It can be mixed with gasoline to any percentage and used in existing petrol engines as a replacement of gasoline. Biodiesel is beneficial because it can be used in existing vehicles with little or no adaptation.
Solar panels can be used in homes instead of electricity which is generated using fossil fuels.
Using mass transportation like train,bus,metro instead of personal car could reduce the use of fossil fuel.
Using alternate energy sources like solar power,tidal power ,wave energy,wind energy,hydro thermal energy ,geothermal and nuclear energy could definitely reduce the use of fossil fuels.
