The Answer

The line chart illustrates how the world’s renewable energy was generated over 20 years between 2000 and 2020, divided between three named energy sources and a fourth category denoting all other kinds of renewable energy. Units are measured in TWh. 

Overall, the amount of energy generated from all sources rose over the two decades for which data is available. Hydropower consistently generated by far the most; in 2000, it was approximately 2,600 TWh, rising steadily over each of the five-year intervals shown up to a peak of roughly 4,250TWh in 2020. 

At the beginning of the period shown, solar’s energy generation was at zero, with growth remaining flat in the decade to 2010; it then rose slightly until 2015. At that point, it began rising sharply to approximately 800TWh last year. Wind power, which was generating around 100TWh in 2000, generated only a modest increase in energy in the period to 2005, but then generated substantially more between 2005 and 2020 to a high of roughly 1450TWh in 2020. Other renewables were generating around 250TWh in 2000, increasing gradually throughout the period shown to a high of around 600TWh by 2020.
