Fossil fuels are natural fuels formed from the remains of dead plants and animals that were buried and subjected to intense heat and pressure over millions of years. The main types of fossil fuels are coal, oil (petroleum), and natural gas. These fuels are rich in carbon and are non-renewable resources, meaning they cannot be replenished on a human timescale.

Fossil fuels have been the primary source of energy for human civilization for centuries, powering everything from transportation to electricity generation and industrial processes. However, their widespread use has led to several environmental concerns, including air and water pollution, greenhouse gas emissions, and climate change.

Efforts to reduce reliance on fossil fuels and transition to renewable energy sources such as solar, wind, and hydroelectric power are gaining momentum worldwide as societies seek cleaner and more sustainable energy alternatives. Additionally, advancements in technology are making renewable energy sources more efficient and cost-effective, further incentivizing their adoption
