Electric vehicles convert about 60% of their energy to propulsion. Conventional cars, on the other hand, are very inefficient.
For every litre of fuel burned, only about 17 to 21% of the energy is converted to forward motion, the rest is lost as heat and noise. The waste heat collectively warms up urban areas, causing more use of air conditioning in buildings in summer.
And buildings located near heavily trafficked roads may be exposed to high air and noise pollution, so windows may not generally be used for ventilation. This also places demand on air conditioning and electricity.
