Solar power has been around since the Seventh Century BC. 
In ancient Egypt, heat from the sun was used to bake a mixture of straw and mud into bricks which were used for construction.   The ancient Greeks and Romans were the first to use what we now call passive solar design – architecture designed to optimally harness the sun’s rays for light and heat. 
By building houses that faced south, they were able to get the most out of the winter sun.In this way, they were also able to cut back on firewood which was not always readily available, making early use of renewable energy.The Romans took solar design a step further by covering south-facing building openings with glass or mica to prevent the heat of the winter sun from escaping, and even made a law against obscuring a neighbour’s access to sunlight.
Much less passive was the use of solar energy by the Ancient Greeks, who used bronze shields to direct the sun’s rays onto the wooden ships of the Roman army to set fire to them.By building their houses into the sides of rocky cliffs, some native American cultures were able to get the most out of the heat trapped by the rocks during the day.
The world’s first solar collector is said to have been built in 1767 by the Swiss Horace de Saussure, but it was only in 1839 when Frenchman Edmond Becquerel first showed photovoltaic activity that the foundation for modern solar power research was set.His major discovery was that exposure to light increased electric current in certain materials.
The French continued experimentation with solar power, with mathematician Auguste Mouchout inventing the first active solar motor as well as a steam engine powered entirely by the sun.Both of these inventions failed to get off the ground because of the prohibitive cost of production.
Around the globe, scientists were experimenting with solar energy.In the lae 1870s, William Grylls Adams worked out that when light was shone on selenium, it shed electrons, thereby creating electricity. 
Albert Einstein’s theories on the photoelectric effect – involving the generation of electricity through solar cells – won him the 1921 Nobel Prize in Physics.
In the 1950s, Bell Laboratories (now known as AT & T Laboratories) developed the first silicon solar cell which could generate a measurable electric current.This was the first time that a cell had been developed that could convert the sun’s energy to power everyday appliances.
The first practical application of photovoltaic silicon solar cells also came in the 1950s with the launch of the satellite, Vanguard 1.  In 1981, the first solar powered aircraft flew from France to England powered by 16 000 solar cells giving off 3 000 watts of power.
The Arab Oil Embargo in 1973 was the catalyst for solar energy research to gain momentum as western economies looked for ways to reduce their dependence on oil.  The development of a cost-effective solar cell by Dr Elliot Berman in the 1970s was a major breakthrough, opening up a range of applications such as navigation warning lights as well as uses in remote locations. 
Concern for the environment has galvanised research into finding viable alternatives to fossil fuels, such as wind power, geothermal and solar power.And whilst solar technology today is powering far more than a hand-held radio, the basic idea of solar power has remained the same since ancient times – it is a viable renewable energy source.

The importance of renewable energy sources shouldn’t be understated, especially in times like these where both greenhouse gases and global warming are on the rise. Paying attention to the reduction of carbon emissions and further harmful effects upon the environment is essential.

It’s important that the population do what they can to minimize their impact on the environment by looking at other more environmentally friendly means of heating their homes for instance.

For those willing to put in some effort in relation to improving the environment, governments normally offer tax breaks, grants or concessions. However, sometimes it can be hard to know what’s on offer and how to get them (how to get solar power grants for example).

So, how does one find out whats on offer and how do you go about getting grants, concessions or tax breaks?

This best place to start is the ‘Database of State Incentives for Renewable and Efficiency’ website. The site provides a map of the United States which allows Americans to click on the state in which the live and a host of further links will be presented that will outline the incentives or grants which are on offer at individual state levels.

Before you jump on the renovation or implementation of these green friendly resources, check out this site first which will help you know what you’re entitled to and what money you can save. This is probably the first step in order to understand how to get solar power grants for instance.

Some of the items presented there include…

– The type of policy or incentive being offered. For example, is it a tax credit, net metering, etc.?
– What sectors are entitled to the benefits, whether it is residential, government or commercial premises.
– Who is actually offering the grant? Is it a state or federal one?
– A link to the website in charge of the offering of the grant or incentive.
– The specific purpose the grant is being offered for.

Both state and federal governments offer grants and hopefully this website will point you in the right direction in order to receive them. You could soon be receiving thousands of dollars to use for the installation of one or more renewable energy, or environmentally friendly, facilities..

Though your can find lots of information on how to get solar power grants from just a single visit to these websites, it’s advisable to regularly monitor them as they updated every couple of months. Both state and federal governments are constantly increasing what’s on offer to encourage people to go green in order to reduce their own carbon emissions at both the state and national levels.

When it comes to any form of solar energy, what automatically comes to ones mind are cost efficiency and convenience. That is why many homes in the US use solar powered equipment in their household as much as possible. Thanks to technological evolution, solar powered equipments take a central place in many people’s lives today. It has also led to indoor solar lights to be used in households, especially in areas that are howered with sunlight all throughout the year. Want to learn more about true renewable power?

