If a shortage of coal were to cause an increase in coal prices, how would it most likely affect renewable energy sources like solar energy?

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.

a chemical change results in a new substance being formed; whereas a physical change will result in a different state of matter

observation, evidence
