Just because we source more of our energy from sources other than fossil fuels, does not mean we bring down our consumption of them

A World Bank data set shows that the world has gone from 94 % of all energy being sourced from fossil fuels in 1960, to 80 % in 2015, in the world as a whole. 

While that is great, the world consumed 40,900 TerraWatt Hours (TWh) equivalent of fossil fuels in 1965. This shot up to 131,100 TWh in 2015, an increase of more than three times. So what we have to really look for is countries that reduced their consumption of fossil fuels.
  • Sweden sourced just 27 % of its energy needs from fossil fuels in 2015 compared to 75 % in 1960 (it also reduced its fossil fuel consumption by 20 % from 1965 to 2015).
  • The Czech Republic sourced 76 % of its electricity from fossil fuels in 2015 (it also reduced its fossil fuel consumption by 19 % from 1965 to 2015).
  • Denmark sourced 66 % of its energy needs from fossil fuels in 2015 compared to 100 % in 1960 (what is commendable is that it also reduced its fossil fuel consumption by 11 % from 1965 to 2015). 
  • Germany sourced 80 % of its energy needs from fossil fuels in 2015, compared with 99 % in 1960 (but it increased its fossil fuel consumption by 2 % from 1965 to 2015).
  • France went from sourcing 96 % of its energy needs from fossil fuels in 1960 to 47 % in 2015 (but it also increased its fossil fuel consumption by 21 % from 1965 to 2015).
  • Estonia sourced just 12 % of its energy from fossil fuels in 2015 !
  • Belgium sourced 76 % of its energy needs from fossil fuels in 2015 compared to 100 % in 1960 (but in another dataset from 1965 to 2015, it increased its fossil fuel consumption by 25 % in that period). 
  • Switzerland sourced half its energy needs from fossil fuels in 2015 compared with 75 % in 1960 (but it increased its fossil fuel consumption by 44 % between 1965 and 2015).
  • The US sourced 96 % of its energy needs from fossil fuels in 1960 compared to 83 % in 2015 (however it increased its use of fossil fuels by 60 % between 1965 and 2015).
  • Finland sourced 40 % of its energy from fossil fuels in 2015 compared with 45 % in 1960 (however it nearly doubled its use of fossil fuels from 1965 to 2015).
  • Austria sourced 66 % of its energy from fossil fuels in 2015, compared to 84 % in 1960 (however it nearly doubled its use of fossil fuels from 1965 to 2015).
  • Even bad boy Canada (for its shale oil !) has gone to sourcing 74 % of its energy from fossil fuels in 2015, compared to 83 % in 1960 (sadly, it increased its use of fossil fuels by nearly 2.5 times from 1965 to 2015).
  • Chile sourced 73 % of its electricity from fossil fuels in 2015 (but its use of fossil fuels went up nearly 4 times from 1965 to 2015).
Some countries went the other way though - they sourced more of their energy needs from fossil fuels in recent years than they did decades ago :
  • India went from 35 % of its energy needs sourced from fossil fuels in 1971 to 74 % in 2014.
  • China went from 56 % of its energy needs sourced from fossil fuels in 1971 to 88 % in 2014.
