Renewable Energy Resources

The central renewable energy advantages are the very fact that they are renewable. We won’t ever run out of supplies of renewable energy.

Solar energy – the sun will permanently be there, and in abundance – the amount of solar electricity intercepted by the Earth each minute is bigger than the amount of power the world uses in fossil fuels every year.

Wind energy – the wind will always be present – The power in the winds that blow across the U. S. Yearly could generate more than 16 billion GJ of electricity – more than one and one-half times the electricity consumed in the United States In 2000.

Tidal energy – the moon which supplies the forces that causes the tides will always be present

Hydroelectric energy – unless there is a drastic variation in rain patterns, it will always be there

On the other hand, non-renewable resources like traditional fules are limited – our resources of them will run out in the end.

A second renewable energy advantage, is that renewable energy is environmentally friendly. The reason being since they don’t give off CO2, the largest contributor to global temperature rises, into the atmosphere.

Non-renewable resources like petrol discharge CO2 into the atmosphere when they are used for creating power. Additional renewables such as biofuels are carbon neutral – producing them uses about as much CO2 as using them produces.

Renewable energy resources can be re-used and are straightforward to discover. But the non-renewable sources can not be used again.

Today any one, can construct their own renewable electricity generators at home and enjoy the advantages of renewable energy. A number of plans and guides now exist to show you how to construct a wind mill out of pvc pipes or a solar cell out of basic reflective glass and all for very little cost. Consider these renewable energy advantages for making the easy and reasonable switch to natural electricity.

One small wind mill can make the equivalent amount of natural electricity that synthetic and fossil sources do while putting out 5000 tons of CO2 simultaneously. Scientists virtually collectively agree that once the larger population of the earth welcomes renewable energy, we’ll begin to see a fast reversal of the greenhouse effect.

It is the Future and Builds For a Better Future. Natural and renewable energy advantages outnumber the application of traditional fules, and eventually we will have no choice but to use these natural supplies. Limited sources of fuel are quickly lessening as the energy crisis continues to bear down on us.

It’s Cost Effective and is simply the largest and most well-liked of the clean energy advantages is that it’s extremely cost effective. In the beginning, the average homeowner spends about $2500 each year on their electricity bills alone. Think of not relying on the power company for that electricity and instead selling back any exess renewable energy which you manufacture but don’t use in a given month to the power company for a profit.

To end with, do not overlook the substantial and generous tax breaks that the government, particularly now under the Obama government, hands out each year to those who embrace clean, natural energy.embrace clean, natural energy.

Lots of individuals do not realise that it is possible to use renewable energy such as solar power and wind power to produce sufficient electricity so that you could save as much as 80% of your normal electricity costs, in fact in a number of cases it is even viable to produce so much electricity that your are able to sell it back to the power company.

In the following paragraphs, details of available alternative renewable energy resources will be discussed, together with reasons why it is important to look at your options, paying particular attention to the fact that the more people who consider alternative energies, the slower the extinction of fossil fuels.

As mentioned above, solar power is an excellent source of renewable energy which makes use of the sun to generate energy. Solar power is directly converted through radiation in the form of a solar PV system; other forms of solar power include solar hot water systems and solar water purification systems.

Presently there are thousands of homes using solar power to generate electricity, and as technology develops, prices reduce and use and approaches to alternative energy sources (such as implementing solar energy house plans into a new or current build), can become a realistic option for people who want to save money, reduce carbon emissions and use a clean green source of power.

Another alternative energy source comes from wind energy which is also increasingly being used by those people worried about the decline in fossil fuels and the rise in domestic utility bills. Recently there has been increased demand for the installation of wind energy systems in order to provide greener, cleaner living.

Contrary to popular belief, wind does not have to constantly blow to power homes with wind energy. As with solar energy, a huge benefit of wind power is that wind is clean, green and you can make it in your own back garden. Out of all the renewable energy resources available, wind power has the best potential for growth and development.

People living in remote places who have a good amount of land, find wind/ solar energy for their homes a viable option. This is because in some locations the national grid power is not available. Wind power is reliable and consistent. Other benefits include cost, it is not too expensive to install a system which works well when wind power is available,as a back up when wind is really not available, people at remote locations can use battery powered systems.

