First nation people would support windmill technology because they recognize that windmill provide a clean source of renewable energy.
They are now aware of the dangerous effects of using non renewable energy namely fossil fuels which have been implicated in environment pollution and rise in greenhouse gases.
Windmills use wind power which is clean source of energy that can be relied on for decades and is cost effective, pollution free, clean and sustainable. One household can have all its energy needs met by one wind mill turbine. Windmills create power without using fossil fuels.
