Our methodology
Given the nature of dominant innovations in the 21st century, most of our inventions are essentially technologies. To select the most important inventions of the 21st century, we have identified inventions on the basis of their impact. The ranking of these inventions is done based on the following indicators: social impact, economic impact, and environmental impact.
Each indicator was assigned a score from 0 to 20. The total score, out of 60, was determined by adding up the scores for all indicators. Hence, higher scores indicate higher rankings. The score for each indicator has been derived from extensive research on the internet and thus, in essence, is calculated based on consensus. The list is presented in ascending order.
Note: Some of the technology we have discussed is older (in terms of proof of concept) than the 21st century itself. However, such technologies like Hydrogen Fuel Cells only became commercially viable in the 21st century, which is why we have them in the list.
