China is embracing solar and bringing down price of panels.
Hopefully we will see an increase in reliable and scalable renewables and a decrease in nuclear and fossile fuel dependency.
Solar seems very promising. The Ivanpah plant produces about 40% of an average nuclear reactor at its current size.

Nuclear Fusion seems a ways off and promising output. However, I think there may be much higher dangers than currently advertised ( explosion or something else ).
We know nuclear energy isn't efficent with it's approximate 10% utilization and we're already past the half-way mark for world uranium deposits. And even with new waste reprocessing theories we still have a lot of that to contain, not to mention how seriously dangerous it is and how much leaks out through standard procedure let alone disaster.
Valid questions indeed.
