> So... If the article is correct, and electric energy costs 77% more than natural gas,

If you use resistive heating, heat pump would be 40-50% or so cheaper. Of course with no subsidies the initial cost might be rather high.

I'll ask my landlord to install one right away.

Probably have to be an earth-exchange system to deal with temperatures lower than 40°F, given that heating my house in winter is the use case.

My Mitsubishi Hyperheat units have a COP above 1 down to -15F and still work normally at 5F (northern New Mexico, 6000', overnight). You're getting bad information.

Mitsubishis can work down to -13F/-25C and have a COP of 2.08:

If you live in US IECC Climate Zone 4 or above look for a cold climate air-source heat pump (ccASHP):

You can also get things installed in a dual fuel arrangement where you still have a gas furnace that kicks in if it does ever get 'too cold'.

My Lennox system is break even COP at -10 iirc. By then it's also running the heat strip, but we only hit those temps once or twice a year.
