1/ Bitcoin critics continue to assert that mining is wasteful and disproportionately damaging to the environment. 

Contrary to consensus thinking, we believe the impact of bitcoin mining is a net positive for the environment.

比特幣批評者持續宣稱採礦是浪費能源並對環境造成遠大於收益的破壞。

與這種思維相反，我們相信比特幣採礦對環境的影響是純正向的。

Here's why:

原因如下

2 /首先，工作量證明挖礦對比特幣至關重要。在比特幣網絡中，可信度受到計算的保護，而挖礦使比特幣具有協調信任和促進價值轉移的能力，而無需依賴集中的權限。

3 /生產比特幣的成本高昂是其價值的基礎。

與美元不同，比特幣不能用鍵盤按鍵來打印。

相反，它將廉價的滯留能源的輸出轉換為具有貨幣價值的東西。

4/ Even so, Bitcoin’s energy consumption is trivial compared to legacy financial systems. As measured by electricity costs alone, Bitcoin is much more efficient than traditional banking and gold mining on a global scale.

4 /即使這樣，與傳統金融系統相比，比特幣的能源消耗卻微不足道。僅用電費來衡量，在全球範圍內，比特幣的效率要比傳統銀行和金礦開採高得多。

5/ Traditional banking consumes 2.34 B GJ/yr and gold mining 500 M GJ/yr, while Bitcoin consumes 184 M GJ/yr.

Additionally, Bitcoin mining’s estimated $ cost / GJ expended is 40x more efficient than that of traditional banking and 10x more efficient than that of gold mining.

5 /傳統銀行每年消耗2.34 B GJ，黃金開採每年500 M GJ，而比特幣每年消耗184 M GJ。

此外，比特幣採礦估計的每GJ成本，比傳統銀行業務有效率40倍以上，比黃金采礦有效率10倍以上。

6/ Another common mistake energy detractors make is to naively extrapolate Bitcoin’s energy consumption to the equivalent CO2 emissions. What matters is the type of energy source being used to generate electricity.

6 /能源誹謗者犯的另一個常見錯誤是，天真的將比特幣的能源消耗推斷為等效的二氧化碳排放量。重要的是用於發電的能源類型。

7/ In reality, renewables account for the largest percentage of bitcoin’s energy mix. In the search for the cheapest form of electricity, miners flock to regions offering a glut of renewable electricity, unlocking stranded energy assets.

7 /實際上，可再生能源在比特幣能源結構中所佔比例最大。在尋找最廉價的電力形式時，礦工們湧向提供大量可再生電力的地區，從而釋放了處於困境的能源資產。

8/ In some instances, Bitcoin mining is even helping to reduce greenhouse gas emissions by consuming methane that would have been leaked into the atmosphere via flaring.

8 /在某些情況下，比特幣開採會通過消耗甲烷，避免去燃燒洩漏到大氣中的甲烷，這樣甚至有助於減少溫室氣體排放。

9/ "That energy would have been wasted, as is evidenced by the existence of flare stacks. That gas is flared because it can't be brought to market. Bitcoin miners are incentivized to show up and consume that wasted energy."

- @martybent

9 /“這種能源本來就被浪費掉了，正如火炬煙囪的存在所證明的那樣。這種天然氣被點燃是因為無法將其推向市場。激勵比特幣礦工出現並消耗掉這種浪費的能源。”

10/ "If Bitcoin ends up being worth substantially more in the future Bitcoin’s energy expenditure may end up looking rather cheap in the final analysis." - @nic__carter

10 /“如果最終比特幣最終價值更高，那麼最終分析中比特幣的能源支出可能看起來相當便宜。” 

11/ Coins only need to be issued once. And it’s better for the planet that they be issued when the coin price was low, and the electricity expended to extract them was commensurately low.

11 /硬幣只需要發行一次。而且對於地球來說，最好在硬幣價格低時發行它們，並且提取它們所消耗的電力也就相應地低。

12/ In summary, Bitcoin does not waste energy.

It is clear that because Bitcoin’s footprint is so easy to quantify, it is singled out for special treatment.

12 /總之，比特幣不會浪費能源。

顯然，由於比特幣的足跡很容易量化，因此它被特別選中。

A significant portion of bitcoin’s energy consumption is generated from renewable resources.

Bitcoin will spur innovation in the development of renewable energy technology & resources.

Bitcoin consumes energy that is otherwise wasted, if not, flared into the atmosphere.

Bitcoin consumes only the energy that the free market will bear at a free market rate.

Bitcoin consumes energy resources that would otherwise not be economic to develop.

The nature of bitcoin energy demand will improve the efficiency of energy grids.

比特币很大一部分能源消耗来自可再生资源。

比特币将刺激可再生能源技术和资源开发的创新。

比特币消耗的能源，大都是沒有太多開發價值。如果不利用，就会浪费到大气中。

比特币只消耗自由市场以自由市场速度承受的能量。

比特币消耗的能源，大多是开发起来不经济的。

比特币能源需求的本质将提高能源网的效率。
