China is the largest crypto miner
China is the world’s largest players when it comes to cryptocurrency mining which has been facing increased scrutiny from authorities that may eventually result in regulating the power used for mining.  China maintains about 60-75 percent of the Bitcoin (available on Coinbase) mining network and, according to Chinese media, 600 Bitcoin (available on Coinbase) miners have been seized in the northern municipality of Tianjin, on the grounds of “electricity theft.” 
One popular way to measure energy consumption is through the Digiconomist Bitcoin (available on Coinbase) Energy Consumption Index. There is the Ethereum (available on Coinbase) Energy Consumption Index, which offers an identical source for ETHer. Currently there is no register where global crypto energy consumption is recorded.
Mining costs keep increasing
Many crypto enthusiasts will go as far as running mining operations from their bedrooms, though the cost for both equipment and energy usage has soared. In order to remain profitable, miners will move to locations where the cost of electricity is cheapest.
For example cheap hydroelectric energy has recently made Sweden and Norway places of interest along with Iceland which has been the focus of crypto miners for some time now. According to an EliteFixtures study South Korea is the most expensive country for mining a single Bitcoin (available on Coinbase), with costs coming in at $26,170 per coin; whereas Venezuela, where the cost per token is just $531, is the cheapest. 
CanADA’s green mining revolution
Canadian firm Hydro Quebec hosts 30 large cryptocurrency miners on its network. The vice president of Montreal International, Stephane Paquet, recently called Quebec a place for “green Bitcoin (available on Coinbase).” According to a recent Reuters report, Hydro Quebec offers some of the lowest electricity rates in North America, charges an industrial rate of $0.0248 per kilowatt hour (Kwh) (2.48 US cents) for data centers and $0.0394/kwh (3.94 US cents) for cryptocurrency customers.
As cryptocurrency mining evolves so will the use of energy.  The increase in cryptocurrency mining pools on a global scale is rapid. Alexander Blair, VP of Engineering at blockchain cybersecurity and smart contract auditing firm, Hosho, explains crypto mining pools have been a natural response to the issue that arises from solo mining – namely that there is massive financial risk in mining alone due to the fact that mining is essentially a game of chance.
Blair said: “Pooled mining solutions allow groups of people to band togETHer to attempt to find a solution, each receiving a piece of the reward. Due to this, increased centralization is expected, however, the issue is not one that can be solved via a technical means, but instead, would need to be solved by a social contract, held by the developers, miners, and owners of pools.”
The evolution of Bitcoin (available on Coinbase) mining chips
For those who want to know more about the mining process.  So far, there’s been three phases of Bitcoin (available on Coinbase) mining:
CPUs 2009 – 2011: In the beginning any laptop or PC could easily mine Bitcoin (available on Coinbase)s. The CPU processor provided the computing power.
GPUs. 2011-2013: As Bitcoin (available on Coinbase) increased in value, the graphics cards contained within gaming PCs were used. These could solve SHA256 problems much more quickly than CPUs but were more expensive.
ASICs. 2013 onwards: Finally, as Bitcoin (available on Coinbase)’s value soared to over $1000 USD in 2013, purpose built mining hardware was created to mine Bitcoin (available on Coinbase). ASIC computers were much more powerful and efficient at mining than GPUs, and are now what keep the Bitcoin (available on Coinbase) network running. They are however, very expensive, and have been criticised because most people cannot afford them.
