As the cold drops their capacity sharply, at the same time the drain from heaters etc shortens range even more? Maybe you should talk to someone who has actually tried using batteries in cold weather. ice engines also experience a significant drop in efficiency in cold weather as well. 2 Quote Link to comment Share on other sites More sharing options...

Making long trips very problematic. Especially, as Alf points out, in a place like Canada with extreme cold weather and really big distances to cover. While it’s not perfect technology yet and does have certain limitations it is still workable even in cold climates. Pre-condition batteries in cold weather (plug them in at home as you do with a bock heater on ICEs), use heated seats and steering wheel, and if you need to use the cabin heater leave the fan as low as possible. Not only is Norway making it work with EVs their large trucks will all be either electric or Biogas by 2030, if not sooner. https://www.fastcompany.com/91011373/evs-work-fine-in-the-cold-in-norway-heres-how-they-do-it https://www.electrive.com/2023/12/04/new-trucks-in-norway-only-allowed-with-electric-or-biogas-drives-from-2030/ 1 1 1 Quote Link to comment Share on other sites More sharing options...

They tend to work better in higher population densities, and are not practical in various situations. For example, most of those zero emission trucks in Norway will not likely be using huge batteries, they will be more likely to use hydrogen fuel cells, which are much more practical for heavy load/long distance applications. FCEVs can be greener than BEVs, depending on how you produce the hydrogen, since FCEVs need much smaller batteries which are usually pretty toxic to produce. 1 Quote Link to comment Share on other sites More sharing options...

Boudrias Posted January 26 Share Posted January 26 Very interesting uTube about Rondo Corp. development of concrete bloc heat storage systems. Wind and solar electricity converted to heat and stored in concrete bloc. Claims are this can reduce global CO2 by 15%. Overall cost per KWH is less than existing grid cost. 2 Quote Link to comment Share on other sites More sharing options...

Satchmo Posted January 26 Share Posted January 26 (edited) All hell for a basement and now they're working on the roof... Alberta's oilsands pump out more pollutants than industry reports, scientists find Alberta's oilsands operations produce far more potentially harmful air pollutants than are officially reported, with the daily output on par with those from gridlocked megacities like Los Angeles, new research suggests. The study, published today in the academic journal Science, measured concentrations of organic carbon emissions in the air by flying overhead and taking samples. Those numbers were compared to estimated amounts, prepared using ground-based data, reported by oilsands operations. The researchers from Environment and Climate Change Canada (ECCC) and Yale University found levels that were between 20 and 64 times higher than those reported by industry, depending on the oilsands facility. https://www.cbc.ca/news/science/alberta-oilsands-research-emissions-1.7093626 Edited January 26 by Satchmo 1 Quote Link to comment Share on other sites More sharing options...

the destroyer of worlds Posted January 30 Share Posted January 30 Deniers: why bother doing anything cause China. China is set to meet their 2030 targets years early. They currently have 40% of the world's installed solar. They are a few short years to having one terawatt of installed solar capacity.

Satchmo Posted February 5 Share Posted February 5 Has the planet warmed more than we thought? Ocean sponges might be telling us something A handful of centuries-old sponges from deep in the Caribbean are causing some scientists to think human-caused climate change began sooner and has heated the world more than they thought. They calculate that the world has already gone past the internationally approved target of limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times, hitting 1.7 degrees (3.1 degrees Fahrenheit) as of 2020. They analyzed six of the long-lived sponges — simple animals that filter water — for growth records that document changes in water temperature, acidity and carbon dioxide levels in the air, according to a study in Monday’s journal Nature Climate Change. Other scientists were skeptical of the study’s claim that the world has warmed that much more than thought. But if the sponge calculations are right, there are big repercussions, the study authors said. https://apnews.com/article/climate-change-warming-sponges-caribbean-391ee1bb3dabb0496f0f2848849418b6 Quote Link to comment Share on other sites More sharing options...
