IEA: the annual new installed capacity of renewable energy in the world will reach 700gw in the next 30 yearsDate：2021-01-15 Hits：
Under the "sustainable development scenario", it is expected that the global energy system will achieve full net zero emission in 2070; while under the accelerated deployment of low-carbon power generation technology, the world will enter the "faster Innovation scenario", and will achieve full net zero emission in 2050.
The report points out that about 1 / 3 of the global greenhouse gas emissions come from the energy industry. Therefore, the energy industry is faced with arduous task of emission reduction, which is also the most important area of emission reduction for all countries. In order to continuously promote energy transformation and structural adjustment, the development of renewable energy should become a global priority.
According to the IEA calculation, in the "faster Innovation scenario", by 2050, the global electricity consumption will be 2.5 times of the current, which is equivalent to increasing the annual electricity generation of the United States every three years. If we want to meet the new power demand in the future, the average annual new installed capacity of renewable energy in the world needs to reach 700gw within 30 years, which is four times of the new installed capacity in 2019.
Timur Guel, director of IEA's energy technology policy department, also affirmed the role and contribution of renewable energy to global emission reduction. "In recent years, the renewable energy industry has developed rapidly, whether it is photovoltaic or wind power. With the declining cost of power generation, the industry has become more mature and the market scale has been expanding," he said
But Timur Guel also stressed that the transformation of the power system can only help the world achieve 30% of the net zero emission target. "Industry, construction and transportation are also big producers of carbon dioxide, accounting for more than half of the total carbon dioxide emissions of today's energy system. If no measures are taken, they will become the main "culprits" of carbon emissions in the future. "
In order to achieve the goal of net zero carbon emission as soon as possible, countries around the world need to focus on the existing equipment assets and infrastructure in the field of power and industry. Whether these devices can operate more cleanly and low-carbon will directly affect the realization of emission reduction targets. Data show that at present, the carbon dioxide emissions of steel, chemical and cement industries account for 7%, 4% and 7% of the total global emissions respectively.
"This is the part that has been ignored before. Based on the current feasible development path, we can reduce the impact of this part on the climate through renovation and upgrading, early decommissioning or extensive application of carbon capture, utilization and storage technology. " Timur Guel said, "at present, renovation and upgrading may be the most economical way. In the next 20-30 years, most countries will have the demand for maintenance of basic equipment. If the new emission reduction technology can be applied to the existing equipment at the right time, the global carbon dioxide emissions will be reduced by about 40%
The report also pointed out that whether it is for the power, heavy industry, transportation and construction fields, the realization of emission reduction goals ultimately depends on technological innovation and progress. At present, half of the emission reduction technologies are still in the laboratory stage and have not been commercialized. Therefore, governments need to formulate and issue effective policies to promote the application of new technologies in the early stage of the market, increase capital investment in research, development and pilot, encourage the market to participate in the innovation of emission reduction technologies, and constantly promote the development of clean energy industry.
The report predicts that after the global net zero emission and the successful construction of a safe and sustainable energy system, great changes will take place in the world energy system, from coal, oil and natural gas to electricity, hydrogen, synthetic fuels and bioenergy.
