* Cows produce methane, cars produce CO2. Talking about "pollution" just muddies the waters. According to https://ourworldindata.org/emissions-by-sector https://ourworldindata.org/emissions-by-sector lifestock produces 6% of greenhouse gases, road transport 12%. Also looking at Germany (I don't have data for all of Europe), drinking milk production fell by 7% in one year (replaced by plant based milk) https://www.destatis.de/EN/Press/2022/05/PE22_N034_51.html https://www.destatis.de/EN/Press/2022/05/PE22_N034_51.html . Beef production fell by 2.4% (https://www.destatis.de/EN/Press/2022/02/PE22_050_413.html https://www.destatis.de/EN/Press/2022/02/PE22_050_413.html ) So changes are happening in agriculture as well.
* Supertanker emit a lot of soot, not so much CO2. Again: Talking about pollution in generic terms does not help. Also supertankers won't be needed anymore, if no oil is consumed. So electric cars will help with this as well. Replacing all fossil fuels would remove need for 40% of all tonnage shipped worldwide.
* Sweden and Norway already have basically completely renewable electric grids. Germany is exiting coal by 2038 (this will hopefully be accelerated to 2030). Every year some of the existing coal plants are being shut down: https://www.bundesnetzagentur.de/DE/Fachthemen/ElektrizitaetundGas/Kohleausstieg/start.html https://www.bundesnetzagentur.de/DE/Fachthemen/Elektrizitaet...
* No new gas heatings will to allowed to be installed in most EU countries by 2025. Heat pumps are already the default in Scandinavia and will be in other countries soon.
* Hydrogen production is being ramped up: https://www.rechargenews.com/energy-transition/germany-s-first-major-hydrogen-hub-uniper-to-supply-salzgitter-steel-plant-with-green-h2/2-1-1171937 https://www.rechargenews.com/energy-transition/germany-s-fir... or https://www.spglobal.com/commodityinsights/en/market-insights/latest-news/electric-power/090221-h2-energys-1-gw-danish-green-hydrogen-project-to-supply-trucks-stations-industry https://www.spglobal.com/commodityinsights/en/market-insight... to replace gas usage where electricity does not work.
So a lot is happening in all sectors. And you can see results: https://ourworldindata.org/grapher/co-emissions-per-capita?tab=chart&country=FRA~DEU https://ourworldindata.org/grapher/co-emissions-per-capita?t... This is not just virtue signalling.
- mantas 4y agoSweden and Norway are lucky to have long chain of mountains to run hydro. Scandinavian hydro won't power everybody's electric cars...
- nmehner 4y agoThe average car in Europe drives 30km a day and is parked more than 23h. So a charged battery will have a moving 10 day window to be charged again. This is a great use case for renewable energy. 10 days of Dunkelflaute does not happen a lot. Smart charging for cars will stabilize the grid.
- iso1631 4y agoUK, Ireland, France, Denmark, Netherlands, Belgium, Spain, Portugal, Italy, Greece and Cyprus are lucky enough to have vast areas of ofshore wind and tidal capacity. Morocco, Libya, Algeria have vast areas of desert ripe for Solar which can be exported via HVDC under the Med. France seems competent enough to be able to build and run nuclear power at an affordable level, they could expand that ability to the rest of Europe
- mantas 4y agoWind and solar will go stale once in a while. Tidal may be stable enough I guess. Nuclear is the only, well, nuclear solution
- iso1631 4y agoUnlikely that wind drops in the north sea, bay of biscay and med at the same time. Nuclear also goes stale once in a while, when plants are taken offline for maintenance. Solar is predictable, it generates in the day (when demand is highest), not at night. With connected vehicles you have massive battery banks of power that can be bought back from people, and as you've used the excess energy when you have been producing more than the demand from those resources to create green hydrogen, you reverse the process.
- mantas 4y agoAverage yearly wind won't drop. But it may slower for a day or week. Unless you want to stop some parts of society for that time, you'll have issues. Same for solar. It's not predicatable on day-by-day bases. With using cars as battery banks, even if you skip the problem of having cars connected all the time, you'll need to redo grid in a big way. Both to fill simultaneously cars if cheap solar energy hits the grid and keep the grid going on a stale cloudy day.
