Too often, I realise how little I know about this world. I am not talking about details, I am talking about the big picture. The kind of things you would expect to cover on an Earth 101 course in an alien university. So, I look for reasonably well sourced data and visualise them hoping to aid my perspective on life on Earth.

The online services facilitating the occasion, the one-person two-way transportation, the perfect home temperature, and the availability of key items for the night (furniture, devices, clothing, food if you are truly civilised), all require significant amounts of energy to run smoothly. Where does all this energy come from and how do we use it?Explore Energy
