Few places have enough elevation and water for hydro (and don't mind submerging loads of land to make it happen).
For almost all countries - experts (engineers and scientists) have been warning grid and production will not be enough, and politicians kept focusing on shorter term wins of votes.
The long view is critical so I looked at the solar install costs against the retirement cash flow needed to pay for energy.
My first install has got to be over 10 years old by now and has been completely trouble free. I have sold SRECs in that time that have almost paid for the system. I only receive an electric bill in the winter(heat pumps). I also received text incentives at the time. I feel like now I'm in a position where my only costs will be replacing failed components. These components replacement costs will be a fraction of the original install and will perform better.
The installation is unfortunately also grid-dependent, so it's useless when the power goes out.
