Alternative energy sources to fossil fuels include:
1. Geothermal energy: Geothermal energy is a renewable energy source that harnesses heat from the Earth's core. It can be used to generate electricity and heat buildings. Geothermal power plants utilize steam produced from hot underground water to drive turbines, generating electricity in the process.
2. Natural gas: While natural gas is a fossil fuel, it is considered a cleaner alternative to coal and oil due to lower carbon emissions when burned. It is often used for heating, electricity generation, and as a fuel for vehicles. Despite being a fossil fuel, its relatively lower carbon footprint compared to other fossil fuels makes it a transitional energy source towards more sustainable options.
In summary, geothermal energy and natural gas are alternative energy sources that can serve as more environmentally friendly options compared to traditional fossil fuels like coal and petroleum.
