Spain’s biggest power company, Endesa, is building two plants to generate electricity from olive residues, the leftovers from olive oil production. The plants, due to be completed in late 2001, will produce enough electricity to meet the household needs of 100,000 people, and Endesa may build dozens more. Other planned biomass projects in Spain include plants that will make energy from cattle dung, chicken doo-doo, straw, and almond shells. Sweden, which already generates 19 percent of its power through biomass, is also likely to step up biomass production to help replace the power that will be lost when the country phases out its nuclear plants.
