I hope for more advances in clean energies.
según las circunstancias se puede generar energía. Buena lección.
It is important to embrace new technology which can help countries storing energy.Entry is stored in a grid.You need power lines to transport energy.
What is baseline energy?
Electricity must be transported from the production site to the end consumer taking into account fluctuations in demand.
As far as human needs are concerned, there is a marked difference between ‘dilute’ and ‘concentrated’ energy. Water vapour in the atmosphere, for example, has considerable potential energy since a huge mass globally (about 13 × 1015 kg) is held high above the Earth's surface. But this potential energy represents a very dilute form of energy - falling rain could not turn a water wheel.
It is only when energy can be ‘concentrated’ that it can be put to good use - in this case by rainfall accumulating in streams and rivers, or being stored in reservoirs at high elevations. The concentration can be expressed colloquially in terms of energy density, which is the amount of energy stored by a resource divided by the volume of the space that it occupies.
Some forms of energy are relatively difficult to concentrate, so have a low energy density, whereas others are easier to concentrate. The energy contained in moving air is rather difficult to concentrate; windmills and wind farms have to be sited where natural factors enhance wind speed and constancy. Solar power has a low energy density, so requires large collecting devices.
The potential energy of rain is naturally concentrated and held in mountain lakes. We concentrate this energy artificially when rainwater is stored in a reservoir. This emphasises why fossil fuels are so valuable as they represent naturally concentrated forms of the solar energy that reached the Earth millions of years ago. The ultimate form of concentrated energy is matter itself, in the form of nuclear energy.
To be useful to us, energy must be available where and when we want it, and in a form and in amounts we can handle. Storing most forms of energy is very difficult. We have to re-heat our homes daily in the wintertime because they constantly lose heat, despite our attempts to insulate them. We cannot store light when the Sun goes down - we have to turn electricity into light until the Sun reappears.
In fact, only two forms of energy are truly storable. Potential energy can be stored almost indefinitely by mechanical means, as in springs or lifted weights - the basis of clocks. Far more convenient is storage that exploits chemical energy - batteries, or even better, chemical fuel.
Fuels are compounds whose combustion liberates a large amount of energy per unit mass: they commonly have a high energy density. Wood was the major fuel before the Industrial Revolution, and remains the most important fuel for many non-industrial societies today. Wood, and other plants that can be used as fuels, produce biomass energy.
As industry develops, energy demands grow and fuels with higher convertible energy content per unit mass are needed. Modern energy supply is centred on the fossil fuels: coal, oil and gas. Note that although the isotopes whose fission or fusion forms the basis for nuclear power are not burnt, they are generally known as nuclear fuels.
A further advantage of fuels as energy sources is their transportability, so that conversion can take place on selected sites or in mobile units. Highly concentrated fuels require less energy to transport than those with a low energy density but since lots of energy can be released accidentally from badly handled concentrated energy sources, care has to be taken to ensure that transport is safe.
For some applications, such as cars, generating energy from stored chemical energy has the advantage of the ease of transport of small amounts of fuel.
