Seeing the future, and ignoring it. An inconvenient truth.
For a few years last century, for reasons which will not become clear again for some time, I became familiar with some activities of one of the UK's most energy intensive (and yet potentially most energy efficient) industries.
Specifically, the glass industry. Some seriously good work on reducing their dependence on expensive energy was done, but I don't know where it eventually led, as the main player in this sector was, like so many others, taken over by an overseas company to feed the appetites of the City moneychangers and their stooges in the boardrooms.
Reduce reuse recycle.
