The country is already covering many of its energy needs with renewable resources such as bioethanol to fuel its cars and wood to fire its power plants.
Are forests the fuel of the future?If Swedish entrepreneur Per Carstedt is right, the next big energy revolution will really be a step backward. "The industrial age began with the transition from wood to fossil fuels," he says. "Now we're going in the other direction."
Carstedt reaches into a bucket of wood chips. This is the raw material he wants to convert into modern society's lifeblood -- fuel. But before wood can power a car engine, it needs to be chemically processed. And that is exactly what's happening on the top floors of the Örnsköldsvik plant in northern Sweden. Carstedt steps into a large room crowded with steel pipes and aluminium tanks. On the end of each pipe is a safety seal.
"Government regulations," the fifty-year-old Carstedt says with a smile. The material flowing through the pipes is quite popular on dark Scandinavian nights: alcohol -- or rather ethanol to be specific. "Nobody is allowed to tap it here without permission," he says.
