CSP Solar Energy

"CSP" stands for "Concentrated Solar Power." The term refers to the type of solar power which is created by concentrating sunlight onto a small area, thus creating an intense light and heat which can in turn generate power and electricity. CSP is one of several technologies which have been developed in order to harness the energy emitted by the sun and turn it into useable electricity.
The main difference between CSP energy systems and other solar power systems (such as photovoltaics and solar heating), is that CSP uses mirrors and reflectors in order to focus concentrated sunlight on a specific location.
How CSP Solar Energy Systems Work
A simple but accurate comparison to CSP Solar Energy is the use of a magnifying lens to focus sunlight on a specific area. But the target of a CSP system is to heat fluids, not ants or other luckless insects.
The heated fluids are then turned into steam. The steam is in turn forced through a fan, and is used to drive a regular steam turbine, which uses its turning motion to generate electricity through electromagnetic means.
One of the advantages of CSP is that it is completely compatible with the contemporary power generators which are used in conventional power plants. But in the case of CSP solar energy, the "fuel" used to generate steam is sunlight, not fossil fuels such as oil and coal.
You may be surprised to learn that in the USA, several CSP power plants are already up and running - and that they have performed reliably for the past fifteen years.
At the time of this writing, the least expensive method of using solar power to produce electricity is the to use CSP systems.
Research and development projects are underway, with the aim of reducing costs even further, so that the cost of producing electricity with solar power can eventually compete with the costs of energy production in conventional power plants.
CSP solar energy is just one of many methods of generating alternative energy on a broad scale.
Another example of broad scale solar power production is the use of solar towers. These towers use an assortment of moving mirrors (called heliostats) to continuously reflect sunlight toward a central area at the top of the tower. The heliostats are set up so that they move with the movement of the sun, thus maintaining optimal reflecting power.
