Hydrogen Fuel As An Alternative Energy Source To Replace Fossil Fuels Since the beginning of industry humans have been in search of fuel to power machines and generate energy. Fossil fuels‚ such as crude oil and coal‚ discovered beneath the Earth’s surface were found to be an excellent source of fuel. These fossil fuels are burnt in order to generate the energy required to complete various tasks. Many nations count on coal‚ oil and natural gas to supply most of their energy needs‚ but reliance

evaluate ethanol as a fuel‚ the experiments are Fermentation and Calorimetry. Fermentation will find the best combination of sugar and yeast for optimum ethanol production and the Calorimetry experiments test ethanol against other alcohols and fuels to see how it matches up in terms of energy production. Fermentation shows glucose and baker’s yeast as the fastest producers of ethanol and the calorimetry proves that ethanol and other alcohols produce more heat energy than other fuels. Introduction

Here I have listed three examples of biofuels beneath. 1 Micro-organisms decompose waste materials to produce biogas. 2 Biogas is usually about 70% methane and somewhere between 20 and 30 % carbon dioxide 3 the way we use it to generate energy is to burn it to heat up water which will then turn a turbine to produce electricity. It is also heard of to heat the water to steam which
