Energy Efficiency
Energy efficiency means using less energy to deliver the same service or output. In the context of carbon management, energy efficiency is the fastest, lowest-cost decarbonization lever because every unit of energy saved reduces both operating costs and greenhouse gas emissions simultaneously.
Energy efficiency improvements reduce the energy input required for a given output — cooling a building, running a production line, lighting a warehouse, or powering IT infrastructure. Unlike renewable energy procurement, which changes the source of energy, efficiency reduces the total amount needed.
Common efficiency measures include LED lighting (40–70% reduction in lighting energy), HVAC optimization (10–30% savings through scheduling, setpoint adjustment, and equipment upgrades), building envelope improvements (insulation, windows, air sealing), compressed air leak repair (20–50% of compressed air is lost to leaks in typical facilities), motor and drive upgrades (VFDs on pumps and fans), and process heat recovery.
The economics are compelling: efficiency projects often have the highest ROI of any decarbonization investment, with payback periods of 1–5 years and internal rates of return of 15–40%. Government incentives further improve returns — utility rebates, IRA Section 179D deductions, and state-level programs can cover 20–50% of project costs.
Identifying efficiency opportunities requires granular energy data. Gravity's Insights module analyzes utility consumption patterns to surface anomalies, benchmarking outliers, and specific savings opportunities — turning operational data into funded, measurable projects.

Energy Management
Energy management is the systematic monitoring, control, and optimization of energy consumption in an organization to reduce costs, improve efficiency, and lower carbon emissions. It encompasses utility bill tracking, real-time meter monitoring, anomaly detection, efficiency project planning, and incentive capture.
Decarbonization
Decarbonization is the process of reducing greenhouse gas emissions across an organization's operations and value chain through energy efficiency improvements, fuel switching, renewable energy procurement, process changes, supply chain engagement, and technology adoption. It is the operational work that turns reduction targets into real emission cuts.
Utility Bill Management
Utility bill management is the process of systematically collecting, validating, and analyzing utility bills — electricity, natural gas, water, steam, and waste — across an organization's facilities to ensure billing accuracy, track consumption trends, identify anomalies, and feed data into carbon accounting and energy management workflows.
Scope 2 Emissions
Scope 2 emissions are indirect greenhouse gas emissions from the generation of purchased electricity, steam, heating, and cooling consumed by an organization. They are called 'indirect' because the emissions physically occur at the power plant or utility, not at the reporting company's facilities.
