In 2010, renewable sources of energy (mostly hydroelectric) produced 55.2 quads, or 10.5% of all the primary energy used on the planet.
The Department of Energy’s Energy Information Administration expects production of renewable energy to almost double by 2030, to 100.6 quads. At which point it will represent 13.9% of their projected total for that year (721.5 quads).
If energy consumption is closer to my projection of 963 quads, that same 100 renewable quads would be exactly the same percentage of the total as it is today…
