Solar Energy
an alternative
Only during the day!
No, geothermal energy is not a fossil fuel. It is considered a renewable, sustainable energy source because it utilizes heat from the Earth's core to generate electricity or heating, rather than burning fossil fuels.
Renewable energy sources, such as solar, wind, hydro, and geothermal energy, are alternative options to fossil fuels for generating power. Nuclear energy is another non-fossil fuel source that can provide substantial energy output.
hydroelectric energy is free to the fuel fossil
Wind, hydro-electric, solar, geothermal
oil
Coal IS a fossil fuel
Vegetable oil is renewable, fossil fuel is not.
there running out
Yes However some consider uranium as a fossil fuel for being extracted through mining and in the mean time they consider nuclear energy (using uranium as its fuel) is rebewable energy source for the possibility of producing more fuel (through breeders) than the consumed fissile fuel.
One bad thing about using fossil fuels (coal, oil and natural gas) is that they are causing global warming.Fossil fuels are not a renewable energy source and will eventually run out. They are produced underground which takes years. The problem is we are using fossil fuels quicker than they're made. Its another good reason to use solar energy because the its considered renewable a it will not run out for thousands of years!
