currently about 300,000 transactions per day). I happened to come across this study by the Electric Power Research Institute, that judged the annual power consumption for a variety of household devices. Apple has sold 170 million iPads, so all the iPads of the world use.53 terawatt hours per year. Bitcoin mining is the largely automated process ( although it can be done by hand ) of finding a particular hash manier snel geld verdienen met je telefoon value that "solves" a block of transaction data, adding it to an ever-growing chain of blocks that is referred to, appropriately, as the blockchain.

What is Bitcoin's environmental impact? Attaching your hardware investment to an easily discoverable crime doesn't make any sense to save a few dollars a day, at least not for most miners. Regardless of how much energy bitcoin chews through now, those figures are helpful as a baseline, as its consumption is going to increase. There are lots of different bitcoin mining computers out there, but many companies have focused on Application-Specific Integrated Circuit (asic) mining computers, which use less energy to conduct their calculations. Media outlets and blogs have produced various estimates of the electrical energy used in bitcoin mining. Even as an unrealistic lower boundary, this figure is high: As senior economist Teunis Brosens from Dutch bank ING wrote, it's enough to power his own home in the Netherlands for nearly two weeks.
