The article evaluates the biogas as the alternative energy source useful for contributing to the future. Biogas has been found to offer one of the best alternatives due to its economic significance as well as the improved sustainable development through reduced greenhouse gas emissions. The work investigates the production of biogas as an alternative source of energy while outlining its significance in reducing the issues of power energy as well as environmental pollution. The authors analysed the level of bioenergy development in Kazakhstan and around the globe. They revealed that Brazil, China, USA, India and Germany are leaders of bioenergy production in the world. According to the authors, development of bioenergy in Kazakhstan is related to commissioning of new bioenergy stations and supporting sources of renewable energy by government mechanisms. In the case of Kazakhstan, the authors highlighted the fact that existing biogas plants are only used for processing municipal solid waste in urban landfills despite being a major producer of agricultural products.

The article investigates various tools of state support for the development of renewable energy. Special attention is paid to the price instruments of state support for the use of renewable energy sources (RES), including a significant analysis of the regulatory framework of the Republic of Kazakhstan as incentives. The authors analyzed the level of development of fixed rates for the supply of electricity in the Republic of Kazakhstan. The analysis revealed that fixed rates had and continue to have a significant positive impact on the increase in projects for renewable energy. Without the use of this tool in Kazakhstan, it would not have been possible to establish such large RES capacities. The article also deals with the auction system of pricing for the supply of electricity. According to the authors, through the introduction of the auction mechanism, the state selects the most effective RES projects and forms market competitive prices for electric energy produced by RES facilities.