It doesn’t matter if you don’t live remotely, the opportunities for incorporating house renewable energy into your home are abundantly available, and installation of even small scale window power will generate at least 20 kilowatts of energy daily, enough to power most UK households.

The modern lifestyle depends tremendously on the use and existence of fossil fuels. With levels of these fuels constantly decreasing, we should act now to become less dependant on fossil fuels and more dependent on renewable energy sources.

The decreasing levels of fossil fuels isn’t the only reason why we should begin to use renewable energy. Pollution is becoming a huge problem in many countries around the world, especially the developing world. With carbon emissions at an all time high, air quality can be very low in some areas, this can lead to respiratory diseases and cancer.

The main reason to switch to cleaner energy production methods is the global warming aspect. The more carbon dioxide we pump into the atmosphere, the greater the effect becomes. We can’t just stop using fossil fuels thinking that global warming will go away, but we can slow down and dilute the effects of global warming through the wide spread use of renewable energy resources.

There are many natural energy sources out there, but you have to decide which method is best for you, as all of these sources depend on your current environment.

The installation of a solar panel or a wind turbine to boost every homes power supply would be an amazing step forward. Some governments are in the process of supplying solar panels to hundreds of households to test this method of energy saving.

A technology set to be very important in the future is geothermal energy. With geothermal energy, you are able to extract heat from within the earth and transform it either into a hot water system, or if there is plenty of this energy, a geothermal power plant. Huge amounts of money have been flowed into research of this method, especially in recent years, in order to make the current technology more effective.

So there we have the reasons why we should turn to renewable energy resources which are more than likely to play a very vital and important role in our future society.

An alternative energy resource, gaining much market share, is solar power. It is the one that is most well known every day. This involves the manufacturing of solar cells which gather and focus the sun’s energy, and translate it into electricity. In some, hot water can be produced from the sun. As with wind energy, solar energy creates absolutely zero pollution.

One of these renewable energy resources is solar energy. Solar PV cells continue to be manufactured that are often more energy efficient and less costly than previous models from a few years ago. Solar energy plants have been developed in in many nations. They are now more strategically placed in order to improve the national electricity grid. Over time, they are not causing environmental issues as previous placement of solar panels may have caused.

The following sections provide a summary overview of many other renewable energy sources being researched, developed, and deployed throughout the world.

Ocean current energy is discussed by governments and investors as having untapped energy generating potential. A ocean electricity generator in Europe has been in operation for a long time. It is thought to be a great accomplishment. The Irish and Scots are also running pilot facilities.

Hydroelectric power has been with us for a while. At current hydro dams, it is a clean generator of electricity. Because water and gravity is used, it is more effecient than a grid powered by natural gas. There are restrictions to the availability of the right places to set up a large dam. Many river based, or small and localized, hydro generators where created in recently due to this limitation.

Geothermal energy is extremely abundant. Since it lies directly beneath us, we only need drill just a few miles below the earth’s surface to find huge amounts of energy. This energy is produced by the heating of water, trapped in layers of rock, through the earth’s hot molten core. The water turns to steam, which is then used to drive turbines that generate electricity. Great amounts of research and development should be put into geothermal energy tapping.

Biodiesel energy is created out of the oils contained in plants. Most commonly, the retail stockpiles of bio-diesel have been created using rapeseed and sunflower oils. At the time of this writing, biodiesel is typically produced by agricultural corporations or those who want to experiment with renewable energy. Venture interest from companies across the World is on the rise. It burns much better than fossil fuel diesel.

Another renewable energy resource is solar generated electricity. Solar PV cells continue to be manufactured that are often more energy efficient and less costly than previous models from a few years ago. This involves the manufacturing of solar panels which gather and focus the sun’s energy, and translate it into electricity. In other cases, hot water can be produced from the sun. As with wind energy, solar energy creates absolutely zero pollution.

In modern western world the demand for energy has increased dramatically in the past century and it will grow even further and harder in the near future than ever before. The need for energy rises with upcoming markets that also need more energy. Energy is needed for cars, buses, and other means of transportation, but also to run our appliances and provides us light. Energy is also important for our safety. At night or in the dark a lot can be stolen without proper lightning. Energy is therefore needed for our development and safety.

