Can USA get along with tarriffs on Canadian fossil fuels?

A recent speech by Trump said, we don't need Canadian energy, "we can produce our own."

I realize that northern parts of USA get much of our natural gas, for heating, from Canada. How fast can we ween ourselves from Canadian fossil fuel and build heat pumps for heating? I don't think that's what Trump has in mind.

I can elaborate more. Much of the US natural gas production is in different areas than the customers with no currently operating pipelines to connect. Pipelines can not be "built in a day", unlike Rome; as the old story goes. This takes time and patience, if it's a good idea anyway, in the era of climate change. I assume that climate change can't be waved away by a magic wand either.

At WWU, there is lots of talk about converting the system from natural gas to heat pump technology.

I would guess that makes lots of sense as a campus is already used to underground utilities so they should know how to install a system of "Earth to heat pump" technology.

Still it can't be built in one day.

Natural gas burns somewhat cleaner than gasoline that's made from oil. It burns cleaner than coal, but it's still a fossil fuel. Water is it's main "smoke" because it has more "hydrogen" and less "carbon" than other hydrocarbons; like oil.

I do find science interesting.
