The only unproven tech I included is wave generation.

Renewables cause no more logistical switching nightmares than do fossil fuel and nuclear plants going off and on line, demand suddenly appearing and disappearing. In fact, it's a lot easier to incorporate wind and solar than deal with an abruptly disappearing nuclear plant like we experience a few times each year. Wind and solar ramp up and down slowly if you've connected input over a wide area.

We can build a renewable grid in a lot shorter time frame than 50 years and end up with cheaper electricity.