Indoor solar lights not only help you save electricity, but it also help reduce the green house effect, helping the envitonment. According to statistics from the Energy Star website, if US households switch on to indoor solar lights, $600 million can be saved from energy costs, anually.

Switching to Indoor Solar Lights is extremely efficient procedure where the constant replacement of light bulbs is not a necessity within your home. In order to make this change however it is essential to install a solar panel system large enough for your home in order to receive and store solar energy to be utilized later on. Indoor Solar Lights can ideally be used in extra rooms such as the garage, storage room or even barns as there is no need for wiring and is extremely convenient. True renewable power is here!

Using Indoor Solar Lights for your entire home though is not recommended due to the unpredictable nature of sunlight within the vicinity. Another reason why indoor solar lights are not suitable for your household is because they are not as bright as electrically powered ones. If you live in a country where seasonal changes take place, indoor solar lights may not be the ideal solution for the entire home. Indoor solar lights are usually available for usage during both night and day because energy that gets accumulated during the day gets used up during the night. Although indoor solar lights are a good replacement for electrically powered lights, it is still not a total reliable solution. Therefore, indoor solar light should not be used in the entire house. Totally green energy for your home – are you ready?

Solar powered cars are electric vehicles which are powered by solar energy that is obtained from solar panels on the surface of the car. Basically, photovoltaic cells then convert the sun’s energy directly into electrical energy. Although solar powered cars can travel for short distances without exposure to the sun they still are not a very practical form of transportation.

Solar powered cars were first built by universities and manufacturers, and development continues on solar cell design and car power supply requirements such as heater or air-conditioning fans.

Like solar power for the home the solar array on solar powered cars consists of hundreds of photovoltaic cells converting sunlight into electricity. Cars, unlike many other objects that use solar energy, can use a variety of solar cell technologies, which most often involves polycrystalline silicon, monocrystalline silicon, and gallium arsenide. Solar cars usually have incredibly distinctive shapes, as designers aim to minimize drag, maximize the exposure to the sun, minimize weight and still make the vehicles as safe as possible.

The Advantages And Disadvantages

There are both advantages and disadvantages to solar cars, and all of these should be taken carefully and thoughtfully into consideration. Some of the advantages include, for one, that of safety and convenience, for instance there are batteries available on most solar cars which store electrical energy that is to be used later by the electric motor when the demand for electric power exceeds that of the output of the onboard generating device.

Another advantage involves efficiency, as all solar cars can produce their full power at any speed, unlike normal cars. Another prime advantage of solar cars is that they are positive in regards to the economy. This is because an electric motor and an electric generator are the same device, basically, and electrical current is fed into such a device, causing it to act as a motor and, thus, creates mechanical power.

There are certain disadvantages, too, such as, most of the solar cars available do not have the power or speed of many of the regularly available cars and vehicles and, as well, the battery on the solar car may have to be used far too frequently depending on the weather, for instance if it is dark out for several days, you will have to rely on the battery of the car in order to make it work. This can seem as a hassle to many people, which is a large explanation towards why solar cars still aren’t that popular today.

Forecasts from the US Energy Information Administration put global demand for energy increasing by 54% over the next 20 years.   The EIA long-term energy forecast also predicts that world electricity demand will nearly double by 2025. 
Most of the world’s energy is produced from fossil fuels such as oil, coal and gas.They release energy during burning, but also simultaneously release carbon dioxide into the air.Not only are these conventional sources finite, they also result in harmful emissions when being burnt, so we need to develop more environmentally friendly and renewable energy sources like solar, wind, water and geothermal.   
The amount of energy from sun that reaches the surface of the earth is 6 000 times greater than that which is used on earth.Since ancient times, solar energy has been used to meet some of the world’s energy needs, but with increasing awareness of environmental issues, solar power has come to the fore.
Traditional fossil fuels such as coal, oil and natural gas are being replaced by renewable energy sources such as solar power, which is mainly used for heating water and electricity.  
From massive skycrapers and gigantic sports stadiums to remote farms and regular homes in the surburbs, solar power is a clean, cost-effective and environmentally friendly solution.For eg, the newly finished 55 000 seater stadium in Taiwan is the world’s first stadium to use solar energy technology to produce power.The 19-hectare stadium was built for the World Games in 2009 and will generate enough energy for its 3 300 lights and two gigantic TV screens through the 8 844 solar panels on its roof.  
That is solar power on a massive level.On a far smaller – but no less important – scale, solar energy provides a cost-effective and low maintenance option for domestic households.
According to Perth solar power specialists, Solar My World, homeowners will add value to their properties, make a positive contribution to the environment and reduce their power bills by installing solar panels on their properties.For Perth property owners, there are two solar power options available – grid connect and off-grid solar power.
A grid connect system is usually installed in areas that are more built-up and will supply solar power to a household through an inverter.  If the system provides more energy than the property requires, the surplus can be diverted and ‘sold’ to the electricity grid.  The other system type is a standalone system using a battery bank to store energy.This system is more common in remote outlying areas where people have no or restricted access to traditional power sources.  
Solar power systems are versatile and can be designed for both AC and DC and can always be expanded to meet changing needs.
Energy accounts for the largest single contribution to global greenhouse gas emissions and there is growing awareness and urgency for humans to preserve the environment by looking for their own ways of reducing CO2 emissions.By using solar energy technology to generate power, the new Taiwanese stadium alluded to earlier in this article, will prevent 660 tons of carbon emissions each year.  By making a simple decision to install solar power in our domestic locations, we could all have the energy to save the world.

