About the investment, sorry but wrong question. It´s not where is this going to come from, but where is this coming from. Most countries are investing in renewables and increasing their percentage in their electricity production for many years now, so in the future it will come from the same place it´s been coming from these years, the same place as any investment of any goverment, our wallets. Nothing is free, if you want something, you must be prepared to assume the cost.
"Energy use in the United Kingdom stood at 2,249 TWh (193.4 million tonnes of oil equivalent) in 2014. This equates to energy consumption per capita of 34.82 MWh (3.00 tonnes of oil equivalent) compared to a 2010 world average of 21.54 MWh (1.85 tonnes of oil equivalent). Demand for electricity in 2014 was 34.42GW on average (301.7TWh over the year) coming from a total electricity generation of 335.0TWh."
The UK's total energy demand - that's everything that has to be replaced to become zero emissions - was 2,249TWh. Our generating capacity was 335TWh. That's a little over 6.7 times the demand than the supply is able to provide. So if the UK is to go zero emissions, we have to provide nearly 7 times our current generating ability with renewables. Our current renewables is about 20-35% depending on figures used. So we have to increase our renewables generating capacity by 20 times (assuming current is 35%)! And our current grid is close enough to capacity to make no difference, and it's old. So we need to replace all of that too, 21 times (20 new times plus replace the existing).
That's the reality of going zero emissions a.k.a. pollution free. And that's why it won't happen in my lifetime. Or, if I had any, my children's lifetime.
So please, enough of the dreams. The sad reality is that pollution is not going away in a hurry.
