I'm sorry that I don't know how to type in Chinese and am too lazy to comment through my iPhone. Everything you talked about is correct. Good job on your research. As an EV owner, I have seen a lot of EV advantages. You didn't talk about the energy recapture during braking, a.k.a regenerative braking. Let me tell a story. I did this several times. I drove my EV to a resort up in a mountain. At the bottom of the mountain, I had an EV range of 182mi. The elevation changed was 4,500 ft, and it took me 45 minutes to get up to the top. To be specific, it was about 56mi. When I returned to the exact location, my EV range was 187mi. If I drove an ICE, all this energy was lost both uphill and downhill. However, my EV recaptured all the energy back, plus more. Sounds unreasonable but true. Another example is when I drive in bumper-to-bumper road condition; my EV recaptured some much energy that I only used 10mi range to travel 40mi. If you are not an EV driver, you will never see this. If you take this into the energy efficiency calculation, I don't know how to determine the energy efficiency. However, this happens every day. By the way, if I drive at 75mi/hr, I will use 40mi range to travel this 40mi.
there are two distinct advantages of EV comparing to gasoline/diesel cars during use 1). no toxic gases (such as NOx) emission & 2). minimal heat generation. For a compact city such as Hong Kong, these advantages will reduce heat island effect, make the city more liveable & reduce adverse health impact. These in turn reduce overall social cost.
Just as well, there’s one distinct DISadvantage in using EV’s. Since there’s no EV factories here, the real cost is at the expense of manufacturing countries. But not really so thoroughly. Think the water people drink, the air they breathe where there’s no EV plants. Are these cleaner thanks to the use of EV’s? Try doing some research in environmental expenses where EV’s rule. No one shall be convinced thoroughly of the cleanliness of EV’s.
it depends on where the electricity is coming from. Any coal/oil power plant produces toxic gas but the power plant is far away from me, I don't want to smell it on the street. It still better than ICE cars. I agreed on your second point. EV efficiency is about 65%, ICE is 33%. 2/3 of the energy from gas car is converted into heat energy. That's why the engine is so hot. Research on line and you will see the numbers.
I’m afraid you are quite wrong! Some EV nowadays has cobalt free batteries, did you know petrol and diesel fuel also uses cobalts during refining process? You have also mentioned that the biggest pollutions is caused by power stations which could be powered by coal etc etc which in turn power an EV , but yet again you’ve failed to realised it takes absolutely enormous amount of electricity to process crude oil to petrol and diesel and then more pollution by transportation to local fuel stations. You have also failed to realised the efficiency of the EV is something like 80+ % compared to only around 30% for petrol. As for recycling, the battery packs from EV will be used as battery storage and I believe it’s approx 95% recyclable
EV seems to be another marketing strategy to have consumers jump on new products. I have once checked that an EV, due to the weight of the battery, on average weighs up to 3 times more than a conventional fossil fuel car, so in terms of energy efficiency, you can do the maths. a Hybrid in fact makes more sense.
you can check all the extra work they do with cobalt mining for batteries that don't last very long. Moreover, electricity is still generated mostly by coal or petro. So the extra battery only means more mining and destroyed fields.
At least for Tesla, long term cobalt will be eliminated entirely… furthermore, the 4680s have been designed with ease of recycling as the top priority. Nice that you mentioned Redwood Materials… hoping they will go public soon
@@kin9225 Yes, that as well... but the media's narrative has been on EVs and specifically Tesla mainly because Tesla doesn't spend a dime on advertising, while its major competitors (oil/gas/autos/utilities) do... ultimately, this results in a lot of misinformation and attack pieces on the industry

