There seems to be a lot of confusion between renewable energy technology and alternate energy technology. Alternate energy refers to any form of usable energy that can replace the energy based on fuels. Alternate energy is normally without the negative or harmful consequences that are seen with fuel based energy sources. Whereas renewable energy technology is something where energy is renewed on a continuous basis as you use it. For example solar power generator and wind power turbines.

It is a fact that fossil fuels are not going to last for long. Realizing this and preparing to handle energy requirements for the future is the right strategy to adopt. And renewable energy technology offers you several ways to do this with a little upfront investment and very little ongoing maintenance. With the prices of silicon wafer dropping continuously electronic components and devices will continue to get cheaper only.

Also the information guides and videos that come along with these guides makes the process of building your own renewable energy technology based projects extremely easy and simple. These guides cover everything like design, procurement of parts, bill of material, assembly and installation. Even a novice can start building a solar energy or wind power system without spending larges amount of money.

Since renewable energy technology is based on resources that are naturally available, you don’t have any constraints in terms of availability. And most of the projects based on these technologies don’t pollute the environment and they do not produce any green house gasses also.

However before you start a new project it is important to do a few things properly. First is the survey of the place you live to make sure that you have the renewable resource like sunlight, wind or waterpower that can drive the project. Secondly you need to calculate your energy requirements and accordingly buy components and devices that can help you generate the correct amount of energy. The third factor is to decide how you want to mix and match renewable energy technology with some of the existing energy technologies based on fossil fuels.

Over a period of time you can scale up the renewable energy technology based projects to deliver more energy and reduce your dependence on fossil fuel based technologies.

As gas and energy prices continue to rise, more of us are looking for alternative ways to power our homes and produce electricity.

Green Renewable Energy is energy that is generated from natural resources that can be replenished is a short time and have little or no impact on the earth.

There are many sources of green renewable energy

Biomass is organic material made from plants and animals. Biomass is a renewable energy source because we can always grow more trees and crops, and waste will always exist. Some examples of biomass fuels are wood, crops, manure, and some garbage.

Hydropower is the use of water to generate electricity and power. Some people regard hydropower as the ideal fuel for electricity generation because, unlike the nonrenewable fuels used to generate electricity, it is almost free, there are no waste products, and hydropower does not pollute the water or the air.

Geothermal is heat from within the earth. We can use the steam and hot water produced inside the earth to heat buildings or generate electricity. Geothermal energy is a renewable energy source because the water is replenished by rainfall and the heat is continuously produced inside the earth.

Solar energy is the conversion of sunlight into electricity. A photovoltaic cell, commonly called a solar cell or PV, is the technology used to convert solar energy directly into electrical power.

Wind energy is mainly used to generate electricity. Wind is called a renewable energy source because the wind will blow as long as the sun shines.

Some of these sources, such as solar energy and wind energy we can easily incorporate into our daily lives. You may now even use solar powered landscape lighting or other similar devices.

Let us first understand what energy is. We need energy to move about and work. We need healthy food to get that energy. The plants convert the sunlight and water into energy to grow. On the other hand, we use energy to travel from place to place in a car or in a plane, and it is this energy that we use to light and heat our homes. We use the energy stored in fuels, when gasoline is used to power the car. The engine in the car transforms energy in fuel to work on the wheels, for the car to move.

The energy that we put to use every day comes from the Earth’s natural resources, and these resources could be classified into two categories; renewable and non-renewable energy. It is the energy that we can use over and over again, which we call renewable energy, for example wood. We get more and more wood by growing trees, the source is far from running out at present. But, as far as gasoline is concerned, the resource has already started to deplete, and the energy that we get from fuel is a non-renewable energy.

The solar power is now being used to generate the much wanted electricity using the photovoltaic energy, converting the Sun’s rays to generate electric power. These photo cells are devices, made from silicon alloys, which produce electric energy when the Sun light falls on it. The Sun’s rays are composed of photons, which contain various degree of energy, and this energy corresponds to the different wave-lengths of the solar spectrum. When the sunlight strikes a photocell, the photons falling on it either gets absorbed, reflected, or pass through. It is those photons that get absorbed produces electricity. As the Sun’s rays strike the surface of the photovoltaic cell, electron migration takes place, and this creates imbalance of charge, which appears as a voltage potential at the output. A large array of thee photovoltaic cells are used to produce enough electricity to light up a small house. The Sun light is therefore a renewable energy source, which could be harnessed to provide power.

