    Get your facts in order before you make a video. Wind turbines cause 0.01% of bird deaths every year while buildings cause 58% of bird deaths so does that mean we shouldnt build buildings

      Yes, but we need buildings to live in, we do not need these part time power systems.

    The heading to this video says that wind is cost effective. It is not, it is very expensive despite what the media publishes. It is patently obvious when the cost per unit is high where there is a large percentage of renewable energy. The costs include subsidies, installation of extra infrastructure, the cost of running back up power to ensure security of supply and to balance the grid load.

    Some disadvantages are high initial cost,bird death and not constant and not available at all places.
