Gas lighting explains why a large number of older gas lamps have been converted to electricity. Solar-rechargeable battery-powered gas light controllers can be easily retrofitted into existing gas lamps to keep the lights off during daylight hours and cut energy consumption and green-house gas carbon emissions by 50%. 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
Southern California Gas Company the Los Angeles Gas Company in 1890. These companies ultimately became Southern California Gas Company. By the early 20th century, natural gas—a colorless, odorless gas found in association with oil underground—was starting to gain attention. The breakthrough came with the discovery of the Buena Vista Oil Field near Taft, California in 1909, which included a huge reservoir of natural gas. Since natural gas had twice the heating value of manufactured gas, the company took the bold step to convert its system to natural gas and build pipelines throughout the state. Natural gas was soon found throughout the country, and demand
