Carbon emissions are causing the Earth to heat up, driving extreme weather and climate change. The most visible consequence is rising sea levels, caused by the buildup of greenhouse gases that trap heat in the atmosphere.
Beyond greenhouse gases, carbon emissions also stem from fossil-fuel power plant, especifically those fueled by coal.
Environmentally friendly renewable energy offers an alternative for reducing carbon footprints. Solar power plants (PLTS) are one such solution. Just how significant is the role of solar power in reducing carbon footprints?
How do solar power plants reduce carbon footprints?
Solar power plants reduce carbon footprints by replacing fossil fuel sources with clean energy derived from sunlight.
The process begins by capturing sunlight via solar panels and converting that solar energy into electricity. The generated electricity is then routed through an inverter, making it usable for homes and buildings.
Why do fossil fuel sources generate a carbon footprint?
Fossil fuels contain solid organic carbon derived from the remains of living organisms from millions of years ago. When these fuels are burned, the carbon oxidizes, releasing massive amounts of carbon dioxide into the atmosphere.
The average carbon footprint in Indonesia is 2.18 tons of CO2e per person annually. This figure is well below the global average of 4 tons of CO2e per person per year.
The industrial sector is a major contributor to carbon footprints due to its heavy reliance on fossil fuels and 24-hour operational schedules. The energy industry is the largest source of emissions, as energy generation involves combustion processes.
Solar power plants can reduce carbon emissions by 1 ton per year. Consequently, efforts to lower carbon emissions continue through various mitigation strategies—one of which is transitioning from fossil fuels to renewable energy.
Indonesia’s geographical location makes it ideal for harnessing solar energy. Straddling the equator, the country enjoys excellent solar exposure.
For every 1 kWp of solar power capacity installed, emissions can be reduced by 1 ton of CO2 per year. Calculations show that a solar power plant (PLTS) with a 1 MW (Megawatt) capacity can reduce CO2 emissions by 1,000 tons annually. The "carbon payback period", the time required to generate energy equivalent to the carbon footprint of the panels' production—is relatively short, ranging from 0.4 to 1.4 years.
Based on carbon trading data in Indonesia for 2023–2025, solar power systems can reduce electricity bills by up to 30%, or cut costs by as much as 65% relative to the power generated.
For instance, PT KAI (Indonesian Railways) managed to reduce operational costs by IDR 2.5 billion per year and cut carbon emissions by 1,400 tons of CO2 annually.
Long-term environmental impact of solar power
Beyond business benefits, solar power systems positively impact the environment by reducing carbon emissions and improving air quality. Solar energy is an abundant resource that generates no direct emissions.
Carbon emissions drop drastically as the shift is made from conventional power plants to solar energy systems.
Solar power fosters energy independence, as electricity can be stored in batteries. You can maintain operations during grid outages, thus eliminating concerns about scheduled rolling blackouts, therefore, ensuring business continuity.
However, solar power implementation is location-dependent. Installations require space, often occupying significant areas; consequently, unused land is frequently considered as a potential site for these systems.
Furthermore, solar power operations involve the use of hazardous chemicals. Solar panels contain silicon, cadmium, and selenium as primary materials. Excessive use of hazardous chemicals can contaminate the surrounding soil and water.
