It doesn’t look like the heart of a green revolution. The huge chimneys stick up above the line of pine trees and don’t make for the most scenic view as you wander around the clear blue waters of the nearby lake.
But it is this power plant that has helped the small Swedish city of Vaxjo become arguably the greenest place in Europe. On closer observation, the only thing emerging from the chimneys is the faintest mists of steam. And inside it smells more like a sauna(桑拿) than a furnace(炉子). That’s because it is not oil fuelling the plant, but woodchip and other wood waste from the area’s sawmills. And as well as generating electricity, it also supplies 90 per cent of this southern Swedish town with heating and hot water.
The gases produced as the wood burns are changed into liquid form, and are purified before they reach the chimney. And instead of wasting this liquid, the power plant pumps it around town. Some runs out of the town’s public taps; the rest is directed through pipes that run through individual heaters, warming homes and offices.
The pile of wood chippings in the yard towers above head height and takes almost five minutes to walk around. That’s enough to keep Vaxjo warm on the snowiest day in winter, or supply it with hot water for a fortnight in summer, and it’s good way of using the paper industry’s waste. As well as the centuries-- old Swedish policy of planting a new tree for every one felled, the ashes swept out of the furnace each day find their way back to the forest as fertilizer(肥料).
It was this green plant that netted Vaxjo the European Union’s award for sustainable(可持续的)development, making it the greenest city on the continent.
However, it is not just the citizen’s consciences and moral histories to which the town’s current day authorities are appealing. They know how to talk to their wallets too. Oil-generated electricity costs about 16,000 kronor a year(￡1,170) per person, while the new power plant’s electricity comes in at two thirds of the price.
They’ve been planning for over ten years to become a “Fossil Fuel Free City”. But according to Anders Franzen, the head of planning and development department at the city council: “The battle in the energy sector has been won, yes, but the next battleground is transport.”
