike-sharing programs in the past, with Amsterdam’s dating to the 1960s.

But “studies showed that many bikes would get stolen in a day, or within a few weeks,” said Paul DeMaio, a Washington-area bike-sharing consultant. “In Amsterdam, they would often find them in the canals.”

Improved technology allows programs to better protect bicycles. In Washington, SmartBike subscribers who keep bicycles longer than the three-hour maximum will receive demerits and could eventually lose renting privileges. Bicycles gone for more than 48 hours will be deemed lost, with the last user charged a $200 replacement fee.

That technology comes with a price, which is one reason cities and advertisers started joining forces to offer bike-sharing. The European programs would cost cities about $4,500 per bike if sponsors did not step in, Mr. DeMaio said.

Cities realize “they literally have to spend no money on designing, marketing or maintaining” a bike-sharing program, said Martina Schmidt of Clear Channel Outdoor. Washington will keep the revenue generated by the program.

Bike-sharing has become a “public service subsidized by advertising,” said Bernard Parisot, the president and co-chief executive officer of JCDecaux North America, an outdoor advertiser that made a proposal to bring bike-sharing to Chicago.

But, Mr. Parisot added, if users had to pay all of the costs for bike-sharing, “they would probably just take a cab.”

The low cost could be one of the program’s major selling points.

At George Washington University in Foggy Bottom, one of the program’s 10 locations, students were unsure how often they would use SmartBike, but said its price made it worth a try.

“I’d probably use it more in the summer than winter,” said Dewey Archer, a senior. “But for $40? That’s cheaper than gas.”

Home Brew for the Car, Not the Beer Cup


By MICHAEL FITZGERALD

The New York Times

Saturday 27 April 2008

WHAT if you could make fuel for your car in your backyard for less than you pay at the pump? Would you?

The first question has driven Floyd S. Butterfield for more than two decades. Mr. Butterfield, 52, is something of a legend for people who make their own ethanol. In 1982, he won a California Department of Food and Agriculture contest for best design of an ethanol still, albeit one that he could not market profitably at the time.

Now he thinks that he can, thanks to his partnership with the Silicon Valley entrepreneur Thomas J. Quinn. The two have started the E-Fuel Corporation, which soon will announce its home ethanol system, the E-Fuel 100 MicroFueler. It will be about as large as a stackable washer-dryer, sell for $9,995 and ship before year-end.

The net cost to consumers could drop by half after government incentives for alternate fuels, like tax credits, are applied.

The MicroFueler will use sugar as its main fuel source, or feedstock, along with a specially packaged time-release yeast the company has developed. Depending on the cost of sugar, plus water and electricity, the company says it could cost as little as a dollar a gallon to make ethanol. In fact, Mr. Quinn sometimes collects left-over alcohol from bars and restaurants in Los Gatos, Calif., where he lives, and turns it into ethanol; the only cost is for the electricity used in processing.

In general, he says, burning a gallon of ethanol made by his system will produce one-eighth the carbon of the same amount of gasoline.

“It’s going to cause havoc in the market and cause great financial stress in the oil industry,” Mr. Quinn boasts.

He may well turn out to be right. But brewing ethanol in the backyard isn’t as easy as barbecuing hamburgers. Distilling large quantities of ethanol typically has required a lot of equipment, says Daniel M. Kammen, director of the Renewable and Appropriate Energy Laboratory at the University of California, Berkeley. In addition, he says that quality control and efficiency of home brew usually pale compared with those of commercial refineries. “There’s a lot of hurdles you have to overcome. It’s entirely possible that they’ve done it, but skepticism is a virtue,” Mr. Kammen says.

To be sure, Mr. Quinn, 53, has been involved with successful innovations before. For instance, he patented the motion sensor technology used in Nintendo’s wildly popular Wii gaming system.

More to the point, he was the product marketing manager for Alan F. Shugart’s pioneering hard disk drive when the personal computer was shifting from a hobbyists’ niche to a major industry. “I remember people laughing at us and saying what a stupid idea it was to do that disk drive,” Mr. Quinn says.

Mr. Butterfield thinks that the MicroFueler is as much a game changer as the personal computer. He says that working with Mr. Quinn’s microelectronics experts — E-Fuel now employs 15 people — has led to breakthroughs that have cut the energy requirements of making ethanol in half. One such advance is a membrane distiller, which, Mr. Quinn says, uses extremely fine filters to separate water from alcohol at lower heat and in fewer steps than in conventional ethanol refining. Using sugar as a feedstock means that there is virtually no smell, and its water byproduct will be drinkable.

E-Fuel has bold plans: It intends to operate internationally from the start, with production of the MicroFueler in China and Britain as well as the United States. And Mr. Butterfield is already at work on a version for commercial use, as well as systems that will use feedstocks other than sugar.

Ethanol has long had home brewers, and permits are available through the Alcohol and Tobacco Tax and Trade Bureau. (You must be a property owner and agree to make your ethanol outdoors.) But there are plenty of reasons to question whether personal fueling systems will become the fuel industry’s version of the personal computer.

For starters, sugar-based ethanol doesn’t look much cheaper than gas. It takes 10 to 14 pounds of sugar to make a gallon of ethanol, and raw sugar sells in the United States for about 20 cents a pound, says Michael E. Salassi, a professor in the department of agricultural economics at Louisiana State University. But Mr. Quinn says that as of January this year, under the North American Free Trade Agreement, he can buy inedible sugar from Mexico for as little as 2.5 cents a pound, which puts the math in his favor. While this type of sugar has not been sold to consumers, E-Fuel says it is developing a distribution network for it.

