Renewable Energy Like Solar Energy Can Prevent the World From Devastation…………
May 15, 2013 | 
Author Our body needs energy to work and in the same way, a machine needs electricity or energy of any substance to run. For different machines and automobiles we use different means of energy such as; Coal, petroleum and natural gas. But these days the use of renewable energy is in vogue which is the energy produced out of the natural sources like sunlight, wind, tide and rain. The major types of renewable energy are: Solar energy, Wind energy, Bio mass energy.
The renewable energy is preferred more by the whole today because of its extra-ordinary advantages. We have been using the energy of the fossil fuels, produced by burning it which has kept the whole world on the edge of the devastation. Today, the world is towards the way of harnessing the natural sources for the energy to save the world from further global warming. The renewable energy does not emit any kind of toxic gases which can be fatal for the earth and another merit is it is the replenished energy. Among all the natural sources, the sun is the incessant mean, giving amazing output. The sun throws the heat and light directly on the earth almost daily (except few places) and the solar collectors collect the rays and transfer them into the form of electricity or heat which can be very helpful. Solar energy provides electricity to heat water and to heat or cool homes, businesses or industry. It is being preferable because it is a clean and renewable source of energy. The sunlight when converted into electricity is also called the solar power. If the use of renewable energy will be increased then the next generation will be able to live in the realm of pure environment.

Solar Panel And Their Usage
As the prices of oil and gas continue to rise, the installation of solar panels is bringing many families solace and stability. The sun offers an almost infinite source of energy. No wonder so many people are rushing to install solar panels. Indeed, their popularity is increasing so rapidly that manufacturers of solar panels are having difficulty keeping up with demand. USA Energy Guide can help you calculate how much money you could be saving by taking advantage of solar power for your home or business.
Two Types of Solar Panels
Solar panels come in two types. There are solar energy panels in the form of ‘solar thermal collectors’. These focus solar energy into a liquid medium, usually water, heating the liquid that is then utilized as and where it is required. The other of the two types of solar panels is known as the photovoltaic module. These solar panels convert the sun’s energy into electricity, which can then be distributed immediately or stored within a battery to be used later.
Solar panels have been commonplace for decades. Think of calculators and watches. Many swimming pools have been heated using solar panels for years. These days, the electricity to homes and offices often comes from the cleaner alternative energy source of bigger, better, more efficient solar panels.
The influence of solar panels has spread so wide that even the National Grid takes some of their power from solar energy panels. Learn more about the types of residential solar panels.
How Do Solar Panels Work?
Both photovoltaic (PV) and solar thermal solar panels are made of special materials, most frequently silicon. They act as semiconductors. When sunlight hits the solar energy panels, some of the energy is absorbed within the semiconductor material. That energy knocks electrons within the silicon loose, allowing them to flow freely.
Once the electric fields within solar panels are freed by light energy, they force electrons to flow in one specific way. This flow of electrons is also known as a current. By simply placing metal contacts on the top and bottom of the solar energy panels, the current can be drawn off as electricity to be used externally.
The solar panels have built-in electric fields that, when combined with the current described above, will give us what we call a wattage. We use this to describe the power of our solar energy panels.
Why Solar Panels?
There are lots of great reasons to install solar panels in your house. Top of the list is the huge savings you will make on your utility bills. Many people feel good that they are reducing their carbon footprint. Solar panels give off almost zero carbon dioxide emission. Solar panels reduce our carbon dioxide emissions by approximately 1.2 million tonnes per annum.
Another benefit is the freedom of not being tied to the National Grid. With solar panels fully fitted, power cuts and unexpectedly increased electricity bills become a thing of the past.
Solar panels are perfect for those living in remote areas with limited coverage by the National Grid.
Installing Solar Panels On Your Home
Though there are some very good guides to making your own solar panels and then installing them into your home on a DIY basis, it is advisable to seek out a professional solar panels installation company. Ideally, the installers of your solar panels should be certified by the Low Carbon Buildings Program.
It is not advisable to try to install solar panels without full training. Make certain that your solar panels conform to the local standards laid out by the authorities there. There is a number of complex technical electrical issues to be resolved as well as full safety codes required.
Because of their weight, solar panels often need to be attached to a separate roofing support system.
Professional installers of solar panels should have gone through all the red tape and complicated issues so you don’t have to.
Getting Planning Permission For Solar Panels Installation
Solar panels are most frequently fitted to the roof or along an external wall of the home. Be sure to check with the local council before doing this. The local authorities in most countries agree that it is acceptable to install roof mounted solar panels. Some places do require detailed listed criteria though.
In England, for example, solar panels of up to 100mm in depth can be laid across a tilted roof without requiring planning permission. In Scotland, Wales and Northern Ireland the local authorities have not finalized their legislation relating to solar energy panel, so be sure to check before you go rushing in.
The Outlook For Solar Panels
As people become more and more aware of global warming and climate change, so the demand for good quality solar panels is increasing. The momentum among people is to move away from old-school fossil fuels in favor of alternative, more sustainable energy options. These include hydrogen, hydro-electricity, solar power, wind and wave.
Solar power is one of the most bountiful of the possible energy supplies that we have here on Planet Earth. As the technology behind solar panels improves in terms of their efficiency, so the cost of installing solar panels is falling. When added to a range of governmental subsidies, tax credits, rebates and grants, the widespread installation of solar panels onto the average householder’s roof is becoming more and more realistic. As the prices are falling further thanks to local competition in the marketplace, so, it would seem that the future of solar panels is very bright indeed.

