Handy hints #3 by: JK | Sat 16 Oct

It’s been a while since I posted any hints on energy efficiency, so here goes:

Lighting –

  • Use compact fluorescent lighting where possible right now – yes, I know CFLs have mercury but the mercury produced by burning coal to produce the extra energy to light incandescents outweighs this considerably; …and, yes, you CAN get CFLs that can be dimmed – you just have to look for them;
  • if the colour of CFLs puts you off, look for CFLs with a ‘colour temperature’ between 2500K-3200K or specified as ‘warm white’ – these approximate the colour of incandescents;
  • replace halogen downlights with LED replacements – these are becoming available now and, by doing the changeover, you can use a downmitt to restore a semblance of insulation to your ceiling where your downlights are;
  • use daylight wherever possible – after all, it’s free; 🙂
  • ….and, of course, if no-one is in a room, there is absolutely no need to have the light on, so TURN IT OFF!
  • Be Sociable, Share!