The way we use energy today comes from knowledge that has it’s foundations in the past century and before. Great men like Newton and Philips have set the path for us today to make proper use of energy. The sources which we use for our energy demand are known as non-renewable energy resources. These sources will be discussed here in the article.

Definition of Non-Renewable Energy Resources

The name really explains it very well. Non-renewable energy resources are natural resources that cannot be recycled or re-grown. These natural resources are fossil fuels like coal, petroleum, and natural gas. It also includes mined resources such as the elements used in the production of electricity (uranium and plutonium, for instance). These resources replenish itself in a quicker rate.

Fossil fuels are very versatile. One of their functions is to generate electricity. In order to generate electricity, fossil fuels are burned through the process of combustion. The energy produced from the combustion process is used to power a turbine. The turbine is responsible for the conversion of energy produced from combusted fossil fuels into electricity.

Coal

Coal is one the most used fossil fuels. It is consider too be the most important energy source to produce electricity. The U.S. produces 50% of its energy supply through the combustion of coal. The coal itself is a brownish-black sedimentary rock which contains carbon and other assorted elements. It is extracted from the ground through underground mining or open-pit mining.

Natural Gas

Natural gas is also used to produce electricity. The electricity is produced through steam turbines and gas turbines. Because the gas contains methane the combustion emits less harmful gasses that have a negative effect on global warming. Thus natural gasses are better for the environment compared to petroleum and coal.

There is also another use for it and that is as fuel for cars. It is much cheaper that gasoline and produces less harmful gasses. The disadvantage of running your car on natural gas is that you need more fuel compared to gasoline and the car needs more maintenance. In countries like Argentina, Brazil, Pakistan, Italy, The Netherlands and India it is used as a fuel for cars.

Crude oil

This fuel is the most talk about for the past year(s). The prices for crude oil have gone through the roof and will be rising even more. The demand is increasing while there is less crude oil available. The term black gold is now more applicable than ever before.
The oil itself is very think in consistency and has a dark brown or greenish colour characteristic. It is a complex mixture of different hydrocarbons.
Crude oil or petroleum has various uses. It can be used as fuel or cars and different industrial machines. It is also used as a raw material for products like plastics, solvents, fertilizers and pesticides.
Although the need for crude oil is high and the demand is rising the available crude oil is decreasing. That leaves us no other option than to look for alternatives.

Non-renewable energy plays a very important role in our daily lives. Non-renewable energy will be needed today and in the future. Because this energy source cannot be recycled or re-grown the reserves are limited. The consequences of the shortages of fossil fuels are experienced today and tomorrow. We will need to use these fossil fuels wisely and will need to shift our focus to other renewable energy source. These are the sources that we need to focus on today and years to come.

Renewable energy is not a new concept. While it may appear to be a rather fashionable topic of conversation in certain circles, renewable energy initiatives have been with us since the dawn of man. There is some debate about the accepted definition of renewable energy, but it can be loosely defined as a form of energy that is essentially inexhaustible. Furthermore, the resource is continually replenished by various natural processes identifiable in the natural world.

One key distinction to make when discussing the concept of renewable energy is that of sustainability. One could make the argument that, in the long term, fossil fuels are a renewable energy resource. While the logic stands on its own, this is a failed notion. The central difference between fossil fuels and other forms of renewable energy is that fossil fuels are being depleted at a rate faster than they can be replenished. For this reason, fossil fuels cannot be considered truly renewable. They are simply not sustainable, due to the accelerated rate of consumption.

Some of the more popular renewable energy resources include sunshine, water, and wind. Solar energy refers to the energy that is collected from sunlight. This form of energy is captured using a photovoltaic array, more commonly known as a solar panel. The solar radiation is captured by the photovoltaic array and converted to direct current (DC) electricity. From there, the direct current electricity must be converted to alternating current (AC) for use in most applications. The converted electricity is then stored in a battery for use at a later date.

