The study by experts in solar energy predicts that capacity in the world's electricity sector will increase threefold by 2050.

All of this increase in electricity and solar energy, and more, will be achieved through renewable energy, which will grow at an accelerated pace until 2050, according to experts at the Starcraft. The report predicts growth in solar power generation of the order of 12% per year on average, while wind power generation will increase by more than 8% per year. Electricity, on the other hand, will grow more slowly when compared to other sources, at a predicted average of 1,5% per year.

Emerging markets beyond solar

In addition to solar energy and electricity, Natural Gas, a source widely used in countries such as the USA and Russia, is expected to show growth of 39,47% in its installed capacity in the same period, rising from 1,9 TW to 2,65 TW. However, the IEA estimates that the biggest growth will be carried out by the generation of photovoltaic solar energy, which should reach a worldwide installed capacity of 3,142 TW by 2035, say the Experts.

The volume will be greater than any other current source, renewable or not, including wind, hydro, natural gas and coal. Based on the current trend, the experts' study states that alternative energy sources will continue to dominate the growth of world electricity generation, accounting for 2/3 of the 8,5 TW of new capacity that should be installed by 2040.

Concentrated and controlled growth

This growth in solar energy and electricity will not be homogeneous, but will be concentrated in countries such as China and the European Union (EU), which will account for up to 80% of their electrical matrices from clean energy sources, while in the rest of the world they will account for less. half of the generation.

Investment in renewables including solar and wind power, which last year was $390 billion, is expected to remain at around $440 billion through 2030, suggests the IEA, below the $650 billion needed to meet the industry's sustainability targets. world electric.
