David - Somewhere I read that if every household
in the USA used just one or the newer CF Bulbs. It would Save One Day of Imported Oil per Year. |

What about ''peaker'' plants? |

Every green plant sucks up CO/2 and gives off O/2. And yes trees are cut down,, but all logging companies replant. They arent going to cut their own throats by not replanting. MOST logging companies in the US and Canada reforest.. this is not the case in S. and Central American countries where the forests are being harvested and replaced with cities. |

Indeed Logging here and replanting in varieities that grow fast and soak up CO2 we might soak more CO2 as we build our houses, esp as we build ou r Big houses and the Wood intensive Log facade frame home that the yuppies are put up as vaction home around here |

J A grove of softwood conifers is not nearly as efficient for storing CO2 as an old growth, mixed forest. ''There are four components of carbon storage in a forest ecosystem. These are trees, plants growing on the forest floor (understory material), detritus such as leaf litter and other decaying matter on the forest floor, and forest soils. Carbon is sequestered in the process of plant growth as carbon is captured in plant cell formation and oxygen is released. As the forest biomass experiences growth, the carbon held captive in the forest stock increases. Simultaneously, plants grow on the forest floor and add to this carbon store. Over time, branches, leaves and other materials fall to the forest floor and may store carbon until they decompose. Additionally, forest soils may sequester some of the decomposing plant litter through root/soil interactions.'' |

But those confiers can store it up keep it in stroage in the from of Buildings while growing and absorbing even CO2 In time the Pine can soak up and keep in storage in our home and buildings a lot more co2 than the old growth forest can ''There are four components of carbon storage in a forest ecosystem.

Some Halogen Desk Lighting Systems use a Transformer Yes mine are in a fixture and I would imagine there's some kind of transformer in there. A ''halogen'' bulb is simply an incandescent with gas, rather than a vacuum, inside the bulb. It still uses 90% of the energy going into it to produce heat, rather than visible light. $8 a bulb is way too high for a CF. Try the 5-packs at Home Depot. Even that's too much. CFs are crap. After some of the advertised "long life" ones blew, I started writing the install and fail dates on the white plastic bases. On average, they last anywhere from a tenth to a quarter of the advertised number of hours. As soon as the last of the most recent four-pack fails, I'll send the lot back under the guarantee. I'd spend the refund on incandescents, but they'll probably just send another pack of the same ****. "We're sorry you weren't satisfied with your original cornholing.

The unfortunate truth is, those life estimates (though factual for what they are) are based upon installing a lamp in a test jig, and leaving it to burn until it burns out. The machine has a light sensor and timer and records the amount of time the lamp burns. In the real world, however, we turn our lights on and off, and every time we turn them on, the current inrush significantly decreases the life expectancy of the lamp. If we simply left them on, they'd last pretty much as long as claimed. Look at some of those old incandescents that have been used in inaccessible places without switches, some of which have lasted for decades. |
