    In Bitcoin company Coinshares suggested that the majority of Chinese mining facilities were located in Sichuan province, using cheap hydropower for mining Bitcoin.

    The main challenge here is that the production of hydropower or renewable energy in general is far from constant. In Sichuan specifically the average power generation capacity during the wet season is three times that of the dry season. Because of these fluctuations in hydroelectricity generation, Bitcoin miners can only make use of cheap hydropower for a limited amount of time. Using a similar approach, Cambridge in provided a more detailed insight into the localization of Bitcoin miners over time.

    Charting this data, and adding colors based on the carbon intensity of the respective power grids, we can reveal significant mining activity in highly polluting regions of the world during the Chinese dry season as shown below.

    On an annual basis, the average contribution of renewable energy sources therefore remains low. An update on the Cambridge mining map in showed that the share of the network in these areas was already declining prior to the Chinese ban on cryptocurrency mining.

    Key challenges for using renewables It is important to realize that, while renewables are an intermittent source of energy, Bitcoin miners have a constant energy requirement.

    A Bitcoin ASIC miner will, once turned on, not be switched off until it either breaks down or becomes unable to mine Bitcoin at a profit. Because of this, Bitcoin miners increase the baseload demand on a grid.

    In the latter case Bitcoin miners have historically ended up using fossil fuel based power which is generally a more steady source of energy. With climate change pushing the volatility of hydropower production in places like Sichuan, this is unlikely to get any better in the future. According to VISA, the company consumed a total amount of , Gigajoules of energy from various sources globally for all its operations.

    We also know VISA processed With the help of these numbers, it is possible to compare both networks and show that Bitcoin is extremely more energy intensive per transaction than VISA. The carbon footprint per VISA transaction is only 0.

    Electrical Energy Comparison 1,, The number of VISA transactions that could be powered by the energy consumed for a single Bitcoin transaction on average Carbon Footprint Comparison 2,, The number of VISA transactions with a carbon footprint equal to the footprint of a single Bitcoin transaction But even a comparison with the average non-cash transaction in the regular financial system still reveals that an average Bitcoin transaction requires several thousands of times more energy.

    As a new block will be generated only once every 10 minutes on average, this data limit prevents the network from handling more than 7 transactions per second. In the most optimistic scenario Bitcoin could therefore theoretically handle around million transactions annually.

    Meanwhile, the global financial system is handling more than billion digital payments per year and a payment provider like VISA can handle over 65, per second if needed. This is less than the total number of electronic payments processed in a country like Hungary more than million per year , not even considering that cash still makes up for two thirds of all payment transactions here.

    Because of this, the Bitcoin network can consume several times as much electrical energy as the entire country of Hungary which consumes 43 TWh annually. Proponents of the digital currency argue that so-called second layer solutions like the Lightning Network will help scaling Bitcoin, while dismissing that it is practically impossible to make such a solution work on a substantial scale.

    In order to move any amount of funds into the Lightning Network in the first place, a funding transaction on the main network is still required. It would take the Bitcoin network 35 years to process a single funding transaction for all 7.

    The obvious problem with this is that it merely reinvents the system we already have in place. Hence we can also compare Bitcoin mining to gold mining instead.

    Every year, around 3, tonnes of gold are mined, with a total related emissions amounting to 81 million metric tonnes of CO2. When comparing this to the carbon intensity of mining Bitcoins, we can observe that the latter exceeds that of mining real gold see below. Likewise, the comparison is also flawed because we can stop mining for real gold, whereas Bitcoin would simply stop existing without active mining. Gold Mining Footprint The carbon footprint of one Bitcoin's worth of gold mined.

    More energy efficient algorithms, like proof-of-stake, have been in development over recent years. In proof-of-stake coin owners create blocks rather than miners, thus not requiring power hungry machines that produce as many hashes per second as possible. Because of this, the energy consumption of proof-of-stake is negligible compared to proof-of-work. Bitcoin could potentially switch to such an consensus algorithm, which would significantly improve environmental sustainability.

    It is estimated that a switch to proof-of-stake could save Energy consumption model and key assumptions Even though the total network hashrate can easily be calculated, it is impossible to tell what this means in terms of energy consumption as there is no central register with all active machines and their exact power consumption.

    This arbitrary approach has therefore led to a wide set of energy consumption estimates that strongly deviate from one another, sometimes with a disregard to the economic consequences of the chosen parameters.

    The Bitcoin Energy Consumption Index therefore proposes to turn the problem around, and approach energy consumption from an economic perspective. The index is built on the premise that miner income and costs are related.

    Since electricity costs are a major component of the ongoing costs, it follows that the total electricity consumption of the Bitcoin network must be related to miner income as well. To put it simply, the higher mining revenues, the more energy-hungry machines can be supported. How the Bitcoin Energy Consumption Index uses miner income to arrive at an energy consumption estimate is explained in detail here also in peer-reviewed academic literature here , and summarized in the following infographic: Bitcoin miner earnings and estimated expenses are currenly as follows: Annualized Income Total value of mining rewards including fees per year.

    Electricity Costs Assuming a fixed rate of 5 cents per kilowatt-hour. Cost percentage Note that one may reach different conclusions on applying different assumptions a calculator that allows for testing different assumptions has been made available here. The chosen assumptions have been chosen in such a way that they can be considered to be both intuitive and conservative, based on information of actual mining operations.

    In the end, the goal of the Index is not to produce a perfect estimate, but to produce an economically credible day-to-day estimate that is more accurate and robust than an estimate based on the efficiency of a selection of mining machines. Take a second to support Digiconomist on Patreon!

    Today, Bitcoin mining requires powerful computers and access to massive amounts of cheap electricity to be successful. Bitcoin mining also pays less than it used to, making it even harder to recoup the rising computational and electrical costs. How to Use Bitcoin In the U.

    You can also use Bitcoin to make purchases, but the number of vendors that accept the cryptocurrency is still limited. This also generally involves a financial provider instantly converting your Bitcoin into dollars. In other countries—particularly those with less stable currencies—people sometimes use cryptocurrency instead of their own currency. How to Buy Bitcoin Most people buy Bitcoin via cryptocurrency exchanges.

    Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at an online broker like Robinhood. A hot wallet also called an online wallet is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet or mobile wallet is an offline device used to store Bitcoin and is not connected to the Internet.

    Some mobile wallet options include Trezor and Ledger. A few important notes about buying Bitcoin: While Bitcoin is expensive, you can buy fractional Bitcoin from some vendors. Finally, be aware that Bitcoin purchases are not instantaneous like many other equity purchases seemingly are.

    Because Bitcoin transactions must be verified by miners, it may take you at least minutes to see your Bitcoin purchase in your account. How to Invest in Bitcoin Like a stock, you can buy and hold Bitcoin as an investment.

    You can even now do so in special retirement accounts called Bitcoin IRAs. The majority of people that hold it are long-term investors. In Canada, however, diversified Bitcoin investing is becoming more accessible. American investors looking for Bitcoin or Bitcoin-like exposure may consider blockchain ETFs that invest in the technology underlying cryptocurrencies.

    An important note, though: While crypto-based funds may add diversification to crypto holdings and decrease risk slightly, they do still carry substantially more risk and charge much higher fees than broad-based index funds with histories of steady returns. Investors looking to grow wealth steadily may opt for index-based mutual and exchange-traded funds ETFs.
