STUDYING THE IMPACT ASSESSMENT OF HYBRID POWER SUPPLY IN SOUTH CAMPUS, THE POLYTECHNIC, IBADAN

This study conducts an environmental impact assessment of a hybrid power supply system at the South Campus of the Polytechnic Ibadan, comparing the effects of solar power generation and fossil fuel generators on noise pollution and air quality. The objectives were to evaluate the environmental impacts of both power sources, determine their long-term viability and health risks, and assess alignment with World Health Organization (WHO) guidelines. Field measurements were conducted at three locations in the campus: The Civil Engineering Department, the Engr. Aderemi Oseni Training Centre, and the South Campus Market. The air pollutants studied included formaldehyde (HCHO), total volatile organic compounds (TV0C), particulate matter (PM2.5 and PM10), carbon monoxide (CO), and carbon dioxide (CO2), Noise levels were also recorded, along with a questionnaire on community perceptions. Results highlighted severe air quality deterioration near fossil fuel generators, with high HCHO levels ranging up to 3.099 mg/m3 and elevated TVOC. PM, C0, and C02 levels, posing health risks like respiratory issues and cardiovascular diseases. Solar power systems, emitting no pollutants, were deemed healthier. Noise levels exceeded WHO guidelines near fossil fuel generators, reaching up to 95.7 dB (A), impacting learning and health with risks like hearing loss and stress. Solar systems operated silently, supporting a conducive learning environment. The questionnaire results support these findings, with a majority of respondents expressing concern over the health and environmental impacts of fossil fuel generators. There was strong support for transitioning to solar power, seen as a cleaner and quieter energy source. conclusion, the assessment underscores the substantial long-term health and safety risks psed by fossil fuel generators, including noise pollution and poor air quality. Conversely, solar power emerges as a safer, more sustainable energy source, aligning with WHO guidelines. The proposed hybrid power generation system, integrating solar power, is recommended to reduce reliance on fossil fuel generators, enhance environmental sustainability, and improve public health on campus. Prioritizing solar power adoption within the hybrid system can yield long-term economic benefits, reduce fuel and maintenance costs, and align with global sustainability goals.
