Abstract
This article examines the importance of using renewable energy, its theoretical foundations, and the practices of developed countries that have adopted it. It reviews their levels of renewable energy use, a statistical analysis of the share of green energy in total energy, effectively addressing environmental problems through the use of renewable energy, and our country's “Green Economy” in the face of current ecological threats. “Renewable Energy” directions, and initiatives being undertaken in this field, and proposals and reflections that could contribute to the further consistent development of this sector were also presented.
According to data from the International Energy Agency, renewable energy accounted for approximately 30% of global electricity generation in 2023, demonstrating a steady increase over the past decade. Furthermore, reports by the International Renewable Energy Agency indicate that renewable energy capacity worldwide reached over 3,700 GW, with solar and wind energy contributing the largest shares.
The article also analyzes the experiences of developed countries such as Germany, Denmark, and China, which have successfully implemented renewable energy strategies. For instance, Denmark generates more than 50% of its electricity from wind energy, while Germany’s “Energiewende” policy has significantly increased the share of renewables in its energy mix to over 45%. China, as the world’s largest renewable energy investor, leads in solar panel production and installation capacity.
A statistical analysis of renewable energy’s share in total energy consumption reveals its crucial role in reducing dependence on fossil fuels, improving air quality, and enhancing energy security. The use of renewable energy sources has been shown to reduce carbon dioxide emissions significantly, contributing to global efforts aligned with the Paris Agreement targets.
Special attention is given to the environmental and economic benefits of renewable energy in addressing ecological issues such as air pollution, climate change, and natural resource depletion. The study also examines the development of the “Green Economy” in Uzbekistan, highlighting national strategies, including the expansion of solar and wind power plants, and government initiatives aimed at increasing the share of renewable energy to 25% by 2030.
In addition, the article discusses current reforms, investment projects, and international cooperation efforts in the renewable energy sector. It outlines practical recommendations for accelerating the transition to clean energy, such as improving regulatory frameworks, increasing private sector participation, enhancing technological innovation, and raising public awareness.
The findings suggest that consistent and strategic development of renewable energy is essential for achieving long-term environmental sustainability, economic growth, and energy independence. The article concludes with proposals aimed at strengthening policy implementation and ensuring the effective integration of renewable energy into national energy systems.
