Why bitcoin mining needs electricity
Greenidge Generation. A cryptocurrency-mining operation in central New York has reopened a shuttered fossil fuel power plant to power 15, computer servers used to unlock bitcoins, raising concerns among environmentalists, the Associated Press reports. Miners access new bitcoins by solving complex math problems, a task that requires the use of energy-intensive computers. To supply the power needed, Greenidge Generation converted a former coal plant on the shore of Seneca Lake to a gas-fired plant in It started mining at the plant last year, generating 44 megawatts of electricity, largely to supply its operation, with the surplus sold to the grid. The high value of bitcoins is incentivizing such power use.

Iran crypto miners cry foul over electricity backlash
Off a rural two-lane road in Rockdale, Texas, sits the largest cryptocurrency mining operation in North America. The acre Whinstone facility is made up of rows of buildings the length of nearly three football fields. Inside are more than , computer servers mining for Bitcoin. Harris began building the massive facility miles south of Dallas less than two years ago and is currently building four new buildings that will more than double its mining capacity.
Whinstone is just one of several companies that have recently built large cryptocurrency mining facilities in rural Texas — leading some to dub the Lone Star State as the new Bitcoin mining capitol of the world.
The way mining works is whenever someone buys or sells a Bitcoin, a new unique digital coin needs to be made. The computer that does it first produces the new Bitcoin and then is rewarded with Bitcoins for themselves. While Harris noted the local workforce and state tax incentives among his reasons for choosing to build his facility in Texas, he said the key to any large cryptocurrency mining operation is having enough electricity for all the high-powered computers.
When in full operation, the Whinstone facility uses the same amount of electricity as , homes. The electricity it takes to produce a single Bitcoin is equivalent to amount used to power an average Texas home for 62 days. Magnuson, the author of Blockchain Democracy and a cryptocurrency legal expert, said Bitcoin miners are always looking for cheap electricity. Which is why when China recently cracked down on all cryptocurrency activity, many Bitcoin miners rushed to Texas. Less than a mile down the street from Whinstone facility outside Rockdale is another new Bitcoin mining facility, Bitdeer.
Other mining operations have also recently relocated to Texas or are making plans to build facilities often outside rural communities in central and west Texas.
This month the Texas Blockchain Council, an associated with more than 70 cryptocurrency industry members, hosted the largest ever state-wide blockchain summit in Austin. However, while many are pushing Texas to be a leader in the industry, Magnuson said he believes Texas is not ready for this rapid growth.
Now adding onto the grid are several new Bitcoin mining facilities — some highest energy consumption companies in the world. But instead of slowing down the rush, this past session, Texas lawmakers passed several bills enticing more cryptocurrency miners to come to the state.
By using power when no one else needs it, then powering down when electricity demand is high, lawmakers said large cryptocurrency mining facilities can provide stability to the grid. In many cases, Bitcoin miners can make money when turning their power off by selling their electricity back to the grid when demand is high.
Profitability is very important, but it also parallels with being a good corporate citizen. While Whinstone promises to power down when needed, there are no guarantees that every Bitcoin miner in the state will do the same. The state senator said one of the bills she authored created a working group to studying ways to best regulate the cryptocurrency industry.
But while the nature of government is to move slow, the nature of technology moves fast and Bitcoin mining in Texas is in a rush.

Why Is Bitcoin Mining So Energy Intensive?
But in life, many things are actually not what they first seem. This is one of those things. In fact, it is not only not what it seems. It is the exact opposite. First, we need to establish some contextual groundwork. This is a critical step, because lack of clarity on what Bitcoin is and is not, has the potential to muddle an entire subsequent analysis. In that light it seems stupid.
Why does bitcoin consume 'insane' energy?
As new miners join the fray and the Bitcoin network continues to grow, so too does its energy usage. As of mid-July, a single bitcoin transaction required On an average day , , bitcoin transactions are sent over the network. Often referred to as the new gold rush, it can be hard to comprehend how something with no physical manifestation can be so resource-intensive. These miners must compete against each other to win the right to add the next block to the blockchain and earn rewards. The competitive structure results in a lot of wasted energy as only one miner can add a new block every 10 minutes. To maintain a competitive advantage over other miners, many larger operations are forced to scale up or upgrade their equipment. As a result, there are now dozens of mining facilities all over the world that have hundreds, if not thousands, of rigs running constantly. One of the byproducts of these industrial-scale operations is heat. Application-specific integrated circuit ASIC miners — the leading type of specialized computing equipment used for mining cryptocurrencies — produce a lot of heat when performing hashing functions and need to be kept cool to prevent them from becoming less efficient or burning out.
Bitcoin Mining Now Uses More Power Than 159 Countries
Find out in 4 simple steps Go to Energy Opportunity Calculator. Home Insights The cryptocurrency conundrum: the renewables convergence. In our recent article — The cryptocurrency conundrum: The energy impacts, we examined the energy system requirements of bitcoin and other cryptocurrency mining. However, the reality is far more complex than these simple electricity consumption comparisons would suggest. It is also a matter of potential.
Norway could back European Bitcoin mining ban, as minister calls energy use 'difficult to justify'
An obstacle to large-scale bitcoin mining is finding enough cheap energy to run the huge, power-gobbling computer arrays that create and transact cryptocurrency. One mining operation in central New York came up with a novel solution that has alarmed environmentalists. It uses its own power plant. The megawatts dedicated to Bitcoin might be enough electricity to power more than 35, homes. Proponents call it a competitive way to mine increasingly popular cryptocurrencies, without putting a drain on the existing power grid.

How to make cryptocurrency more sustainable
When it comes to Bitcoin, most people think about its current worth or how to get in on Bitcoin trading. However, what you may not think about is the energy consumption of Bitcoin. In comparison to Canada, Bitcoin uses approximately a quarter of the electricity that Canada would consume in a year. The computers that solve each progressively more complex equation receive a reward in bitcoin. However, not every miner will receive bitcoins — every miner needs to fulfill two conditions before being rewarded with bitcoin: 1 The miner needs to verify around 1 MB of transactions and 2 The miner needs to be the first to have the correct answer or closest answer to the complex math problem.

Mining bitcoin and other cryptocurrencies consumes vast amounts of energy. Increasing scrutiny over the environmental impact of this activity recently led the Chinese government to order a crackdown on projects around the country, and now most of them are reportedly already halted. Around 7, terawatt-hours TWh of electricity was produced in China last year. Bitcoin mining in China is estimated to require 86 TWh of electricity per year, or 1.
