'''Paring green energy production to consumption''' is the act of aligning electricity production to electricity consumption.
Renewable energy, after its generation, needs to be stored in a medium for use with autonomous devices as well as vehicles<!-- what does "autonomous devices mean! Please don't use such puzzling words!-->. Also, in order to provide household electricity in remote areas (that is areas which are not connected to the [[Mains electricity|mains electricity grid]]), energy storage is required for use with renewable energy. Energy generation and consumption systems used in the latter case are usually [[stand-alone power system]]s.

Some examples are:
* energy carriers as [[hydrogen]], [[liquid nitrogen]], [[compressed air]], [[oxyhydrogen]], [[Battery (electricity)|batteries]], to power vehicles.
* [[flywheel energy storage]], [[pumped-storage hydroelectricity]] is more usable in stationary applications (eg to power homes and offices. In household power systems, conversion of energy can also be done in order to reduce smell. For example organic matter such as cow dung and spoilable organic matter can be converted to [[biochar]]. In order to eliminate emissions, [[carbon capture and storage]] is then used.
Usually however, renewable energy is derived from the mains electricity grid. This means that energy storage is mostly not used, as the mains electricity grid is organised to produce the exact amount of energy being consumed at that particular moment. Energy production on the mains electricity grid is always set up as a combination of (large-scale) renewable energy plants, as well as other power plants as [[fossil-fuel power plant]]s and [[nuclear power]]. This combination however, which is essential for this type of energy supply (as eg wind turbines, solar power plants etc.) can only produce when the wind blows and the sun shines. This is also one of the main drawbacks of the system as fossil fuel powerplants are polluting and are a main cause of [[global warming]] (nuclear power being an exeption). Although fossil fuel power plants too can made emissionless (trough carbon capture and storage), as well as renewable (if the plants are converted to e.g. biomass) the best solution is still to phase out the latter power plants over time. Nuclear power plants too can be more or less eliminated from their problem of nuclear waste trough the use of [[nuclear reprocessing]] and newer plants as [[Fast breeder reactor|fast breeder]] and [[nuclear fusion]] plants.
Renewable energy power plants do provide a steady flow of energy. For example hydropower plants, ocean thermal plants, osmotic power plants all provide power at a regulated pace, and are thus available power sources at any given moment (even at night, windstill moments etc.). At present however, the number of steady-flow renewable energy plants alone is still too small to meet energy demands at the times of the day when the irregular producing renewable energy plants cannot produce power.
Besides the greening of fossil fuel and nuclear power plants, another option is the distribution and immediate use of power from solely renewable sources. In this set-up energy storage is again not necessary. For example, [[TREC]] has proposed to distribute solar power from the Sahara to Europe. Europe can distribute wind and ocean power to the Sahara and other countries. In this way, power is produced at any given time as at any point of the planet as the sun or the wind is up or ocean waves and currents are stirring. This option however is probably not possible in the short-term, as fossil fuel and nuclear power are still the main sources of energy on the mains electricity net and replacing them will not be possible overnight.
Several [[Grid energy storage|large-scale energy storage suggestions for the grid]] have been done. This improves efficiency and decreases energy losses but a conversion to a energy storing mains electricity grid is a very costly solution. Some costs could potentially be reduced by making use of energy storage equipment the consumer buys and not the state. An example is [[Grid energy storage|car batteries]] in personal vehicles that would double as an energy buffer for the electricity grid. However besides the cost, setting-up such a system would still be a very complicated and difficult procedure. Also, energy storage apparatus' as car batteries are also built with materials that pose a threat to the environment (eg sulphuric acid). The combined production of batteries for such a large part of the population would thus still not quite environmental. Besides car batteries however, other [[Grid energy storage|large-scale energy storage suggestions for the grid]] have been done which make use of less polluting energy carriers (eg compressed air tanks and flywheel energy storage).
