Wind and solar are (largely) the future because of cost, reliability, sustainability and off-grid potential. We should have phased them in with nuclear 20 years ago, until we sorted out energy storage issues for a 24-hour cycle. I believe it's too late now for nuclear, because by the time they are built their tech won't be cost-competitive. Batteries are great for grid stabilisation now, until gas can kick in, as we rethink what an electricity grid is and how it should operate.
In the next ten years I suspect there will be a breakthrough in storage, much like the way computer chips massively increased computing capacity over a decade. That will be the gamechanger.
