Hello!

Heating with electricity generated from fossil fuels (which is how 50% of the electricity is generated in my part of the world) is expensive for everybody on this planet, not only the one who directly pays the electricity bill. Even the present occupant of the white house had to finally admit that a short while ago. And don't forget about those parts of the world where cooling is required instead of heating. Removig one Joule of heat costs three to four joules of electricity if the air condition is powered electrically (and most of them are). Generating one Joule of electricity from burning fossile fuels again consumes about three Joules of stored chemical energy. And overall efficiency below 10%. Which means that a 100W incandescent bulb in an air conditioned building requires the equivalent of 1kW of coal, oil or natural gas to be burnt (or Unranium atoms split) on the other side of the cable. Replacing those bulbs with LEDs pays off big time! Regards Max |
