Denmark's CO2 emissions have fallen 8.2% since 1988, not far off the half way mark for reaching the national goal of a 20% cut by 2005. Significantly the reduction is being achieved at the same time as energy use is rising and the economy is expanding. In the same period, the gross national product increased by 25%, while last year 2.5% more energy was consumed than the previous year. This means that the energy consumed was used 18% more effectively, reports the Danish energy ministry. The share of energy from natural gas grew 9.5% and from renewables 8%, while oil consumption fell 9% and coal 1%. Denmark was self reliant in energy last year. Renewable energy, mainly from wind power, met 10% of Denmark's energy needs in 1998, compared with 9% in 1997 and 6% in 1988. The official goal contained in Energy 21, the government's policy paper, is for 12-14% of demand to be met by renewables in 2005.
