Can renewables produce as much power as fossil fuels in the uk?

So the UK not one of the sunniest places in the world most of our renewables come from wind

Now we have more wind farms than gas power plants. 780 wind farms vs 55 Gas power plants

If we didn't have those Gas power plants the UK wouldn't be able to keep up with demand. How many more wind farms would we have to build before we can get rid of gas power completely? Plus wind farms only work when it's windy vs Gas which works 24/7
