The given diagram depicts the energy consumed from the different sources in quadrillion units during the time period of 1980 till 2030.
As can be seen from the diagram that since the 1980s, petrol and oil have been used much more as compared to the other sources of energy. In future also the consumption of energy from petrol and oil will be increasing only. The usage remaining around 40 quadrillion units.
Talking about coal and natural gas, the usage has remained around 20 quadrillion units. The natural gas usage will remain constant in near future, whereas the coal consumption will increase. Nuclear, solar/wind, hydropower source of energy has been remained low as compared to other sources. In near future amongst three sources of energy, the usage of nuclear energy will increase, whereas solar/wind will remain in between and hydropower will remain the least used.
From the figure, the usage of non-renewable energy sources had remained more since early time till the near future whereas the usage of renewable energy sources had remain less and will also remain less in coming time.
