SOLUTION

• Environmental impact: The burning of fossil fuels, which currently provides the majority of the world’s energy, is a major contributor to air and water pollution and climate change. Greenhouse gas emissions from the energy sector are the largest contributor to global warming.
• Limited resources: Fossil fuels, such as coal, oil, and natural gas, are finite resources that will eventually be depleted. This means that we will eventually need to find alternative energy sources.
