By 2012, inefficient incandescent light bulbs will not be sold. Compact fluorescents will be part of the future, among other options.

The new energy bill signed this week makes it official. When 2012 hits, stores can no longer sell the cheap but inefficient incandescent light bulbs that are fixtures in most homes.

Even so, light bulb manufacturers say that worries about greenhouse gases and the high cost of energy had them moving away from conventional incandescents way before Congress weighed in. For quite some time, they note, they have been trying to soften the light emitted by compact fluorescent lights, bring down the cost of light-emitting diodes — and yes, find ways to increase the efficiency of incandescents.

Many of the products are already on the market, and more will be available before the deadline kicks in,

“Sure, you’ll see more compact fluorescents five years from now, but you would have seen them without any energy bill,” said the chief executive of Osram Sylvania, Charlie Jerabek.

Michael B. Petras Jr., vice president of GE Consumer and Industrial — the unit that includes General Electric’s lighting business — broadened the thought to all forms of lighting. “You’ll see different light sources for your decorative chandelier, for your recessed lighting and for your under-cabinet lights,” he said. “And I can assure you that all the kinds of light sources are already getting a lot more efficient.”

Including incandescents.

Congress has not specifically outlawed incandescent bulbs, only inefficient ones.

In February, G.E. said that it was developing a high-efficiency incandescent that will radiate more than twice the light of conventional incandescents. It expects to make that one commercially available by 2010, and one that is twice as efficient a few years later.

And so far, consumers have been slow to give new products a chance. Compact fluorescents, for example, are already ubiquitous in stores. Many retailers, led by Wal-Mart, have promoted the economics of the bulbs — though compact fluorescents generally cost six times what incandescents do, they last six times as long and use far less energy.

The EnergyStar program of the Environmental Protection Agency has been pushing compact fluorescents for almost nine years.

“People realize that incandescents are an old, inefficient technology,” an EnergyStar spokeswoman, Maria Vargas, said.

The promotions have had modest success. Mr. Jerabek said Sylvania’s sales of compact fluorescents doubled in 2006 over 2005, and doubled again this year. But, he notes, they still account for 15 percent of bulbs in use in homes.

Sylvania recently introduced a fluorescent that Mr. Jerabek said mimicked the light of incandescents. He concedes that incandescents are about 10 percent warmer, but he insists that “the average consumer would have trouble detecting the difference.”

Compact fluorescent lights have problems beyond light quality. They contain mercury, and few recycling centers will accept them. So at the end of life, they still pose an environmental hazard.

“We’re working to reduce mercury, but the amount will never go to zero,” Mr. Petras said.

That is why Mr. Jerabek, for one, calls compact fluorescent lights “a temporary fix.”

Manufacturers are putting a lot of stock in light-emitting diodes — or L.E.D.’s. They operate with chips made of nontoxic materials and last for about 50,000 hours, compared with 1,000 hours for an incandescent and 6,000 for a compact fluorescent. A tiny L.E.D. can shed as much light as a cumbersome bulb, which makes them easier to integrate into a home’s décor. And, they are extremely energy efficient.

But today, they are too expensive to use for all lighting applications. And, while manufacturers are able to make pretty good colored L.E.D.’s — the kind that are already available for Christmas tree lights — they have yet to perfect a white L.E.D. that would be useful for lighting homes.

Manufacturers are working to get the costs down and the white lighting quotient up. Most predict that white L.E.D.’s will be commercially viable in a few years.

“Most C.F.L.’s meet the EnergyStar specs now, and all of us are optimistic about the prospects for L.E.D.’s,” Ms. Vargas said.

But even though the energy bill has not changed the direction of lighting research, most manufacturers are relieved to have a federal standard in place.

“If each state passed its own rules for light bulb efficiency, we’d have to make 50 different types,” Mr. Jerabek said. “Now we can all standardize our production techniques.”

There are many good reasons to conserve energy. If we use less gas, oil and electricity we will save money, and the pollution associated with extracting and using fossil fuels will decrease. Reducing greenhouse gas production may help to reverse global warming. In a nutshell – conservation of energy has both personal and societal benefits.

Most people are concerned with making their money last longer and energy conservation can help by reducing our energy costs. Homeowners can do many things to cut down on their energy needs. Perhaps the best thing they can do to is to install better insulation to retain warm and cool air.

Heating and air conditioning are the biggest energy consumers of the average household. Much of the heat and cool air escapes because of poorly insulated roofs, walls, doors, and windows. In fact in a lot of cases heating and cooling is responsible for around 50% of your energy costs. Improving insulation will result in greater conservation of energy and lesser energy costs. Small changes in this area can result in dramatic reduction in your monthly payment to your utility company.

Old cooling and heating appliances should be replaced with newer models which are more energy efficient. Other large appliances like refrigerators can also be replaced with newer models that are designed to conserve energy. Always make sure you read the energy label, if you do, you will often find that a cheap product in fact can be expensive in its every day use because of its energy consumption.

Traditional light bulbs are inefficient because much of the energy they consume is converted to heat. Replacing all your incandescent bulbs with compact florescent bulbs will provide the same level at light with less energy consumption. Even though the cost of these bulbs is greater than traditional bulbs, they last up to 20 times longer, resulting in significant overall savings.

Using alternative energy sources such as solar panels or wind turbines can greatly reduce the amount of energy needed from traditional sources. The electricity produced by these devices can be fed back into the local power grid if it is not immediately used by the household. This reduces the power bill even further (the power meter runs backwards) while supplying clean power to your community.

Conservation of energy is not just for homes, cars and trucks are available with more energy efficient engines and some can run on alternate power sources such as hydrogen or electricity.

Conservation of energy is something that everyone can contribute to. By being careful in how we use our resources we are building a society for our children and grandchildren.