India’s total installation of power capacity is a little over 124,000 MW and out of that 60% is coal based, with hydro at 25%, and the rest are coming from gas and nuclear energy. Power shortfall has been estimated at 11% of the total energy, and 15% of the peak capacity requirements. These are likely to increase. It has been recently announced that the country would be facing a sudden power shortage of 70,000 MW, and several measures are being taken by the Indian Government to avert the shortfall. However, the power sector planning estimates, that another 10,000 MW of capacity will be required by the country in the in the near future, with the requirement of a further 10,000 MW in the next 10 years. There are environmental concerns about coal-base power plants, related to its emissions of particulate matters, sulfur dioxide, nitrous oxide, carbon dioxide, methane and other gases. As regards the other alternative, Hydro-power plants can lead to degradation of soil, erosion, destruction of forest, wildlife displacement, and most important of all displacement of human habitats. The Indian Government has put the use of renewable energy in its top priority list to encounter the shortfalls envisaged.

Being a tropical and sub-tropical region, most part of the country experiences a clear sunny weather, over 250 to 300 days a year. This is comparable to the annual global radiation, which varies from 1600 to 2200 kWh/sq.m, which provides an equivalent energy potential of about 6,000 million GWh per year. According to the report maintained by the India Meteorological Department, the state of Rajasthan and Gujarat receives the highest annual global radiation, and with a large part of the land in the state of Rajasthan being barren and scarcely populated, it has become a suitable site for large central power stations based on solar energy.

In the sunny state of Rajasthan, the Indian Government is about to complete a huge new power station using hybrid systems. This fossil fuel/solar hybrid power plant is poised to generate a huge 140 megawatts of electric power, out of which 40 megawatt will be produced from a large array of solar parabolic troughs. The technology, which is much more cost effective than photovoltaic cells, uses large parabolic mirrors to focus the sunlight to heat a thermal media, like, gas or steam, which in turn drives a turbine generator. The project cost runs to about $1 million per megawatt and is still considered to be cheaper than the others.

In setting up a solar thermal plant in the state of Rajasthan, there are a few points to be proved, and these include:

- The operational viability of the technology used.

- Development of solar power energy for an expected significant reduction in operating costs.

- Contribute efficiently towards clean energy, and help to reduce greenhouse effect in the long run.

The operational viability of the solar energy thermal power plant is hoped to be demonstrated through commercial power sales and delivery arrangements with the grid. The technical development of the system is planned to be achieved through technical assistance and training. The power plant is a step forward to a long term program, for promoting the objective focused on climate change.

Making maximum use of renewable energy sources is not only a good way to save money, but it also helps in making the environment better.Renewble energy sources like solar, wind, water and geothermal energy are considered to be best environmental friendly energy sources that do not discharge toxic substances in the environment like Fossil Fuels and Nuclear Energy creates. These renewable Sources are becoming a viable alternative to burning Coal, Oil and Gas. They have become a perfect medium to render electricity along with heating and cooling our home and work area.

Complimenting the energy resources some experts developed ‘smart fridges’. These are capable to assert an average temperature and also determine the power consumption from renewable energy generators like solar panes or wind turbines. A solar panel creates ample amount of energy which is able to keep the content of fridge cold at night. Another benefit is that the usage of electricity is minimal so the need to construct more power stations is minimized.

Additionally, may the usage of Solar heating panel at your home be the perfect idea. These panels are helpful in maintaining the overall energy usage of your home and lower your monthly electricity bill. Moreover, you can also opt for a Solar Heating Device outside your home area so that you are less dependent on heating oil, gas or electricity. If you think that installing a range of renewable sources like solar panels, solar heating system, solar water tank and wind turbines are costly then probably you are wrong. These renewable technologies are available at minimal costs and save a huge amount of your monthly bills.

