Broad principles will be used to inform choices of existing technologies e.g. operating … [Read more…]
Introduction Encouraging energy conservation will not be easy. By its nature energy is an abstract and invisible force that is conceptualised or commonly defined in a number of different ways, for example as a commodity, as a social necessity, as an ecological resource, or as a strategic material1.

I think our myopic political leaders, fools, wedded to the idea that tomorrow will be richer (i.e. consume) more than today, where inflation of expectations is, indeed the expectation. Recent discussions about HS2, costing £80bn, and providing fast transport links between cities, is irrational. Our nation makes 4.3billion local bus journeys a year, a number … [Read more…]

Crypto currency energy consumption is circa 73TWh per year which is about the same as the fossil fuel consumption of Nigeria (the most populous country in Africa).