而且感覺妳的視頻似乎有誤導成份。
妳用了差不多1/4時間說鈷對我們的傷害，然後又把鈷跟EV電池連在一起。令人產生錯誤的結論。
但你沒有說其實實際情況不是這樣。
實際情況是，全世界絕大部分的電動車都是中國制造的大陸品牌電動車。而大陸品牌電動車絕大部分都不用鈷的！！
主要是西方國家和韓國用鈷。但他們的電動車在世界的份額只占少數。
（ 最新消息是連 Tesla 和 Toyota 都開始部分車改用 BYD（比亞迪）的電池了！所以其實鈷不只是少數而且份額不斷縮小）

機械工程師告訴你：內燃機引擎，把化石燃料轉化成動能嘅效率係33%
好!，現在比較一下電動車嘅效率如下：現在用100J嘅石化燃料通過蒸氣鍋輪發電機嘅效率係60%, 假設電廠去到充電站中途嘅損失暫時忽略不計，充電之後，電力轉化為動能的效率是40%，結果得出的就是26.4%。簡單算式如下 : 100J 的化石燃料 ->?渦輪發電機 -> 66 J 的電 -> 電池充電 -> 電能變成動能效率，40% = 26.4J
100J x 0.66 = 66J x 0.4 = 26.4J (比剛才的33%還要少)
所以如果要解決空氣污染和環保的問題，方法就是採用輕能汽車 (fuel cell) Toyota係二千年已經研究咗出嚟，只不過冇人睬佢，當佢傻佬咁樣! 我亦都同人哋講呢個才是真正解決問題嘅方案，啲人亦都當我係一個傻佬! 所以現今社會，當傳媒力量大於一切嘅時候，真正有知識嘅人講真話係不會被尊重的 😄
金錢問題,唔想TOYOTA獨佔技術,EV跟本一D都唔環保,因為要推電車呢門大生意全世界要有共識,全國想壯大一門新產業先會話EV環保
我撐你！眾人皆醉你獨醒！TOYOTA 除咗投資 Fuel Cell Electric Vehicle，最近仲同 YAMAHA 共同開發氫燃料引擎，Btw, 你個“氫”字寫錯咗。
那要先解决氢的储藏问题，作为机械工程师“氢脆”这个问题不会不知道吧？目前氢能源储藏都是用特别的罐子，一个罐子3500USD只能装30USD不到的氢气。而且目前96%的氢能也是从化石能源转化来的，和你吐槽的电能其实是一样的。但是提高发电厂效率的技术和速度远远超过私家车内燃机的，长远来看还有太阳能、水能和风能的补充，所以用电远远比直接烧油要环保的多。而氢能不解决根本的生产、储存和运输的基本问题，很难普及。
你知道嗎？電車在19世紀，已經生產應用了。但那時電池不能再充電，是用完即棄的。所以，才會被油車代替。現在科技可以做到，電池再充電。如今，只是舊瓶新酒而已。☹️但是，電車仍然有其缺點存在，在溫度低及山多地區，用家是非常心累的！真希望Nicola Telus的免費能源方程式，沒有被美國政府充公！何時人類才會沒有私心存在？
你有一个数据错了，电车的电机效率一般在70%到97%之间，平均为87%。各个电机厂商都有相应数据，可以自行查阅。
用氫氣代替引擎發電，充電電池，電池推動馬達，這樣方法電池會細好多，氫氣是環保，會比現在的EV好好多
造hydrogen仲污染過油車
氫氣用電解取得，電可以用水力或核電比較環保，主要針對減少CO2影響大氣層
@@ccc9847 現今主要由natural gas造hydrogen
@@ccc9847 如果用renewable energy做電咁電車計哂電池嘅waste都係一定好過hydrogen，以現今技術計
電車跟油車一樣，不是甚麼高科技, 個人認為未來十年后，那些品牌會跑出：平價的是大陸車（夠平），中價是丰田（夠reliable)，高中價是寶馬(夠handling)。