Global climate change is constantly affecting all of us. It can be controlled with usage of renewable sources; these sources will also provide cost advantages over fossil fuels. Presently, scientists are finding ways to make the most of renewable resources and developing effective measures to make renewable resources more widespread and easier to use. The concept of renewable energy is as old as man kind – think of windmills back in the Netherlands or sail boats that use the power of the wind. Still, the re-invention of renewable energy is not as popular as it should be. Renewable resources can be utilized by anyone, anywhere. The only requirement is knowledge and means of utilizing the technology.

It’s time for you to begin investing in the renewable energy sources, the more you are be informed about the technology the more it will help in making correct choices.

Renewable energy is important for many reasons. Mainly because renewable forms of energy are not harmful to the environment. They are typically safe for the earth, making them much cleaner than coal or oil. Also, renewable energy sources will not become scarce or be in danger of exhausted supply as many believe will happen with fossil fuels.

After the scare at Chernobyl concerning nuclear energy, it seems that research for alternative sources of energy was curtailed for many years. However, because of increasing cost of fossil fuels, and diminishing resources, there has been increasing research for new alternatives.

There are many different types of renewable energy, including solar, wind, and water. A decided plus is that there is nothing produced by these sources of energy that could harm the environment.

Solar energy refers to power from the sun. I often think about the old Aesop Fable where the wind and sun debated about which was more powerful. They decided to do an experiment to see which of them could force a traveler to remove his coat the quickest. The wind blew furiously, but the harder it blew the tighter the man held onto his coat. Then it was the sun’s turn and it shone brightly for just a short time before the man decided to remove his coat. So they agreed that the sun was more powerful. That is a humorous story, because it really didn’t prove anything about which was more powerful. Both are very powerful and useful forms of energy. And both have been proven to be great for heating homes and providing electrical energy.

Many industries in our country used windmills and water power from farming and flour mills to the lumber industry. With the discovery of electricity those methods were largely abandoned in our country, but they are still used in many countries today.

We are again realizing that these forms of energy are worth developing. Commercially, systems are being promoted for the homeowner, but many are priced out of reach for the ordinary citizen. The good news is that it is now possible to generate your own electrical power or heating system and to build the generator yourself. In my neighborhood there are increasing numbers of solar panels on rooftops.

You may want to investigate these alternative methods for your own use not only to save the environment, but to reduce your cost of living in these uncertain times.

Large wind turbines are a good source of renewable and relatively clean energy. They have captured the attention of many environmental groups lately as a very realistic new alternative to currently used energy production techniques. Let’s see how they compare to current energy production methods.

The way we produce most of our electricity these days can hardly be called environmentally friendly. Coal fueled power generators belch thousands of pounds of pollutants into the air every year. The mining necessary to fuel one of these stations can devastate vast areas of land, transforming it into barren wasteland. Nuclear power plants produce cleaner energy, but have the potential of creating a much bigger disaster if nuclear meltdown should occur. Even hydroelectric systems cause damage to the surrounding eco system with their dams and sluice gates.

With the “green” movement in recent years, people have turned their attention to more modern approaches to energy production. These days we have set our sights on clean, renewable energy sources. Let’s look at how the different sustainable energy sources stack up.

Some countries in Europe have been developing exciting new ways to harness the energy of the tides. These tidal stations work quite well, but the technology is in its infancy. There are also concerns over the effects it may have on habitat. Although wave energy might be a viable option in the future, there is still the obvious disadvantage that this technology relies completely on proximity to a tidal body of water. Inland areas cannot take advantage of this type of energy collection.

Solar panels are probably one of the first things people think of when it comes to renewable energy. These big, heavy, expensive solar panels rely on delicate photovoltaic cells that capture a very minimal amount of energy. The ground area necessary for substantial energy generation can be immense. In order for solar panels to produce sufficient energy, the panels have to be spread out across a wide area, and this can disrupt many animal habitats and plant life. The cost to benefit ratio of this energy method is low, making it a poor option.

