What will the average growth rate be, of total renewable energy produced worldwide, over the 2020 to 2022 period?

According to OECD estimates, over 1.881M of tonnes of oil equivalent (toe) of renewable energy was produced in 2016. Renewable energy production saw impressive growth over the 70's during which total renewable energy produced grew at an average rate of 2.4%. This slowed down in the 90's to around 1.46%, but has picked up recently. Over the 2014 to 2018 period, more renewable energy capacity has been installed than new fossil fuel and nuclear capacity combined (REN 21, 2019). Of the new renewable energy capacity installed in 2018, 55 percent (about 100 GW) was solar PV; wind power had 28 percent, and hydropower 11 percent (ibid.). This suggests that the future of the world depends on solar continuing to boom.

Over the 2014 to 2016 period, total renewable energy produced grew at an impressible 3.47% year-over-year, on average.

What will the average growth rate be, of total renewable energy produced worldwide over the 2020 to 2022 period?


This question resolves as the geometric mean of year-over-year growth in total renewable energy produced worldwide in % for the periods 2019 to 2020, 2020 to 2021, and 2021 to 2022, as calculated from OECD estimates.

The geometric mean is used, as opposed to the more common arithmetic mean, because this is appropriate for growth that multiplies over time.

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
