The way wind power has ramped up in the UK is amazing over the last few years.
This is why people that claim we are doing nothing to try to alleviate climate change are talking nonsense.
You only have to fly over the North Sea to see the sheer scale of offshore wind which many people do not appreciate.
But ...
Wind power in itself does have issues. The irregular supply. The problems in getting the power from where it is needed to the consumer - lack of electrical infrastructure. The issues regarding sourcing of the materials (rare earths for turbines). The strategic weakness of having a singificant proportion of power generation in the North Sea running via undersea cables that can be snapped by subs.
Wind power alone cannot power the UK, no matter how much of it we install. And I think ultimately storage to mitigate wind variability will not be practical. We will probably need to deepen our interconnectivity with other markets in order to make wind economical, which will always lead to the scarcity issues in times of crisis.
In a sense we have pushed too far forward with wind and left other power sources behind. Nuclear for example really needs to be pushed forward for baseload, we could be doing a lot better with solar (solar is beginning to ramp up again now) and we need more interconnectors to mitigate over/under supply rather than just building more wind power.
Wind is no more "free" than nuclear is. For offshore wind the installation cost is enourmous - the turbines are truly gigantic.
Maybe we should also post snapshots of the UKs power generation when the wind isn't blowing to see what that is like. Just for balance.
