Recently, the International Energy Agency (hereinafter referred to as IEA) has also changed its previous pessimistic expectations of renewable energy development and carbon emissions control. The release report indicates that renewable energy has occupied an important position in the field of electricity and will be further increased in the future.
According to the World Energy Outlook 2015 report released by the IEA, nearly half of the world's new power plants in 2014 were generated from renewable energy sources. IEA believes that the statistical result is "a clear sign of the global energy transformation". Renewable energy generation is "no longer just a small crowd in the field of electricity, and is now becoming a mainstream energy".
IEA also expects that the global investment in power generation will be as high as 60% into renewable energy from 2015 to 2040, with China, the EU, the United States and India leading the leading investment countries. In addition, investment in the field of energy conservation will also receive further attention. Statistics from IEA show that in 2014, a large number of energy-saving measures were adopted to help countries around the world save about 1/3 of energy use.
The 2015 World Energy Outlook report also predicts that the role of coal in the global energy market will not be as important as the impact of a substantial increase in the use of renewable energy. The IEA pointed out that coal had previously occupied an important position in the global energy structure and its share of total energy use had risen. For example, coal accounted for 23% of the total energy use in the world in 2000, and the proportion rose to 29% by 2014.
Recently, with the active consumption of major coal consuming countries to reduce the use of coal, this upward trend has reversed. According to IEA's data, the share of coal in global energy use will drop to 15% in 2040.
However, the IEA also pointed out that although the use of coal on the whole showed a downward trend, but the global emissions reduction can not be taken lightly.
From a national perspective, India is expected to become a major energy consuming country in the future. In 2040, India will not only become a major coal consuming country in the world, but will also be one of the major oil demand drivers. Among them, the amount of coal used in India and Southeast Asian countries will increase to 3 times by 2040. In addition, India is expected to become the second largest oil importer in the world in 2035.
But at the same time, renewable energy power generation will grow by leaps and bounds as compared with the reduction of coal. IEA statistics show that in 2014, renewable energy has become the second largest power source in the world after coal. It is expected that by 2030, renewable energy will surpass coal-fired power generation and become the largest source of electricity in the world, and by 2040, renewable energy will account for more than half of all new generation capacity.
Among them, in 2040, 5 of Europe will come from renewable energy, China and Japan are 3, the United States and India will be more than 25%, and India will cover 20% of the world's solar power. In contrast, coal-fired power will account for 30% of the electricity sector by 2040, and sub-critical power plants with low power efficiency will be reduced by 45%.
Another environmental group said that the global renewable energy technology breakthroughs far faster than expected, renewable energy has not yet fully realized the full potential. The group optimistically estimates that with the support of governments around the world, 100% of the world's electricity will come from renewable sources by 2050.
However, while the development of renewable energy slowed down the expected rate of increased carbon emissions, the IEA warned that global warming would be expected to reach 2.7 degrees Celsius, so the world still needs to boost its emissions.
