Figures rounded to two decimal places
Also need to have a list based on ease of extraction and energy required
Notable missing from top 20:
- Copper.
Carbon might replace copper for many electrical conduction applications, and in the right form has the potential to be an even more efficient conductor - see carbon nanotube