There are also various forms of energy that exist in water. One of the most commonly acknowledged is that of hydroelectric energy, but there are a number of others including tidal power and ocean thermal energy conversion. Hydroelectric energy generally employs the use of a dam, wherein the energy of the water flow is captured and used to power a turbine. The turbine then generates a supplementary form of electricity. Tidal power attempts to make use of the natural energy potential of tidal activity in the oceans and seas. In simple terms, the high tide is captured and fed through a turbine to generate electricity. Ocean thermal energy conversion attempts to exploit the variances in water temperature, from the warmer surface water to the cooler deep water, resulting in a cyclic heat engine.

Wind power is one of the oldest accepted forms of renewable energy. It has been used for centuries as a source of power, dating back to the creation of the sailboat. The innate potential of wind power was realized a number of years later in the form of a wind mill. In this instance, the kinetic energy of wind is used to drive a turbine which, in turn, generates electricity. Wind energy possesses immense potential for sustainable energy generation, and a number of large-scale development projects are currently underway throughout the world.

One of the greatest challenges facing humanity is to discover a way to reduce our reliance on unsustainable resources, like fossil fuels. Most, if not all, modern industrial societies rely far too greatly on fossil fuels and increasingly, this is becoming an undeniable reality. Wars of conquest are being waged to secure what is left of the world’s oil reserves. If only the resources of the powerful nations were channeled into developing sustainable energy alternatives, as opposed to driving a war machine bent on dominating the oil markets. Our modern way of life is going to undergo some difficult times in the very near future, if this reality continues to be ignored. Ask yourself what you can do to make a difference. You might be surprised at what you can accomplish.

The Homeowner’s Guide to Renewable Energy: Achieving Energy Independence through Solar, Wind, Biomass and Hydropower

To develop environmental friendly methods in generating power is a brilliant renewable energy innovation from a renewable energy company. Producing renewable energy powered generators for unfaltering energy supply and cut down the cost of energy utilization. Harnessing renewable energy resources for a clean energy supports the environment as well as the future. Here are five of the best renewable energy innovations.

First thing that come in mind when renewable energy is mentioned would be the solar panels. They come in all sizes to fit the needs of every household. When it first came out solar panels are so tiny it can only power a calculator. There are two types of solar panels, first is the solar thermal collector that heats waters for consumption or homes. A solar thermal collector is basically made of an insulator box and a black metal absorber. Natural convection takes place with solar thermal panels and is widely used in sunny European countries to cut down water heating costs. The other is the photovoltaic panel. These are solar panels that are made of wafer based crystalline silicone cells or a thin- film based on cadmium telluride or silicone. It converts light energy, thus the name photovoltaic, into energy by photovoltaic effect. Solar panel reduces carbon emission in the atmosphere promoting cleaner energy.

Second is the windmill. Water as a renewable energy resource has been known to man since the late 600 AD. Windmills are used to grind up produce and draw water up water. Modern wind mills or properly known as wind turbines makes use of the wind to produce electricity. Wind turbines convert kinetic wind energy into mechanical energy then into electricity. There are two types of wind turbines, namely the horizontal axis wind turbine and the vertical axis wind turbine. Between the two, the horizontal axis wind turbine is more common than the other. Everybody can recognize a tall tower with horizontal axis blades are called wind turbines.

Third is a biomass powered generator. Who knew that there’s a Do It Yourself version of this contraption. Now left over food and animal litter has more usage other than fertilizers. On a larger scale, Biomass, being the most abundant of all can generate powers providing large farmlands and forests. A renewable energy company that utilizes biomass normally makes use of the biomass steam cycle to generate electricity. Other ways of utilizing biomass is by extracting biomass fuel from decaying materials.

Fourth is making use of tidal power. Tidal steam generators produce incredible amounts of energy due to the high density of water flowing from the ocean. Geographically speaking, this type of renewable energy is only available to countries that have access to the sea or coastal areas.  It is considered as one of the best long term renewable energy resources in the world. Using tidal turbines rather than coals to run heavy machineries can reduce the output of greenhouse gases in the atmosphere.

Last would be nuclear powered generators. Although it is highly debatable, nuclear power is an abundant resource for us to utilize. It can generate power twice as much as fuel and other resources combined. The downside of this would be that there are much health risks involved in putting up a nuclear power plant.
