In the interactive chart shown, we see the primary energy mix broken down by fuel or generation source. Globally we get the largest amount of our energy from oil, followed by coal, gas, and hydroelectric power. However, other renewable sources are now growing quickly. These charts show the breakdown of the energy mix by country.
READ MOREChina continues to add new coal-fired power plants to the grid, with 11 GW added in 2022, driven by energy security concerns, local economic interests, and tendency to pair dispatchable power sources with variable
READ MORESolar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun''s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of
READ MOREThe wind, the sun, and Earth are sources of renewable energy . These energy sources naturally renew, or replenish themselves. Wind, sunlight, and the planet have energy that transforms in ways we can see and feel. We can see and feel evidence of the transfer of energy from the sun to Earth in the sunlight shining on the ground and the

READ MOREWhile growth in coal investments is slowing and COVID-19-induced electricity demand reductions have cut coal-fired electricity output in 2020, coal use is
READ MORECoal takes millions of years to form. Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.
READ MORERenewable energy is energy from sources we cannot run out of. Some types of renewable energy, like wind and solar power, come from sources that are not depleted when used. Others, like
READ MORERenewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly
READ MORERenewable resources include biomass energy (such as ethanol ), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals. This includes

READ MOREHydropower is the world''s biggest source of renewable energy by far, with China, Brazil, Canada, the U.S., and Russia the leading hydropower producers. While hydropower is theoretically a clean
READ MOREPetroleum. Hydrocarbon gas liquids. Natural gas. Coal. Nuclear energy. These energy sources are called nonrenewable because their supplies are limited to the amounts that we can mine or extract from the earth. Coal, natural gas, and petroleum formed over thousands of years from the buried remains of ancient sea plants and
READ MOREThe chart below shows the percentage of global electricity production that comes from nuclear or renewable energy, such as solar, wind, hydropower, wind and tidal, and some biomass. Globally, more than a third of our
READ MORERenewable fuel sources include sunlight, wind, moving water, biomass from fast-growing plants, and geothermal heat from the earth. The lifespan of renewable resources looks like a
READ MORESolar PV and wind account for 95% of the expansion, with renewables overtaking coal to become the largest source of global electricity generation by early 2025. But despite the unprecedented growth over the past 12 months, the world needs to go further to triple capacity by 2030, which countries agreed to do at COP28.
READ MOREGlobal coal consumption reached an all-time high in 2022 and the world is heading towards a new record in 2023. Global coal demand reached a record high in 2022 amid the global energy crisis, rising by 4% year-on-year to 8.42 billion tonnes (Bt). In 2023 we expect coal demand to fall in almost all advanced economies.
READ MORE"It''s harder to merge solar and wind power with the electricity grid" than to include coal-based power, says Hong Li. Renewable energy is "less reliable and that can make the grid unstable
READ MOREIn this interactive chart, we see the share of primary energy consumption that came from renewable technologies – the combination of hydropower, solar, wind, geothermal, wave, tidal, and modern biofuels. Traditional biomass – which can be an important energy source in lower-income settings is not included.
READ MORERenewable energy sources as an alternative energy source in South Africa can seriously reduce the over-reliance on coal which is a finite and environmentally unfriendly resource. Furthermore, the development of the renewable energy sector in the country has the potential of creating more job opportunities thus improving the South

READ MOREA widely-available but non-renewable resource, coal is still the second-largest source of energy in the world and the most-used fuel for electricity generation. Its usage has been on decline in the US since its peak in 2007, but global coal use has continued to increase, primarily due to high demand in China, India, and Southeast Asian countries.
READ MOREThis comparison is misguided: the uncertainties around these values mean they are likely to overlap. The key insight is that they are all much, much safer than fossil fuels. Nuclear energy, for example, results in 99.9% fewer deaths than brown coal; 99.8% fewer than coal; 99.7% fewer than oil; and 97.6% fewer than gas.
