Answer:

Other alternatives to fossil fuels i can suggest is Renewable energy such as wind and solar energy, especially geothermal energy. Geothermal energy is much more safer than fossil fuels because it doesn't produce greenhouse gases that can harm the atmosphere and environment. Geothermal energy is also a consistent energy unlike wind and solar power.

Nuclear energy is also a good alternative for fossil fuels because it is also safer to the environment and consistent like geothermal energy.
