As an energy sector analyst, I am well-versed in the dynamics of global energy production and consumption. It's a complex and ever-evolving field, but I can provide a detailed overview of the primary sources of the world's energy.
The primary source of the world's energy is fossil fuels, which include coal, oil, and natural gas. These fuels are non-renewable and have been the backbone of the global energy system for over a century due to their high energy density and ease of transportation. They are used for a variety of purposes, including electricity generation, heating, transportation, and industrial processes.
Coal has been a dominant force in the energy sector, particularly for electricity generation. It is a relatively cheap and abundant resource, especially in countries like China, India, and the United States. The combustion of coal releases a significant amount of carbon dioxide and other pollutants, contributing to environmental issues such as climate change and air pollution. Despite these concerns, coal remains a significant part of the energy mix due to its affordability and availability.
Natural gas is another major player in the energy market. It is cleaner than coal and oil when burned, emitting less carbon dioxide and fewer pollutants. Natural gas has been growing in popularity, especially with the advent of hydraulic fracturing, or "fracking," which has allowed for the extraction of previously inaccessible reserves. It is used for electricity generation, heating, and as a feedstock in various industries.
Oil is predominantly used for transportation and is a critical component of the global economy. It is a versatile fuel that can be refined into a variety of products, including gasoline, diesel, jet fuel, and lubricants. The oil industry is highly influential, with major oil-producing countries and companies having significant sway over economic and political affairs.
Nuclear power is a significant source of low-carbon electricity. It operates on the principle of nuclear fission, where the nucleus of an atom is split, releasing a large amount of energy. While nuclear power does not emit greenhouse gases during operation, it does come with its own set of challenges, including the management of radioactive waste and concerns over safety.
Hydropower harnesses the power of moving water to generate electricity. It is a renewable energy source that has been utilized for centuries. Large-scale hydroelectric power plants can provide a significant amount of electricity, but they also have environmental impacts, such as altering water flow and ecosystems.
Renewable energy sources, such as solar, wind, geothermal, biomass, and others, are becoming increasingly important as the world seeks to reduce its reliance on fossil fuels and combat climate change. These sources offer a sustainable alternative to traditional energy, with solar and wind power experiencing rapid growth in recent years due to technological advancements and cost reductions.
In 2014, the statistics show that coal was the primary source for electricity generation at 40.8%, followed by natural gas at 21.6%, nuclear at 10.6%, hydro at 16.4%, and other renewable sources combined at 6.3%, with oil accounting for 4.3%. These figures highlight the dominance of fossil fuels in the energy sector, but they also indicate a growing trend towards cleaner and more sustainable energy sources.
The future of energy is likely to see a continued shift towards renewable sources as technology improves and the demand for cleaner energy increases. However, the transition will not be without its challenges, including the need for significant investment in infrastructure, overcoming political and economic barriers, and managing the integration of these new sources into the existing energy grid.

In 2014, the share of world energy consumption for electricity generation by source was coal at 40.8%, natural gas at 21.6%, nuclear at 10.6%, hydro at 16.4%, other sources (solar, wind, geothermal, biomass, etc.) at 6.3% and oil at 4.3%. Coal and natural gas were the most used energy fuels for generating electricity.
