The government's environment, energy, finance and tax ministries are currently investigating ways of removing the burden of energy and environment taxes from consumers to fuel. Such a change would improve the economics of wind energy in Denmark, which should also be positively influenced by a 5% increase in coal prices this year. Danish utilities are among the biggest customers for coal in the world. Payments for wind power are set at 85% of the consumer price of electricity. For this reason, too, the Danish wind sector is keenly watching the rising prices for trade on the Scandinavian electricity exchange in Oslo. Norway's hydro reserves are 30% below normal after a particularly dry winter and spring.
