Appraising the Cost and Heat Emission Implications of Residential Energy Efficient Lighting in Benin City, Edo State

摘要

Both Climate change and energy poverty will impact on the collective health, security and economy of Nigeria and make it impossible for the country to attain the MDG Goals. To ensure improved access to energy, while at the same time safeguarding the ecosystem will require energy efficiency initiatives targeted at large-scale implementation of efficient lighting technologies. Compact Fluorescent Lamps (CFLs) are a direct substitute for incandescent light bulbs which is widely used in Nigeria. The paper aims to evaluate the energy and cost savings using compact fluorescent lamps substitute for incandescent light bulbs University campus. The retrofitting exercise lasted for one month between 4pm to 7pm daily. No CFL bulb was given to occupant for personal installation, to ensure that all the points were installed to avert possible reinstallation with incandescent bulbs. Results of post audit evaluation showed that peak loads for the sampled quarters dropped reasonably while energy consumption bills also dropped. In the Professorial quarter money saved is N62,954.58 per month, in A quarter 86% of energy was saved while N224,109.46 money was saved in one month. In B quarter N333,777.45 energy consumption cost was saved in one month. To ensure that the benefits of CFLs are sustained, the study suggests the need for awareness and adequate sensitization of the public on the environmental and economic importance of CFLs through implementation of policies and measures to overcome communication barriers.
