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

Enhanced Scalability:

Sharding: Ethereum 2.0 introduces sharding, a technique that splits the blockchain into smaller, more manageable pieces, reducing the computational load and energy required to process transactions.
Layer 2 Solutions: Layer 2 scaling solutions, such as rollups, further reduce the energy consumption per transaction by offloading some of the computational work from the main Ethereum chain.
