Concentrated Solar Power
Concentrated Solar Power (or”CSP”) refers to the type of solar energy which is created by concentrating sunlight onto a small area, thus creating intense light and heat, which in turn generates power and electricity. Concentrated Solar Power is one of several alternative energy 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 concentrated solar power (CSP) energy systems and other solar power systems (such as photovoltaics and solar heating), is that concentrated solar power uses mirrors and reflectors in order to focus concentrated sunlight on a specific location.
How Concentrated Solar Power Systems Work
A simple but accurate comparison to Concentrated Solar Power 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 fluids heated by this concentrated solar energy 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 advantage of concentrated solar power 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 concentrated solar power 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 modern conventional power plants.
Concentrated Solar Power is one of several methods of generating solar power and alternative energy on a broad scale. Another example of broad scale solar power production is the use of solar power 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. These heliostats are set up so that they follow the movement of the sun, thus maintaining the strongest reflecting power possible.

Advantages and Disadvantages of SOLAR ENERGY
Many of us know that solar energy is good, but few really understand why.
Therefore, I compiled a comprehensive list of solar energy advantages and disadvantages that will enable you to make an educated decision whether on not Solar Power is right for YOU. Solar Energy Advantages
1. Saves you money
After the initial investment has been recovered, the energy from the sun is practically FREE. The recovery/ payback period for this investment can be very short depending on how much electricity your household uses. Financial incentives are available form the government that will reduce your cost. If your system produce more energy than you use, your utility company can buy it from you, building up a credit on your account! This is called net metering. It will save you money on your electricity bill if you have one at all. Solar energy does not require any fuel. It’s not affected by the supply and demand of fuel and is therefore not subjected to the ever-increasing price of gasoline. The savings are immediate and for many years to come. The use of solar energy indirectly reduces health costs.
2. Environmentally friendly
Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment. It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulphur dioxide or mercury into the atmosphere like many traditional forms of electrical generations does. Therefore Solar Energy does not contribute to global warming, acid rain or smog. It actively contributes to the decrease of harmful green house gas emissions. It’s generated where it is needed. By not using any fuel, Solar Energy does not contribute to the cost and problems of the recovery and transportation of fuel or the storage of radioactive waste.
3. Independent/ semi-independent
Solar Energy can be utilized to offset utility-supplied energy consumption. It does not only reduce your electricity bill, but will also continue to supply your home/ business with electricity in the event of a power outage. A Solar Energy system can operate entirely independent, not requiring a connection to a power or gas grid at all. Systems can therefore be installed in remote locations (like holiday log cabins), making it more practical and cost-effective than the supply of utility electricity to a new site. The use of Solar Energy reduces our dependence on foreign and/or centralized sources of energy, influenced by natural disasters or international events and so contributes to a sustainable future. Solar Energy supports local job and wealth creation, fuelling local economies.
4. Low/ no maintenance
Solar Energy systems are virtually maintenance free and will last for decades. Once installed, there are no recurring costs. They operate silently, have no moving parts, do not release offensive smells and do not require you to add any fuel. More solar panels can easily be added in the future when your family’s needs grow.
Solar Energy Disadvantages
The initial cost is the main disadvantage of installing a solar energy system, largely because of the high cost of the semi-conducting materials used in building one. The cost of solar energy is also high compared to non-renewable utility-supplied electricity. As energy shortages are becoming more common, solar energy is becoming more price-competitive. Solar panels require quite a large area for installation to achieve a good level of efficiency. The efficiency of the system also relies on the location of the sun, although this problem can be overcome with the installation of certain components. The production of solar energy is influenced by the presence of clouds or pollution in the air. Similarly, no solar energy will be produced during nighttime although a battery backup system and/or net metering will solve this problem. See www.dsireusa.org for details on how net metering allows you to save electricity and money. As far as solar powered cars go – their slower speed might not appeal to everyone caught up in today’s rat race.
