The cost of refueling a Tesla is more affordable compared to filling up a gas-guzzler’s tank, but actually, there is no fixed price because this relies on a number of aspects such as electricity, how you charge it, and your model of Tesla. Take charging at home, for instance; the average will be around $10 to $15, based on the average rate of power in the United States that is $0.13 per kWh. The overall cost varies according to the size of your Tesla battery, usually between 50 and 100 kWh, and local tariff.It costs about $0.25 per kWh to charge at a Tesla Supercharger. Most will be less expensive than home charging and typically more costly than home charging, depending on the type and location of the Supercharger, so the full charge is anywhere from $20 to $25. Home charging may be a little more expensive if it gets the electricity from pricey places, like parts of California or New England, but when it comes to fuel, it can still keep costs down significantly, especially for those who charge by using renewable energy sources such as solar panels and off-peak electricity rates. Overall, charging a Tesla is not only cost-effective but also helpful to the environment, so this would be the smart choice for saving money and at the same time reducing emissions.
