E-bikes are criticized by traditional bickers as somewhat in between a car and a the common bicycle. It is clear that they do not pollute as much as a car, but neither do they use they only the energy of your legs. Rather, they need electricity for a propel functioning and all depends on the pool of energy the electricity comes from. For example, if you live in a country where all the energy is produced by renewable energy, that is OK, but if your country generates 20% of it from green sources and 80% from pollutant origins, then the e-bikes are not so environmentally friendly as one can thought. Still, it is better than a pollutant car, and environmental activism should be done to contribute to the change of the energy sources in the last country.
Some figures I have found on the carbon footprint related to e-bikes are the following:
– 75% is generated in the production process
– 15% goes to the batteries charging
– 10% compromises logistics, packaging and the recycling of the e-bike at the end of its life
– The carbon footprint of an e-bike is around 14 CO2 grams/km. Compare it with 150 CO2 grams/km of a car or the 60-80 CO2 grams/km of the public transport
Moreover, an e-bike consumes about 7 Wh. If a 500 Wh battery is incorporated to the same bike, it can travel more than 80 km. For a comparison purpose, this energy cost is similar to a microwave working for 30 minutes, a computer for 2 hours or a refrigerator for 60 minutes.
Besides, the cargo e-bike allows transporting impressive loads from common shopping to a piano. Indeed, more a more parcel deliveries are using them in what is called the last mile delivery which is usually done inside cities and villages.
