1. IntroductionIn January 2014, the "second strategic energy plan" was discussed in Korea, according to which the share of renewable energy will increase from 2.7 in 2014 to 11% by 2035. The Korean government mentioned that it is difficult to 'increase the percentage of firepower because of greenhouse gas and energy prices. Nuclear power plants must therefore operate below the minimum percentage required, but the share of renewable energies must be at the highest possible level. In Germany, for example, there is a village called Win de Bio-Energy Village, which produces 9,000 tons of energy from crops and animal waste per year, and achieves energy self-sufficiency. I would like to mention the biogas generated by livestock excretions, which can enable local villages in Korea to achieve energy self-sufficiency.2. BiofuelBiofuel, including biogas, is a source of energy transformed by biological organisms. Biofuels include biogas and bioethanol, which have been transformed by the components of flora and fauna, syngas from organic waste of animals and plants, and solid fuels such as firewood, wood chips and pellets. More recently in Korea, the production of second-generation biofuels, derived from livestock excrement, food waste and organic sludge, is becoming very popular. Biofuels, including biogas, raise high expectations in terms of their ability to recycle waste to contribute to energy self-sufficiency and the reduction of greenhouse gases.3. Production of energy from livestock excreta1) Current status of treatment plant and problem• Current statusMajority of farmers use it as fertilizer with composting facilities on a voluntary basis, and some farmers discharge wastewater from the livestock using marine emissions, and r... ... middle of paper ...... forests and agricultural by-products. This is not only the challenge of one company, but also the responsibility and opportunity of all countries. The use of biomass or waste in small rural areas not only increases the energy autonomy of the region, but also contributes to improving the living environment, such as job creation. To be successful, I assume government must take a step-by-step approach that takes into account the effectiveness of creating results from government investment, to consider feasibility and creating tangible results.7.
