As I see it, to prove that, it would be necessary to have sensors at all locations (or at least a large number of locations) where it would be reasonably possible to have wind and solar power installations. The data would have to be transmitted, in real-time, to a central location where it would be continuously analyzed to see how much power would be available reliably with no interruptions. So far as I know, that has never been done.

Imagine using only the energy from the sun to power your home. You would never have to pay an electric bill again and or be impacted by power outages.  It may sound great, but there are numerous advantages to having a solar home that is on-the-grid when available.

As fuel cell technologies are developed, hydrogen-powered vehicles are receiving more interest. The hydrogen economy, particularly hydrogen-powered vehicle penetration into the Korean transportation market, is studied in this paper. Market share was predicted using the currently available data. The results showed that the hydrogen era will not be as bright as predicted by many people. The main barrier is the fuel cell cost.

"On 1st February 2008, the Isle of Eigg entered a new era, with the switching on of our island electrification project, which makes 24 hour power available for the first time to all residents and businesses on the island. Until then we were entirely dependent upon making our own power and the clattering of generators was always to be heard. Now, the generators are silent and suddenly we have leapt to the forefront of electricity generation using renewable energy resources. Our project is a world leader in the integration of multiple renewable energy sources into a grid system to supply an isolated and scattered small community. "
