Nothing can compete with renewable energy

4. First, not talking about behind the meter.

Behind the meter is almost totally incapable of fulfilling clean energy needs on a large scale. We need the large energy companies to adopt clean energy, not just Joe Blow with his house roof solar panels or Hugo Bigfactory Company.

Last I heard, pumped hydro efficiency has approx 80% efficiency. Plus, it can be added onto existing infrastructure with existing technology which is a huge advantage. Storage batteries don't come even close to that efficiency and require rather new infrastructure and tech that has yet to be built into the grid.

Forget hydrogen. Generating it is a huge energy sink.

Just pump water uphill. Easy Peasey! 80% is pretty damned good. Plus, there are lots of places where much of the infrastructure is already in place.
