The future is electric………….

[VNA]

The point is that renewable is not equal to "not damaging the environment".

I don’t disagree.  But right now the priority is that we decarbonise our economies – the environment and our future depends on it, but yes it must be achieved with minimal impact on the environment itself.

Getting half the electricity we need from the Sun alone is still not realistically feasible for all I know.

Scotland should be practically 100% renewable in terms of electricity in a matter of just a few years.  The next big challenges for us will be decarbonisation of transport and decarbonisation of our homes – ie heating. 
It’s all very doable.
