Waves are primarily created by wind, so the power available from waves tends to follow that available from wind, but due to the mass of the water is less variable than wind power.
Wind power is proportional to the cube of the wind speed, while wave power is proportional to the square of the wave height.
Historically grid operators use day ahead forecasting to choose which power stations to make up demand each hour of the next day, and adjust this forecast at intervals as short as hourly or even every fifteen minutes to accommodate any changes.
Typically only a small fraction of the total demand is provided as spinning reserve. Some projections suggest that by almost all energy could come from non-dispatchable sources — how much wind or solar power is available depends on the weather conditions, and instead of turning on and off available sources becomes one of either storing or transmission of those sources to when they can be used or to where they can be used.
Hydrogen is not an energy source, but is a storage medium. A cost analysis will need to be made between long distance transmission and excess capacity.
The sun is always shining somewhere, and the wind is always blowing somewhere on the Earth, and during the s or s it is predicted to become cost effective to bring solar power from Australia to Singapore.
In locations like British Columbia , with abundant water power resources, water power can always make up any shortfall in wind power,  and thermal storage may be useful for balancing electricity supply and demand in areas without hydropower.
Wind and solar are somewhat complementary. A comparison of the output of the solar panels and the wind turbine at the Massachusetts Maritime Academy shows the effect.
There is always no solar at night, and there is often more wind at night than during the day, so solar can be used somewhat to fill in the peak demand in the day, and wind can supply much of the demand during the night.
There is however a substantial need for storage and transmission to fill in the gaps between demand and supply. The variability of sun, wind and so on, turns out to be a non-problem if you do several sensible things.
One is to diversify your renewables by technology, so that weather conditions bad for one kind are good for another. Second, you diversify by site so they're not all subject to the same weather pattern at the same time because they're in the same place.
Third, you use standard weather forecasting techniques to forecast wind, sun and rain, and of course hydro operators do this right now.
The combination of diversifying variable renewables by type and location , forecasting their variation, and integrating them with despatchable renewables, flexible fueled generators, and demand response can create a power system that has the potential to meet our needs reliably.
Integrating ever-higher levels of renewables is being successfully demonstrated in the real world: . Mark A. Delucchi and Mark Z.
Jacobson identify seven ways to design and operate variable renewable energy systems so that they will reliably satisfy electricity demand: .
Jacobson and Delucchi say that wind, water and solar power can be scaled up in cost-effective ways to meet our energy demands, freeing us from dependence on both fossil fuels and nuclear power.
A more detailed and updated technical analysis has been published as a two-part article in the refereed journal Energy Policy.
An article by Kroposki, et al. These systems must be properly design to address grid stability and reliability. Renewable energy is naturally replenished and renewable power technologies increase energy security because they reduce dependence on foreign sources of fuel.
Unlike power stations relying on uranium and recycled plutonium for fuel, they are not subject to the volatility of global fuel markets. An accidental or intentional outage affects a smaller amount of capacity than an outage at a larger power station.
The International Energy Agency says that there has been too much attention on issue of the variability of renewable electricity production. Variability will rarely be a barrier to increased renewable energy deployment when dispatchable generation is also available.
But at high levels of market penetration it requires careful analysis and management, and additional costs may be required for back-up or system modification.
In , the Intergovernmental Panel on Climate Change , the world's leading climate researchers selected by the United Nations, said "as infrastructure and energy systems develop, in spite of the complexities, there are few, if any, fundamental technological limits to integrating a portfolio of renewable energy technologies to meet a majority share of total energy demand in locations where suitable renewable resources exist or can be supplied".
This approach could contain greenhouse gas levels to less than parts per million, the safe level beyond which climate change becomes catastrophic and irreversible.
An intermittent energy source is any source of energy that is not continuously available for conversion into electricity and outside direct control because the used primary energy cannot be stored.
Intermittent energy sources may be predictable but cannot be dispatched to meet the demand of an electric power system.
The use of intermittent sources in an electric power system usually displaces storable primary energy that would otherwise be consumed by other power stations.
Another option is to store electricity generated by non-dispatchable energy sources for later use when needed, e.
A third option is the sector coupling e. The use of small amounts of intermittent power has little effect on grid operations. Using larger amounts of intermittent power may require upgrades or even a redesign of the grid infrastructure.
The penetration of intermittent renewables in most power grids is low, global electricity production in was supplied by 3. The intermittency and variability of renewable energy sources can be reduced and accommodated by diversifying their technology type and geographical location, forecasting their variation, and integrating them with dispatchable renewables such as hydropower, geothermal, and biomass.
Combining this with energy storage and demand response can create a power system that can reliably match real-time energy demand.
A research group at Harvard University quantified the meteorologically defined limits to reduction in the variability of outputs from a coupled wind farm system in the Central US:.
The problem with the output from a single wind farm located in any particular region is that it is variable on time scales ranging from minutes to days posing difficulties for incorporating relevant outputs into an integrated power system.
The high frequency shorter than once per day variability of contributions from individual wind farms is determined mainly by locally generated small scale boundary layer.
The low frequency variability longer than once per day is associated with the passage of transient waves in the atmosphere with a characteristic time scale of several days.
The high frequency variability of wind-generated power can be significantly reduced by coupling outputs from 5 to 10 wind farms distributed uniformly over a ten state region of the Central US.
Large, distributed power grids are better able to deal with high levels of penetration than small, isolated grids. Our magic isn't perfect You can help our automatic cover photo selection by reporting an unsuitable photo.
