Too many megawatts in one unreliable basket. Solar and wind can help -- especially where they can compliment each other (stormy days help wind power production but hurt solar power, sunny days help solar power but may hurt wind power production), but they shouldn't be relied upon for large proportions of the base load.

Numerous nuclear power plants are great for massive base load power.

There’s some new battery technology in the offing that will help. In fact, creating effective storage for the energy generated by wind or solar is one of the major problems they need to overcome.

Welcome to the rat energy future. The glorious sun and wind will supply all of our energy. When there is a failure, just blame it on global warming.
