IEA predicts that the capacity of renewable sources will have a record increase of 8%, with solar energy the main driver of such expansion.

As estimated by the IEA (International Energy Agency), the capacity of renewable energy sources across the planet should reach, in 2022, the unprecedented expansion of 8% compared to last year, in order to exceed, for the first time, the mark of 300 GW produced in a single year. In this sense, the main responsible for the growth of renewable sources will be solar energy.

This can be explained by the fact that solar energy will be responsible for about 60% of the total increase in capacity from renewable sources, reaching its best performance in all history, given the generation of 190 GW of energy and the increase of 25% to 2021. According to IEA Executive Director Faith Birol, this sector is becoming the new leader in the world's electricity markets. For him, if governments and investors expand their clean energy policies, in association with the scenario of sustainable development, the expansion of solar energy and wind power can be even greater, in addition to being a great help in overcoming the global climate challenge.

According to the IEA, the record growth of renewable sources can be explained by the accelerated energy transition policies practiced by the European Union, China and the United States, in addition to the natural expansion factor of renewables.

Government support and subsidy are key factors in enabling the expansion of clean energy

In China, for example, the local government has invested in financial aid for projects that promote clean energy, in order to end carbon releases in their municipalities. In addition, the IEA stated that, after China, the European Union was the second largest market in terms of expanding capacity from renewable sources, with the region having surpassed the all-time record for the first time in 2011.

The agency also highlighted that photovoltaic solar energy alone accounted for most of the growth last year due to the celerity of projects in Spain, France, Poland and Germany, having been driven by a combination of auctions led by the government and distributed photovoltaic solar incentives.

In the United States, in turn, the expansion of renewable sources, especially solar energy, is mainly due to investment tax credits, available until 2023/2024. As the agency explains, such credits have made possible a relatively stable political environment, although the existence of logistical and chain challenges has interrupted a much faster growth.

It is also worth noting that, in addition to the places mentioned, Brazil plays an important role in the production of solar energy, since it was included in the group of the 20 leading countries in installed capacity of solar energy in the world, with a production equivalent to approximately six thousand megawatts.

IEA believes that, next year, the trend is for the stabilization of the growth of renewable energy sources

As for perpetuating growth for years to come, the IEA said that unless new and more effective policies are adopted in 2023, increases in global renewable energy capacity are likely to remain stable compared to 2022.

However, even in the face of the stagnation scenario, the agency believes that solar energy must be the only source which will be expanded in order to reach the 200 GW barrier. At the same time, the growth of wind power and bioenergy is expected to remain stable, and electric power will be reduced by 40%.
