The agreement and its program, which is known as IEA R&D Wind, is a collaborative venture among 19 contracting parties from 17 IEA member countries and the European Commission. he IEA, founded in 1974 within the framework of the Organization for Economic TCo-operation and Development (OECD) to collaborate on comprehensive international energy programs, carries out a comprehensive program about energy among 24 of the 29 OECD member countries. his report is published by the National Renewable Energy Laboratory (NREL) in TColorado, United States, on behalf of the IEA R&D Wind Executive Committee. It is edited by P. Weis-Taylor with contributions from experts in participating organizations from Australia, Canada, Denmark, Finland, Germany, Greece, Italy (two contracting par- ties), Japan, Mexico, the Netherlands, Norway, Spain, Sweden, the United Kingdom, and the United States.

This is driven by more effective The year 2000 was another good year for and cheaper machines and the use of wind energy. Worldwide electricity larger machines. The average turbine generation from wind now provides continues to grow in size and capacity, enough electricity to supply 75% of all reaching 800 kW in 2000, compared to Denmark’s needs. 440 kW five years ago. Machines of 3 MW and above are now being developed by Much of the current market for wind several companies, the first of which is energy is driven by the very low life-time expected to be erected in 2001 in Sweden. emissions that the technology offers. But wind energy also provides an opportunity The interest and level of commercial for industry, enables rapid capacity activity associated with offshore wind building, removes fuel supply cost energy increased again during 2000. Projects uncertainties and increases the diversity were developed in the UK (4 MW), in and security of electricity supply. Denmark (40 MW) and in Sweden (10 MW). The new market for large offshore machines The value of wind energy is increasingly has created much fresh thinking on both recognized by governments, which has the foundations and installation methods. enabled sustained high growth at 30% per Offshore reliability has also been identified annum or above since reporting began in as an area needing continued research in 1994. Wind continued to show growth at order to achieve acceptable availabilities. 30% both globally and in the reporting IEA countries this year. At the end of 2000, the I hope you will find this IEA Wind Energy global wind capacity reached 17.6 GW. The Annual Report both interesting and total installed capacity in the IEA member informative. This year we have expanded countries reached 15.4 GW, with the IEA the Overview chapter based on the countries now accounting for 88% of national reviews of the IEA R&D Wind global installed capacity.