呢集好好，了解到成個環保產業鏈
真好嘢! Joule 通常譯焦耳，譯作蕉兒也可以，是能量单位，一「牛顿」Newton的力移动一公尺Meter所须能量為一Joule 或一蕉兒。也可演譯為吃一蕉兒可把一牛頓力移一公尺，太好了，容易明白。
好似講到改變下政策就可以令到童工同埋廢料問題好易解決，但係講到尾其實都係錢。要改變呢啲問題嘅話材料價格同埋廢棄處理價格都會貴好多倍，到時電動車就唔會係而家呢個價錢
還有污染物集中由發電廠處理還是汽車排放在街嘅分別
遲左睇！TAHNKS RAIN BB😊
最大瓶頸點都係電池生產，但係龍頭ALB股價大上大落，很難長坐。亦搞到次選的一籃子ETF based 的LIT唔上唔落。。。而且TSLA已見了頂又太過個人因素，好難捉摸。
多謝！
喜歡聽到由美女講述硬核科技知識！❤️❤️😉
謝謝你的支持！😉
最大分別係能源運輸問題，化石燃料重開採，提煉，儲存到賣比我地都要用到大量運輸，每日有大量運油輪係海上行駛，陸路又有運油車運去各油站，電就沒有呢D問題，發電廠只用電纜輸送到各區變壓站就可，當然發電廠在使用化石燃料時仍會有廢氣排放和運輸問題，但好處可習中處理，如果你今日重係坐緊柴油火車你會唔會覺得好怪，其實每樣嘢都有利有弊，兩害相較取其輕。

其實最好的能源是水，氫氣可燃，氧氣助燃，燃燒後變成水再循環使用，生生不息，又不會造成環境污染，只不過以現在的科技而言還沒辦法用一個裝在車裡面的儀器來生產。

正常嘅人類 工廠，生產， 生活上 碳排放係唔會導致溫室加劇， 地球本來就係一個超大型生態循環系統， 擁有自我調節能力； 真正 加速全球暖化和氣侯失衡嘅兇手 係軍事演習和軍事武器所釋放的能量， 呢啲數據就連大多數國家 基於安全 都唔會公佈 ， 如果環保組織知道真相就等同摧毀宗教人士的信仰。
唔係講政治，剛果人權問題無乜人會理，相信你唔講都無乜人會知，多謝你提醒左我地。 首先，我想講下買電動車，唔係淨係為節省能源成本，仲可以防止比出邊啲PK車房整到部跑車都變跛腳車，車房唔黑心邊會搵到錢，電動車好少野壞，有壞都會返廠整，唔會比車房佬襟住搶。揸過汽油車都知我講咩，BTW我諗香港啲車主，包括我，大部份都唔會因為想為地球環保出分力而買電動車~

將汽車排放廢氣變成電力廠排放廢氣或核能廢料,電力在輸送過程中是會有損耗的到用家使用時已不是100%

其實不算是電動車廠的醜聞，因為電動車近幾年普及之前用cobalt最多的是煉油廠和手機電池廠。近一年EV電池都逐漸減少甚至消除對cobalt的依賴，例如Ultium, NCM811和LFP等等。而且電池壽命已經可以比車架更長壽，甚至可以有100年的電池壽命，近一兩年的EV WTW已經上升到30－40%，是汽油車的2－3倍。加上已經有能夠回收95%物料的recycle 技術，EV只會繼續取代石化燃料汽車，而大車廠都深知這一點。

點解再生能源發電效能會高過煤??如果係咁地球應該一早用曬再生能源啦??轉化率高唔代表符合成本效益，而且有些轉化率低是物料是先天限制，轉化率低又唔代表排放一定最差!!同埋某類型發電排放管理技術可能特別好???就我所知發電廠發電效率和排放會比汽車引擎好，汽車行駛會有很多因素影響燃燒和排放，因為汽車引擎使用狀況唔係針對發電，功率會一直變化，燃燒過程要溫度和氧氣控制唔好就會加劇排放，燃燒得好就會產生H2O。例如﹕氣缸積碳嚴重令燃燒溫度上升，或渦輪增壓令缸內壓力過大，都會影響化學元素轉換。而且一般汽車排放，只有一個三元催化，同樣用貴金屬造，催化能力有限。汽車引擎是很難跟有規模發電廠比!!!
Good job 多謝靚女分析真係好多人都唔知道ev嘅黑暗污糟邋遢人係自私自利嘅動物💩👎😡🤔

