sugarcane is referred to as bagasse. Dried bagasse can also be used as fuel (Solway 13). Power plants may burn bagasse to produce electricity. Sugarcane can produce the power needed to keep the ethanol plant running and the sugar to make ethanol. Biogas is produced by dissolving plant and animal material in a closed container. This process uses bacteria instead of yeast. one advantage of

the wood you burn in it is a biomass fuel. Wood waste or garbage can be burned to produce steam for making electricity‚ or to provide heat to industries and homes. BIOFUELS "Biofuels" typically refer to fluid transportation fuels like ethanol‚ biogas and biodiesel that are made from biomass materials – but can include prepared solid biomass fuels. These fuels are: Often blended with the petroleum fuels - gasoline and diesel fuel‚ but they can also be used on their own. o Using ethanol

convert these products to methane and carbon dioxide. Anaerobic digestion is widely used as a source of renewable energy. The process produces a biogas‚ consisting of methane and carbon dioxide. This biogas can be used directly as cooking fuel‚ in combined heat and power gas engines or upgraded to natural gas quality biomethane. The utilisation of biogas as a fuel helps to replace fossil fuels. The nutrient-rich digestate that is also produced can be used as fertilizer. The first anaerobic digester

are conducting research in the area of biogas‚ and it has been successful in many countries because the systems generate heat and electricity from a diverse assortment of waste‚ that eventually would decompose and release methane into the atmosphere‚ bringing benefits to the society and the environment. According to Rosenthal (2010)‚ renewable energy has become more popular throughout Europe. Kristianstad in Sweden has been particularly successful in using biogas because it is an opportunity fuel considering

Therefore‚ fossil fuels used mast be replaced by alternative resource. Alternative resource‚ which found by experts‚ is encouraged to solve the environment polluted problems. Firstly‚ there are many form of renewable source‚ like the solar system‚ biogas‚ wind turbines‚ nuclear power and hydropower energy. These sources can be recycled and they are gentle to the environment. Secondly‚ it is easy to get these alternative sources. In Kristiansand‚ people develop fuel from a variety sources: from an
