BALLASTS: WE WON!
"Manufacturers finally agreed to an upgrade for the fluorescent
ballast standard in October 1999. Ballasts are components in every
fluorescent light that adjust the incoming electricity to allow
the lamp to work properly. About half of all ballasts currently
sold use modern, energy saving electronic technology while the other
half rely on energy wasting magnetic technology. The new standard,
which becomes effective for most applications on April 1, 2005,
will require all new ballasts to use electronic technology. Magnetic
ballasts will remain available for repairing existing light fixtures
through 2010. Most fluorescent lamps are used in office buildings,
retails stores, warehouses and other commercial buildings.
The new standard will:
- Reduce annual carbon emissions, the main greenhouse gas,
by more than 3 million metric tons 2030.
- Eliminate thousands of pounds of power plant emissions
that contribute to smog, acid rain and other air pollution
problems.
- Save 13.7 billion kWh/yr by 2020, with a net benefit
of $2.6 billion by 2030.
