Wind energy is an economic form of energy generation reducing both running costs and environmental harm  The installation costs of an entire wind farm are, admittedly, fairly high – although they pale into insignificance compared to an oil station or a nuclear plant – but after that there is almost no associated cost whatsoever. In addition to which farms can be built incrementally; a half completed wind farm is simply one that is half its original size for virtually any other form of power generation it’s an all or nothing proposition [i] .  Furthermore, many experts agree that so-called micro-renewables will play an increasingly important role in the energy future of the planet and wind energy is the example par excellence of how this can be done; the most basic homemade windmill can power a generator and wind power predates electricity – offshore and on – by centuries.
