A new energy infrastructure must provide energy at least
as reliable as the existing infrastructure. WWS(Wind,Water,Sun) technologies
generally suffer less downtime than traditional sources. Coal plants in the USA
are on average 12.5% year offline for scheduled and unscheduled maintenance.
Modern wind turbines have a down time of less than 2 percent on land and less
than 5% offshore.
Photovoltaic systems also are stop less than 2 percent. Furthermore, when a wind turbine, solar or inverter is not working, only a small part of the installation is affected and its loss is a small fraction of production; moreover when a plant loses the connection; a gas natural plant or coal, or nuclear, this makes it loses a large part of the production.
One of the major problems facing energy supply systems is
the difficulty and cost of storing energy during periods of low demand for use
during peak demand, this is especially relevant in the case of renewable energy, so that they can be a realistic alternative to the energy obtained from
conventional fossil fuel. For example, wind turbines depend of the existence of
wind, a certain intensity, to produce energy, but the wind does not understand
of demand seasonal or rolling load, so there are situations in
which the electrical production exceeds the demand and others in which the
opposite occurs. This also applies to a greater or lesser degree, to other
renewables energies.
The main challenge of the WWS, is that the wind does not always blow and the sun does not always shine in a particular location. Intermittent problems can be mitigated by a smart balance of sources, such as generating base with geothermal energy and tidal wave energy or energy storage. The wind energy is often abundant at night when there is no sun, or the sun during the day when may be no wind. Sometimes a reliable source like hydropower can connect or disconnect quickly to meet peak demand or reduce supply. Also in case of having pumping can be stored.

Another example of green energy technology is wind parks that are only 100 to 200
miles away can compensate zero hours of power from other wind parks where there
is no wind. Also useful is the interconnection of geographically distant
sources that can support one another, installing smart electric meters in homes
that automatically recharge electric vehicles when demand is low or delivering
electricity to the grid when they are loaded and stopped.
