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.

The request

“Create a stacked bar graph for Cedar Foods annual energy use from 2023 to 2026, stacking grid electricity at 940, 880, 810 and 760 MWh, natural gas at 620, 590, 540 and 510 MWh, and on-site solar at 60, 110, 170 and 230 MWh.”

Then tryAdd purchased renewable energy as a segment.Change 2026 on-site solar to 260 MWh.

FAQ

Common questions

What does each segment show?

It shows the energy supplied by one source during the year.

Does lower energy use always mean lower emissions?

Usually it helps, but emissions also depend on the source and applicable emissions factors.

Why use MWh?

Megawatt-hours provide a common unit for comparing electricity and converted fuel energy.
