The IEA, based in Paris, said in the World Energy Outlook 2018 report that energy demand will increase by more than a quarter between 2017 and 2040, assuming energy efficiency improves, while without these improvement requirements it has doubled, according to Reuters .
According to IEA estimates, global gas demand would increase by 1.6 percent per year by 2040 and would be 45 percent higher than today.
The estimates are based on the IEA's "New Policy Scenario" document that takes into account the legal regulations and emission reduction policies, as well as the fight against climate change, and also begins with the assumption of greater energy efficiency in fuel use, energy efficiency of buildings and other factors.
China, which is already the world's largest oil and coal importer, will soon become the largest importer of gas and the net imports will reach the EU level by 2040, according to the IEA.
According to Reuters estimates, China has pushed Japan out of the position of the world's largest natural gas importer based on data from the Chinese customs administration.
Although China is the third-largest natural gas user in the world, behind the United States and Russia, it has to bring about 40 percent of its needs, as domestic production can not "hasten" the demand.
Asian emerging economies will participate in global gas demand of about 50 percent, and their share in TPG imports by up to 60 percent by 2040, according to the IEA report.
Global demand for electricity will increase by 2.1 percent per year, mainly due to increased consumption in developing countries. By 2040, electricity will account for a quarter of the total energy consumption used by end-users, such as households and industry.
Coal and renewable energy sources will replace sites in the energy mix for electricity generation. It is estimated that the share of coal in this mix in 2040 will fall by a quarter of today by about 40 percent, while renewable energy from the current quarter will grow by more than 40 percent.
Carbon dioxide emissions associated with electricity production will continue to grow slowly but steadily up to 2040. CO2 emissions from 2017 levels, according to IEA forecasts, increased by 10 percent to 36 gigaton in 2040, mainly due to increased oil and gas consumption.
This is way "far from the steps", which according to the scientific knowledge needs to be taken to deal with climate change, according to the IEA report.
