Solar doesn't provide energy in the evening or nighttime, wind is unpredictable and hydro involves environmentally damaging waterway modifications. The end result is that fossil fuels and nuclear will always have a place on the grid.
The worst thing we could possibly do is to start installing solar cells on each individual house, while trying to maintain our current consumption. The challenge is that there is a profitable multi-billion dollar market selling grid-tied personal solar and wind power systems to millions of eager Americans, but that approach would be woefully inefficient (several thousand dollars worth of electrical hardware installed in each house across the nation, a glut of home-generated electricity during the day as everyone attempts to sell surplus back to the grid).
Instead, it's time to look at how we're using electricity. Stop building chipboard McMansions that require excessive A/C and heating. Increase the energy efficiency of appliances. Try living in smaller spaces. Discourage people from trying to build cities in the middle of scorching hot deserts, And so on.
