energy comparison between biofuel and fuel from fossil fuel (term such as calorific value.walt ,joules.will be explained
Answers
Fossil fuels are carbon-based energy sources like coal, oil and natural gas. ... In contrast, biofuels are considered renewable energy sources since corn, soy and other biomass can be grown indefinitely. In the United States, 93 percent of the energy we consume comes from fossil fuels.
A biofuel is a fuel that is produced through contemporary processes from biomass, rather than a fuel produced by the very slow geological processes involved in the formation of fossil fuels, such as oil. Since biomass technically can be used as a fuel directly (e.g. wood logs), some people use the terms biomass and biofuel interchangeably

Biofuels are indeed better than fossil fuels. All biofuels (only hydrocarbons considered here) generate CO2 upon combustion and could therefore be classified as generating greenhouse gas and contributing to global warming similarly to fossil fuels.
Calorific value or heat of combustion of a fuel is the amount of heat developed by a fuel when completely burned. Gross calorific value of fuel oils varies within a comparatively narrow range, highest value of 48 MJ/kg is for light distillate to the lowest value of 42 MJ/kg for heavy fuel oil. Fuel oils are high in hydrogen content, 11.8–14.5%; thus,
The calorific value of biodiesel is about 37.27 MJ/kg. This is 9% lower than regular Number 2 petrodiesel.
