Energy demand management is often referred to also as demand side management (DSM). Energy demand management usually implies actions that influence the quantity of energy consumed by users. It can also include actions targeting reduction of peak demand during periods when energy supply systems are constrained. Peak demand management does not necessarily decrease total energy consumption but could be expected to reduce the need for investments in networks and/or power plants. Itaipu Dam is a hydroelectric generating station Electricity generation is the first process in the delivery of electricity to consumers. ...

The term DSM was coined in the 1970's when the 1973 energy crisis and 1979 energy crisis made it clear that some of the most convenient fossil energy reserves, such as crude oil, are approaching exhaustion (see article on Hubbert peak hypothesis). (Redirected from 1973 energy crisis) United States, drivers of vehicles with odd numbered license plates were allowed to purchase gasoline only on odd-numbered days of the month, while drivers with even-numbers were limited to even-numbered days. ... The 1979 (or second) energy crisis occurred in the wake of the Iranian Revolution. ... The Hubbert peak theory, also known as peak oil, is an influential theory concerning the long-term rate of conventional oil and other fossil fuels production and depletion. ...

How it works

Ideally, the energy use would be optimised by supply and demand price arbitration in the market. Various market failure mechanisms rule out an ideal result. One of the market failures is that suppliers' costs do not include all damages and risks of their activities. External costs are incurred by others directly or by damage to the environment. Theoretically the best approach would be to add external costs to the direct costs of the supplier as a tax (internalisation of external costs. Another possibility (referred to as the second-best approach in theory of taxation) is to intervene on the demand side by some kind of rebate. The supply and demand model describes how prices vary as a result of a balance between product availability at each price (supply) and the desires of those with purchasing power at each price (demand). ... In economics, a market failure is a situation in which markets do not efficiently organize production or allocate goods and services to consumers. ...

In economics external cost refers to a negative side-effect of an economic transaction, an act of exchange, consumption, or production. ... Rebates, also known as mail-in rebates, are primarily used as incentives or supplements to product sales. ...

Energy demand management activities should bring the demand and supply closer to a perceived optimum.

Governments of many countries mandated performance of various programmes for demand management after the 1973 energy crisis. An early example is the National Energy Conservation Policy Act of 1978 in the US, preceded by similar actions in California and Wisconsin in 1975. (Redirected from 1973 energy crisis) United States, drivers of vehicles with odd numbered license plates were allowed to purchase gasoline only on odd-numbered days of the month, while drivers with even-numbers were limited to even-numbered days. ... 1978 was a common year starting on Sunday (the link is to a full 1978 calendar). ...

Logical foundations

Demand for any commodity can be modified by actions of market players and government (regulation and taxation). Energy demand management implies actions that influence demand for energy.

Reducing energy demand is contrary to what both energy suppliers and governments have been doing during most of the modern industrial history. Whereas real prices of various energy forms have been decreasing during most of the industrial era, due to economies of scale and technology, the expectation for the future is the opposite. Previously, it was not unreasonable to promote energy use as more copious and cheaper energy sources could be anticipated in the future or the supplier had installed excess capacity that would be made more profitable by increased consumption. ...

In the centrally planned economies subsidising energy was one of the main economic development tools. Subsidies to the energy supply industry are still common in some countries. A planned economy is an economic system in which economic decisions are made by centralized planners who determine what sorts of goods and services to produce and how they are to be priced and allocated, and may include state ownership of the means of production. ...

Contrary to the historical situation, energy prices and availability are expected to deteriorate. Governments and other public actors, if not the energy suppliers themselves, are tending to employ energy demand measures that will increase the efficiency of energy consumption.
