In 2000 more than 18% of Dutch sustainable energy was wind generated and at 442 MW, installed wind capacity was eight times that of the 55 MW in1990, according to a new report from Statistics Netherlands and the environment and energy agency NOVEM. Wind power production increased fifteen-fold during the last decade. But although production of sustainable energy was 12% higher in 2000 than in 1999, its share of the total Dutch energy supply remained modest at just 1.2 %. Although enough to provide nearly 9% of Dutch households with heat and light, it is clear the Netherlands has a long way to go if it is to meet its target for 5% renewables in the energy mix by 2005 and 10% by 2020. The targets are based on building 1500 MW of onshore wind by 2010, more than treble the existing capacity. A breakdown of the market into renewables technologies shows wind growing strongly but bio-energy still dominant. Energy from the combustion of organic waste or biomass and the fermentation of biomass accounted for 74% of total renewables production in 2000 -- down from 92% in 1990. Biomass combustion has been boosted by recent new projects and more wood is being used as fuel by industry. More electricity plants are also burning biomass, says NOVEM. Solar, despite good growth (solar boiler systems climbed from 2000 in 1990 to 50,000 in 2000) has a total share of just 1.3% of the sustainable energy market. Hydro, boosted by unusually high rainfall, had an exceptionally good year in 2000 and rose by 59% on 1999. In the longer term, however the recent decision to revoke hydro's ecotax exemption is likely to stem further expansion. In total the use of sustainable energy sources contributed to a reduction in fossil fuel use equivalent of 2.4 megatons of C02 in 2000.
