Concentrating Solar

Concentrating Solar Power (or "CSP") refers to the type of solar energy that is created by concentrating sunlight into a small area, thus creating intense light and heat, which in turn generates energy and electricity. Concentrating Solar Power is one of several alternative energy technologies that have been developed with the order to harness the energy emitted by the sun and transform it into usable electricity.

The main difference between the concentrated solar power (CSP) systems energy and solar energy systems (such as photovoltaic and solar heating) is that the concentrated solar energy using mirrors and reflectors to concentrate sunlight concentrated in a specific place.

How Solar Power Systems Work

A simple comparison but needs to CSP is the use of a magnifying glass to focus sunlight on a specific area. But the goal of a CSP is to heat the fluids are not ants or other insects with no luck.

Fluids heated by concentrated solar energy is then converted into steam. Water vapor is itself forced through a ventilator, and is used to drive a regular steam turbine, which uses the proposed change to generate electricity through electromagnetic means.

One advantage of the concentrated solar energy is that it is fully compatible with existing power generators used in conventional power plants. But in the case of solar CSP, the fuel used to generate steam is sunlight, not fossil fuels like oil and coal.

You may be surprised to learn that in the U.S., several CSP power plants are already under way - and have performed reliably in the past fifteen years.

At the time of this writing, the least expensive method of using solar energy to produce electricity is to use energy systems concentrated solar.

Research and development projects are underway, with the aim of reducing costs even further, so that the cost of producing electricity solar energy can eventually compete with the costs of energy production in modern conventional power plants.

Concentrating Solar Power is one of several methods of generating solar energy and alternative energy on a broad scale. Another example of large scale solar energy production is the use of pylons solar. These towers use a variety of movable mirrors (called heliostats) that continuously reflect sunlight into a central area at the top of the tower. These heliostats are configured so they can track the movement of the sun, thus maintaining the strongest possible reflecting power.
