Hundreds of billions of public money spent on “alternative energy” research by the federal govt over the past 40 years and we have almost NOTHING to show for it. The “rightful place” is for the private sector to perform most of the R&D and get the federal govt with its statist “industrial policy” goals out of all R&D.
What have we got to show from them?
Basic scientific research is usually not funded by the private sector because there is no immediate ROI.
I don't know the details of where the government may have put money into "alternative energy" aside from fusion research. I do know that we wouldn't have a biotechnology industry in this country without many years of federally funded research.
To do the most fundamental forms of research, somebody has to commit to it who is not expecting to necessarily make an immediate buck from it.
