This is a common misconception.
1) reducing electricity consumption will reduce use of fossil fuels in power stations (in most parts of the world). Burning fuel in your own home bypasses the inefficient conversion to electricity.
2) if you are going to heat your home with electricity you can be more than “100% efficient” by using a heat pump, so you still wouldn’t want to do it with light bulbs and TVs.
- holygoat 17y agoHow does using an electric heater instead of waste heat from electrical appliances reduce the use of fossil fuels? Same transport mechanism, same source, same efficiency. The only way to reduce electricity consumption is improved insulation. I agree with you if you have a wood-burning stove.
- imurray 17y agoIf you use a standard electric heater, like a bar heater, I agree with you. Heat pumps can out-perform heaters (they seem to have >100% “efficiency”) by working in a different way. Rather than spending 1kWh to heat a room, you spend 1kWh to move 4kWh of heat from outside into the room.
- Daishiman 17y agoWhat? Power stations are far, far more efficient at converting fuel to energy than home heaters. Large turbines are incredibly efficient, and their design has efficiency as a top priority. Power plants are designed to burn fuel efficiently and transmit as much energy as possible.
