So that we are able to all save money and conserve the environment, would you be enthusiastic about sustainable energy sources? If so, due to the fact solar energy and wind energy are certainly the way of the future, you are without doubt interested in solar energy as well as wind energy. If we invest in solar energy and also wind energy, we can create more jobs, and we can produce cleaner ways to power the globe, which will be great for our environment and generations to come. If you would like more info about solar energy and wind energy, this is definitely the right spot for you. In this post, we are going to talk about a bit about wind energy along with solar energy.

So that you can have a better knowledge of the exact manner in which it really works, let’s start by speaking about solar energy. Solar energy is merely energy that is harnessed from the energy of the sun. Because it is never ending and it is clean, it is possible to realize why this form of energy is a great idea.

Solar energy has been made use of for many, many years in many other ways. In order to grow vegetables and numerous plants, solar energy is used for such things as greenhouses. Solar energy could also be used to heat water, for water treatment, for heating, cooling, as well as ventilation, cooking, solar power, and also solar-charged vehicles. Solar energy can be used for virtually any sort of energy that we need, and it’s also one of the most beneficial resources that we have because of this. To ensure that we can utilize this wonderful resource, investing in solar energy more in the future a very good idea.

Since this is additionally a very beneficial thing for us to go over, we have to consider wind energy. Naturally, wind is an abundant source of energy that we could easily make use of, and it currently has been used in a lot of parts of the country along with the world. The energy that the wind produces is harnessed through devices called wind turbines. The turbines assist to turn the kinetic energy which is produced by the wind into mechanical energy that can be used for many reasons.

Wind energy has been utilized for many, many years also with devices just like windmills, which convert the energy of the wind into rotational power. Additionally, to propel them forward and to travel across the sea, sailboats are making use of the energy that the wind produces. We are going to definitely have a better as well as brighter future if we invest more money and time into building better ways to make use of this source as wind energy is another clean and abundant source of energy.

In much cleaner ways than oil, coal, or natural gas, both solar energy and wind energy may be used. Now that you have read this brief article, hopefully, you’ve got a better knowledge of these two beneficial energy sources and you will be a bit more advised.

Trying to find details on the wind power?  If so you’ve come to a good option.  Click on your links on this page and you’ll get all the information you may need on solar energy.

A Combination Solar Wind Power Generation System

January 9th, 2011

Finding alternative sources for power generation is on everyone’s mind and with the cost of using fossil fuels continuing to climb other forms of power is growing in popularity. While some parts of the country have an abundance of sunshine and others never lack for wind, a combination solar wind power generation systems are becoming more useful.The details were provided by a dealer of Rheem who also delt with solar power NZ as well as inverter in Auckland.

Depending on which part of the country in which you live, solar panels can be used for the efficient generation of electrical power. In other parts of the country, wind power can be used on a regular basis, but when the winds do not blow and the sun does not shine, electricity may be scarce. A combination solar wind power generation system may be an alternative that can work where you live.

Either method uses batteries to store the power generated, and the use of a power inverter can provide as much as 240 volts of power to your residence. When the batteries are fully charged, the charging system automatically shuts off, but when the charge in the batteries is depleted to a pre-set voltage, the charger turns back on, keeping the batteries with enough power from the combination solar wind power grid.

While both systems send generated power to the charging unit, they both may not run at the same time due to weather conditions. Some places in the United States such as Kitty Hawk, North Carolina have strong winds throughout the entire year. That’s why the Wright brothers chose it to test their airplane. Using a combination solar wind power system would be more useful in places where the wind does not blow everyday.

Residents in the extreme northern part of North America may find a combination solar wind power system beneficial, especially in places with only six months of daylight. During the dark part of their year, they could not generate electricity without a combination solar wind power system.

Residences where electrical use is virtually non-existent after dark could probably store enough power generated during the day for nighttime use. However, if the charge in the batter diminishes after dark, a combination solar wind power unit would switch to wind power and keep the batteries adequately charged.

By using a combination solar wind power generating system, the need for gas or diesel generators is removed and even those living in the remote corners of the world can have their own source of electrical power without the need of fossil fuel.

MODERN LESSONS FROM ANCIENT TIMES

November 2nd, 2009

Solar power has been around since the Seventh Century BC. 
In ancient Egypt, bricks for construction were made from shaping a mixture of mud and straw into blocks and baking it in the sun.Ancient Greeks and Romans recognised the benefits of what we now call passive solar design – using architecture to maximise the sun’s capacity to heat and light indoor spaces. 
In order to get the maximum benefit from the winter sun, they made sure their buildings were orientated towards the sun.At the same time, they were able to cut down on firewood which was scarce, displaying a very early switch from fossil fuels to 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.
Solar energy was also used as a weapon of war as early as 200 BC with the ancient Greeks using bronze shields to direct the sun’s rays onto the Roman’s wooden ships, setting fire to them.  Some native American cultures built their homes against the sides of rocky cliffs to benefit from the natural storage of heat harnessed 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.
Mathematician Auguste Mouchout continued the French nation’s interest in solar power, and invented the first active solar motor and a solar powered steam engine.  Both inventions failed due to high production costs.
Scientists all over the world were experimenting with solar energy.  In 1876, William Grylls Adams discovered that selenium produced electricity when exposed to light, without the need for heat or moving parts. 
In 1921, Albert Einstein who is better known for his Theory of Relativity, was awarded the Nobel Prize in Physics for his theories on the photoelectric effect.
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 cell capable of converting enough of the sun’s energy into power to run everyday electrical appliances.
The launch of the satellite, Vanguard 1 in the fifties marked the first practical application of photovoltaic solar cells.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.
The Arab Oil Embargo in 1973/4 forced western economies to rethink solar energy research as a means of reducing their dependence on oil.A large number of new applications was made possible after Dr Elliot Berman designed a less expensive solar cell in the 1970s. 
Concern for the environment has been a major driver of research into renewable energy sources, including solar power, geothermal and wind 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.
