Alternative Energy Sources

Article by je Dunn

We are surrounded by Alternative Energy sources if we just care to utilise them.

Most people immediately think of solar energy which utilises photovoltaic cells to capture energy from the sun and fortunately these cells are becoming more affordable.

The Solar energy power provides a lot of helpful uses such as for generating electricity, heating and making hot water with the fact that it can cause no pollution since it is entirely dependable on the rays of the sun.

Even so, we are still in the early days of using this ‘free’ source of unlimited energy and a good deal more research and development is still required. Since solar energy cannot be used during the evening and on gloomy days, provisions on the resource is unavoidable that is why backups in the form of storage batteries are utilized.

Usually for now, a large number of private investors as well as the government take pride and support in investing for the utilization of wind energy as an alternative energy source.

Using the wind’s kinetic energy once its motion have been captured can greatly contribute to conversion of mechanical or electrical energy and this can be done through the development of “wind farms” which is the placement of great arrays of triple-bladed windmills all over the place. The idea of using a windmill to exploit energy is something that we all are already aware about.

Replacing the classic method is the more advanced variation in the form of modern wind turbines. The only downside to this form of power is when the wind isn’t blowing, you cannot produce power. When the wind doesn’t blow we have other power stations that can make up the energy deficit so we cannot, at present use wind farms as a primary source of power.

Another source of alternative energy that can generate an extensive amount of power is accessible in the form of hydroelectric energy. The downhill motion of water implying its flow in response to gravity is used to turn turbines and as a result, generate electrical energy and this is the process in which hydroelectric energy works.

As water is everywhere it has not generally been a problem finding locations where it can be employed. However, hydroelectricity as a source of alternative energy can be complicated and expensive to produce. Each dam is built from scratch and must be strong enough to hold back the huge amount of water that will be neede to make the dam a viable proposition.

There’s always a risk and hard work involved in building a dam to store and control water’s potential and kinetic energy and the complication of its operation is another factor that contributes to the growing concerns of the conservationists.

If you are not trying to look after a large town or city, it probably won’t be necessary to employ a large dam as other sources are available. There are a number of run-of-river, hydroelectric converters available which can easily service smaller communities without much environmental impact.

When artesian waters just below the earth’s crust are heated, a naturally-occurring energy in the structure of geothermal energy can be produced which is more often than not the most underrated form of alternative energy that gains less of the gratitude and pride.

This heat is transferred into the water from the earth’s inner molten core. The water is drawn up by various different methods-there are “dry steam” power plants, “flash” power plants, and “binary” power plants for harnessing geothermal energy. When hot water is drawn up, it simply means that there is the need to gather steam.

It is in the USA where this technology has become world famous with ‘the Geysers’ dry steam power plant not that far from San Francisco.

As the price of oil grows and the economy continues to stumble, the people realize that something must be done. What is that something? Well that something is turning our attention away from fossil fuels that are expensive and ruin the environment, towards some form of Alternative Energy that can, in the long run save the people money and help prevent mass pollution.To date, the United States is one of the largest users of fossil fuels in the world which has devastating effects of the environment. So of course a better form of energy must be found. Fortunately we don’t even need to look because Alternative Energy has been around for years. These different forms of Alternative Energy include wind, water, and sun. We could easily harvest the different forms of Alternative Energy that are seemingly endless in supply and help the fix the energy crisis as well as many of the world’s problems with pollution. Transitions to accommodate the harvest of this Alternative Energy may be expensive but the Wind Mills that would harvest wind power would pay for themselves in a matter of years, the Solar panels that would gather the sun’s rays would do the same and the hydro generators that are powered with water are in the same boat. These Alternative Energy sources are safe, healthy and after a few years they even become much cheaper than conventional fossil fuels since the supply would be constant and not depends on the demand of the populace. These forms of Alternative Energy help the world become a cleaner place for ourselves and brighten the future for generations to come.Contributing to the fight for Alternative Energy is simple. You can have solar panels installed, which although expensive can actually turn a profit in the long run, or if you cannot do that then write to your local senator or congressman demanding that legislation supporting the creation of Alternative Energy and significantly decreasing the dependence on fossil fuels be passed. They were elected by us, so they work for us. Make your voices heard!

Sources for Alternative Energy

At this time there are a lot of assorted forms in which alternative energy is obtainable.

Among these is solar energy. Solar energy is forced by solar cells, and these are increasingly becoming less costly and more innovative. Solar power could be utilized for electrical energy, heating, and attaining warm water. Solar power brings forth zero pollution, because its stimulus hails totally from the sunlight rays. Nonetheless, a great deal more work still demands to be done in order for America to economically tackle the sunshine’s energy. For the moment, the resource is a bit too tentative-accumulator batteries are required to be applied as supports in the evenings and on cloudy daytimes.

Wind energy has become the most-invested-in (by individual investors and governing collectively) alternative energy resource for the moment. The big ranges of triple-bladed wind generators are being based everywhere as “wind farms”, to seize the movement of the air current and apply its kinetic energy for transition to mechanized or electricity. Naturally, there’s zero Modern about the conception of a wind generator for harnessing energy. New wind turbines are merely more innovative versions on the older base. Naturally, the withdraw to wind energy is…what do you do when there’s a still, calm day? Needless to state, during these times the power company chips in for powering your house or business office. Wind energy isn’t completely independent.

