Global carbon emissions have become a central focus of developed nations in attaining the twin goals of energy security and sustainability. In order to achieve this twin target of security and sustainability, there is an acute need to produce energy from the sustainable sources such as wind, solar, geothermal and biomass. The global financial crisis has provided opportunities to governments to move forward in altering the present energy generation mix. The financial stimulus packages announced by the major developed nations have allotted almost $512 billion to green energy. On the basis of announced

stimulus packages to 31st March 2009, the observation can be drawn that the Asian nations, especially China, have contributed the most to the green energy projects. South Korea has allotted the maximum amount to the green energy, followed by China.

Global Solar Thermal market was concentrated in the US only till Spain joined in 2007. Since 2007, the sector has broadened its geographical reach and Australia and Morocco has also started the solar thermal plants. Due to the high energy efficiency, the technology is gathering the interest of the other nations with the planned projects coming online from 2010. Global solar thermal cumulative installed capacity has grown from 354 MW (Megawatts) in 2001 to 697 MW in 2009 at a CAGR of 9% per annum. However, the planned projects that are coming online from 2010 onwards are anticipated to accelerate the CAGR to 46% per annum during 2010 to 2020. In 2020, the solar thermal power capacity is expected to reach at 122,252 MW from 2,715 MW in 2010. The annual installations capacity is expected to witness a big surge in the coming decade, primarily due to the significant capacity additions in the US and Spain. Additionally, the capacity addition will be supported, as many other countries like Australia, China, the United Arab Emirates (UAE), Algeria and Italy are coming up with the CSP (Concentrated Solar Power) projects.

The US solar thermal market grew at a CAGR of 2% per annum from 2001 to 2009. However, the government encouragement for the sector is expected to lift CAGR to astonishing levels of 46% per annum for the period 2010 to 2020. The installations are expected to pick up pace as high capacity plants come online during the period. California is expected to lead the CSP installations with almost nine projects with a capacity of more than 500 MW expected to come online during the period of which one project is having capacity of 1,000 MW. The sector growth will continue to be robust till 2020 as the RPS (Renewable Portfolio Standards) targets for the states will continue encouraging solar thermal power generation in the country.

Concentrating Solar Power Systems

Sunday, June 13th, 2010

This type of system heats oil that is flowing through the pipe. The oil is hot and that is why it is used to boil water to power a steam generator which in turns powers electricity.

The reason that this system works so well is because the U-shaped mirrors attracts and collects the suns heat which is then transferred onto the receiver. The receiver absorbs the heat and transfers into fluid which helps to power the engine. The heat causes the fluid to swell up against the piston and that produces mechanical power. This type of power can be used to run things like generators or even an alternator that will produce electricity. This system works great when because it uses molten salt that flows through the receiver. When the salt heats up it can generate electricity through the steam generator. The salt holds in the heat for several days before it has to be converted into electricity. Because this system uses so many panels it is mainly used for industrial solar power where acres of land can be donated to the Parabolic Trough. There can be enough power in the network that can create energy for several days or more. Because this system is so large that it allows the heat that it saves to be transferred days later.

Through this project and other solar power projects we can understand fully how solar power works. When we see how much solar power is conserved using these U shaped mirrors we can also understand how much energy is lost. Using concentrating solar power systems are beneficial to the businesses that use them because they won’t have so much time down when the power fails. Machinery is their only major concern and as long as their machines are taken care of there should be no problems. Industrial type of solar power can attract and trap a lot of heat from the sun during the day, especially using mirrors that will reflect the sunlight. It also helps to have this type of solar power out in an open field free of trees and vegetation that may grow around and at some point crowd the solar light out.

Scientist are continuously studying this theory as businesses use it to power their machinery. Steam power was what was used from the beginning with solar power and is still what most systems depend on to service their production needs. In the future, fields may eventually be full of mirrors that somewhat point up to the sky in hopes of generating enough sunlight to heat the world. Until then we will use the traditional methods of heating water, heating our homes and powering our electricity.

I have come across a great site that has the #1 home solar power energy system It is a complete step-by-step fully illustrated manual + easy to follow videos that will have you generating your own electricity for less than $200! Guaranteed.

Concentrated Solar Power

Tuesday, June 8th, 2010

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.
