Renewable energy is energy that is derived from natural resources such as sunlight, wind, rain, tides, and geothermal heat. These are naturally replenished as opposed to non-renewable energy such as fossil fuels.

Mesh corrugatedThough most renewable energy projects are large scale, they can be made smaller. These are residential and rural off-grid applications where renewable energy is crucial. Some of these technologies, including wind power devices such as turbines, are often considered to be quite beautiful and are a subject of many pieces of art.

The three main energy sources are the sun, wind, and water. Most renewable energy sources are powered by the sun. The amount of heat radiation into space is equal to incoming solar radiation, which results in the level of energy that is the Earth’s climate. The hydrosphere of water absorbs a large percentage of the incoming radiation, and wave motions then play a role in the process of transferring mechanical energy between the atmosphere and the ocean. These things all contribute to renewable energy. This energy is instantly replenished as it is used.

Wind generators range from around 600 kW to 5MW of rated power. Wind turbines are most common for commercial use. Areas where winds are strong and constant are preferred sites. These include high altitude sites and offshore sites. Because wind speed is not constant, the annual energy production is not as large as other generators. Globally, long-technical potential of wind energy is believed to be five times the total of current globe-wide wind production. This would be 40 times the current electricity demand.

Water power, also known as hydropower, is energy in the form of water. This can be found in things as minor as a slow flowing stream of water. Hydroelectricity is a term used for large-scale hydropower generators. Micro-hydro systems can produce up to 100 kW of power. These are used in water-rich areas. Damless hydro systems are able to derive kinetic energy from rivers and oceans without using a dam.

Ocean energy is another popular renewable energy source which harnesses the power of the sea. With the use of current power and ocean thermal energy conversion, an immense amount of energy is collected. Tidal and wave power are also an energy system used within ocean energy harnessing.

Solar energy is the most commonly known renewable form of energy. It can be used in both residential and commercial situations. With the use of photovoltaic solar cells, it is possible to collect enough energy for 75%-100% of residential needs. It is possible to collect electrical energy as well as radiant energy which allows for heating of water, for the generation of cool air, and more. Solar energy can also be used for floor-coil heating or to heat swimming pools.

Conventional fossil fuels are, by their nature, finite and will ultimately be depleted. Integrating renewable energy sources into our power supply reduces greenhouse emissions today and provides a path for the transition to a world without fossil fuels tomorrow.

Renewable energy
Publisher: Gareth Hoyle Our generation is probably more aware of the environment and the affect that our actions have on it. We are aware that we need to pay better attention to what we do and the effect that this can have on the environment. Renewable Energy
Publisher: Erin Hunt Renewable Energy is energy derived from resources that are regenerative or for all practical purposes cannot be depleted. Sources such the sun and the wind, can never be exhausted and therefore called renewable. They cause fewer emissions and are available locally. Their use can, to a large extent, reduce chemical, radioactive and thermal pollution. They are a viable source of clean and limitless energy. These are the non-conventional sources of energy. Most of the renewable sources of energy are fairly non-polluting and considered clean except for biomass, a renewable source, is a major polluter indoors. Renewable Energy – Energy Sources For Renewable Energy
Publisher: Don P We are at a time that we have to create our own renewable energy, if we are going to survive. And how lucky we are that there are different types of energy sources to choose from. What makes it even better, is that we can build our own energy products for ourselves. What are Renewable Energy Sources
Publisher: AmaKson Forms of Renewable Energy We should start by answering the question. What is renewable energy? It is a form of energy, of which replaces itself naturally. Renewable energy resources help us to reduce the expensive energy sources we have grown to depend on. Sometimes there is controversy as to whether a renewable energy source is good or bad for the environment, but that is for another article. T Rural Electric Renewable Energy – DIY Renewable Energy
Publisher: Josh Brentwood The most popular forms of rural electric renewable energy in the world today are both wind and solar power. You can build your own electric generators out of materials found in your local hardware store. Federal Renewable Energy Incentives

Publisher: Jas Williams From environmental dangers to higher costs with electricity, are several that are questioning the alternatives for keeping the lights on without burning the same amount of fuels. One of the main concepts that is becoming known to others is the use of renewable energy. Renewable Energy Alert
Publisher: Alexis Jameson Most things in life require energy in order to function. This energy can come from various different sources, some of which are renewable and some of which are not. In recent years there has been much talk about renewable energy and the positive impact that is has. So why should you care about renewable energy? Renewable Energy Development
Publisher: Ben Tan It should seem clear by now that finding non-polluting energy isn’t just a nice thing to do, but is the act of a species aware of its power to really foul things up. As a species we are currently “fouling the nest.” Self-preservation should be kicking in now. The form it clearly must take is a move to stop burning things for power. Renewable Energy Fuels
Publisher: Mark P Brown Non-renewable resources are on their way to depletion and the mighty increase in energy demand is worsening the situation for the future generations. As the ratio between the population and the resources keeps on increasing day by day, scientists are forced to focus attention on renewable energy as the alternate means of fuel. There are many reasons for us to discover and apply alternate fuel ideas to our lives; starting from the rapid decrease of natural fuel reserves, we have coal and petroleum products giving harmful fumes adding to the mess of pollution and giving way to the issue of global All rights reserved.
