Energy distribution in the context of "Grid (electricity)"

Energy policies are the government's strategies and decisions regarding the production, distribution, and consumption of energy within a specific jurisdiction. Energy is essential for the functioning of modern economies because they require energy for many sectors, such as industry, transport, agriculture, housing. The main components of energy policy include legislation, international treaties, energy subsidies and other public policy techniques.

The energy sector emits more greenhouse gas worldwide than any other sector. Therefore, energy policies are closely related to climate policies. These decisions affect how high the greenhouse gas emissions by that country are.

Energy management includes planning and operation of energy production and energy consumption units as well as energy distribution and storage. Energy management is performed via energy management systems (EMS), which are designed with hardware and software components to implement the tasks. Energy management can be classified into building energy management, grid-scale energy management (including grid energy storage), and marine energy management.

Energy management objectives are resource conservation, climate protection and cost savings, while the users have permanent access to the energy they need. It is connected closely to environmental management, production management, logistics and other established business functions. The VDI-Guideline 4602 released a definition which includes the economic dimension: "Energy management is the proactive, organized and systematic coordination of procurement, conversion, distribution and use of energy to meet the requirements, taking into account environmental and economic objectives". It is a systematic endeavor to optimize energy efficiency for specific political, economic, and environmental objectives through engineering and management techniques.
