A cryptomining firm is looking to tackle one of the major drawbacks of cryptocurrencies – that of CO2 emissions.
Germany's Bundesrat, which represents the nation's 16 federal states, has voted for a ban on internal combustion engines to be brought in by 2030.
If brought into law, this would mean that the country which invented petrol and diesel powered motors for road transport will also be the first nation to ban their use on the roads. Such a move would also affect plug-in hybrids, with the future belonging to electric vehicles (EVs), whether plug-in or hydrogen cell fuelled.
As the clock ticks down on the Barack Obama presidency it is becoming clear that perhaps his greatest legacy will be in changing the USA from being one of the villains of climate change into a leading advocate of cutting carbon emissions.
Under previous administrations the country was often seen as not only slow in cleaning up its own act, but also as actually guilty of blocking global initiatives to combat climate change. While the USA is still one of the biggest polluters in the world, there is now recognition within many of the States, as well as at a national level, that measures need to be taken to switch to less toxic forms of energy than its traditional reliance on coal.
When it comes to the use of clean energy, Canada is something of an anomaly. While it produces some 59% of its energy needs from hydro-electric projects, it has been slower to take up other forms of renewables such as wind and solar.
This is mainly because it sits on huge reserves of oil, coal and gas - in fact far more than it needs.
