MILWAUKEE --
The Twinkle and glow of the family decorated with festive lights reminds Adam Siegel of carbon emissions and global warming, not warmth and cheers.
Siegel insisted that he was not a man who would only grind grin.
"You can have beautiful displays, gorgeous displays, and even huge displays, but why is it wasted?
Siegel, a blogger from Va McLean, said.
There are signs that after years of struggling with holiday sales for energy-efficient LED lighting, more and more people feel the same way.
Manufacturers and retailers across the country report that sales are surprisingly active even during the recession.
For example, light-
Osram siwania, a light bulb maker, said its LED sales have doubled since last year to 15 million to 20 million units. LEDs, or light-
LEDs are three times more expensive than conventional incandescent lamps, but they consume 90% less energy, resulting in less heat and longer duration.
Siegel did math on his blog GetEnergySmartNow.
Not associated with any energy or lighting company.
He calculated that an average string of LED lights would save enough energy to pay for himself within a year.
Calculations by other independent researchers indicate
Depending on how long the lights are left, even points can be two to three years.
No matter who is doing math, the upfront cost of LED lighting is almost always worth investing in, especially as more utilities invest in additional incentives, each can range from $2 to $4.
The first ones to turn to LED lights are big companies or municipalities that can save most people.

"The government replaced traditional lighting on the National Christmas Tree in Washington, DC. C.
Now there are 37,000 LED lights.
The Christmas tree at Rockefeller Center in New York is decorated with 30,000 LED lights on 5 miles of wires.
LEDs are miniature semiconductors similar to computer chips and are commonly used for traffic signals, rail lighting, and electronic devices.
LED lights are more efficient because most of the energy in the circuit is converted into light, while up to 90% of the energy emitted by incandescent lamps is wasted as heat.
They are stronger and last 10 times longer than incandescent lamps, and there is no fire hazard because they are not that hot.
For some, the price of green bulbs is still an obstacle.
Amazon, for example.
Com sold a string of 100-color LED solar-saving lights for about $28, while incandescent lamps cost about $10.
Even so, 21 of Amazon's top 25 holidays

Companies can even use solar technology so that the lights don't have to be grounded.

Nagatani, an employment lawyer in the Bay Area of San Francisco, said it makes no sense to spend a long timeterm view.
"I will buy the cheapest one on the shelf," said Nagatani, 33 . ".
"I mean, you only take it out once a year for three weeks.
Still, cities like the Palm Desert of California
Years of energy use must be balanced
Turn to push residents to switch.
Last year, the city offered residents a string of LED lights for free in exchange for traditional lights.
Between 2007 and this year, the number of swaps has tripled from 568 to 1,748.
"In the desert, you can imagine that energy usage is high, like air conditioning in August," says Patrick Conlon, who leads the city's energy management office.
"We did this to inspire enthusiasm for energy efficiency, and we were pleasantly surprised by how well it worked.
He said: "The project costs about $26,000 this year, and if the interest is still so high, the city may have to consider a rebate for next year instead of a free alternative.
