A report from the British center Ember, in partnership with the International Renewable Energy Agency, reveals that sustainable energies — especially solar and wind — have surpassed 40% of global electricity generation, even in the face of economic challenges and the pressure of cheap oil.

Sustainable energies are transforming the global electricity matrix. A recent report prepared by the British center Ember, based on data from the International Renewable Energy Agency (IRENA), shows that clean sources now account for 41% of global electricity generation. This historic milestone reflects the maturation of the sector and the consolidation of the energy transition, mainly driven by the low cost of installation and operation of solar and wind technologies.

Despite an international context of uncertainty, the movement towards renewable energies remains strong. Economic instability and variations in global trade could, in theory, discourage investments, but the efficiency of new technologies has been overcoming financial and political barriers.

Solar and Wind Stand Out in Global Growth

According to the study, solar energy led the expansion in 2024, with an average growth of 29% in global installed capacity. Meanwhile, wind energy showed an increase of 7.9% during the same period. In contrast, electricity generation based on fossil fuels recorded a modest increase of only 1.4%.

This leap is largely due to the popularization of distributed microgeneration, primarily from solar photovoltaic energy. More and more households and small businesses are installing solar panels, which helps democratize access to clean energy and reduce electricity costs.

The advancement of sustainable energies is also directly linked to a significant drop in equipment prices and increased efficiency of generation systems. In many countries, producing energy from the sun or wind is already cheaper than relying on fossil fuels.

This reduction in costs has encouraged the expansion of large solar plants and wind farms, which together represent a safer and more predictable alternative in the face of fluctuations in the oil market. However, it is important to highlight that the rapid growth of these sources requires investments in electrical infrastructure, such as transmission lines and intelligent management systems to balance energy supply and demand.

Challenges and Perspectives Ahead of COP30

On the eve of COP30, the numbers released reinforce that the global energy transition cannot be delayed. Even with the forecast of oil overproduction in the United States, which tends to put downward pressure on prices, the renewable energy sector demonstrates resilience and increasing competitiveness.

Amid economic and geopolitical uncertainties, the advancement of sustainable energies stands as a concrete response to the climate crisis. The world seems, at last, to be moving more consistently towards a cleaner, more efficient, and accessible energy model for all.
