1. We ought to build a giant solar power desalinization plant in Southern California. Convert Seawater into drinking water, salt and electricity. It would use solar reflectors to boil seawater and create steam. That steam would be used to drive turbines and create electricity. When the water cools it condenses into pure H2O and salt. The water would be sold to people for drinking, washing, watering livestock and watering plants. The salt could be sold or returned to the ocean if there are not enough customers... Camp Pendleton near San Diego would be an ideal location. Southern California is in need of water. There is a current proposal to use pipelines to move fresh water from the Sacramento River to be used by farmers and residents in SoCal. An alternative would be to just get the water from the ocean... We should also stop watering lawns in California. It's a cultural norm that is not practical in a state that is suffering drought. What if it became fashionable to have rock gardens or cactus? That's what they do in Arizona...
2. Convert human fat into electricity using exercise bicycle power generators. The kinetic energy created by people pedalling can be converted into electricity by using an alternator, diode and battery. Many people use stationary bicycles for exercise and these currently unused sources of power could be used to create electricity. People could sell the electricity to the power company.
