Since it opened a year ago the telephone information line of the National Bureau for Wind Energy has had more than 1000 calls. Apart from the expected quota of primary and secondary school pupils, most calls were from people who had invested or were willing to invest in wind turbines. For this category of caller the bureau has published a step-by-step procedure for installing one or more turbines. Callers are mainly farmers, says Marielle van Aggelen from the bureau, who regard wind turbines as a means to extra income. Interest among the farming community is such that the national agricultural organisation, LTO, has started talks with Pawex, the Netherlands' association of wind turbine owners. As well as calls from potential and current wind plant operators, a number of questions on the hot line were put by local government employees. According to Van Aggelen a world can be gained for wind energy by overcoming existing prejudices on noise and the height of wind turbines.
