The Atacama Desert in northern Chile is one of the driest places on Earth. But beneath its clear skies and constant winds lies a resource that is reshaping the global energy map: the most intense solar radiation on the planet and a wind potential few places can match.
Chile aims to become the first developing country to achieve carbon neutrality by 2050, and its desert is the key.
A Natural Lab for Renewables
In the Antofagasta region, dozens of solar and wind farms stretch across a territory that once only held copper mines and salt flats. The combination of extremely high irradiation —over 3,000 hours of sunshine per year in wide areas— and steady winds has turned this Pacific strip into a testing ground for storage and clean generation technologies.
The Storage Challenge
Solar and wind intermittency requires large-scale storage. Chile leads projects in lithium batteries and 'power-to-X' to convert electricity into green hydrogen.
From Copper Mining to Sun Mining
Chile's economy, historically dependent on copper and saltpeter, is undergoing a quiet transition. The same mining companies that extract lithium for batteries now invest in solar farms to power their operations. The dual goal: cut energy costs and meet environmental standards demanded by international markets.
The bet is not just local. Green hydrogen produced in Atacama —using renewable electricity to split water into oxygen and hydrogen— could be exported to Japan, South Korea and Europe, which seek to decarbonize heavy industries. Several pilot projects are already underway, though commercial scale still faces cost and logistics hurdles.
The International Energy Agency estimates Chile could produce green hydrogen at under $2 per kilogram by 2030, competing with fossil fuels.
What Does This Mean for the World?
Chile's experience shows that renewables are not just an ecological alternative but a development strategy. For developing countries with high solar or wind potential, the Atacama example offers a roadmap: how to leap from fossil fuel dependence to a clean matrix, attracting investment and generating skilled jobs.
But the path is not without challenges. The environmental impact of solar panels and turbines —from land use to waste management— requires regulation. Moreover, transmitting energy from the desert to consumption centers demands gigantic high-voltage lines, whose construction faces social and bureaucratic opposition.
The Future on the Horizon
Chile is not alone in looking to the desert. Morocco, Australia, the United Arab Emirates and South Africa are exploring similar projects. But Chile's advantage lies in its stable institutions, openness to foreign investment, and a network of trade agreements that facilitate clean energy exports.
The global energy transition needs places like Atacama: where sun and wind are not a complementary resource but the foundation of a new economic model. The world watches, and the desert responds.
