Why the International Day of Clean Energy Matters

Renewable energy is produced from natural elements such as sunlight, wind, rain, tides, and geothermal heat. This type of energy reduces the environmental impact compared to traditional energy sources like coal and oil. Minimized greenhouse gas emissions and no need for extensive power infrastructures are some of its benefits.
So, in 2023, the United Nations assigned January 26 as the International Day of Clean Energy to highlight the environmental, economic, health, and societal impacts of our energy choices.
The day aims to spotlight the upfront cost of setting up renewable infrastructure, particularly for developing nations and remote areas.
Another challenge it wants to tackle is the need for more awareness about the benefits of adopting clean energy. The fossil fuel industry, backed by powerful political and economic forces, often hinders the progress of renewable sectors.
Moreover, communities reliant on polluting fossil fuels express concerns about financial instability and job losses during the equitable energy transition. People without clean energy access might also have trouble finding economic, educational, and healthcare opportunities.
Through this annual observance, we are called to advocate for education and accessibility of clean energy sources.
Data and Statistics
The International Renewable Energy Agency (IRENA) says renewable energy sources accounted for 29.1% of electricity generation in 2022.
The International Energy Agency (IEA) forecasted renewable energy to contribute over 42% of global power generation by 2028.
Moreover, in 2021, 675 million people lack access to reliable power sources, and 80% of them live in rural areas.
Sources of Clean Energy

- Solar energy comes from the sun's rays. It's converted into electricity using photovoltaic cells, commonly seen in solar panels. Solar power is renewable, abundant, and produces zero emissions during operation.
- Wind energy comes from converting the wind's kinetic energy into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water), or a generator can convert it into electricity.
- Hydropower comes from the energy of falling or fast-running water, which may be harnessed for practical purposes. Traditionally, a dam creates a reservoir of stored water released through a turbine to generate electricity.
- Geothermal energy is generated and stored on Earth. Geothermal power plants use steam from hot water reservoirs found a few miles below Earth's surface to generate electricity.
- Biomass energy results from organic material from plants and animals, including crops, waste wood, and trees. Burning biomass releases chemical energy as heat, generating electricity through a steam turbine. Biomass can also be converted into biogas or biofuel gas.
Brief Timeline of International Day of Clean Energy
The UN Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil, marks an important step towards global recognition of sustainable energy.
The intergovernmental organization, International Renewable Energy Agency (IRENA), is founded to promote renewable energy adoption and its sustainable use.
The UN launches the Sustainable Energy for All initiative, aiming to ensure universal access to modern energy services, double the global rate of improvement in energy efficiency, and double the share of renewable energy in the global energy mix by 2030.
The UN General Assembly proclaims 2021-2030 as the Decade of Sustainable Energy for All, reinforcing the importance of clean energy in achieving the Sustainable Development Goals.
The UN adopts the 2030 Agenda for Sustainable Development, which includes a dedicated goal (SDG 7) to ensure access to affordable, reliable, sustainable, and modern energy for all.
As part of his strategic agenda for the coming years, the UN Secretary-General calls for a global coalition for net-zero emissions by 2050.
The UN General Assembly passes A/RES/77/327, officially establishing the International Day of Clean Energy on January 26.