Solar powered cars are normally electric vehicles, where the electricity is generated by solar panels on the car catching solar energy.

Albert Einstein’s theories on the photoelectric effect – involving the generation of electricity through solar cells – won him the 1921 Nobel Prize in Physics.
In the 1950s, Bell Laboratories (now known as AT & T Laboratories) developed the first silicon solar cell which could generate a measurable electric current.It was the first time that something had been developed that could convert sufficient amounts of the sun’s energy to power ordinary electrical appliances.
The first practical application of photovoltaic silicon solar cells also came in the 1950s with the launch of the satellite, Vanguard 1.The first solar powered aircraft flew across the channel from France to England in 1981 under power from its sixteen thousand solar cells which gave off 3 000W of power.

Environmental concerns have also escalated the search for renewable energy resources such as solar power, wind power and geothermal power.While the world has moved on significantly from the very early days of solar energy, the basic theory of solar power as a viable alternative to fossil fuels remains intact.

When we hear about how thinking globally and acting locally, power is often not at the forefront of our minds. But perhaps it should be. The environmental impact of transporting electricity is easily as taxing on the world climate as transporting hard consumer goods can be. Transporting power creates a direct waste of that power, creating a larger carbon footprint.

An immediate question springs to mind, however. Isn’t all power produced at least somewhat locally? In short, it is. However, we have narrow down what we consider local. If your power is produced 100 miles away, that’s not terribly far in today’s world, but some of the electricity will be lost over that 100 miles. If the power is produced on your roof or in your backyard, none of it will be lost (or at least very little of it).

For a moment, consider the factors at play in producing power. First, one has to consider the source of the power (i.e. coal, solar, wind, etc.), then where it’s made (in a plant, in your backyard, etc.), then how far it has to travel (NY to CA or from the source to your breaker box). Something many don’t realize is that electricity degrades as it travels. While our technologies for creating power have advanced rapidly, our technologies for transporting and storing power have not. Some new developments, such as hydrogen fuel cells, have promise, but the kinks are not all worked out yet.

To truly create green power, that power needs to be created close to home. There is a set of factors at play: 1. This will rely on a local resource (i.e. creating solar power in Phoenix rather than Seattle); 2. This will require little transport, and therefore less degradation of the power; 3. Ultimately, less power will have to be created for the same outcome.

As it becomes easier and easier to build solar cells and wind turbines (not to mention micro-hydro systems) at home, it is worth considering ones environmental impact. The benefits are numerous- it save the environment, saves your power bills, and could even make you money (think tax breaks or even selling power back to the power company). Numerous resources are available to the home builder of green power, allowing it to be used in many different environments (rural, urban, suburban). Between the guides available today, the necessity of saving the climate, the potential financial savings, and the long-term satisfaction of building green power, building your own home power system is more attractive than ever.

While solar power practices have become more common for residential and commercial areas alike, the manufacturing and operational costs can be quite high, which is why a number of businesses are still using traditional forms of electrical power. Millions of dollars are spent on wind farms and solar energy fields every year in different parts of the world, and countries like Spain and India have witnessed significant success, largely due to the fact that weather conditions are favorable for ‘green energy.

In the years to come, entrepreneur companies like Nanosolar are leading the way to lower costs and solar power for everyone. The company is pioneering new materials and manufacturing techniques to make solar more cost effective. Nanosolar Inc. reduced overall production costs by more than $2 per watt, which is the reason why many construction companies are contracting with the corporation in order to build environmentally-safe locations that will last for years.  This is making a home solar power kits more attractive as time goes on.

The technology behind solar power is also moving into solar arrays. Leading scientists are looking into these to see how effective they would be for everyday use. Solar arrays are a series of solar panels that are constructed outside of the Earth’s atmosphere and placed into orbit. The power generated is then beamed through space down to earth where a receptor grabs it.

Contacting your local construction companies or contractors to get examples of solar power designs will help you to learn more about this form of energy, and will allow you to see some examples of how ‘green’ construction can benefit the planet.  Many people, once they do the research, are looking to diy home solar power kits as a way to get into the solar power game. One of the best ways to learn about solar is to actually build a solar power system yourself from easy to follow plans, such as a diy solar power kit, whether from the internet or another source.
