Where does our energy come from, and how has this mix changed over the last 100 years?
These charts from Truman Du examine the complex relationship between energy production, consumption, and related carbon emissions using information from Our World in Data.
The World’s Energy Mix (1900-2021)
In the last 10 years, total global energy consumption has risen nearly 15%. Before that, between 2000 and 2010, it increased by nearly 25%.
And despite frequent headlines about green initiatives over the last few years, fossil fuels continue to account for the majority of total energy consumption.
In 2021, 77% of global energy was sourced from coal, oil, and gas.
Even so, renewable energy sources like wind, solar, and hydro have gained traction since the year 2000. Hydropower was the biggest renewable energy source in 2021, accounting for 6.3% of total energy consumed.
A Fossil Fuel Heavy Mix
Taking a closer look at the breakdown of energy by source, another strong (if slightly counterintuitive) trend appears to be holding its own.
Coal has remained a key source of the world’s energy consumption since 1900. Despite its relative share decreasing over time, as of 2021, coal remains the second biggest energy source, accounting for 25% of the world’s energy needs. All figures below are in TWh (terrawatt-hours).
|Global Energy Consumption||1900||1950||2000||2021||2021|
|Solar||-||-||3 TWh||94 TWh||2,702 TWh|
|Wind||-||-||93 TWh||962 TWh||4,872 TWh|
|Nuclear||-||-||7,323 TWh||7,374 TWh||7,031 (Read more...)|
