We need the energy in 15 years as well, maybe even more than we do today. Renewables is just a fancy term for "energy whenever the sun shines or the wind blows". This is factually not always the case. We need energy that is available regardless. And that's where fossil fuel and nuclear excels. Fossil fuel's downside that it kills ~3 million people per year. Nuclear's downside that it scares (not kills) ~3 million people per year.
