Energy management is the best solution for direct and immediate reduction of energy consumption. For the last few decades we have been exploring various alternatives to conventional sources of energy like solar, wind and biomass energy. However, due attention must also be given to best utilization of energy, improvement in energy efficiencies and optimum management of energy resources. Infact, energy management deals with already existing sources and actual consumption. It includes planning and operation of energy-related production and consumption units.
The main objectives of energy management are resource conservation, climate protection and cost savings. The central task of energy management is to reduce costs for the provision of energy in buildings and facilities without compromising work processes.
The simplest way to introduce energy management is the effective use of energy to maximize profit by minimizing costs. Energy management could save up to 70% of the energy consumption in a typical building or plant.

The typical energy saving for any plant or building, using basic energy management principles, could be 10-15% of the total consumption. This percentage may rose to 25-35% by a medium scale energy management program (1 – 3 year). For achieving higher degree of savings, a long-term energy management program, spread over a period of three years or more, is required which will involve a certain capital investment. The major elements of an energy management program are:
- Set your goal: how much energy reduction do you want to achieve
- Know your numbers: how much do you consume
- Define major consumption units and try to reduce consumption
- Continuous review and management
Energy Savings Tips for Industries
- Avoid extra-load in peak time. It is way more costly.
- Turn off machines during shut downs, inspections, maintenance and when not in use.
- Regular and efficient maintenance of machines and motors prevents extra loads and saves 15 % of extra consumption and prevents break downs as well.
- Attend air and steam leakages. These leakages are extra load on boilers, compressors etc.
- Replacement of incandescent lamps with compact fluorescent lights (CFLs) or LEDs can save significant amount of energy.
Our case study for energy management program was developed and implemented in textile industry which is second highest industrial energy consumer in Egypt. The program, involving minimum investment, was implemented over a period of one year and proved to be a major success. Direct energy savings were approximately one-fourth of the total consumption. More than one million Egyptian pounds were saved from direct costs, in addition to considerable indirect savings.
Energy management is the process of monitoring, controlling, and conserving energy in a building or an industry. Energy management is the key to saving energy in your organization. Energy management is an important energy resource that can help meet future energy needs while the nation concurrently develops new and low-carbon energy sources
