Bought at .222 a couple of years ago. Apart from a warm fuzzy for doing my carbon emissions bit, I have serious doubts. Yes selling power to the grid is income in the short term, but the reverse hydro scheme for future income is very heavily dependant upon off peak and on peak price differentials. With e-vehicles charging overnight in coming years, a legislative change (or a corporate one) could kill the goose. IMO that is. Any others?
