Question

was used for street lighting for the first time in london​

Answer 1

Answer:

Coal gas was used for street lighting for the first time in London in 1810 and in New York around 1820. Now a days, it is used as a source of heat rather than light. These days, bitumen, a petroleum product, is used in place of coal-tar for metalling the roads.
