There was never any doubt about the magnitude of these, the challenge was always in harnessing them so as to meet demand.Today we are well advanced in meeting that challenge, while also testing the practical limits of doing so from wind and solar (variable renewable energy, VRE).But attention swung away from renewable sources as the industrial revolution progressed on the basis of the concentrated energy locked up in fossil fuels.

I further assess the appropriability of experience by considering the transfer of knowledge within and across firms.
Results suggest that generation experience on a particular project leads to higher productivity at that project but not at other sites.
Using detailed atmospheric data to account for potential output, I study whether generation and installation experience leads to increased productivity for solar and wind projects.
While this phenomenon is often cited as a rationale for subsidizing renewable electricity, there is relatively little project-level evidence on how knowledge is accrued.
However, the variability of wind and solar power does not correspond with most demand, and as substantial capacity has been built in several countries in response to government incentives, occasional massive output from these sources creates major problems in maintaining the reliability and economic viability of the whole system.
There is a new focus on system costs related to achieving reliable supply to meet demand.
Another relevant metric is energy return on energy invested (EROI).
This is not quoted for particular projects, but is the subject of more general studies.
A fuller account of EROI in electricity generation is in the information paper on Energy Return on Investment.
The (WEO2016) makes the points that VRE have five technical properties that make them distinct from more traditional forms of power generation.
