Biogas produces less smoke than natural gas, which is one of the reasons it's considered a more environment-friendly energy source. Waste-to-Energy. Waste to energy facilities can use this waste to produce gas, energy generation, and create electricity and heat, and other fuels. . 2) It helps reduce carbon emissions significantly. Overall, waste to energy is a good option for communities looking for a . Reduced Energy Consumption. In the case of waste-to-energy, . Wind energy is produced when the wind blows; thus, it is necessary to store the energy in batteries in order to have electricity when there is no wind. Renewable energy won't run out. Release of hazardous gases. Renewable energy technologies use resources straight from the environment to generate power. Landfills are the reason why pests and diseases take place. The study also reasons that energy from waste can no longer be considered a "low carbon technology" in the UK, largely because electricity generation is becoming more decarbonised. The European Commission's recently published clean energy investment agenda seeks to drive the transformation of its energy system "which accounts for 75% of the EU's greenhouse gas emissions".. Potential energy of the water stored In a dam changes to kinetic energy to drive turbines. More pollution and energy consumption. Advantages. - reduces energy and mineral use and air and water pollution. Elimination or Reduction of Landfills from Waste Volume Reduction. The disadvantages of waste-to-energy are numerous and have become more apparent in recent years. Advantages: These systems have many benefits which could be direct or indirect. Surplus energy recovery is possible from the system. Clean energy - Solar energy is also a totally clean energy . Direct benefits: The recovery process will add to the efficiency of the process and thus decrease the costs of fuel and energy consumption needed for that process. From theconversation.com: Some see incinerators as a 'false solution to climate change that diverts precious resources, time and attention from more systemic solutions . - can cost more than burying in areas with ample landfill space. Generation of electricity. Other sources, such as municipal waste and organic waste, can be considered renewable energy sources. As plasma pyrolysis is currently a new ray of hope for us for plastic and bio-medical waste treatment.
