Renewable and alternative energy sources. Green energy

Abstract

Environmental degradation and depletion of natural resources make us think about how we can get electricity and heat from renewable sources. This article discusses the theoretical foundations and characteristics of RES, analyzes foreign experience and Russian achievements in the organization and development of RES. The analysis showed that on a global scale, the key to energy policy is the transition from environmentally friendly fuels to clean renewable energy sources. Renewable energy sources account for more than a quarter (26%) of global electricity production. Over the past 20 years, the world's electricity production based on renewable energy has increased more than 10 times, solar and wind energy are developing. Thanks to comprehensive policy measures, investments in research and development in the field of alternative energy in Europe, the USA, etc., renewable energy technology has become widespread. Thanks to technological advances in this area, these countries are currently facing a reduction in the cost of electricity generated using renewable energy sources. Despite the world experience, the obvious advantages of renewable energy sources (inexhaustibility of energy resources, environmental friendliness, lack of a fuel component in the cost of energy produced) and their huge potential in Russia, the development of unconventional energy has not been adequately developed. The share of RES in electricity production in the country is 0.2%
