So what your saying is that given fuel makes up 3-5% of a commercial kitchen’s operating costs as per the Department of Energy, it would at worse add ten percent to the prices of kitchens that currently use natural gas instead of propane or electric? And that’s worse case, ignoring that Berkeley sure isn’t paying average kitchen labor costs given minimum wage there is nearly two and a half times the national average.
So all in all nowhere near a large enough price hike to kill all demand for large restaurants in the city even by the worst case figures of a company lobbying against it.
The US could do similar, but the Democrats couldn’t on account of all legislation in the last decade needing Republican approval to not get filibustered, and Republicans hating the idea of any subsidy that interferes with the “free market” outside of oil subsidies.
While the US government could absolutely be doing more in theory, in practice I think the climate legislation the Democrats have managed to get past Republican obstruction has been very impressive.
