Windmills and Windwheels,ould only survive in economic niches of little importance. Today, while energy production based on the burning of coal and oil or on the splitting of the uranium atom is meeting with increasing resistance, regardless of the various reasons, the re-emergence of wind power is an almost inevitable consequence.

Rotor Aerodynamics,cy of the energy conversion in the wind turbine. As in any other regenerative power generation system, it is this efficiency of the energy collector which is of prime importance with regard to the overall economics of the system.

Wind Turbine Installation and Operation,easons. The planning of wind energy projects falls right into this area of tension and is thus less of a technical problem than one of striving, as a rule over long periods, to achieve a balance between the various interests until an equitable consensus is found.

Mechanical Drive Train and Nacelle,nverting mechanical energy into electrical energy represent ”conventional” power plant technology, as it were. But a conclusion that this area would be ”state-of-the-art” and that it should, therefore, not pose any particular problems is not completely true.

Environmental Impact,ng generations with regard to the disposal of radioactive waste. The utilisation of wind energy thus unreservedly deserves the attribute ”environmentally friendly”. All the same, even the operation of wind turbines is not without its effects on the environment.

Commercial Applications of Wind Turbines,the turbines takes up a significant place in these considerations since the fields of application available for small wind turbines with a power of a few kilowatts differ fundamentally from those for large turbines in the megawatt power range.

Windmills and Windwheels,ible now to tell from the remainders of historical ”wind power plants” just how important a role wind power played in the past. The triumphal spread of the cheap coal and oil fuels and of easy energy distribution in the form of electricity was so complete that the losers, windmills and windwheels, c
