Unintended Consequences - CFLs and Greenhouse Gasses

Funny turn-around up North. British Columbia generates about 80% of its electricity from Hydroelectricity. (BC Hydro) So, when people install Compact Fluorescent Lamps in their house (which are heated with Natural Gas) their overall Carbon footprint goes up. From the Vancouver Sun:
Energy-efficient bulbs increase greenhouse gases: BC Hydro
Because they burn cooler, they cause home heating costs to rise, utility reports

Compact fluorescent lights are a darling of the environmental movement, but they're also likely to cause a net increase in greenhouse-gas emissions, according to a BC Hydro document.

Over the past five years, Hydro's promotion of compact fluorescents, or CFLs, has been so effective that British Columbia is now a North American leader in using the energy-saving bulbs.

However, in a recent filing to the B.C. Utilities Commission, Hydro states that widespread adoption of CFLs will have unintended consequences for the environment.

That's because conventional incandescent light bulbs throw off a significant amount of heat, in addition to lighting a room, because they are inefficient users of electricity.

Switch to cool-burning fluorescents and you use less power -- but your house is bit colder so you turn up the thermostat to compensate.

If you live in a house with a gas furnace, you're going to burn more fuel -- and cause more greenhouse gas (GHG) to be emitted into the atmosphere.
You're damned if you do and damned if you don't... Posted by DaveH at February 22, 2009 7:02 PM | TrackBack
