The line graph shows the installed capacity of renewable energy generation in gigawatts (GW) from 2000 to 2020. The data is broken down by energy type: solar, wind, hydro, and others. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The provided data illustrates the growth in installed renewable energy capacity by type between 2000 and 2020. Initially, hydropower was the dominant source, but the latter half of the period witnessed an explosive expansion in solar and wind power. At the beginning of the millennium, total renewable capacity stood at roughly 1,000 GW, with hydropower comprising the vast majority at around 700 GW. Other sources contributed about 250 GW, while solar and wind combined had a minimal presence, under 50 GW. Over the next decade, total capacity rose to approximately 1,400 GW. Hydropower saw a modest increase to about 800 GW, with other sources reaching 300 GW. Both solar and wind capacities grew, though they remained secondary to hydropower, with wind exceeding 100 GW by 2010. The most striking transformation occurred by 2020. Total capacity more than doubled from 2010 to over 2,500 GW. While hydropower and other sources continued to grow to around 900 GW and 400 GW respectively, solar and wind power experienced unprecedented surges. Solar capacity rocketed to over 700 GW, and wind power reached nearly 800 GW, eclipsing hydropower and becoming the leading renewable energy sources.
