The amount of renewable energy being used worldwide varies over time and by specific location. According to the International Renewable Energy Agency (IRENA), in 2019, renewable energy sources (excluding large hydro) provided about 26.5% of the world’s total final energy consumption. This includes energy from sources such as solar, wind, geothermal, and bioenergy. Large hydroelectric dams, which are also considered a renewable energy source, provided an additional 6.4% of the world’s total final energy consumption in 2019.
The countries that use the most renewable energy vary depending on the metric being used. Here are some examples:
- In terms of the percentage of total final energy consumption that comes from renewable sources (excluding large hydro), the top countries in 2019 were: Sweden (54.5%), Costa Rica (99%), Latvia (47%), and Uruguay (95.5%).
- In terms of the absolute amount of renewable energy consumption, the top countries in 2019 were: China, the United States, India, Brazil, and Russia. These countries have large populations and high levels of energy consumption overall, so it’s not surprising that they would also be among the top users of renewable energy.
- In terms of the percentage of electricity generated from renewable sources, the top countries in 2019 were: Costa Rica (99%), Iceland (100%), Norway (98%), and Uruguay (96%).
It’s worth noting that these rankings can change over time as countries work to increase their use of renewable energy and as the overall global mix of energy sources shifts.
It’s important to note that the percentage of renewable energy used can vary significantly from one country to another. Some countries, such as Sweden and Costa Rica, get a significant portion of their energy from renewable sources, while others rely more heavily on fossil fuels. Many countries are working to increase their use of renewable energy as a way to reduce their greenhouse gas emissions and combat climate change.
