Yeah, clearly over simplified but the point being that nothing in my house has had to be modified in anyway for it to shift from being 100% powered by coal to 100% powered by wind. The changes can happen without involving "the public" at all which make it a gazzilion% easier.
The government policies to get people off natural gas are going to seem much more interventionist, hence reluctance from politicians to make any actual decisions.
It absolutely is. It would also absolutely be achievable, but there would need to be a fundamental attitude change along with things like big investments into carbon neutral public transport, while cars are being banned and taxed to high heaven left right and centre. I can't really see it happening realistically, but I won't give up hope we can at least vaguely move in the right direction.
As a side note:
That part is easy, yes, but electrical / power engineers will tell you that the distribution of power in itself is a super complex thing, and getting it from many individual turbines vs one big coal power plant is not as straight forward as the slightly naive thinking of "well you 'hook it up' to the grid" that us non-electrical-engineers tend to have. Again, totally doable, but even that 'easy' bit isn't that easy when you drill down into it.
