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 said that it is difficult to increase the percentage of firepower because of the prices of greenhouse gases and energy. Therefore, nuclear power plants will have to be below the minimum required percentage, but the share of renewable energy should be at the highest possible level. In Germany, for example, there is a village called win de bio-energy village, which produces energy from crops and livestock excrement 9,000 tons per year and achieve energy self-sufficiency. I would like to mention biogas from livestock waste, which can enable energy self-sufficiency in local villages in Korea.2. BiofuelBiofuel, including biogas, is a source of energy converted by biological organisms. Biofuel includes biogas and bioethanol, which has been converted from components of flora and fauna, synthesis gas from organic waste of animal and plant origin, and solid fuels such as firewood, wood chips and pellets. More recently in Korea, the production of second-generation biofuel, made from livestock waste, food waste and organic sludge, becomes very popular. Biofuel, including biogas, has raised great expectations in terms of the possibility of recycling waste to contribute to energy self-sufficiency and the reduction of greenhouse gases.3.

This is not just a problem for one company, but also a responsibility and opportunity for the entire country. The use of biomass or waste resources in small rural areas not only increases energy self-sufficiency in the region, but also contributes to improving the living environment, such as job creation. For success, I assume that the government must take a phased approach that takes into account efficiency in creating public investment results, to consider the feasibility and creation of tangible results.7.
