Ashton Hayes is aiming to become the first village in England to become carbon neutral



English village spearheads carbon neutral drive

ASHTON HAYES, England (AFP) - A small English village last year set itself the aim of becoming the country's first carbon neutral community -- only to be swamped with requests for advice from around the world.

"I simply didn't want to tell my grandchildren that we knew the effects of the climate change and that we didn't care," said Garry Charnock, the man behind Ashton Hayes' "Going carbon neutral" campaign.

"Today, about 40 villages and cities such as Manchester, Abu Dhabi and Rotterdam
have contacted us for advice on what to do," he added, also citing interest from Australia, New Zealand and the United States.

The village is set amid the rolling hills of Cheshire, northwestern England, a short drive from the well-to-do city of Chester and not far from the Welsh border.

Charnock first had the idea of spearheading a carbon-cutting drive after going to a debate on climate change at a literary festival in Wales. His first act was to ditch his high-powered BMW for a less gas-guzzling, compact car.

Today, the most visible signs of his campaign can be seen in the village primary school and the pub, which he and others who have joined the bandwagon describe as the "lungs" of the community.

"They influence our community, the school is an excellent catalyst. And the children involve their parents," said Tracey Todhunter, another member of the 40-strong project team.

The campaigners have fitted a small wind turbine and solar panel on the roof of the school to heat its water, while an "eco-team" of a dozen pupils ensure as much as possible is recycled, and turn off any unused electrical device.

The school choir has written a rap song, dubbed "Carbon neutral," which they hope to sing on July 7 in London, when "Live Earth" concerts are scheduled to be held around the world.

Barry Cooney, manager of the Golden Lion pub, agreed to join the campaign in December, even though he admits to being "a bit incredulous" at first.

Four months later, he is over the moon.

His monthly electricity bill has gone down from 1,000 pounds (1,473 euros, 1,930 dollars) to 650 pounds after he changed his light bulbs, turned down the heating and switched off devices not being used.

"Ideas pop out all the time. Each initiative is a step forward but we can't do everything in the same time. You can't change your way of life in one day," said Charnock.

For the moment, the focus is on energy conservation. As well as cutting use, the village also wants to produce its own electricity using a micro-grid fueled with wood provided for free by the conservation charity The Woodland Trust.

Villagers have also proposed to utility Scottish Power that it install wind turbines in a field offered by a local landowner.

"In return, we would have a wind turbine and we could sell the excess output of electricity," says Charnock.

In other initiatives, a system by which villagers can offset their carbon emissions is being set up, with hundreds of trees being planted, and solar panels cropping up on some houses.

A teleconference room, to cut the need for people travelling, is also under construction.

Many households have begun using compost and recycling to cut down on waste production. Over one year recycling has improved by eight percent.

"That's the highest in the county," said Alison Ambrose, proudly.

The village has been given a subsidy of 26,000 pounds from the Department for Environment Food and Rural Affairs to share its experiences. A conference scheduled for mid-April in Chester is already sold out.

Monday view: Cheap solar power poised to undercut oil and gas by half

Within five years, solar power will be cheap enough to compete with carbon-generated electricity, even in Britain, Scandinavia or upper Siberia. In a decade, the cost may have fallen so dramatically that solar cells could undercut oil, gas, coal and nuclear power by up to half. Technology is leaping ahead of a stale political debate about fossil fuels.

Anil Sethi, the chief executive of the Swiss start-up company Flisom, says he looks forward to the day - not so far off - when entire cities in America and Europe generate their heating, lighting and air-conditioning needs from solar films on buildings with enough left over to feed a surplus back into the grid.

The secret? Mr Sethi lovingly cradles a piece of dark polymer foil, as thin a sheet of paper. It is 200 times lighter than the normal glass-based solar materials, which require expensive substrates and roof support. Indeed, it is so light it can be stuck to the sides of buildings.

Rather than being manufactured laboriously piece by piece, it can be mass-produced in cheap rolls like packaging - in any colour.

The "tipping point" will arrive when the capital cost of solar power falls below $1 (51p) per watt, roughly the cost of carbon power. We are not there yet. The best options today vary from $3 to $4 per watt - down from $100 in the late 1970s.

Mr Sethi believes his product will cut the cost to 80 cents per watt within five years, and 50 cents in a decade.

It is based on a CIGS (CuInGaSe2) semiconductor compound that absorbs light by freeing electrons. This is then embedded on the polymer base. It will be ready commercially in late 2009.

"It'll even work on a cold, grey, cloudy day in England, which still produces 25pc to 30pc of the optimal light level. That is enough, if you cover half the roof," he said.

"We don't need subsidies, we just need governments to get out of the way and do no harm. They've spent $170bn subsidising nuclear power over the last thirty years," he said.

His ultra-light technology, based on a copper indium compound, can power mobile phones and laptop computers with a sliver of foil.

"You won't have to get down on your knees ever again to hunt for plug socket," he said

Michael Rogol, a solar expert at Credit Lyonnais, expects the solar industry to grow from $7bn in 2004 to nearer $40bn by 2010, with operating earnings of $3bn.

The sector is poised to outstrip wind power. It is a remarkable boom for a technology long dismissed by experts as hopelessly unviable.

Mr Rogol said he was struck by the way solar use had increased dramatically in Japan and above all Germany, where Berlin's green energy law passed in 2004 forces the grid to buy surplus electricity from households at a fat premium. (In Britain, utilities may refuse to buy the surplus. They typically pay half the customer price of electricity.)

The change in Germany's law catapulted the share price of the German flagship company SolarWorld from €1.38 (67p) in February 2004 to over €60 by early 2006.

The tipping point in Germany and Japan came once households twigged that they could undercut their unloved utilities. Credit Lyonnais believes the rest of the world will soon join the stampede.

Mike Splinter, chief executive of the US semiconductor group Applied Materials, told me his company is two years away from a solar product that reaches the magic level of $1 a watt.

Cell conversion efficiency and economies of scale are galloping ahead so fast that the cost will be down to 70 US cents by 2010, with a target of 30 or 40 cents in a decade.

"We think solar power can provide 20pc of all the incremental energy needed worldwide by 2040," he said.

"This is a very powerful technology and we're seeing dramatic improvements all the time. It can be used across the entire range from small houses to big buildings and power plants," he said.

"The beauty of this is that you can use it in rural areas of India without having to lay down power lines or truck in fuel."

Villages across Asia and Africa that have never seen electricity may soon leapfrog directly into the solar age, replicating the jump to mobile phones seen in countries that never had a network of fixed lines. As a by-product, India's rural poor will stop blanketing the subcontinent with soot from tens of millions of open stoves.

Applied Materials is betting on both of the two rival solar technologies: thin film panels best used where there is plenty of room and the traditional crystalline (c-Si) wafer-based cells, which are not as cheap but produce a higher yield - better for tight spaces.

Needless to say, electricity utilities are watching the solar revolution with horror. Companies in Japan and Germany have already seen an erosion of profits because of an effect known "peak shaving". In essence, the peak wattage of solar cells overlaps with hours of peak demand and peak prices for electricity in the middle of the day, crunching margins.

As for the oil companies, they are still treating solar power as a fringe curiosity. "There is no silver bullet," said Jeroen Van der Veer, Shell's chief executive.

"We have invested a bit in all forms of renewable energy ourselves and maybe we'll find a winner one day. But the reality is that in twenty years time we'll still be using more oil than now," he said.

Might he be wrong?
