A cryptomining firm is looking to tackle one of the major drawbacks of cryptocurrencies – that of CO2 emissions.
Offshore wind farms have become increasingly popular as a source of renewable energy over recent times and now floating turbines look set to vastly expand their geographical reach.
Up until now offshore wind farms have been restricted to shallower waters, less than 50 metres deep, as the turbines were installed on foundations laid directly on the seabed. But now their younger siblings are heading for deeper waters.
Transportation accounts for about 20% of CO2 emissions in the Netherlands, so the revelation that its train system now runs on 100% renewable energy is good news in the fight against climate change.
In keeping with the Dutch railways' reputation for good time keeping, the deadline for the moment the trains became 100% sustainable (at least in terms of power) wasn't just met, but was beaten by a full year.
Pellworm - dubbed Europe’s smartest island – stands as proof that an entire community can depend on wind and solar energy alone for its power needs after the first phase of a smart-grid research project was completed.
The Frisian island - situated near the German-Danish border – was selected by power company E.ON for a feasibility study into using battery storage systems to smooth out electricity supply and so cut the 1,200 strong community’s reliance on importing power via under-sea cables to meet peak demand.
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.
For many people the advantage of renewable energy production would appear to be simply one of ecological factors, but to the people of Ukraine it goes far beyond simply being 'green'.
For them the conflict and political turbulence the country has endured over the past few years with their powerful and at times hostile neighbours, Russia, has made the issue of solar, wind and other renewables a matter of strategic national importance as they seek energy security.
