Introduction

The network’s Proof-of-Work (PoW) consensus procedure has caused considerable energy requirements for Bitcoin, which have undoubtedly tarnished the cryptocurrency market’s reputation. Several cryptocurrency projects now strive to offer a more energy-efficient solution to draw investors who care about the efficient cryptocurrency options for the environment.

When searching for the cryptocurrency with the most potential, investors may wish to consider energy-efficient activities. This is because the most energy-efficient bitcoin projects regularly employ the most advanced technology, making them “futureproof.”

Environmentalists claim that certain technologies like Bitcoin are bad for the environment because they consume a lot of energy during their mining and are a totally not efficient cryptocurrency option. Fans of cryptocurrencies claim that the current financial system is not environmentally friendly. The amount of fossil fuels consumed by huge banks to power their infrastructure is staggering.

Is Hedera Hashgraph in efficient cryptocurrency options?

The decentralized public network Hedera Hashgraph, which is utilized for in-app purchases and micropayments, is one of the biggest cryptocurrency networks in the world. Its native, hashgraph-based, energy-efficient coin HBAR is used on its widely used public proof-of-stake network, which is notable for consuming very little bandwidth.

The Hedera Governing Council, composed of up to 39 organizations and businesses with term limits, including LG, Boeing, Google, and Deutsche Telekom, also serves as its governing body. Hedera Hashgraph and Power Transition, a peer-to-peer energy trading and microgrid management cloud-based software and hardware platform, have joined forces to create and develop sustainable projects and become one of the energy efficient cryptocurrency options.

As part of these initiatives, energy efficiency improvements will be made to homes and flats in the UK. Hedera Token Service will be used as the payment system at EV charging stations, which will result in a 50% reduction in charging costs. The Hedera Hashgraph platform requires only 0.001 kWh for each transaction, compared to 250 kWh for Bitcoin (Digiconomist estimates it needs 950 kWh), 55 kWh for Ethereum, and 0.003 for Visa, according to the eco-friendly website LeafScore to be among the efficient cryptocurrency options.

SolarCoin an efficient cryptocurrency option

2014 saw the launch of SolarCoin, a cryptocurrency that aims to be 50 times more carbon-efficient than bitcoin. The price at which one SolarCoin (SLR) is equivalent to the offer price for one-megawatt hour (MWh) of solar PV (photovoltaic) energy is known as “Solarity,” which they even coined.

Contrary to energy-hungry bitcoin mining, solar coins are awarded to participating owners of solar power systems depending on how much electricity they produce, not how much energy is required during mining. The SolarCoin Foundation, a worldwide initiative for solar energy awards with over 100 participant nations, gets data on energy production from the individual owners’ systems via a platform or monitoring system.

Each megawatt hour that generators produce is worth one penny. Making money and generating your electricity using solar power Or, to put it another way, their objective is “to accelerate solar energy absorption and the global energy transition to a low-carbon source of energy.” For the next 40 years, Solarcoin will serve as a free global incentive for solar energy. By rewarding generators with solar coins, we may promote the production of solar electricity and reduce the cost of power generation.

BitGreen

BitGreen is a cryptocurrency substitute that uses less energy and was established in 2017. A feature of BitGreen’s unique protocol is the low-energy Proof-of-Stake (PoS) method. By rewarding ecologically-friendly decisions, much like SolarCoin does, they can achieve their focus on sustainability.

Users are rewarded for actions that lower their carbon footprints, such as signing up for bike share programs, volunteering in the community, or making purchases from environmentally friendly businesses and organizations (s). Users can connect with partners to earn and spend BitGreen awards and look into greener solutions using BitGreen Mobile, a mobile-only wallet that also supports its native token.

The world is full of inspiring people working to heal our planet, combat injustice and global warming, and contribute to building a brighter future, claims BitGreen’s website. Even if only a small percentage of their lofty goals are realized, the world will be that much greener as a result.

Algorand

Algorand, the first proof-of-stake-only blockchain-based cryptocurrency network, was created in 2017 by MIT researcher and 2012 Turing Award recipient Silvio Micali. The test network was introduced in 2019. Although ALGO is the dominant cryptocurrency in the system, smart contract functionality is supported by the platform itself.

The lack of mining is a benefit for the ecosystem in Algorand. Their website claims that a network node can be run using only a little amount of electricity using a Raspberry Pi or other similarly simple devices. According to a preliminary study, Algorand emits almost 2 million times less CO2 during the generation and trading of digital assets than other blockchains.

ClimateTrade, a leader in CO2 emissions transparency and traceability, worked with the platform to create the most environmentally friendly blockchain with a carbon-negative network. Creating a sustainability oracle that notarizes Algorand’s carbon effect on-chain for each epoch, Algorand and ClimateTrade will be able to do this.

By securing the same number of carbon credits into a green treasury as an ASA using Algorand’s protocol’s cutting-edge smart contracts, the protocol will continue to be carbon-negative. By 2030, a total of 10 billion ALGO will be shipped.

Chia (XCH)

The Chia Network was established in 2017 by Bram Cohen, the man behind BitTorrent. Chia is a platform for smart contracts and blockchain that lets users use free hard drive space to maintain a decentralized network. Users can earn the Chia token, or XCH, on the Chia Network, which uses proof-of-space and time rather than proof-of-work like Bitcoin. It retains a particular amount of data over a certain length of time.

This alternative to cryptocurrency mining uses far less energy. Chinese coin miners hedged their bets before the cryptocurrency’s introduction in May 2021, which led to a hard drive shortage and price increases. Drive manufacturer Seagate had to alter their output to fulfil demand when shortages were also reported in Vietnam.
