Bjarne Stroustrup, a Danish computer scientist and the creator of C++ programming language, has vented his frustration with use of C++ in Bitcoin mining. "I'm very happy and proud of some of the things C++ is being used at and some other things I wish people wouldn't do, Bitcoin mining being my favorite example - it uses as much energy as Switzerland and mostly serves criminals." Attempts to reduce BTC mining energy consumptionSome industry players have attempted to find a solution to energy consumption in Bitcoin mining. In September, Bitcoin mining infrastructure firm Northern Bitcoin AG completed tests for its new air-cooled mining container.

The company operates BTC-focused mining hardware that uses renewable energy sources and aims to attain optimal efficiency and sustainability. The same month, it was reported that Bitcoin energy consumption was becoming rapidly more efficient. Despite more computing power being dedicated to Bitcoin mining, less electricity was required to fuel it.
