Fossil fuel use continues to expand even as "green" energy expands. Nuclear energy is the only energy that can be upscaled to meet future demand and additionally is the only one that can expand base load requirements. For every new Wind turbine or solar panel, comes a requirement to duplicate that capacity with something to guarantee the base grid requirements can be instantaneously met. The problem with the grid is, like green energy itself, you cannot store electricity in sufficient quantity to cover the times the wind dies or the sun does not shine. The only instantaneous source is gas, coal, or nuclear....and, when the conditions are right, hydroelectric, which again, cannot provide more a few percent of our needs.
