Curious to know does 65w fast charger consumes more electricity?
65 Watt itself is a measurement of how much electricity that charger takes at maximum while charging once or twice a day for say about 1-1:30 hrs total. This is false. One watt is equal to one Joul per second. But it''s instantaneous power, time doesn''t really mean much there. For power over period of time, Watthours are used instead.
Electricity Calculator
One kilowatt-hour is equal to the energy used to maintain one kilowatt of power for one hour. Generally, when discussing the cost of electricity, we talk in terms of energy. Energy (E) and power (P) are related to each other through time (t): P = E/t. E = Pt. Electricity is most often measured and paid for based on the number of kilowatt-hours ...

What happens to excess energy fed into the power grid?
Most decentralized power generation - non-commercial solar panels, wind turbines and the like - happens at the house level, i.e. it produces 115/230VAC and pumps it into the mains supply. Most of the time this is fine because power generated is much less than power consumed and the net energy flow is still in the right direction.
