International Day of Clean Energy
26 January 2026 — Wind, sun and water – power for all! Let’s spin toward a cleaner future!
The International Day of Clean Energy is observed every year on 26 January, as established by the United Nations. The date marks the anniversary of the founding of the International Renewable Energy Agency (IRENA) in 2009. The day aims to encourage wider use of energy from the sun, wind and water, and to promote fair access to clean energy for everyone. It is also tied to efforts to reduce the emissions that change our climate. Events include conferences, school activities, exhibitions and meetings where new technologies and policies are discussed. Many people use the day to think about how they can save energy at home. The link to the sky is direct: sunlight and winds, which arise from the uneven heating of the atmosphere by the Sun, are core sources of clean power. Our star quietly powers both the sky and the Earth.
Flying across the sky: An ethereal, bluish-silver figure made of luminous dots and thin lines, like a constellation: a cheerful three-bladed wind turbine rotor drifting across the sky, carried by a single shimmering ray of light
