The family is using compact fluorescent light bulbs and hanging its laundry outside to dry.
Light emitting diodes, or LEDs, could work nicely as replacements for incandescent and compact fluorescent light bulbs.
And finally, we received a flood of e-mail about my story last week on compact fluorescent light bulbs.
They typically last 50, 000 hours, compared with 10, 000 for a compact fluorescent and 1, 000 for an incandescent bulb.
Compact fluorescent bulbs have become a popular alternative, but LEDs have the potential to be twice as efficient.
Going Green can mean sacrifices, like driving less, paying more or enduring the eerie blue of compact fluorescent bulbs.
The major use of terbium is in compact fluorescent light bulbs (the other main one is in phosphors for TV screens).
High cost has thus far limited widespread adoption of LED lighting, which is far more efficient than either incandescent or compact fluorescent lighting.
They seem to be saying that terbium should have run out last year: so that means no more compact fluorescent light bulbs ever.

Remember those bi-partisan Congressional votes phasing out incandescent light bulbs in favor of fragile mercury-laden, landfill-destined compact fluorescent lighting to clearly dispel any such illusions.

Unlike compact fluorescent lightbulbs (CFL), LEDs do not contain toxic mercury.
The intersection of new energy efficiency regulations and the maturation of the technology mean LEDs, which are more efficient than even compact fluorescent bulbs, are the future of lighting.
At the start of this year the firm, which says it sold 137m compact fluorescent lightbulbs in 2007, said it would take further steps to help consumers go green.
The Environmental Protection Agency and some large business, including Wal-Mart, are aggressively promoting the sale of compact fluorescent light bulbs as a way to save energy and fight global warming.
According to IMS Research, collectively, 5.6 billion bulbs light American households and businesses, including 4.2 billion incandescent bulbs and about 1 billion compact fluorescent (CFL) bulbs that contain toxic mercury.
And in one of the coolest art projects we came across this week, Chinese artist Wang Yuyang used thousands of compact fluorescent light bulbs to create a replica of the Moon.
It was also a big week for lighting news as we learned that compact fluorescent light bulbs emit potentially harmful UV radiation -- another good reason to make the switch to LEDs.
This transition has happened with compact fluorescent bulbs.

This means sealing air leaks around windows and doors, properly insulating attics, replacing standard light bulbs with compact fluorescent lamps and giving your heating and cooling systems an annual checkup to ensure they're running properly.
He enjoys stripping down forms, emphasizing silhouette or material, as with the voluptuous Plump sofa (2008), a streamlined, space-age version of the classic Chesterfield, or Bulb (2011), an overscaled, energy-efficient lightbulb designed to challenge the aesthetics of most CFL (compact fluorescent lamp) replacements.
The best-known green-home technology must surely be the compact-fluorescent light bulb, the very icon of green living.
