eTukTuk (TUK) – Energy-Efficient Crypto Powering Up Tuk Tuks Using Sustainable Energy

With over 270 million Tuk Tuks available across the globe, the internal combustion engine they use is wreaking havoc across the environment. Cost factors, too, are a major concern as there has been over a 50% increase in fuel costs in many countries. The answer to this issue lies in the adoption of a greener approach that electric-powered Tuk Tuks the norm. Making that a reality is an energy-efficient crypto project known as eTukTuk.

eTukTuk is the world’s first automotive project. Built on the Cardano blockchain, eTukTuk aims to make EV solutions accessible throughout the world, starting from Sri Lanka.

eTukTuk energy efficient token

While electric-powered vehicles have increased in number for those, who use them privately, we can’t say the same for public transportation.

Lack of awareness and the lack of cost-efficient models are a couple of contributors to that issue. With eTukTuk, however, this problem is set to be solved using blockchain technology. The project aims to promote both EVSE (Electric Vehicle Supply Equipment) and Zero Emissions Vehicles. And to make them a norm, eTukTuk plans to engage in a “territorial partnership” with certain regions. Territory partners will collaborate with eTukTuk to install and operate essential services for operating, maintaining, and delivering eTukTuks.

This project is fruitful for both individuals and institutions. eTukTuk is inviting public and private sector entities to become partners to expand this project. However, the major key drivers of this project will be the drivers and the passengers for whom eTukTuk is developing an app.

eTukTuk is powered by the TUK token. TUK has a supply of 2 billion and follows a controlled, reduced inflationary mechanic. Upon the launch of the network, a controlled, reduced inflation rate will be put in place, and the token will be distributed to TUK stakers over a span of 15 years.

Ethereum (ETH) – Leading Energy Efficient Cryptocurrency in 2023

Ethereum is the world’s second-largest crypto project and needs no introduction. But what you need to know about ETH is its latest transition to energy efficiency. ETH is moving away from its energy-intensive proof-of-work (PoW) mechanism to the proof-of-stake (PoS) – a move aimed at aligning its underlying technology with sustainability principles.

This transition from PoW to PoS, called “The Merge” will reportedly lead to a drop in energy use by an overwhelming 99.95%. The Merge is taking place in two phases, the first beginning on September 6, and the second between September 10 and 20.

The Ethereum Merge is aimed at getting rid of the high-energy-consuming mining process so long used to validate ETH transactions. This eliminates the need for energy-intensive mining equipment, thus reducing Ethereum’s contribution to CO2 emissions.

Furthermore, by switching to energy efficient crypto, validators will be able to validate transactions using ordinary devices such as laptops and PCs. As a result, Ethereum is expected to be one of the best proof-of-stake coins in the long run.

Hedera (HBAR) – Best Crypto Alternative to Blockchain in Terms of Energy Efficiency

Hedera Hashgraph has been deemed as the cryptocurrency that can compete with the biggest payment processors in terms of the number of transactions per second.

But that is not its biggest USP. It can process substantially voluminous transactions faster while using far less energy compared to projects like Bitcoin. Besides, HBAR’s instant transaction speeds allow the project to be used for almost any practical applications that require real-time responses.

BUy Hedera Hashgraph

The reason behind HBAR’s strong capabilities is its unique framework which handles transactions in parallel instead of linearly. It employs its own consensus mechanism called virtual voting, as opposed to the common Proof of Work (PoW). Virtual voting sets itself apart with zero energy loss in the coin minting process.

While still providing a publicly available ledger, HBAR functions using “hash graphs” instead of “blocks” to authenticate transactions. This hash graph consensus is unique to Hedera, and is “a faster, more secure alternative to blockchain consensus mechanisms,” according to its website.

With its novel chatter about gossip protocol and virtual voting, Hashgraph enables high throughput with 10,000+ transactions per second today and low-latency finality in seconds. Once consensus is obtained, the transaction is immutable and visible to everyone on the public ledger.

Powerledger (POWR) – Solana-Based Energy Efficient Cryptocurrency

Powerledger is one of the few crypto projects to have a female co-founder. It was initially established in 2016-17 as an Ethereum token but has switched to the less energy-intensive Solana in 2021 to keep up with its aim of energy efficient transaction throughput.

The reason behind this transition was to take advantage of the scalability of the Solana code base, which Ethereum had still not introduced until then.

The peer-to-peer Powerledger operating system tracks the trade of energy, flexibility services, and environmental commodities on an underlying vision of the decentralized grid. When energy inputs and outputs are inconsistent, such as is the case with renewable energy like solar and wind, a centralized power grid becomes increasingly problematic.

buy powerledger

Powerledger offers a distributed, decentralized network that enables producers to track, trace, and exchange energy in real-time, resulting in more stable and robust energy networks. Blockchain technology and POWR token in particular are critical pillars for this vision.

The customized permissioned Solana blockchain of the platform employs Proof-of-History and Proof-of-Stake (PoS) consensus methods which allow even vast transaction volumes to be faster and less energy-intensive compared to existing PoW blockchains.

Powerledger also incorporated Safecoin’s voter subset consensus to limit the number of administrative type transactions handled by the blockchain. This is helping maintain the network as more secure and energy efficient than ever before.

Ripple (XRP) – Crypto with the Lowest Energy Consumption in the Decentralized Payments Niche

Ripple is the “first blockchain company to pledge to be carbon-zero by 2030”, and is making the big shift to renewable energy sources for this vision.

