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
Greenhouse gas emissions by Turkey NIR p 43) Power stations in Turkey emitted 135 Mt CO2eq in 2016.(ref table 1A(a) sheet 1 in NIR) With an emission intensity of 56tCO2eq/TJ (ref) gas generated more electricity than coal but with less emissions. However as gas is almost all imported it increases the current account deficit. Coal fired power stations emitted 94 Mt CO2eq in 2016 (ref as above). Coal in Turkey is the largest source of the nation's greenhouse gases: in 2015 coal combustion emitted 133 Mt CO. Over a Mt CO is emitted for every TWh electricity generated in Turkey by coal-fired power stations. Once
