Con Edison’s request to hike electric bills 4% — and gas bills 7% — each year through 2025 is just a small taste of what New York’s green-energy mandates will cost the public.

These added revenues are only for work on the transmission grid to handle the shift to more “renewable” sources of power, which means connections to where the wind and solar plants will be, plus to planned battery backups since neither source is reliable.

Oh, and to bribe customers to switch to the electric heat and other devices the state’s climate plan demands.

Future rate hikes will be needed to address the fact that solar and wind cost more than fossil-fuel-generated electricity.

And it’s not just ConEd: Last month, National Grid proposed a hefty 17% increase, blaming inflation as well as the state’s climate targets.

Again, low cost estimates for the state’s Climate Leadership and Community Protection Act run past half a trillion dollars, and Albany isn’t reducing its other outlays to cover that from existing taxes.

And nobody builds and runs this stuff for free: Consumers will get the shaft.

Nor will the climate warriors offer any choice: They’re closing off other options (no new natural-gas pipelines! Shut down “unneeded” gas and even nuclear plants!), with zero guarantees enough “renewable” sources will actually get built in time.

As we’ve said before: It’s inevitable that this madness will eventually collapse as the sheer impossibility of it becomes unmistakable.

The only question is how much money will get burned, and how much damage imposed, before reality sinks in.

In the meantime, it’s going to be a bumpy, expensive ride to chase green energy nirvana.
