Renewable Energy Generation at the University of Kelaniya
Renewable Energy Generation at the University of Kelaniya
Human activities, particularly fossil fuel consumption, are major contributors to climate change due to greenhouse gas emissions. Fossil fuels, still widely used worldwide, release pollutants that accelerate global warming. Renewable energy sources like solar, wind, and hydropower, however, offer cleaner, sustainable alternatives. By shifting to these sources, we can reduce environmental harm, conserve non-renewable resources, and lessen risks from environmental disasters such as oil spills. The United Nations has highlighted the critical importance of clean energy in its Sustainable Development Goals (SDGs), with SDG-7 aiming for universal access to affordable and clean energy by 2030. Energy powers essential sectors like healthcare, education, and transportation, making SDG-7 foundational to achieving other sustainability goals. This goal is a driving force behind global efforts to transition towards renewable energy sources.
In Sri Lanka, the energy landscape currently depends on a combination of fossil fuels and renewable sources. The government has set ambitious targets, aiming for 70% renewable energy in electricity production by 2030 and achieving carbon neutrality by 2050. To support these goals, the Sri Lanka Sustainable Energy Authority (SLSEA) was established in 2007 to drive nationwide efforts in energy efficiency and sustainable resource management.
The University of Kelaniya aligns with these national objectives by incorporating sustainable practices and renewable energy initiatives within its all premises. As an academic institution, it not only contributes to sustainable energy use but also actively educates and engages students and faculty in research and innovation focused on clean energy. Through these efforts, the university plays a vital role in promoting sustainable development practices in line with both national targets and the global SDGs.
Ratio of renewable energy production divided by total energy usage per year
Ratio of renewable energy production divided by total energy usage per year
Usually, Sri Lanka receives nearly 10 hours of sunlight per day, and this calculation was used as 6 hours of average sunlight when considering rainy weather etc.
Annual renewable energy production = (11,150.75 + 580,350 + 1,825)
= 593,325.75 kWh
Annual total electricity usage = 4,539,236 kWh
The ratio of renewable energy production per year
= (593,325.75 kWh/4,539,236 kWh)*100
= 13.07 %
