Answer:
Natural gas contains chemical energy
Step-by-step explanation:
Natural gas is a fossil fuel. Fossil fuels are chemical species formed from the decay of plants and animals over many centuries.
Fossil fuels such as natural gas all possess chemical energy. When fossil fuels are burnt, this chemical energy is transformed into heat energy which can be used to turn a turbine.
The turning of the turbine leads to the generation of electricity. Hence by a sequence of energy conversions, chemical energy in fossil fuels can be converted to electrical energy.
