Bitcoin energy consumption is comparable to a medium-sized developed country (~50-75 TWh) and there are doubts that it can be made more sustainable. Another issues related to bitcoin mining are CO2 emissions and generation of electronic waste. The waste is mainly from discarded ASICS, which can be used only for mining Bitcoin – most ASICS end up being incinerated when new models are on sale. In a recent article in Environmental Science and Technology researchers from Aalborg University describe how they “applied Life Cycle Assessment methodology to in-depth analysis of drivers of past and future environmental impacts of the Bitcoin mining network“. In general, energy production and its environmental impact vary widely across the world and when taking into account the geographical distribution of miners and the efficiency of the mining equipment Bitcoin’s energy consumption is much less then previously thought.

Here they come: Peter Rudegeair and Liz Hoffman report in WSJ on Google’s ambitions to move into fintech and banking. The company is launching “Cache”, a service that will allow users opening checking accounts. This follows a similar announcement from Amazon, while Apple is already offering financial services in collaboration with Goldman Sachs. At the same time Facebook is launching Libra, its own digital currency and blockchain technology for payments and financial services, but is facing a significant pushback from politicians and regulators. It is expected that the Google collaboration with Citibank on checking accounts will face similar opposition.
