Electric car


Electric motor efficienty is 98%. Combuston engine’s efficienty is 60%. Electric cars in Poland aren’t ecology. In majority electric power station make a fire a hard coal. In this efficienty production’s is very small. First coal is burn in boiler. Next, turbine change sales in electric current. In Poland power plant’s efficenty is from 30% to 43%. Total efficienty electric car’s is 29% Combuston car is twice doubly more ecology to electric car.
