There are nuclear options that dont involve radioactivity.

And the algae option seems great.

In the last 6mo I have flown from San Fransisco to Albuquerque many times. There are VAST stretches of land in which you see not a single house.

There are options. It is just obvious that we are not at the point in which we must research and implement them.

Solar IMO is not the option though. It has been known for along time that it takes more energy to produce the panels than they get out over their lifetime. But that is just the current technology. That doesnt mean that energy from solar is not plausible, just not in its current form.
