Efficieny is one thing...
It all seems a little pointless without a major focus on where the energy comes from, switch to hydro, the only major source of renewables at the moment if you ask me, it's generally cheaper than usual & then just stop leaving things on standby! Sorry, just switched myself & realised I save £200 & 2.1 tonnes of CO2 a year, with a computer & monitor running most of the time, makes me feel a lot better about it all.
Big love to you all,
Nick,
