Why Quebec is betting big on Bitcoin

The current global Bitcoin hash rate, which is to say the total number of mining computations, is approximately 25,,,,,, per second, or 25 million terahashes a second. Without a doubt, electricity is the single greatest expense for any mining operation. And so, to be profitable, farms must be able to source power on the cheap. But increasing government regulation and concern that grid resources could run out have many miners there looking for other places to set up shop.
For years now, China has led the world in greenhouse-gas emissions. The United States, currently the second most popular country for cryptocurrency mining, also gets the majority of its electricity from fossil fuels. Add in the rest of the mining operations around the world, and the industry emits about 29, kilotons of carbon a year, according to Digiconomist, the leading clearinghouse of cryptocurrency and energy concerns.
Bitcoin Mining Part 3: Bitfarms Speaks On The Emerging Blockchain Sector In Quebec
Quimper and his colleagues at Bitfarms had been involved with cryptocurrency in a variety of capacities since They joined forces and established both the company and their mining facilities in late —just in time for the Quebec boom. But the claim that this energy is green has come under increasing scrutiny, particularly from conservation biologists.
They say the impact is far too high for any additional industry, let alone one that produces nothing but bitcoins. Hydroelectric power, which uses moving water to turn turbines that generate electricity, is undeniably cleaner than coal and other electricity generated by fossil fuels. Nevertheless, it, too, produces demonstrable environmental impacts. One of the biggest is the damage created by the reservoirs built to hold a ready supply of water. He was the lead author of a study into the effects of industrialization on northern forests. Researchers have calculated the carbon impact of hydroelectricity worldwide.
Their estimates suggest that if all cryptocurrency mining were to move to this power source, the industry would still generate over 9, kilotons of carbon dioxide each year, plus more than kilotons of methane. And while hydroelectric operations in cooler climates tend to release less carbon and methane than their tropical counterparts, they come with their own unique environmental price tags. Their rivers supply the water that forms the bulk of Arctic sea ice and are believed to be responsible for key ocean currents that transport water and define global weather patterns.

Bitfarms' factories house at least 16, hashing machines between them. Together, they conduct quadrillion attempts every second to solve the single math problem created when a block of Bitcoin transactions reaches capacity.

Hydro-Quebec, the provincial utility, helped the Bitfarms team find locations around the province for mining operations. Then the City of Sherbrooke came knocking with a novel idea for the industry. Cities across Quebec purchase enough electricity from Hydro-Quebec to satisfy peak demands, most often during the dead of winter. But for much of the rest of the year, the energy grids have surplus electricity, and the provincial government has been pushing municipalities to come up with ways to sell the extra power, said Christian Laprise, director of Sherbrooke's municipal power utility.
The deal inked with Bitfarms secures the company 98 megawatts of electricity from Sherbrooke. But Bitfarms will have to reduce operations and use less energy during peak moments of the year when the grid is being taxed by residents. A couple of years ago, Laprise had no idea what Bitcoin and blockchain were, but now he thinks the technology can help develop the digital economy in smaller cities in the province.

Laprise said he hoped companies like Bitfarms diversify "and that they are sustainable over the long-term. Bitfarms says its long-term goal is to expand into other applications of blockchain, but at the moment it's concentrating on building its mining infrastructure. Back in Magog, Grodzki said the broken hashing machine blowing out cold air would be repaired by the company's technicians at its laboratory in St-Jean-sur-Richelieu, Que.
The company's program department created and manages software that tracks the performance of each computer. Their four factories — five when the Sherbrooke operation is operational — run on an electrical system maintained by Volta electrique, a wholly owned subsidiary.
