Fossil fuel will not go anywhere. The future looks bright, without emissions and electric. But the recent report of the International energy agency offers reality check. The world still very strongly depends on oil and gas - and even from coal - in respect of continuous deliveries of energy. To the world where energy sources on all of 100 % renewed, some more decades, and even more need.

About it the publication in Oil price Irina Slav's author. She refers to report IEA entitled «Key world energy statistics - 2020». Utm content in it tendencies of manufacture and consumption of energy from the beginning from 1970 to 2018 are in detail considered.

And the data shows, writes Slav that we still strongly depend on oil and gas, despite all progress which occurs in the sphere of renewed energy sources. «Actually, the oil and gas share in world energy balance is so great that is doubtful that we will ever refuse fossil fuel».

Here are some calculations. In 1973 on crude oil 48, 2 % of final consumption of energy all over the world was necessary. Later 45 years and huge achievements in the field of renewed energy sources the share of crude oil in the general final consumption of energy fell to poor 8,6 percentage points to 40,8 %.

During the period with 1973 to 2018 the world offer of energy grew from 6089 million tons of oil equivalent to more 14 billion tons of oil equivalent as the world's population grew and became richer that led to growth of demand for energy.

Therefore it is no wonder that emissions grow, though "responsibility" distribution between three kinds of fossil fuel has changed. In 1973 oil was the largest source of emissions, making up 49, 9 % from total amount, on gas 14,4 % and on coal - 35,7 % were necessary. In 2018, possibly, thanks to energy efficiency and a growing share of gas in electric power manufacture, in particular, the oil share in the general emissions fell to 43, 1 %.

However, thus the coal share has grown by 44 %, and a gas share – by 21, 1 %. It means that we already know: fossil fuel is cheap, therefore it often prefer not only in regions which do not presume to invest to itself in wind and solar energy, but also in China, the world's largest investor in renewed energy sources, and also in the majority of other countries.

And though solar and wind energy become cheaper, their reliability remains a problem to which only recently have started to give proper attention in the form of a concentration not only on generating capacities, but also stored.

As to wind and solar generation impressing growth - not for 45 here is observed, and there are less than years. During the period from 2005 to 2018 manufacture of electric power by means of wind grew from 104 terawatts-hours to 1273 terawatts-hours. Solar energy manufacture has shown so impressing growth: from 4 TWh in 2005 to 554 TWh in 2018.

Being based on this data covering more of four decades, forecast IEA for next two decades also includes oil and gas and substantially them considers as within the limits of the so-called scenario of state policy, and the sustainable development scenario.

Actually, in both scenarios, oil and gas together still will make more energy, than renewed energy sources, even in 2040. Unique appreciable distinction consists that according to the scenario of sustainable development the oil share in a cumulative parity will be reduced approximately to 10 % during the period from 2030 to 2040.

The facts IEA provided, show that the world still very strongly depends on oil and gas in respect of continuous deliveries of energy. To the world of 100 % of renewed energy sources there are some more ten years...
