Renewable energy sources: the key for sustainable future

Using renewable energy sources plays a key role in addressing the growing challenges of climate change. The increase in global temperatures is now an undeniable fact. The extreme weather events, such as prolonged drought, hailstorms, forest fires, and floods have made the switch to sustainable energy sources – such as solar, wind, and hydro – a viable alternative to reducing dependence on fossil fuels, particularly coal, oil and gas. This article examines how renewable energy can help reduce greenhouse gas emissions in the atmosphere, improve energy security, and contribute to the global initiatives and support Bulgaria`s participation in global initiatives aimed at achieving a low-carbon future. It also looks at the economic and social benefits of clean energy deployment and the challenges that hinder its widespread implementation. The study also analyzed the dynamics and trends in the development of renewable energy sources in the EU and Bulgaria. The study is based on EUROSTAT data and examines legislation and reports related to the topic. The results indicate that, despite a 22.8% increase in the share of clean energy derived from renewable energy sources by the end of 2023, the share of coal-fired power in Bulgaria remains significantly high. This poses a major challenge to achieving the climate targets outlined in the Paris Climate Agreement and the Green Deal. Keywords: climate change, greenhouse gas emissions, low-carbon future
