U didnt mention about real problems in UK! A midday gap, the high price of turbines and solar depending on gas power plant or hydro, nuclear. As you know gas nuclear generators are inflexible they just cant simply slow down or get faster to balance power in grids. Please read the fundamentals of Electric-Techical  theory. And you also didnt mention about killing birds and bats, and because of vibration under the ground of wind turbine there is no life. Too much territory using but the output is so ridiculous. And in the end customer pay for everything.
