Approximately 80% of the world's energy is currently provided by fossil fuels, which have been the primary drivers of global economies for the past 150 years. Millions of years ago, layers of mud and rock covered the remains of plants and animals that had died and been buried. Fossil fuels were created due to the huge heat and pressure that resulted from the bones being buried deeper and deeper throughout time. With the discovery of fossil fuels, humankind has advanced in science and technology to a new level. Fossil fuel continues to be the main energy source for that expansion today.
