Renewable energies are attractive, because we would like a free lunch--effectively a perpetual motion machine that gives us all the energy we want, with virtually no inputs.
Unfortunately, in the real world, such free lunches don't exist. Using fossil fuels, we can add on devices of various kinds to our existing fossil fuel infrastructure, and call them "renewable." In fact, they may operate as long as the system itself operates, if they get an adequate supply of of spare parts and other types of maintenance, again using the fossil fuel system.
What the economy really needs is "cheap to operate" devices which extend our fossil fuel system. The use of these "cheap to operate" devices needs to help generate tax revenue for the system--something they are not doing now. Instead, they too often need subsidies--something that by themselves prove that they are a drain on the system. High priced alternative vehicles are another drain on the system, because they effectively require the poor to subsidize the rich through subsidies.
If our current system were not on the edge of "breaking," perhaps these issues would not be important. Unfortunately, we are dealing with a financial system on the edge fo collapse (young people who cannot afford to get married and buy homes; endless stimulous policies including zero interest rate policies blowing stock market bubbles; many businesses whose best investment is buying back their own stock). "Renewables" tend to make our current collapse-prone situation worse rather than better.
If renewables can "pay their own way," I am all for them. Otherwise, they are just an excuse to use more coal and other fossil fuels to make devices that look like they are helpful for the long term.
