Definition
Energy Management refers to the science and practice of optimizing energy productivity to achieve the most cost-effective, efficient, and environmentally friendly energy systems for particular applications. It encompasses the planning and operation of energy production and energy consumption units. The discipline gained significant momentum in the 1970s due to the oil embargo, which highlighted the need for effective energy management strategies.
Examples
- Energy Auditing: Conducting assessments to understand energy use patterns and identify opportunities for energy-efficiency improvements in buildings and industrial processes.
- Renewable Energy Integration: Implementing solar panels, wind turbines, and other renewable energy sources to reduce reliance on non-renewable resources and minimize carbon footprints.
- Smart Grid Technology: Utilizing advanced metering infrastructure and automated control systems to optimize the distribution of electricity and improve grid reliability.
- Demand Response Programs: Adjusting or shifting energy consumption during peak demand periods to balance supply and demand and reduce energy costs.
