Except that diesel emissions kill city residents.
- StreamBright 7y agoSo does coal power plant emission.
- munk-a 7y agoI don't mean to suggest that power generation modernization isn't important but... it's pretty beside the point, investing in diesel buses is locking that usage in for a great many years while an electric bus may be eventually powered by coal initially then transitioned over to an alternative energy source.
- merpnderp 7y agoI’d argue for diesel buses because wind and solar already strain keeping the electric grid stable, except it won’t be a coal plant, it will be a natgas plant, which by itself is a huge win over diesel motors in a big city.
- deagle50 7y agoAre you really comparing pedestrians inhaling NOx directly from tailpipes to a remote power plant?
- sokoloff 7y agoIsn't it the particulates in diesel emissions that are particularly more harmful than other internal combustion engines? NOx promotes low level ozone, which is an irritant, but I thought by far not the differentially harmful portion of diesel exhaust.
- StreamBright 7y agoYes I do. https://ourworldindata.org/co2-and-other-greenhouse-gas-emissions https://ourworldindata.org/co2-and-other-greenhouse-gas-emis... https://ourworldindata.org/grapher/carbon-dioxide-co2-emissions-by-sector-or-source https://ourworldindata.org/grapher/carbon-dioxide-co2-emissi... https://blog.mybacharach.com/articles/sources-nox-emissions/ https://blog.mybacharach.com/articles/sources-nox-emissions/ I know your feelings is as good as data but still.
- gataca 7y agoCentralized coal power plant outside of the densely populated areas that buses concentrate in >>>>> mobile pollution machines in those same dense areas. Seems rather obvious
- StreamBright 7y agoVolume of coal power plant >>>> mobile pollution machines. The 7 out of the top 10 CO2 emission sources in Europe are coal power plants. Their production is blown by the wind to populated areas. Some of coal power plant production ends up different countries as well. https://www.theguardian.com/environment/2013/oct/15/european-cities-dangerous-air-pollution https://www.theguardian.com/environment/2013/oct/15/european...
- r00fus 7y agoSo add solar+wind into your jurisdiction's power mix. It's not hard to do, and progressively the diversity of power will be more stable than just relying on the coal plant which will get shut down. EV buses allow you to wean off carbon power sources in many stages.
- StreamBright 7y agoSorry I would like to run buses when it is dark or when the wind is not blowing.
- Brometheus 7y agoWell, they run on batteries.
- StreamBright 7y agoI see, how long they run with one charge? Are you implying that worst case the buses are charged with nuclear or coal energy?
- imtringued 7y agoI am speechless.
- StreamBright 7y agoSorry if you have nothing to add here.
- dang 7y agoCould you please stop posting unsubstantive comments to Hacker News?
- StreamBright 7y agoLike what exactly?
