比特幣挖礦轉向再生能源：邁向永續發展的積極一步

批評者長期以來一直指出比特幣挖礦對環境的影響，理由是高能源消耗和碳足跡。然而，潮流正在轉變； Woocharts 最近的報告顯示，比特幣挖礦所使用的能源中約 56.76% 來自再生能源。

Bitcoin mining has come under scrutiny for its environmental impact, with critics highlighting the high energy consumption and carbon footprint. However, recent reports indicate a shift toward sustainable practices within the industry.

比特幣挖礦因其對環境的影響而受到密切關注，批評者強調其高能源消耗和碳足跡。然而，最近的報告表明行業內正在轉向可持續實踐。

According to data from Woocharts, an estimated 56.76% of the energy used in Bitcoin mining is now derived from renewable sources. This marks a significant departure from the past, when fossil fuels dominated the energy mix for cryptocurrency mining.

根據 Woocharts 的數據，目前比特幣挖礦所使用的能源中估計有 56.76% 來自再生能源。這標誌著與過去的重大背離，當時化石燃料在加密貨幣挖礦的能源結構中占主導地位。

Historically, Bitcoin mining was heavily reliant on fossil fuels, which contributed to negative perceptions of its sustainability. However, technological advancements and the decreasing costs of renewable energy have provided incentives for miners to adopt greener practices.

從歷史上看，比特幣挖礦嚴重依賴化石燃料，這導致人們對其永續性產生負面看法。然而，技術進步和再生能源成本的下降激勵礦工採取更環保的做法。

Bitcoin miners have made progress in utilizing cleaner energy sources, with regions such as Quebec, Iceland, and Texas emerging as leaders in this effort. While Bitcoin mining still generates substantial carbon emissions (69 million metric tons annually), there has been an increase in the utilization of renewable energy sources, including hydropower (23%), wind (5%), and geothermal power. Notably, coal still accounts for 22% of the energy usage.

比特幣礦工在利用清潔能源方面取得了進展，魁北克、冰島和德克薩斯等地區在這方面成為了領先者。雖然比特幣挖礦仍產生大量碳排放（每年 6,900 萬噸），但再生能源的利用增加，包括水力發電（23%）、風能（5%）和地熱能。值得注意的是，煤炭仍佔能源使用量的22%。

The data from Woocharts suggests that this trend has been consistent since at least April 2021, contributing positively to the industry's image.

Woocharts 的數據表明，這一趨勢至少自 2021 年 4 月以來一直保持不變，為行業形像做出了積極貢獻。

Tesla and the prospect of Bitcoin payments

特斯拉和比特幣支付的前景

In February 2021, Tesla announced that it had purchased $1.5 billion worth of Bitcoin. The company stated that this move was intended to gain more flexibility to diversify and maximize returns on cash. At the same time, Tesla revealed its plans to accept Bitcoin as payment for its products.

2021年2月，特斯拉宣布購買了價值15億美元的比特幣。該公司表示，此舉旨在獲得更大的靈活性，實現多元化並最大化現金回報。同時，特斯拉透露計劃接受比特幣作為其產品的支付方式。

However, in May, Elon Musk took to X to announce that Tesla had suspended vehicle purchases using Bitcoin due to concerns over the rapidly increasing use of fossil fuels for Bitcoin mining. Later, Musk stated in an X post that if Bitcoin reaches around 50% clean energy usage, Tesla would consider reinstating its Bitcoin payment option. Given the recent progress on sustainable energy usage in Bitcoin mining, the current figure provided by Woocharts may lead to renewed discussions on re-accepting Bitcoin as a payment method for Tesla products.

然而，今年 5 月，馬斯克 (Elon Musk) 在 X 上宣布，由於擔心比特幣開採中化石燃料的使用迅速增加，特斯拉已暫停使用比特幣購買車輛。隨後，馬斯克在 X 貼文中表示，如果比特幣達到 50% 左右的清潔能源使用率，特斯拉將考慮恢復其比特幣支付選項。鑑於比特幣挖礦中可持續能源使用的最新進展，Woocharts 提供的當前數據可能會引發關於重新接受比特幣作為特斯拉產品支付方式的新討論。

One noteworthy example of sustainable mining practices is Ethiopia's utilization of hydropower from the Renaissance Dam to bolster its Bitcoin mining industry. In 2022, this initiative generated $1 billion in revenue, which constituted 18% of the country's electricity income. By transforming surplus hydropower into a valuable asset, Ethiopia is attracting global investors and fostering economic growth, showcasing how sustainable energy can serve as a catalyst for progress in Africa's cryptocurrency landscape.

永續採礦實踐的一個值得注意的例子是埃塞俄比亞利用復興大壩的水力發電來支持其比特幣採礦業。 2022年，這項措施創造了10億美元的收入，佔該國電力收入的18%。透過將過剩的水力發電轉化為寶貴的資產，埃塞俄比亞正在吸引全球投資者並促進經濟成長，展示永續能源如何成為非洲加密貨幣領域進步的催化劑。

As Donald Trump's victory in the U.S. presidential election continues to drive up the price of Bitcoin, the cryptocurrency was last seen trading at around $93,409. If Tesla decides to accept Bitcoin for payments, it could provide a substantial boost to the cryptocurrency's price as we approach 2025.

隨著唐納德·川普在美國總統大選中的勝利繼續推高比特幣的價格，該加密貨幣最後一次交易價格約為 93,409 美元。如果特斯拉決定接受比特幣支付，那麼隨著 2025 年的臨近，加密貨幣的價格可能會大幅上漲。

Moreover, the U.S. reserve serves as a fundamental catalyst for Bitcoin's price growth. Bitwise's conservative estimate suggests that Bitcoin might hit $200,000 by the end of 2025, while VanEck anticipates a maximum price of $180,000.

此外，美國儲備是比特幣價格上漲的基本催化劑。 Bitwise 的保守估計表明，到 2025 年底，比特幣可能會達到 20 萬美元，而 VanEck 預計最高價格為 18 萬美元。
