But the ocean itself is proving to be an efficient and environmentally friendly source of energy. Blustery winds threaten to topple Iain Russell off the dock into the narrow stretch of water connecting the Irish Sea and the Atlantic Ocean. But those gusts are a key reason why his company, Wave Dragon Ltd., plans to anchor the world's largest wave energy converter several miles out to sea off this small town on the southwestern Welsh coast. More than a century after the industrial revolution's coal mines and steel works turned Wales' lush green valleys into stark black hills, the strong winds that batter its coastline are playing a major part in the local government's plan to turn the country green again. By 2025, Wales wants to generate all its electricity from renewable sources and even become a net exporter of power. Wales is betting that two huge projects _ a $30 billion tidal barrage in the Severn Estuary and the largest biomass plant in the world in Port Talbot _ will produce most of the electricity needed to reach its 2025 target. For the rest, the local government is hoping that its natural winds, streamlined bureaucracy, access to skilled labor, proximity to universities and state funding will prove enticing to companies in both the renewables and clean technology sectors. Going green could make or break Wales following the death of the mining industry in the 1980s. While Cardiff has blossomed from a provincial city into a significant capital in recent years under a retail- and services-led boom, rural Wales has limped along on tourism and agriculture. A parade of companies deciding to make products from cars to cell phone chargers in Wales shows that the strategy is paying off. Wave Dragon was encouraged to move its headquarters from Denmark to Wales in part by a $10 million grant from the Welsh European Funding Office. "The funding dried up in Denmark so we started looking elsewhere," said Russell. "We also discovered how much more wave energy there is here than in the North Sea." The company plans to locate its wave energy converter about 2 miles to 3 miles off the Welsh coast for testing over three to five years. The barge produces electricity directly from the power of the water by first enhancing, then pulling in oncoming waves to turbines in the bottom of the structure. Russell said that the project could produce enough electricity each year during the testing phase to meet the demands of between 2,500 and 2,000 homes. The company hopes to eventually sink around 10 of the structures some 10 miles to 12 miles out to sea to form Britain's first commercial wave energy farm _ but the plan is dependent on nearly $71 million of extra funding Wave Dragon is seeking from private sources. Wales' government is "very committed to the renewables goal, but we need the cutting-edge technologies that the private sector can offer," said David Jones, vice president of International Business Wales, the trade and investment arm of the Welsh Assembly. Mining, once a mainstay of the economy, is no longer a major source of revenue or employment in Wales. The economy is now underpinned largely by the services and production industries. Agriculture, forestry and fishing also contribute to a lesser degree. In 1979, Wales' gross domestic product was 93 percent of the British average. That has since fallen to just 77 percent. Over the same period, Ireland _ the so-called Celtic tiger _ has seen its GDP go from 60 percent of the UK average to 104 percent thanks to low corporate tax, investment in higher education and EU membership. Wales hopes to emulate that success with its state funding for renewables and clean technology. On the outskirts of Cardiff, where G24 Innovations makes silicon-free thin film solar cells to charge mobile phones, the company is planning to install a massive wind turbine in its parking lot later this year. That will enable the factory to run on renewable energy and eventually sell electricity back to the grid _ making it one of the first factories in the world to use renewable energy to make a renewable product. G24 is initially targeting the African and Indian markets, where mobile phone penetration is growing but electricity grids are in short supply. The company already has a contract with Vodacom in Tanzania, Lesotho and Kenya. When a new production line is ready later this year, G24 plans to raise production to several million units per year. The company, which is seeking around $40 million to $50 million in further funding and eventually hopes to list on a stock exchange, also aims to branch out into backpacks with built-in chargers for both emerging and European markets. A few miles to the west, Connaught Engineering Ltd. has invested $24 million in a factory to produce a CO2 emissions-cutting engine component that can be retrofitted to commercial vans. The system saves both fuel and an estimated 25 percent of carbon emissions on diesel home delivery vans. Tesco PLC, Britain's largest grocery chain, is one of several companies testing the hybrid retrofit system. If successful, Connaught expects orders of around 4,000 units a year. Connaught CEO Tony Martindale said the company was initially hesitant when approached by the Welsh Assembly, looking instead at sites in Germany, before being won over by a $6.7 million grant. "The universities here will also be a feed for research and development in our future business," he said, including the development of the world's first gasoline/electric engine high-performance sports coupe. Similarly, G24 considered London and Germany before deciding to invest $75 million of its own funds to build its factory in Wales. "Quite frankly, the difference in the rhetoric between the political circles in talking about renewables and actually how difficult it was to go into business was quite stunning," said chairman Robert Hertzberg, a former California lawmaker, of his experiences in the United States. "Here's a place that was the backbone of the industrial revolution in the coal mines and now all of a sudden, they can be the backbone of the next generation in terms of green energy."