The permissionless, decentralized cryptocurrency Ripple shuns the energy-intensive Proof-of-Work consensus for its own “distributed agreement” mechanism, which necessitates agreement from a supermajority of nodes to validate transactions.

Put simply, the process demands that most validators must approve a transaction before it can be added to a ledger. Ripple’s native digital asset XRP does not require mining, lowering the carbon footprint of technologies built on the Ledger even further.

Server company TRG Datacenters reported in April that XRP was the least energy intensive of the seven major coins it examined (the others being Dogecoin, Cardano, Litecoin, Bitcoin Cash, Ethereum and Bitcoin). It uses 0.0079 kWh of electricity each transaction, which is only 0.00112% of the 707-kWh used by Bitcoin.

Ripple also has a separate ‘Carbon calculator’ on its website that displays the network’s energy consumption relative to Bitcoin and Ethereum, highlighting that it is one of the most energy-efficient cryptos. For example, ETH uses 2.57 billion kWh of energy per year, whereas Ripple uses only 474,000.

Nano (NANO) – Free Energy Efficient Cryptocurrency with Latticed Network

Nano calls itself “a digital currency for everyone, without fees.” The crypto project consumes much less energy compared to Bitcoin and several other leading cryptocurrencies since it does not rely on mining at all.

Unlike other cryptocurrencies, there is no record of any chain of transactions on Nano. Instead, Nano works on an underlying technology of energy efficient block lattice. All accounts on Nano form a lattice of interconnected blocks, and every user gets more control over their own account.

buy nano today energy efficient

The accounts are updated asynchronously, rather than requiring the use of a complete linear blockchain, as is the case with Bitcoin and others. This independence from a chain of competing transactions enables Nano to establish a sender-receiver account chain for each network user separately.

The result? Nano allows for up to 125 transactions per second, is scalable and lightweight, and despite still using a Proof of Work mechanism, it works at a minimal carbon footprint.

There are other characteristics that set the platform apart. Nano is free, which means you can send tokens at zero cost. This makes the platform accessible and inclusive for all. Nano also does not rely on either mining or printing or minting and allows instant digital currency payments.

SolarCoin (SLR) – Providing Incentives-Based Boost to Renewable Energy Production

SolarCoin is a unique crypto project that incentivizes users for producing solar energy, thus bringing renewable energy and energy efficiency into the limelight. The global, decentralized cryptocurrency issues one SLR for every Megawatt hour of solar energy produced by the user.

As per its website, “SolarCoin is an alternative digital currency that works like air-miles for Solar electricity generation.” In this way, the token is rewarding its community for lowering the cost of electricity production.

solarcoin energy efficient incentive

Introduced in 2014, the network relies primarily on people submitting paperwork to confirm energy generation, but the Internet of Things may one day automate this process with automatic updates from solar arrays.

The one-of-its-kind platform is helping conserve natural capital while sustaining an incentives scheme at the same time, tying in energy efficiency with financial gains for users. The asset also intends to provide extra incentives to solar energy producers.

Chia (XCH) – Leveraging Space and Bandwidth for Customized Throughput

Chia is mined using the Amazon Web Services (AWS) cloud computing technology. The project offers a more sustainable, lighter, and simpler “farming” mechanism as opposed to “mining” of other currencies.

It was founded in response to the excessive energy consumption associated with crypto mining activities and uses no specialized equipment or vast amounts of power for its farming process. Chia leverages your computer’s hard disk space and uploads bandwidth instead of energy-intensive computation. It eliminates extraneous data from blocks and only validates them as needed.

chia energy efficient crypto

Its consensus algorithm is freely available to the public as the Mainnet blockchain transaction platform and is downloadable at

After installing the software, you can opt to donate a portion of your uncommitted hard drive space to the network without severely hurting its speed or consuming significantly more energy. This is enabled by Proofs of Replication (PoRep) which incentivizes users to share hard disk space for network security in exchange for XCH rewards.

Established by the inventor of BitTorrent, Chia enables smart transactions using Proof-of-Space Time instead of Proof-of-Work. The parameters of space and time are adjustable as per your system’s bandwidth and storage, enabling a distributed consensus geared for efficiency and sustainability.

IOTA (MIOTA) – Digital Autonomy with the Promise of Eco-Friendliness

IOTA is a refreshing micro-transaction crypto project that has been designed with the Internet of Things (IoT) revolution in mind. It eliminates transaction fees and accepts even the smallest nano payments.

The platform largely employs the Fast Probabilistic Consensus and depends on the Proof of Work only partially to maintain reduced energy consumption overall.

It outperforms Bitcoin in this aspect and is only set to create new benchmarks in energy efficiency with its Atomic Transactions norm in the future, reducing transaction sizes from 1.7 KB to less than 100 bytes, which will lower energy consumption proportionately.

IOTA coin energy efficient investment

IOTA functions on the Tangle distributed ledger architecture that renders it free from blocks, chains, and hence mining. The platform describes itself as the future backbone of IoT, enabling tamper-proof data, micropayments with no transaction costs, and low resource requirements.

IOTA’s goal is to build a “machine economy” by enabling simple machine-to-machine transactions and connecting human and machine economies. Its innovative transaction validation model uses nodes to compare two previous transactions (called tips), reducing the amount of time and memory to validate transactions.
