Incompetent leaders aside.The Greens if ever in power would run this country into the ground.
They have no clue what the hell they're doing.They'd leave us defencless with no full time military,No nuclear weaponary,They'd leave us powerless and dependant on the weather to run our homes and cities and put us back into the dark ages and god only knows what would happen to our infrastructure and transport.
They are dreamers with no experience of running a country and no clue how to do it and i suspect with any luck most of their insane ideas would fade away one by one as reality set in.

The weather is the one constant... sun, wind, tide.

For residential power what's the problem?

It's unpredictable,unreliable and takes up huge amounts of land and probably money to harness enough energy to power even one city,Nevermind a whole country.
I've seen those wind turbines in the sea and they look awful and you need hundreds if not thousands of them to generate relatively little power.
The beaches and countryside would be littered with the things.
Not here for the lights flickering on and off whenever the weather is'nt behaving as we hope.
Nuclear is the only realistic constant reliable energy source for now but i'm gonna bet the Greens don't subscribe to that view.

I did say residential.. I don't see what's wrong with solar.
I don't subscribe to that either, nuclear+ fracking= death.
