Jan 03, · As MarketWatch points out, this could make Bitcoin not only more energy intensive, but less energy efficient, as the price spike “has made it more profitable to use less-efficient equipment.”Author: Haley Zaremba. Oct 03, · For one thing, the Antminer S9 (which is used to determine the amount of energy used by Bitcoin) is one of the most efficient Bitcoin miners ever devised. Nov 30, · So Bitcoin should be more sustainable now, right? Or at least the energy situation with Bitcoin is getting better by the year, right? Nothing to worry about right? Not really. More like not necessarily. Just because Bitcoin has become more efficient per transaction doesn’t mean it is a sustainable payment system. Why? There are many reasons.
How to make bitcoin more energy efficientBitcoin Energy Usage: Still A Lot
In the transition to a new energy world - decentralised, digitised and decarbonised - several use case applications have already been developed using blockchain technology, such as automated bill payments, electrical vehicles charging and sharing, and renewable cryptocurrencies. Moving beyond bitcoin - the cryptocurrency most people associate with blockchain - the technology serves as a smart transaction platform at a systematic level that gives rise to true 'prosumers': as well as consumers, households also become producers and sellers of energy with a high degree of autonomy.
Utilities and grid operators become more efficient by being able to balance supply and demand in real-time by engaging these prosumers directly. It supports renewable energy integration into the grid in a cost-effective fashion.
This independent and isolated network solution offers both cleaner and more resilient energy access to its users through its embedded battery storage units. To-date, more than homeowners with or without solar photovoltaic PV systems are already buying and selling power from each other through this platform. In May , several companies joined forces to manage electricity grids in the Netherlands and Germany.
The renewable energy company Vandebron will work with customers who own an electric vehicle to make electricity from their car batteries available to the grid in order to help the Dutch national grid operator TenneT better integrate increasing amounts of renewable energy. TenneT is using innovative IBM blockchain technology to manage this electricity grid.
In the future, blockchain technology could allow millions of energy devices such as water heaters, electric vehicles, batteries and solar PV installations to transact with each other at the electric power distribution edge. The evidence suggests that targeting the risk perception of investors through a variety of instruments is successful in scaling up EE investments. The blockchain peer-to-peer model, which is built on the trust engendered by its permanent and unfalsifiable digital ledger, is a creative financial tool that can help overcome this perception of risky EE transactions.
In the pilot cases implemented to date, more than half of which have been in Europe, blockchain has proven to be a huge cost-saver and efficiency-enabler. By letting go of intermediaries, blockchain transactions lower costs, speed up processes and result in greater flexibility throughout the entire system.
It leads the way to a systemically more efficient, flexible and decentralised energy system. Its transparency, cost-effectiveness and efficiency advantages can lead to more effective stakeholder integration to take concerted actions. The technology is not yet mature, but is growing fast. It might take five to 10 years before the technology reaches mainstream adoption.
Yet it paves the way to an acceleration of energy system decentralisation and the emergence of prosumers, where individuals can adapt their behaviours according to real-time data, and a consequential increase in the overall energy system efficiency. Actions that we take in the coming five to 10 years will lock us in for the next The costs of inaction are rising yearly, with associated economic and humanitarian consequences.
There are 65 million refugees in the world today, 20 million of whom exist thanks to climate change. Should countries not respect the Paris Agreement, South East Asia could become inhospitable to humans by ; one-fifth of the world's population lives in this region.
Sea levels could also rise an estimated 2m by , leading to waves of refugees as two-thirds of the world's population live in coastal areas. Energy efficiency can account for half of the solution to limit the rise in global temepratures to 2 degrees. Though cost-effective, however, its wider application is still hindered by obstacles. Through its transparency, peer-to-peer dimension, trust basis and growing potential, blockchain can smoothen and accelerate EE investments.
Governments should encourage its rise. The views expressed in this article are those of the author alone and not the World Economic Forum.

Harry Kretchmer 06 Jan Each of these PCs, also known as nodes, compete to solve the proof of work algorithm. The one that completes the equation first adds the next block to the blockchain. The node who adds the next block receives a BTC reward for their efforts.
Currently, this reward is As Bitcoin gains popularity, the number of miners on its blockchain increases. A recent report places the number of active miners just north of , You can expect this number to increase as Bitcoin scarcity grows.
Consequently, more miners lead to more electricity consumption. One study found that Bitcoin mining operations consumed 2. To put this massive consumption into perspective, if Bitcoin was a country, it would rank 66 out of in terms of energy usage. You could power 4,, US households with that much electricity, according to the most recent Digiconomist statistics.
Source: bitcoin-energy-consumption. The same statistics show that Bitcoin accounts for 0. Bitcoin mining is on the rise. Last year, the network saw a percent increase in electricity consumption globally. This increased network activity raises the hashrate. In turn, the network difficulty level increases. This difficulty increase could push future Bitcoin transaction energy usage levels from kWh per transaction today, all the way to kWh by the end of the year.
These concerns have led to some individuals pushing for innovative and advantageous solutions. One solution is green energy mining operations. The operation would take advantage of the fact that the Mojave Desert is the 12th hottest place in the world.
According to a recent report published by the research firm Coinshares , renewable energy mining operations are on the rise. This report also shows the migration of miners over the last two years towards more renewable-friendly countries. All of these countries offer more green energy alternatives to potential miners seeking large farm setups.
Another strategy being contemplated by the Bitcoin community is changing from the current PoW consensus mechanism into another option. One such option is the proof of stake PoS algorithm. Instead, nodes are users staking their tokens. In this system, nodes verify the blockchain using their staked tokens as collateral. If a node acts honestly, they are rewarded with more tokens. When a node acts maliciously, they forfeit their tokens.
