How much energy does Bitcoin consume?

Is bitcoin mining affecting the global energy crisis based on fossil fuels today?
In this post, we will answer some of the key questions you might have about Bitcoin’s energy consumption. But first, we need to understand why Bitcoin consumes energy.
🔸 Why does Bitcoin consume energy?
The Bitcoin network has its own evidence-based consensus-proof (POW) mechanism that requires Bitcoin miners to solve complex mathematical puzzles to add more Bitcoin to the circulation.
On the other hand, validators verify the authenticity of all Bitcoin transactions. All Bitcoin network processes, including Bitcoin mining and transaction verification, require significant CPU and GPU resources. However, there is a significant difference between these two processes in terms of energy consumption.
Checking Bitcoin transactions is not as energy intensive as Bitcoin mining. Once Bitcoin is mined, energy requirements progress drastically. Bitcoin miners and transaction validators are rewarded for Bitcoin mining, ie for confirming transactions. Therefore, the popularity of Bitcoin continues to increase over a period of time, which naturally causes an increase in energy consumption.
