> Every Tesla on the road today is effectively a coal powered car
Assuming that your energy is entirely produced by brown coal power plants, then even powering your electric car is still more efficient (and thus cleaner) than running a petrol car.
Power generation sources varies wildly depending on region - Nuclear, Gas and Hydro are big contributors in many areas. Wind and Solar in others.
> losing 1k on every car sold
you're conflating the profit on selling cars vs company profit. They make a profit on the sale of each Model S/X, they're investing a lot of money into expanding production.
The IEA/OCED world energy production sources for 2015 [1]J:
41.3% Coal
21.7% Natural gas
16.3% Hydro
10.6% Nuclear
5.7% Other
4.4% Oil
Additionally, you could also invest in a solar setup at your own house and Tesla is working on converting Supercharger stations to solar [2].
