Abstract
This study aimed at renewable energy utilization and environmental sustainability. The study focused on how consumption of renewable energy, capacity, and electricity access affect environmental responsibility, carbon absorption, and pollution control in sustainable development. Survey research design was employed. The study targeted small and medium enterprises (SMEs). The population size was 12,517. The sample size of the study was 373. A multi-stage sampling technique was adopted so that the sample was selected in stages. The reliability of the instrument was established using Cronbach's alpha test. Descriptive and inferential statistical techniques were employed in the research to analyze the data collected. Linear regression analysis was used to test hypotheses. Findings revealed that consumption of renewable energy significantly affects carbon sequestration and that renewable energy capacity has a significant effect on pollution control among SMEs. The study concluded that utilization of renewable energy can improve environmental sustainability among SMEs. The study recommended that SMEs need to place high priority on the uptake and utilization of renewable energy sources such as solar, wind, and biomass to enhance their environmental sustainability. It also recommended that SMEs should increase their investment in renewable energy infrastructure and capacity development to strengthen their ability to control pollution and manage waste efficiently.