An Overview Of Solar Energy And Other Renewable Energy Sources
When we talk about renewable energy we are referring to power that delivers energy from resources that will not be depleted because of our use of them. Renewable energy is an alternative to non-renewable fossil fuel energy for reasons other than the factor of non-depletion.
One basic benefit of renewable energy, and the reason environmentalists all over the globe are advocate its use, is that it does give off greenhouse gases and other harmful pollutants as do the by-products of burning fossil fuel for energy. Renewable energy such as solar power, water power and wind power, while the widespread discussion of which is new, are anything but new.
In both newly developing and highly developed countries wind, sun and water have long been used as power sources, though not to the extent of providing the primary energy source for large metropolitan communities.
The mass production of such renewable energy is become commonplace in recent years as more and more people come to realize how climate is changing due to the pollution of fossil fuel gases, due to the exhaustion of the availability of these fossil fuels and the political and social concerns of energy sources such as nuclear power.
Many countries and non-profit environmentally-conscious organizations are encouraging the use of renewable energy sources by passing legislation on tax incentives for their use and subsidies to offset the added expense of converting from fossil fuel to renewable energy.
The flow of renewable energy involves phenomena that occur naturally in our world. Tides, sunlight, wind and heat derived by geothermal occurrences all provide renewable energy. Each of these energy sources is unique both in where we can use them and how.
Most technology that converts renewable energy into power sources we can use are powered at least in part by the Sun if not directly at least indirectly. The earths atmospheric system stays in such equilibrium that the heat that it gives off radiates into space to an amount equal to the radiation that comes to earth from the sun.
The result of this energy level within the atmosphere is roughly translated to the climate of the earth. The water of the earth, also referred to its hydrosphere, absorbs a lot of the radiation that comes to us from the sun.
Most of the radiation gets absorbed at the lower latitudes of the earth that exist around the equator. This energy gets dissipated all around the globe, however, in the form of ocean and wind currents.
The motion of the ocean waves might have a role in transference of mechanical energy between the ocean and the earths atmosphere by way of wind stress. Solar energy also provides the means by which precipitations is distributed and then tapped by hydroelectric energy projects as well as plant growth that then creates biofuels.
Indoor Solar Cells? A 500 Megawatt Proposal
Complete video at: fora.tv Howard Clearfield, CTO of G24 Innovations, discusses potential applications of dye-sensitized solar cells. Since these cells operate indoors, Clearfield explains using the technology with indoor devices that draw standby power, like televisions, would take over 500 megawatts of electricity off the grid. —– Finding economic ways to capture and convert energy from our largest renewable energy source, the sun, is becoming more urgent as the worlds supply of fossil fuels vanishes. Now, the development of a new generation of solar cells might lead the way toward a better future. Graetzel cells, named for Professor Michael Graetzel of the Ecole Polytechnique federale de Lausanne (EPFL) in Switzerland, are dye-sensitized solar cells that are thin, flexible, and come in many shapes and colors, allowing them to answer different functional needs.

Solar Tower – renewable energy green global warming
EnviroMission Limited (www.enviromission.com.au) produced this 5 minute video on the pilot plant in Spain. It is an older video (2000) but gives a decent understanding of the solar tower concept. EnviroMission, Ltd. (US Market: EVOMY, Australian Exchange: EVM) is a renewable energy developer of sustainable “green” energy solutions for the energy market. EnviroMission aims to be one of Australia’s leading producers of clean renewable energy. EnviroMission holds the proprietary rights to Solar Tower technology, a large-scale renewable energy technology based on simple fundamentals of physics — hot air rises. Solar Tower technology has the potential to offer competitive renewable energy with equal reliability to fossil fuel generators. A single 200MW Solar Tower power station will provide enough electricity to power around 400000 households. The energy output will represent an annual saving of more than 1960000 tonnes of greenhouse CO2 gases from entering the environment when compared to brown coal emissions in Victoria. The greenhouse savings equate to the removal of approximately 500000 cars from the road. The Australian Solar Tower project consists of six distinct phases, the first two of which (project optimization and pre-feasibility commercialization) have already been completed. The third phase (final feasibility), paving the way for the implementation of the next three phases (final design, construction, and commercial operation).
