Energy use stacked bar graph

This stacked bar graph shows Cedar Foods' annual energy use by grid electricity, natural gas and on-site solar. It makes two changes visible at once: total energy demand and the sources that supply it. In this example, conventional sources decline while solar grows, but the chart alone does not calculate emissions or prove efficiency gains. For a sustainability report, document the metering boundary, units and treatment of purchased renewable energy. Use a companion emissions chart when the goal is to report carbon impact, because the emissions intensity of each energy source can differ substantially. It gives teams a concrete starting point for reviewing assumptions, data quality and next steps together.
