The impact of renewable energy sources on the environment

The use of renewable energy sources is becoming a modern phenomenon that saves energy costs and protects the environment in the long term. The contribution is mapping selected energy and environmental aspects and evaluating renewable energy sources' impact on the environment. At present, energy supply is still mostly provided by sources coming from fossil or nuclear reserves. Although the concept of the "upper limit of exhaustibility" of these resources is increasingly used, there are still disagreements between experts in the field of the life expectancy of the reserves. Population growth means higher consumer demands, which also results in higher consumption of energy resources. Environmental degradation has become a global problem that requires the emphasis of recent studies. Non-renewable energy is a significant factor in environmental degradation. Therefore, policymakers have focused on supporting the production and consumption of energy from renewable sources in all economic activities to ensure a low-carbon economy.
