Alternative energy just isn’t anything but a partial player in the energy production market and a small part at that. The sea erodes granite cliffs what chance have we got of producing anything that isn’t high maintenance and therefore high cost. Wind turbines are killing bats i read somewhere and again high maintenance. Geo thermal… we aint got none, hydro electric.. small scale in scotland maybe.. oil and gas .. it will run out… nuclear…. ok but thousands of yrs before the “waste” is safe. Leaves coal .. unfortunately Maggie made sure thats going to be expensive if we want to go back to it
