Environmental Initiatives: Ethereum 2.0 aims to reduce energy consumption through its transition to a proof-of-stake consensus mechanism.

Reduced Energy Consumption:

Elimination of Mining: PoS eliminates the need for energy-intensive mining operations required in PoW, significantly reducing the overall energy consumption of the network.
Energy Efficiency: Validators in PoS consume much less energy compared to miners in PoW, as they do not need to solve complex mathematical problems to validate transactions.
