The uneconomic nature of wind farms has been well documented. They require 100% backup from conventional electricity generators such as coal or gas fired power stations. They exist due to Government subsidies that have come about due to the mistaken believe that they lower greenhouse gas emissions (which they don't) and greenhouse gas emissions are not a worry anyway, since CO2 is NOT a pollutant.
SOUTH AUSTRALIA must stop allowing wind farms to be built. Subsidies for doing so must be removed. Existing wind farms must be phased out and our countryside restored to its former glory. Such work can be classified as "Green jobs" and earmarked for those unemployed Green supporters. This Green icon is not wanted in South Australia. Let's make South Australia a WINDMILL FREE State and become more prosperous by doing so. Some useful links are:
