With an energy consumption of just 0.0079 kWh per transaction.Algorand (ALGO)Algorand is a cryptocurrency that uses the Pure Proof-of-Stake (PPoS) consensus algorithm. It consumes significantly less energy than PoW and is more secure than PoS. Algorand’s blockchain is designed for high-performance applications such as decentralized finance (DeFi) and enterprise solutions. Algorand is dedicated to reducing its carbon footprint and therefore has taken the initiative to purchase carbon credits via smart contracts. By buying credits, not only does it cut its own emissions, it also invests in projects committed to fighting climate change, such as renewable energy initiatives.MetaHash (MHC)MetaHash is a cryptocurrency that uses a consensus algorithm that combines the PoS mechanism and a form of sharding called metachains. This allows for high throughput and scalability while maintaining energy efficiency.Powerledger (POWR)Powerledger (POWR) is a blockchain-enabled energy platform that allows for peer-to-peer trading of renewable energy. The project focuses on carbon credits and carbon neutrality. It uses smart contracts to track the production and transfer of energy from one node to another, letting households buy and sell renewable energy at lower rates than traditional energy companies.Hedera (HBAR)Hedera (HBAR) is a carbon-negative public distributed ledger technology platform. It offers fast, secure, and fair services for businesses of all sizes to use in their digital assets and applications.Using just 0.001 kWh per transaction, as opposed to 250 kWh for Bitcoin (Digiconomist estimates it to use 950 kWh), 55 kWh for Ethereum, and 0.003 kWh for Visa, the Hedera Hashgraph platform is 250,000 times more energy efficient than Bitcoin, according to the green website LeafScore. HBAR is considered the most energy-efficient crypto.SolarCoin (SLR)SolarCoin is a relatively new cryptocurrency that was created specifically to incentivize the adoption of solar power. The project rewards solar energy generation contributors with SolarCoins, which can be traded on cryptocurrency exchanges. Unlike many other cryptocurrencies, SolarCoin uses a proof-of-stake (PoS) consensus mechanism, which requires much less energy than PoW. This makes it one of the most energy-efficient cryptos available.BitGreen (BITG)BitGreen is another PoS-based cryptocurrency that aims to promote sustainable practices. The project encourages users to engage in environmentally-friendly activities like recycling and reducing their carbon footprint and rewards them with BitGreen coins. BitGreen also uses a unique “mint-and-burn” mechanism to control the supply of coins, which helps to lessen inflation and maintain price stability.How Does a Cryptocurrency Become Energy Efficient?A cryptocurrency can become energy efficient by using alternative consensus mechanisms that are more energy-efficient than traditional Proof of Work (PoW) mechanisms. For example, some cryptocurrencies use Proof of Stake (PoS) or Proof of Authority (PoA) mechanisms, which require much less computational power and energy to verify transactions and maintain the network.The Merge (previously known as Ethereum 2.0) reduced Ethereum’s network power