In addition, it’s illegal in the United States to operate a car on 100 percent ethanol, with exceptions for off-road vehicles like Indy cars and farm equipment. Mr. Quinn has a federal permit to make his own fuel, and believes that if MicroFuelers start popping up like swimming pools, regulators will adapt by certifying pure ethanol for cars.

Despite all the hurdles, Mr. Quinn and Mr. Butterfield may be on to something. There are plenty of consumers who want to reduce their carbon footprint and are willing to make an upfront investment to do it — consider the success of the Prius.

And if oil prices continue to rise, the economics of buying a MicroFueler will become only better and better.

The Real Cost of Tackling Climate Change
By Steven F. Hayward   

The Wall Street Journal (US)

Monday 28 April 2008
The usual chorus of environmentalists and editorial writers has chimed in to attack President Bush's recent speech on climate change. In his address of April 23, he put forth a goal of stopping the growth of U.S. greenhouse gas emissions by the year 2025.
"Way too little and way too late," runs the refrain, followed by the claim that nothing less than an 80% reduction in emissions by the year 2050 will suffice – what I call the "80 by 50" target. Both Hillary Clinton and Barack Obama have endorsed it. John McCain is not far behind, calling for a 65% reduction.

We all ought to reflect on what an 80% reduction of greenhouse gas emissions by the year 2050 really means. When we do, it becomes clear that the president's target has one overwhelming virtue: Assuming curbs are even necessary, his goal is at least realistic.


The same cannot be said for the carbon emissions targets espoused by the three presidential candidates and environmentalists. Indeed, these targets would send us back to emissions levels last witnessed when the cotton gin was in daily use.
Begin with the current inventory of carbon dioxide emissions – CO2 being the principal greenhouse gas generated almost entirely by energy use. According to the Department of Energy's most recent data on greenhouse gas emissions, in 2006 the U.S. emitted 5.8 billion metric tons of carbon dioxide, or just under 20 tons per capita. An 80% reduction in these emissions from 1990 levels means that the U.S. cannot emit more than about one billion metric tons of CO2 in 2050.

Were man-made carbon dioxide emissions in this country ever that low? The answer is probably yes – from historical energy data it is possible to estimate that the U.S. last emitted one billion metric tons around 1910. But in 1910, the U.S. had 92 million people, and per capita income, in current dollars, was about $6,000.

By the year 2050, the Census Bureau projects that our population will be around 420 million. This means per capita emissions will have to fall to about 2.5 tons in order to meet the goal of 80% reduction.

It is likely that U.S. per capita emissions were never that low – even back in colonial days when the only fuel we burned was wood. The only nations in the world today that emit at this low level are all poor developing nations, such as Belize, Mauritius, Jordan, Haiti and Somalia.

If that comparison seems unfair, consider that even the least-CO2 emitting industrialized nations do not come close to the 2050 target. France and Switzerland, compact nations that generate almost all of their electricity from nonfossil fuel sources (nuclear for France, hydro for Switzerland) emit about 6.5 metric tons of CO2 per capita.

The daunting task of reaching one billion metric tons of CO2 emissions by 2050 comes into even greater relief when we look at the American economy, sector-by-sector. The Energy Department breaks down emissions into residential, commercial (office buildings, etc.), industrial, and transportation (planes, trains and automobiles); electricity consumption is apportioned to each.

Consider the residential sector. At the present time, American households emit 1.2 billion tons of CO2 – 20% higher than the entire nation's emissions must be in 2050. If households are to emit no more than their present share of CO2, emissions will have to be reduced to 204 million tons by 2050. But in 2050, there will be another 40 million residential households in the U.S.

Today, the average residence in the U.S. uses about 10,500 kilowatt hours of electricity and emits 11.4 tons of CO2 per year (much more if you are Al Gore or John Edwards and live in a mansion). To stay within the magic number, average household emissions will have to fall to no more than 1.5 tons per year. In our current electricity infrastructure, this would mean using no more than about 2,500 KwH per year. This is not enough juice to run the average hot water heater.

You can forget refrigerators, microwaves, clothes dryers and flat screen TVs. Even a house tricked out with all the latest high-efficiency EnergyStar appliances and compact fluorescent lights won't come close. The same daunting energy math applies to the industrial, commercial and transportation sectors as well. The clear implication is that we shall have to replace virtually the entire fossil fuel electricity infrastructure over the next four decades with CO2-free sources – a multitrillion dollar proposition, if it can be done at all.
Natural gas – the preferred coal substitute of the moment – won't come close. If we replaced every single existing coal plant with a natural gas plant, CO2 emissions from electric power generation alone would still be more than twice the 2050 target. Most environmentalists remain opposed to nuclear power, of course. It is unlikely that renewables – wind, solar, and biomass – can ever make up more than about 20% of our electricity supply.
Suppose, however, that a breakthrough in carbon sequestration, a revival of nuclear power, and a significant improvement in the cost and effectiveness of renewables were to enable us to reduce the carbon footprint of electricity production. That would still leave transportation.

Right now our cars and trucks consume about 180 billion gallons of motor fuel. To meet the 2050 target, we shall have to limit consumption of gasoline to about 31 billion gallons, unless a genuine carbon-neutral liquid fuel can be produced. (Ethanol isn't it.) To show how unrealistic this is, if the entire nation drove nothing but Toyota Priuses in 2050, we'd still overshoot the transportation emissions target by 40%.

The enthusiasm for an 80% reduction target is often justified on grounds that national policy should set an ambitious goal. However, claims on behalf of alternative energy sources – biofuels, hydrogen, windpower and so forth – either do not match up to the scale of the energy required, or are not cost-competitive in current form.

How on God's green earth will we make up the difference? Someone should put this question to the candidates. And not let them slide past it with glittering generalities.