目前是不打算买EV。 感觉上 EV目前的技术还没有成熟。例如： 燃烧问题， EV本身的辐射问题＆EV发出的低频问题等
事實上，能量每次轉換都會消耗一定的比率，故此，真係同一條蕉，直接推一駕車係比EV車更有效率，故此，EV車係低效一點。
只有暫時價錢較平，但講效能就…電要經好多電纜，電能的損耗率大，不過只係平就已經好多人鐘意。其實香港2大電廠的碳排放就佔全港碳排放的60-70%，車就18-20%其他係7-10%。用眼不見為淨的計算方法去講環保係無聊。 EV車暫時只係平。
@@HalloAnn 特別係香港，電費平（好快就加價）係因為燒煤同用核能（這點如用第4代就安全好多），這是環保支持者想要的嗎？
真正要做到環保，就要由源頭發電有一個永續，供電穩定，成本真正平宜的發電方法，所有太陽能，水力風力發電都係不切實際的，因不穩定就冇人用冇人投資以，要有比鋰電池更環保，儲電量更高更快的能量儲存裝置。
最後一點，環保人仕必須要知道，你買電車，舊果部汽車要點處理？賣出好報廢好，新車的建造也是，都要耗用勁多能源資源，眼不見為淨只是自欺欺人，實質是以環保為名，消費為實已。

爆光了？定係我個mon？
太陽能或風能因是renewable energy，efficiency考慮可能不同。要考慮發電工具的污染。
如果估計ev平均環保effect，就可以用全球現在電力生產方法 + 未來10/20年的變化考慮。
還有要考慮ev車意外問題。過去資料，ev車起火時滅火要用的水可以多過gas car好多。數字上ev的意外起火比例很低，但在ev相對gas car比例還低，未知多了後會否改變。
世界乾淨水資源缺乏，電池從生產，起火，回收時也要用大量的水。

謝謝分享!thx!!😊😊😊

EV 從來唔乾淨，只係將污染轉移，而且新舊產業鍊既對決而已。
EV 產業既人士，用盡一切左膠思想去打擊舊有產業，而自己都一樣滿手鮮血，然後新興既國家搵發達國家既政客去盲目推電車同埋其他發電既 project，更鐘意係襯而加有咁既潮流下一口氣打擊舊有既汽車行業，結果就係而加歐洲同英國咁既能源問題屎樣，兩個字形容：白癡
所有野發展都需要一步步黎，電車唔係唔好，但就連德國自己又要玩電又唔夠發電量去支撐，而且更要去依賴俄羅斯天然氣發電而放棄核電，2018 年比 trump 丙之後 2022 俄羅斯發動戰爭咪證明佢地呢班友幾咁短視又盲推所謂綠色能源囉
另外，你唔燒油唔開礦，都大把發展中國家去開去採，佢地更加唔同已發展國家有晒極為嚴格既監管同排放指標控制污染，而無一個所謂環保鬥士去嘈佢地，只會搵已發展國家既中產開刀，令人高度懷疑係點去 target 個社會階層做內部破壞啫

EV seems to be another marketing strategy to have consumers jump on new products. I have once checked that an EV, due to the weight of the battery, on average weighs up to 3 times more than a conventional fossil fuel car, so in terms of energy efficiency, you can do the maths. a Hybrid in fact makes more sense.
you can check all the extra work they do with cobalt mining for batteries that don't last very long. Moreover, electricity is still generated mostly by coal or petro. So the extra battery only means more mining and destroyed fields.

針永遠都無兩頭利㗎啦…自己國家都咪搞掂，總話干涉人哋國家排隊都咪到我哋啲小小市民啦…講環保根本就係廢話，環保咪即係返返石器時代
