How can you reduce your company’s energy bill?
Against a backdrop of rising energy prices and increased regulatory pressure, reducing energy costs is becoming a strategic lever for competitiveness, profitability and corporate image. In 2025, faced with market instability and societal expectations, what are the most effective strategies to adopt? Discover our analysis.
Reducing energy bills has become a strategic challenge
Energy context in 2025
Since 2022, electricity and gas prices have experienced exceptional volatility. This instability has been exacerbated by the war in Ukraine, the European energy transition and the new requirements of the Tertiary Decree in France. According to ADEME, energy management is now a priority for companies.

Companies: CSR and competitiveness
By reducing their energy consumption, companies can:
-
Reduce their operating costs,
-
Comply with regulatory requirements (e.g. CSRD and Décret Tertiaire),
-
Strengthen their CSR commitments,
-
Améliorer leur compétitivité sur le long terme.
Making the most of energy data for better performance management
In 2025, energy consumption data will become a strategic asset in its own right. Thanks to intelligent measurement technologies (IoT sensors, connected meters, supervision platforms), companies can monitor their usage in real time, detect drifts and adjust their strategy.
The implementation of an ISO 50001-compliant energy management system (EMS) enables us to structure a continuous improvement process, identify the most energy-intensive equipment and generate automatic alerts.
The most advanced companies even cross-reference this data with their management tools (ERP, CMMS, etc.) to fine-tune their operations (production, weather, occupancy, etc.).
In short, the intelligent use of data enables energy performance to be firmly anchored in the company’s overall strategy.
The best energy efficiency strategies in 2025
Carry out an in-depth energy audit
An energy audit is the first step in a structured approach. It enables us to identify energy-intensive items, identify potential energy savings and prioritize corrective actions.

Good to know: Carrying out a complete efficiency project prior to a solar project allows you to size the project to already optimized needs. This effectively reduces dependence on the grid and the “uncontrollable” portion of energy costs.
Optimize heating, ventilation and air conditioning (HVAC) systems
HVAC equipment can account for up to 50% of energy bills in commercial and industrial buildings. The key levers in 2025 :
-
Upgrade boilers or install heat pumps,
-
Install intelligent control systems,
-
Regularly maintain heating and ventilation systems,
-
Adapt temperature to occupancy periods.
Improve lighting efficiency
An obsolete lighting system can account for up to 25% of energy costs. Simple, effective solutions:
-
Replacement of luminaires with latest-generation LEDs,
-
Add presence or brightness detectors,
-
Intelligent space zoning,
-
Better use lighting at the end of the day or in low-traffic areas.
Adopt a collective energy-saving approach
Reducing consumption also involves people. To be effective, this approach must be based on employee involvement and cross-functional energy governance involving all company departments:
-
Train employees in eco-gestures,
-
Appoint one or more energy coordinators,
-
Communicate results to mobilize teams over the long term.
Effective governance also involves general management, HR, technical and purchasing departments. It creates a shared culture of energy efficiency and optimization.
Getting involved in self-generated energy
To reduce their energy bills over the long term and strengthen their autonomy, companies are turning to self-generation of energy. This strategy is based on the installation of appropriate local production and storage equipment:
-
Photovoltaic panels on roofs, parking lots or shaded areas,
-
Hybrid systems combining solar generation and batteries or thermal storage,
-
Heat pumps for heating and/or cooling.
This production allows us to better control costs, reduce transmission losses and improve our carbon footprint.
Adapting energy supply contracts
Too often overlooked, this strategy can generate up to 20% in immediate savings:
-
Regular review of supply contracts,
-
Informed choice between fixed and indexed offers,
-
Competitive bidding for suppliers.
Mobilizing financial aid
In France, there are a number of ways to reduce out-of-pocket expenses:
-
Energy Savings Certificates (CEE),
-
ADEME or regional subsidies,
-
Third-party financing, offered by operators such as GreenYellow.
