Abstract
The concerted efforts of keeping up with the environment and mitigating the consequences of climate change should focus more towards reducing carbon oxides and other greenhouse gases emissions within stipulated regulations. One of the ways to achieve this is through adoption of sustainable practices within industries and organisations by encouraging more of energy saving practices and reduction of carbon footprint within all production, commercial and service related functions. Nigeria, an emerging economy nation, is identified with higher emission of greenhouse gases due to downstream gas flaring combined with rapid industrialisation, urbanisation and commercialisation activities. This research paper examines the potential impacts of energy saving within Nigerian telecommunications industry, and highlights how the cell sites base stations within the industry have great challenges and threats towards the climate change from the amount of energy generated and used within the system. The paper conducts a literature study on general energy overview, usage, impacts and concepts towards the benefits of energy saving practices. The overview, concepts and benefits of energy savings and renewable energy technology were also reviewed. Further investigations within the concept of energy saving towards using sustainable methods for addressing the climate change issues was also carried out. The research used a sustainability ranking procedure with both economic and environmental analysis to conduct a sustainability assessment on some identified renewable energy technologies such as wind, solar, geothermal. The result of the analysis of the research was able to come up with about €16.4B of potential energy savings cost within the fifteen years of operation if the recommended alternative energy could be used. This sustainability assessment had been conducted towards providing recommendations for more sustainable, suitable, alternative and affordable strategies for replacing or complementing conventional methods of powering telecoms industries in future.
