Stronghold Digital Mining (SDIG), a crypto mining company in Pennsylvania, is turning waste from old power plants into energy to power hundreds of Bitcoin mining rigs. The company collects coal refuse, a leftover waste material from the process of coal mining, and burns it in what it says is an emissions-controlled environment at its energy generation facilities. Coal refuse can cause a raft of environmental problems, such as water and air pollution, and acid mine drainage, the acidic water which comes from coal mining operations. Collecting this waste and safely disposing of it while generating power for crypto mining is …

Republican Congressman Pete Sessions from Texas has come out with a bold statement about the impact Bitcoin mining will have not just on his state but on the United States as a whole. The Texan representative, a proponent of Bitcoin (BTC) mining, tweeted on March 22 that “Bitcoin Mining will play a critical role in rebuilding energy independence in the USA.” His statement drew a mixed bag of reactions from both supporters and critics. Wyoming’s Republican Senator Cynthia Lummis was among the supporters who responded to his tweet with a succinct “Indeed.” #Bitcoin Mining will play a critical role in …

The energy usage and environmental impact of Bitcoin (BTC) mining have been frowned upon and been under the scanner by various international financial institutions. The International Monetary Fund (IMF) mentions how Bitcoin mining consumes “vast amounts of computing power and electricity.” Bitcoin mining is an energy-consuming process, as it is a proof-of-work (PoW) blockchain network that involves providing cryptographic proof to the network that a quantified amount of a specific computational effort has been used. The information used to verify this is stored in a block to be accepted into the network by other participants. Elon Musk, one of the …

Bitcoin (BTC) miners are holding more and more Bitcoin while “relentlessly expanding” their operations in 2022. A report by Arcane Research indicates that publicly listed Bitcoin miners are “constantly looking for expansion opportunities,” as they “plan to increase hashrate faster than the whole network in 2022.” 44.95% of the global hash rate derives from North American miners, according to the latest figures from the Cambridge Bitcoin electricity consumption index. With the massive projected increases in target hash rate among the publicly traded Bitcoin miners, it's "likely to increase." Jaran Mellerud, an analyst for Arcane Research, told Cointelegraph that “most publicly …

One of the main themes among the crypto community in 2021 was China’s aggressive policy toward mining, which led to a complete ban on such activities in September. While mining as a type of financial activity has not gone away and is unlikely to disappear, Chinese cryptocurrency miners had to look for a new place to set up shop. Many of them moved to the United States — the world’s new mining mecca — while some left to Scandinavia and others to nearby Kazakhstan, with its cheap electricity. Mining activities can’t stay under the radar forever, and governments around the …

Bitcoin (BTC) mining generates a lot of “waste” heat. As energy prices spiral out of control in Europe, miners have come up with creative ways of recycling the heat generated by solving valid Bitcoin blocks. Whereas in Norway, a miner is drying wood from the local timber mill, across the North Sea in the Netherlands, a miner is heating greenhouses to grow produce and bloom “Bitcoin flowers.” In a win-win partnership between a Dutch farmer and a Bitcoin miner, Bitcoin Bloem mines Bitcoin and bud flowers in greenhouses in the province of North Braband, southeast of Rotterdam. It works like …

El Salvador, the first nation to adopt Bitcoin (BTC) as legal tender, has recently announced the relaunch of its wallet app Chivo, which is supposed to patch the previous version’s stability and scalability issues. The update is welcomed news for the Central American country’s crypto experiment, which faced some hurdles and harsh criticism over the last few months. While much of the observers’ attention has been focused on aspects such as retail adoption of crypto and geopolitical implications of Bitcoin’s legal status in El Salvador, the progress of the nation’s mining industry toward achieving President Bukele’s moonshot vision has been …

Solana (SOL), one of the most active proof-of-stake (PoS) blockchains, appears to be a PoS protocol consuming the lowest amount of electricity per transaction, according to a new report. The Crypto Carbon Ratings Institute (CCRI), a research startup focused on the environmental impact of cryptocurrencies, released on Wednesday a new report calculating the electricity consumption and carbon footprint of major PoS blockchains. The CCRI specifically analyzed PoS networks including Cardano, Solana, Polkadot, Avalanche, Algorand and Tezos. According to the CCRI’s findings, the Solana blockchain consumed 0.166 watt-hours (Wh) of electricity per transaction within the study, becoming the most energy-efficient PoS …

On Jan. 27, a group of eight U.S. lawmakers, led by Senator Elizabeth Warren, sent letters to the world’s six largest Bitcoin mining companies, demanding to reveal the detailed data on their electricity consumption. This isn’t the first time Senator Warren requested this information from a mining operation — last month a similar letter was sent to Greenidge Generation, which uses a natural gas plant to power its facility. These moves highlight the increasing regulatory pressure on crypto mining businesses in the United States. But, as last week’s Congress hearing showed, the growing scrutiny might turn out to be an …

Bitcoin (BTC) seems to be on everyone’s mind lately as the world recently witnessed the price of BTC take a rather unexpected bearish turn this month. On January 21, 2022, Bitcoin reached six-month lows, sinking below $40,000 for the first time in months. While some panicked, other industry experts pointed out that the Bitcoin network has become verifiably stronger than ever before. The growth of the Bitcoin network has become apparent, as hash rate figures for BTC continue to set new highs this month. For example, on Jan. 22, the BTC network recorded an all-time high of 26.643 trillion with …

It was only a matter of time before China slapped a ban on Bitcoin (BTC) mining, trading and crypto services. To do anything with Bitcoin anywhere in the People’s Republic, one needs a special exemption. The Chinese government’s given reason for the Bitcoin crackdown is to reduce its well-documented climate impact. Regardless of the amount of truth in this explanation, one thing is clear: China’s righteous anger toward electricity-guzzling and carbon-spewing mined cryptocurrencies in the service of Earth’s climate is only the first shot in an impending global showdown over Bitcoin and other crypto projects that rely on proof-of-work (PoW), …

Five industry experts appearing before the United States House Energy and Commerce Oversight Subcommittee had different views on how lawmakers should address the energy consumption of cryptocurrencies. In written testimony released before a Thursday hearing on “Cleaning Up Cryptocurrency: The Energy Impacts of Blockchains,” former Comptroller of the Currency Brian Brooks argued that the energy consumption of Bitcoin (BTC) mining was “economically productive” given other assets including gold required roughly the same amount of energy for mining, with the “a host of other environmental concerns.” In addition, Brooks said that the traditional global banking system consumed roughly 2.5 times the …
