Do New York politicians want to phase out the use of fossil fuels — or not?

On Friday, Assemblyman William Colton (D-B’klyn) blasted National Grid for turning away new Brooklyn natural gas service customers.

Without a gas pipeline recently nixed by Team Cuomo, the company says, it won’t have enough gas to fill new orders.

Colton and allied pols insist (dubiously) that National Grid can find other sources of gas. But why is he suddenly demanding greater use of the fuel?

After all, Colton cosponsored the state’s “Green New Deal,” which aims to do away with fossil fuels, like natural gas, and shift to a “carbon-free” economy. He should be overjoyed that a utility is ending new gas hookups.

The state, by the way, rejected the Williams/Northeast Supply Enhancement pipeline to Queens because Gov. Andrew Cuomo, too, wants to end fossil fuel use here.

That’s not the official explanation, but Cuomo has turned down other pipelines as well; each time, his folks cite “water quality” issues, because federal law won’t let states kill pipelines (which serve large regions of the country) for any other reason.

Yet their motives are obvious: No pipelines means no gas. That’s the point.

But that infuriates consumers. So pols like Colton point fingers at National Grid for doing what he and his pals . . . demand.

Politicians routinely try to shift blame for the consequences of their actions. But their constituents shouldn’t be fooled. And the Colton-Cuomo crowd should own the problems they’ve caused.
