Quiet
Electric propulsion systems typically run very quietly compared with combustion engines. A combustion engine works by essentially causing many tiny fuel explosions, which provide energy but also create loud noises. An electric propulsion engine that takes its power from batteries or some sort of device like solar cells has very few moving parts and has no need for loud combustion to generate propulsion. Vehicles with electric propulsion as a result run on a much quieter level than combustion propulsion vehicles.
Sustainable
Electric propulsion vehicles may generate their power through sustainable energy. Combustion engines require fossil fuels, particularly oil, to generate energy for propulsion. However, oil supplies on the planet are finite. An electric propulsion system, on the other hand, could use electricity generated from solar cells to generate electricity. As long as the sun shines, power can be generated, and so electric propulsion systems do not have to rely on expensive or rare fuels for power.
Clean
Electric propulsion systems themselves generate little to no pollution. An internal combustion engine will release large amounts of carbon dioxide and carbon monoxide into the air as a byproduct of the fuel it burns. This and other pollutants damage the earth's ecosystem. Electric propulsion, on the other hand, requires no fuel burning. As a result electric propulsion can be a very clean alternative to combustion.
Multiple Sources
A battery-powered vehicle could use essentially any available power generation source as long as it contributed to the power grid the vehicle plugs into. So, rather than simply rely on oil, an electric propulsion vehicle could use power originating from various sources: wind, solar, hyrdroelectric, nuclear, natural gas or coal power plants. This means that even if power generation shifts with technology, an electric propulsion system could still work unchanged.
