In recent years, the demand for new energy sources has increased significantly. This shift is largely driven by the need to reduce greenhouse gas emissions and combat climate change. According to the International Renewable Energy Agency (IRENA), the global renewable energy capacity reached 2,800 gigawatts (GW) in 2020, marking a growth of 10.3% from the previous year.
Solar energy has emerged as one of the leading contributors to this growth, with installed solar photovoltaic (PV) capacity exceeding 760 GW globally. This represents a remarkable increase, as solar energy production has seen a year-on-year growth rate of approximately 23%.
Wind energy is another significant player in the renewable energy sector. The total installed wind power capacity reached 743 GW by the end of 2020. The growth of wind energy has been fueled by advancements in technology, which have improved efficiency and reduced costs, making it a more viable option for energy generation.
Hydropower remains the largest source of renewable electricity, contributing to around 16% of the world’s total electricity generation. As of 2020, the global hydropower capacity was approximately 1,200 GW.
Moreover, the transition to new energy sources is expected to continue, with projections indicating that renewable energy could account for 80% of the global energy mix by 2050. This shift will not only help in achieving energy security but also in creating millions of jobs in the renewable energy sector.
In conclusion, the growth of renewable energy sources is a crucial step towards a sustainable future. With ongoing investments and technological advancements, the potential for these energy sources remains immense.
