Electrical Generation: A Global Breakdown
Solar Power: The Fastest-Growing Source
In 2020, solar power accounted for 2.4% of global electricity generation, up from 1.2% in 2010. China is the largest player in the solar market, generating 55% of the world’s solar electricity. The United States, Japan, and Germany are also major solar producers. Solar power is the fastest-growing source of electricity generation, driven by declining costs and increasing adoption in developed markets.
Wind Power: A Close Second
Wind power is the second-largest source of renewable energy, accounting for 6.5% of global electricity generation in 2020. The United States is the largest player in the wind market, generating 18% of the world’s wind electricity. China, Germany, and India are also major wind producers. While wind power is less widespread than solar power, it remains an important contributor to the global energy mix.
Hydroelectric Power: A Legacy Source
Hydroelectric power remains the largest source of renewable energy, accounting for 16.3% of global electricity generation. China is the largest producer of hydroelectricity, followed by Canada, the United States, Brazil, and Russia. Hydroelectric power is a mature technology, but new investment is still being made in the sector, particularly in emerging markets.
Geothermal and Biomass: Niche Players
Geothermal and biomass power plants generate 1.2% and 1.1% of global electricity, respectively. These sources are niche players, but they still play an important role in the global energy mix. Geothermal power is more significant in certain regions, such as the Philippines and Indonesia, while biomass power is more prominent in Europe and North America.
Nuclear Power: A Declining Source
Nuclear power accounts for 10.5% of global electricity generation, down from 12.3% in 2010. While nuclear power is still an important source of electricity, concerns over safety and cost make it a less attractive option for many investors.
Conclusion
Electricity generation is a diverse and complex landscape, with various sources competing for attention. Solar and wind power are rising stars, while hydroelectric and nuclear power remain mature players. Geothermal and biomass power occupy niche roles, but still contribute to the global energy mix. As investors, understanding the global distribution of electrical generation is crucial for making informed decisions.
