Answer 2

Answer:

Option C - Coal is the correct answer.

Explanation:

• Fossil fuels, hydroelectricity, and, since the 1950s, nuclear energy have been the primary sources of electricity generation over the last century.
• Despite the rapid expansion of renewables in recent decades, fossil fuels continue to dominate the global energy landscape.
• Coal or oil-fired power plants generate heat, which is then used to make steam, which drives turbines that generate electricity.
• Hot gases drive a turbine to generate electricity in gas plants, whereas a combined cycle gas turbine (CCGT) plant additionally utilises a steam generator to boost the amount of electricity produced.
• In 2017, fossil fuels provided 64.5 per cent of global electricity.

Hence, coal is the most common source of energy from which electricity is produced.
