Yes, because in the long term electric vehicles consolidate fossil fuel emissions to a single large point (coal in this case) which can be eventually replaced with a clean energy source (i.e. solar, wind, hydro, nuclear, etc.).
- jeffwass 8y agoAdditionally, the emissions of that consolidated power plant can be better filtered (eg particulates) than the corresponding thousands of disparate engines.
- solarkraft 8y agoIt's also not directly in the city.
- knicholes 8y agoThis is a big one. I live in Lehi, UT, in a place we call "Utah Valley." It's a bowl surrounded by mountains. When there's an inversion or when there's no storm to blow out the pollution, it sometimes reaches the top of the "worst air quality regions" scale. Moving the pollution to an area outside the bowl is a huge deal for me.
- baroffoos 8y agoAlso coal powerplants run much more efficiently than a car engine.
- adtac 8y agoIs there a statistical report on this? I'm not contesting your claim, I'm just curious to see _how_ much more efficient.
- christophclarke 8y agoInternal combustion engines operate at about 25% efficiency (per this paper, page 54) https://deepblue.lib.umich.edu/bitstream/handle/2027.42/57640/mpapke_1.pdf?sequence=2&isAllowed=y https://deepblue.lib.umich.edu/bitstream/handle/2027.42/5764... Coal power plants operate in the range of 34% efficiency https://www.eia.gov/tools/faqs/faq.php?id=107&t=3 https://www.eia.gov/tools/faqs/faq.php?id=107&t=3 https://www.eia.gov/electricity/annual/html/epa_08_02.html https://www.eia.gov/electricity/annual/html/epa_08_02.html
- baroffoos 8y agoAlso they tend to be run very far away so you aren't getting a blast of pollution to the face every time you go outside
- Rebelgecko 8y agoI wonder how much of that gets offset by transmission loss and the scooter's charging/discharging inefficiencies? Not that that would be a reason not to use scooters in and off itself, since they're be posed to take advantage of grids that will hopefully become more and more renewable over time
- beerlord 8y agoPlus transporting about 80kg of human, scooter and baggage is much less weight than human, car and baggage. It would be interesting to calculate the MPG of these, including the overnight recharging and repositioning done inside a van.
