Exploring the use of blockchain technology in the renewable energy sector and its potential to create a decentralized energy market

Blockchain Technology and its Impact on the Renewable Energy Sector

The renewable energy sector has been growing at a rapid pace, with a growing demand for clean and sustainable energy sources. However, the conventional energy market is centralized and controlled by a few large corporations, leading to a lack of transparency. Blockchain technology has the potential to transform the energy sector by creating a decentralized market, where consumers can generate, share, and trade energy directly with one another.

What is Blockchain Technology?

Blockchain is a decentralized, digital ledger that records transactions across a network of computers. It is the technology behind the popular cryptocurrency, Bitcoin, but its potential uses go far beyond just financial transactions. One of its key features is the ability to enable peer-to-peer transactions without the need for a central authority, making it a valuable tool for creating a decentralized energy market.

Decentralized Energy Market

A decentralized energy market would increase competition in the energy sector, as more players would be able to participate in the market. This would lead to a more efficient market, with lower costs for consumers. Additionally, a decentralized energy market would better integrate renewable energy sources as the distributed nature of renewable energy generation would align with a decentralized market. One of the key benefits is that it would allow for greater participation by individuals and communities in the energy sector, empowering communities to generate their own energy and sell the excess back to the grid. This would also increase energy security, as communities would not be dependent on a central authority for their energy needs.

Peer-to-Peer Energy Trading

One of the most significant potential uses of blockchain technology in the renewable energy sector is peer-to-peer energy trading. This would allow individuals and communities to trade energy directly with one another without the need for a central intermediary, increasing competition in the energy market and lowering costs for consumers. It would also allow for greater flexibility in the energy market, as energy could be traded in real-time, meeting the changing needs of the market. Blockchain technology would increase transparency in the energy market, as all transactions would be recorded on the blockchain, creating an auditable and immutable record, preventing fraud and increasing trust among market participants.

PowerLedger: A Decentralized Energy Trading Platform

PowerLedger is a blockchain platform that provides a solution for a decentralized energy market. It enables consumers to trade renewable energy directly with one another without the need for a central intermediary. The platform uses smart contracts to facilitate transactions and provides a transparent and secure record of all energy transactions. PowerLedger has already been implemented in a number of successful pilot projects and has been recognized for its potential to disrupt the traditional energy market.


The potential benefits of blockchain technology in the renewable energy sector are numerous. A decentralized energy market would increase competition, lower costs for consumers, and allow for greater participation by individuals and communities in the energy sector. Peer-to-peer energy trading, enabled by blockchain technology, would increase transparency, trust, and flexibility in the energy market. PowerLedger is a leading project in the decentralized energy market, using blockchain technology to trade excess renewable energy and create a transparent record of all energy trades. In conclusion, blockchain technology has the potential to create a more efficient, sustainable, and transparent energy market for the future.

Blockchain use explained with Google Docs

To explain how the blockchain use to the newbies it is easier to compare its functionality to Google Docs, the popular document tools I’m using to write this article.
“The Business of Blockchain” author, William Mougayar, in fact, said that the two tools have something in common and this comparison is very useful to explain the blockchain use.
Everyday you can find new use cases of the distributed ledger and the more people understand how it works, the more we will see an improvement in this revolutionary technology.
Who invented the blockchain didn’t probably imagine all of its possible applications, which is the reason why nowadays there are more and more experts with a deep knowledge in a particular side of the technology.
But, the first step is having a good expertise in the blockchain use.

Blockchain Use is similar to Google Docs

The blockchain is similar to a database, but the ledger doesn’t revolution databases themselves, but how they get synchronized, explained Mougayar in his article appeared on Coindesk.
If two banks need to update their own account balances, they need to spend a lot of time and energy to coordinate, synchronize and ensure that each transaction works correctly.
In this case, money is held by the sender until it is received by the beneficiary.
But with the blockchain, this process changes a lot because there is only a single ledger and not two separate databases.
This is similar to Google Docs: what happens when you share a document and users need to edit it?
With traditional text editors users need to transfer the documents back and forth, losing time, energy and likely losing track of the versions.
With Google Docs, instead, all the users involved have access to the same document at the same time, and that document together with the updates are always visible real-time to each of them.
The same thing happens with the Blockchain compared to traditional ledgers.

Smart Contracts through Rootstock, Ethereum and Bitcoin thanks to RSK Labs

Some days ago Rootstock received $1m in seed funding for its own blockchain startup called RSK Labs who provides smart contracts through the bitcoin distributed ledger and compatible with the Ethereum platform.
The funding came from the bitcoin mining company Bitmain Technology and from the bitcoin companies Coinsilium and Digital Currency Group (DCG).
During a recent interview, Diego Gutierrez Zaldivar, CEO at RSK Labs, commented they aim at building a blockchain platform for bitcoin miners and for developers.
Zaldivar said to CoinDesk:
“Our idea is to leverage everything that has been built by the community so far. Not only on the network effect of bitcoin, because the miners will have an additional revenue stream by merge-mining Rootstock, but by providing Ethereum developers a place to build their applications.”
Probably RSK Labs will launch its platform within the end of 2016. 

Smart contracts with the Blockchain

Even if the RSK Labs is very good news, the most important thing we can learn from this event is the interesting development of contracts managed through the blockchain. 
Smart contracts were originally proposed 20 years ago by the famous cryptographer Nick Szabo
A decentralized blockchain with smart contract applications can allow a global financial inclusion, new democratic political systems and the improve of the Internet of things. 
In fact, smart contracts are technology protocols that verify and ease the stipulation of a contract. 
This way smart contracts can provide a better security compared to a traditional contract and allow a significant reduction in transaction fees. Also, smart contracts can provide a service with less risks and without central counterparties.
