No, because the supply requires sufficient capacity and diversity.
I think you are mistaking ehat i am posting as my opinion, when i am simply summarizing the current industry state of the aet and the models created by energy department and research institutions across the world..
You are advocating it though, wind already accounts for around 1/3 of UK generation so any more doesn't satisfy diversity. You don't believe in nuclear and you see it as feasible that it can be done with only wind, solar and batteries? How do you propose to make up the other 15% currently from nuclear and 35% from fossil fuels (mainly gas) with a bit more wind and solar (at this latitude)? Going 40% wind, 40% solar or any other combination of this is not diverse at all and will lead to problems unless you over spec everything by huge margins and spend inordinate amounts on batteries.
