電動車其實更不環保？美國研究認為必須減少對電動車的依賴

近年來或許是受到全球暖化及空氣污染議題的影響，行駛過程中0排放的電動車，就成為了未來汽車發展的主流方向，並得到各國政府大力的支持與推動；然而，近期一份美國研究發現，電動車不僅沒有更環保，還可能對地球生態造成更多負面影響。
美國加州大學的一項研究指出電動車帶來的嚴重問題
根據近期一份來自美國加州大學的一項研究發現，電動車中最重要的配置之一-鋰電池，其中的鋰礦開採將對環境造成危險與不可逆的破壞，其危害程度相當之大；而電動車的迅速發展，也加速了鋰礦的開發，不僅可能造成嚴重的乾旱危機，更會讓礦場周圍的生物多樣性減少或消失。
因電動車發展大量生產的鋰電池可能是地球污染的一大元凶
且該研究指出美國的例子，該國已知的鋰礦礦區中有79%，位於原住民保留區的56公里內，而採礦作業卻往往未獲得當地居民的支持及認同，衍生許多複雜的社會與環境問題，而同樣關於採礦的問題，也同樣發生於智利、阿根廷等等富有礦產資源的南美洲國家；此外鋰礦的開採要消耗大量的水源，對於現今許多地區日益嚴重的乾旱與荒漠化問題無疑是雪上加霜。
鋰礦開採對生態造成巨大破壞
最後，還是回歸到鋰電池最大的隱憂－廢棄電池回收的議題，目前各國政府或企業仍然對其沒有一定共識，筆者認為，在許多不可控因素尚未被確定前，貿然的大規模推行電動車可以說是相當危險的選擇；現今適逢台灣礦業法的修訂三讀通過，我想關於鋰電池的議題也變得更值得探討。

鋰電池係最大問題, 不過只要解決呢個問題, 電動車係會環保d, 好似馬斯克定邊個話遲d唔會用鋰做電池?
Its time to put TSLA
Hydrogen fuel 
用油最好
你估太陽能板好環保
水力連周邊生態系統都破壞埋

唔用電回歸原始社會就最環保
US STUDY FINDS ELECTRIC VEHICLE RELIANCE MUST BE REDUCED

A study from the University of California has found that lithium mining presents an environmental danger, and that electric vehicle size must be reduced.

A study in the US has found that the lithium that is used in the batteries of an electric vehicle, could be leading to environmental destruction.
The primary factors in the conclusion of the study, which was conducted by the University of California, regard the mining operations used to harvest lithium.

“Large-scale mining entails social and environmental harm,” the study says, which can include an increase in drought intensity and reductions in biodiversity.
The study found that “In the United States specifically, 79 percent of known lithium deposits sit within 35 miles of Native American reservations,” and that mining operations are often begun without obtaining the permission of the indigenous people in the area.
There are, therefore, both environmental and social issues regarding mining, the second of which the study says are also apparent outside the US, in South American countries such as Chile and Argentina.
Additionally, as global warming increases, the Earth's water shortage intensifies. Europe is not typically in drought, historically speaking, but even places like the UK were in drought conditions in 2022, and already this year much of France is warned of drought conditions. One US-based example of a proposed lithium mining project would have an equivalent annual water usage of 15,000 US homes. So, it is clear to see that lithium mining actually exacerbates issues (or, at least, an issue) created by global heating, which the lithium itself is intended to ease.
The impact of this on the transport industry is significant, since, despite the use of lithium in batteries for a large number of applications including standard household electronics, the largest demand for lithium comes from the transport industry, as reported by the Guardian.

porsche都搞緊e-fuel, 完全零排放, 根本鋰仲毒, 係啲政府on9 ban汽油車
廢氣一定程度可以經大自然回復 ，但電池入面D 重金屬乜乜物料唔用埋落地下 就乜都唔洗種。
採油咪一樣唔環保
轉用鹼性電池咪得囉
少少野都諗唔到

要計要由探測原材料開始， 每一個step, 採礦，抽取，合成，到最後造件產品出黎咁計囉
計其中一環無意義

特斯拉於加拿大達爾豪西大學（Dalhousie University）的「先進電池研究小組」近日發布最新研究成果，國際知名的電池專家傑夫．達恩（Jeff Dahn）發明了新型鎳電池，使用壽命可高至一百年，能量密度比傳統的鋰離子電池更高，因此亦比鋰離子電池更小型，節省更多空間。現時特斯拉電動車所使用的鋰離子電池由日本的松下電器（Parasonic）提供，有兩大主要缺點，第一是國際鋰礦存量不足，第二是鋰電池壽命不長，並且在廢棄的時候會對環境造成龐大污染。
班石油公司仲有咩新論點呀？

用電去左發電廠生產， 發電廠有燒煤or 油，電車無環保到， 仲要做多左D電池出黎， 內燃機就直接燒油但電廠用電小左無須發咁多電 計落仲小左生產電池。
