Turn off every other light, or, better still turn off two, have one on, turn off two etc. Initially there would be a cost of putting in two wiring circuits but this would eventually recoup itself. That said the saving would be insignificantly small in that that is achievable by improvements in efficiency of generation, lighting and transmission systems. Whilst we are energy hungry and present methods of generation are polluting – the answers are out there to turn it all around. Changing from a coal fired generator to a gas one would halve the pollution and changing to nuclear, or alternative power sources would wipe it out.

If people would only look beyond their irrational fear and quantify the real dangers they would see that the risks of rape, burglary and murder are tiny. They are far more likely to die in an accident in
