Indoor Gas Lighting Today
The use of natural gas (methane) for indoor lighting is nearly extinct. Besides producing a lot of heat, the combustion of methane tends to release significant amounts of carbon monoxide, a colorless and odorless gas which is more readily absorbed by the blood than oxygen, and can be deadly. Historically, the use of lamps of all types was of shorter duration than we are accustomed to with electric lights, and in the far more draughty buildings, it was of less concern and danger. There are no suppliers of new mantle gas lamps set up for use with natural gas; however, some old homes still have fixtures installed, and some period restorations have salvaged fixtures installed, more for decoration than use.
New fixtures are still made and available for propane (sometimes called "bottle(d) gas"), a product of oil refining, which under most circumstances burns more completely to carbon dioxide and water vapor. In some locations where public utility electricity or kerosene are not readily accessible or desirable, propane Gas mantle lamps are still used, although the increased availability of alternative energy sources, such as solar panels and small scale wind generators, combined with increasing efficiency of lighting products, such as compact fluorescent lamps and LEDs are diminishing their use. For occasional use in remote cabins and cottages, propane mantle lamps may still be more economical and less labor intensive than an alternative energy system.

Famous quotes containing the words indoor, gas, lighting and/or today:
“As a man grows older, his ability to sit still and follow indoor occupations increases. He grows vespertinal in his habits as the evening of life approaches, till at last he comes forth only just before sundown, and gets all the walk that he requires in half an hour.”
—Henry David Thoreau (1817–1862)
“When we can drain the Ocean into mill-ponds, and bottle up the Force of Gravity, to be sold by retail, in gas jars; then may we hope to comprehend the infinitudes of man’s soul under formulas of Profit and Loss; and rule over this too, as over a patent engine, by checks, and valves, and balances.”
—Thomas Carlyle (1795–1881)
“Popular art is normally decried as vulgar by the cultivated people of its time; then it loses favor with its original audience as a new generation grows up; then it begins to merge into the softer lighting of “quaint,” and cultivated people become interested in it, and finally it begins to take on the archaic dignity of the primitive.”
—Northrop Frye (b. 1912)
“We do not know today whether we are busy or idle. In times when we thought ourselves indolent, we have afterwards discovered, that much was accomplished, and much was begun in us.”
—Ralph Waldo Emerson (1803–1882)
