According to the IEA, if leaders take appropriate measures, especially by taxing carbon, solar energy will play a major role in the energy transition.
The International Atomic Energy Agency (IAE) published a report on Thursday, ("Solar Energy Perspectives"), that the sun will be able to provide a third of the world energy by 2060 in all its forms including (photovoltaic, thermal ovens ...).
"In 90 minutes, the Earth receives enough sunlight to meet its energy needs for one year," said Cedric Philibert, author of the report. But if this energy is abundant, its use is still only a small fraction of global energy mix, he noted.
This renewable energy can play a key role in the de-carbonization of the global economy, the IEA considers it necessary that the leaders adopt measures: aid deployment, subsidies to R & D, especially establishing a price carbon to facilitate the energy transition.
Interviewed by Bloomberg, Paolo Frankl, head of the renewable energy branch of the IEA said that "the strength of the sun is the incredible variety and flexibility of its applications, from small to large scale."
The agency shall include in its assessments of demographic change: it is estimated that by 2050, about 7 billion people, or 80% of the world's population will be living near the Equator (compared to 2 billion in the colder zones), consequently in the sunniest spots.