Something like a windmill doesn’t require as much space to produce energy. They can be put on the tops of skyscrapers, for instance. They don’t fail if the sun is behind a cloud, and they won’t break easily. They can quickly be adjusted to face the optimal direction for wind energy production, unlike photovoltaic arrays which are typically static.

Windmill technology is extremely old, and we have worked with it for generations in various ways. The basic physical premise behind the machine is well understood, and has not changed much in centuries. They are also able to be used anywhere there may be substantial air currents, and do not require a body of water.

If these things were used at a building specific level, a great deal of the power needs of a city could be met. With generating vanes atop each massive office building, the skyscrapers could at least be able to run their own elevators and lights.

As we move toward cleaner and more renewable energy sources to meet our ever increasing power needs, wind turbines are beginning to stand out as some of the better solutions. With a relatively cheaper price tag and a smaller environmental footprint than its closest alternatives, this may very well be the technology to get excited about if you are interested in the future of our energy supply.

The world currently relies heavily on nonrenewable sources such as coal, oil and natural for its energy. These energy sources are nonrenewable, which will eventually dwindle and causing environmental damages that are too expensive to be recovered. In contract, renewable energy resources will never run out because they can be re-produced endlessly. Moreover, they are clean and environmental friendly. With the technology improvement that significantly reduces the cost of using renewable resources to generate power, it will become the major energy solutions for the future. Let’s use review the five major sources of renewable energy, which the world is focusing on as the long-term energy strategy for future.

Energy Source #1: The Sun

The most common renewable energy source is either directly or indirectly from the sun. The energy from solar power can be directly be used for home uses. In fact, many of homemade renewable energy systems are built based on solar power system. The solar power has been widely uses as the alternative power source to generate electricity, and for hot water heating, solar cooling and to power a variety of home appliances.

Energy Source #2: The Wind

Besides the sun, the wind is another commonly use renewable energy source. The movement of wind is captured with the blades of wind turbines to be converted into electric energy, and then turn into electricity via transformers.

Energy Source #3: Biomass

Biomass is a renewable energy source, derived from living organisms such as plants, wood and waste. Although the Biomass has not been commonly used like the sun and the wind, mainly due to the complexity involved. However, scientists are making a good progress toward generating electricity and producing transportation fuels.

Energy Source #4: Hydrogen

Hydrogen is the most abundant element on the earth. It can be easily found many organic compounds, as well as water. Many of us may hear about the new concept of cars which run with water, is the one run on the Hydrogen power generated from water. Unfortunately, hydrogen does not occur naturally as gas, it always combined with other elements, such as it combines with oxygen (H2O) to form water. Therefore, it needs to be separated from other element first before it can be burned as fuel or transformed into electricity.

Energy Source #5: Hydropower

Hydropower is a power generated by taking advantage of gravity when water falls from one level to another. Usually, the kinetic energy of water is captured with water turbines and turns into electric energy to generate electricity.

Summary

The technology improvement has enabled the generation of power from renewable energy at lower cost then before. The above sources are the five major renewable, nonpolluting, and reliable energy sources.

Do you want to learn how you can use renewable electricity energy sources to run your house? Electricity consumption is at an all time high today and still rising, and this high demand is expected to cause energy prices to keep increasing in the near and long term future.

1. Is It Really Possible to Use Alternative Energy Sources to Run a Home?

It is now possible to build your own renewable energy system at home to produce your own electricity. This has helped me reduce my power bills by more than 80% and will also help reduce the amount of pollution into the atmosphere.

2. Solar Electricity Energy Sources

Solar power from the sun can be harnessed by making your own solar panels on the roof. This is one of the best renewable energy sources. The electric power generated can be used to run many household appliances. You can choose to install a battery system to store excessive electricity for future use or sell it back to the grid for profit.

3. Using Wind Alternative Electricity Energy Sources

Wind energy has traditionally been harnessed by windmills to grind up grain. It is a great alternative to traditional fossil fuels as they are very energy efficient and readily available.

4. Why Use Alternative Electricity Energy Sources?

Many people still think that renewable energy systems are still just a fantasy, when in fact they are already in existence and in use at many households. Hopefully, renewable energy will be used on a large scale one day as this will reduce pollution and save up spendings on electricity.
