About International Day of Clean Energy
The International Day of Clean Energy is a United Nations observance held on 26 January. It is intended to increase awareness and encourage action around an inclusive transition toward clean energy.
The observance can cover renewable energy, energy access, efficiency, finance, technology and policy, but those subjects should be explained with current evidence rather than reduced to a single technology or slogan.
Why International Day of Clean Energy matters
Energy systems affect development, health, climate, infrastructure and economic opportunity. The day creates a common point for discussing how countries can expand reliable energy services while reducing pollution and emissions.
Because technologies, costs and national energy mixes change quickly, evergreen history should be kept separate from current statistics, targets and market claims.
History of International Day of Clean Energy
The UN General Assembly established the International Day of Clean Energy through resolution A/RES/77/327.
The first observance was held on 26 January 2024; United Nations material from that date explicitly identifies it as the first International Day of Clean Energy.
The date 26 January was chosen because it is the founding date of the International Renewable Energy Agency (IRENA), which was established in 2009.