Hydroelectric energy is visible as a resource of alternative energy, and it can yield a considerable sum of energy. Merely put, hydroelectric energy applies the movement of water-its current in reaction to gravity, which means downward-sloping-to convert turbines which then yield electricity. Unnecessary to state, water is ubiquitous; discovering resources for motoring hydroelectric turbines is, consequently, not a good deal of a trouble. Nevertheless, hydroelectricity as a resource of alternative energy could be complex and costly to develop. Dams are often assembled in order to be capable to contain the rate of flow of the water supply sufficiently to yield the required power. Constructing a dam to store and restraint water’s potential and kinetic energy requires quite a lot of work, and functioning one is complicated also, and environmentalists grow worried that it. Naturally, a dam isn’t ever required if one isn’t straining to render the electric demands of a metropolis or additional very densely lived urban area. There are little run-of-river hydroelectric converters which are effective for catering neighborhoods or an case-by-case business offices or homes.

Likely the most underestimated and under-appreciated type of alternative energy is geothermal energy, which is merely the naturally-occurring energy developed by the warming of artesian waters that are hardly beneath the earth’s crust. This warmth is channeled into the water supply from the globes interior molten core. The water supply is pulled up by assorted diverse techniques-there are “dry steam” power stations, “flash” power stations, and “binary” power stations for tackling geothermic energy. The intent of pulling up the warm water is for the accumulating of the steam. The Geysers, around a hundred miles magnetic north of San Francisco, is likely the best-known of every last geothermal power fields; it is an good example of a dry stream plant.

Wind Energy – Using Affordable Alternative Energy Resources

Wind energy has been in use since ancient times, propelling boats and warships, pumping water to thirsty farmlands and grinding grains. But this energy has never been fully harnessed, due to the convenience of other energy sources like coal and petroleum.

There’s a renewed interest in this free alternative source of energy, thanks to the realization that the world’s reliance on fossil fuels are causing major complications, including higher costs and environmental abuse.

What’s so great about wind energy? There are many benefits to choosing this alternative energy source:

Wind towers can be built on land or water, making them compatible with most locations
Wind power doesn’t pollute the environment
Wind is a renewable energy source
No harmful by-products are produced by wind turbines and wind power
Inexpensive operation means reduced energy costs

To generate electricity, a wind turbine is set on a tall tower to collect kinetic or motion energy created by the wind.

This energy is then converted by the turbines into the kind of electricity any regular household can use.

For personal residential use, electricity generated by a wind turbine on your roof and the power supplied by a local utility are combined. Why the need for local power supply when you already have wind energy? Wind speed varies, while smaller wind turbines are now efficient at wind speeds of 7-10 miles per hour, below that, little if any electricity is produced. As a result, local power supplies pick up the slack when the wind power generated is insufficient.

In some cases, you may find that your system generates more energy than you can use.

If your area is eligible for “net metering,” any excess electricity you generate is automatically sold back to the local energy utility, where you may receive payment or a credit. Once you are set-up to net meter, the process is automatic.

There are some considerations to take into account before installing wind turbines: location, general weather condition, zoning ordinances, size of home, and amount of investment. The wind option works best in high locations and in generally windy places. Your house should not be blocked by taller buildings or trees, allowing more wind action to propel the turbine blades to generate electricity.

There are two wind turbine types – horizontal axis wind and vertical axis wind turbines. The horizontal axis wind turbine produces more electricity but it has to be positioned to face the wind. The vertical turbine can catch wind coming from different directions, which makes this turbine a popular option.

For the home, wind turbines rated five up to 15 kilowatts can provide significant amounts of electricity. A turbine can be very large or, for home use, small turbines with a diameter measuring one meter or less will be appropriate. Unless you are a serious do-it-yourselfer, consider hiring a consultant to help you find the best solution for your particular needs. An expert can help with wind speed calculations, the best manufacturers, and provide installation and maintenance.

With all that wind blowing so freely, consider harnessing the power for your benefit. By converting wind to electricity, you can significantly reduce your residential consumption by 50 to 90 percent.

Alternative Evaluations

Free lunch? There’s no such thing.There are pros and cons to every energy source. Making the decision on how to best provide the energy society needs is a difficult problem.Many people think that weaning society off from petroleum consumption will make the current energy crisis go away. Even though alternative energy sources are being developed, the problems don’t go away, they simply change.

When alternative energy sources are evaluated, the following are important factors to consider.

Non-Combustion vs. Combustion

The majority of the current energy sources produce energy through different combustion processes (in other words burning) that requires oxygen, a burn chamber, and an exhaust system.From the beginning, man has burned wood for warmth. The process was very simple; Make a pile of wood, light it on fire, hang out nearby.Modern processes of cumbustion are designed to be much more efficient (today’s wood-burning stoves are about one hundred times more efficient than open fires, for example). But no matter how efficient the processes are, they are notorious to cause pollution.

Non-combustion processes, like nuclear and solar power, don’t give off the same pollutants, but they do have their own types of problems.Photovoltaic (PV) panels, for example, need a lot of energy for production, and most of this power comes from electrical energy produced from mainly coal combustion.The on-site implementation of solar is pollution free, but the production process requires a lot of pollution.Wind and hydo-power are examples of other non-combustion sources that require a large amount of energy to manufacture the equipment needed to make the system work.

Issues with raw materials

Whether it’s solar or a wood stove, every energy production plant requires raw materials.Raw materials are free in the case of solar.Uranium rods are the raw materials needed by nuclear power plants. These rods need to be meticulously refined and manufactured.The total cost of an energy process has increasingly less to do with the raw fuels.The most influential piece to the a cost/analysis equation is usually the expensive capital equipment needed.

The degree of energy refinement

In a rather crude method, wood stoves provide heat.Photovoltaic solar panels produce high-grade electricity.Another high-grade electricity provider is wind power.With the example of the wood stove, heat is the desired end product, and heat is very crude yet very effective.Electricity is very refined and convenient.The refinement of energy takes energy, and every energy-consuming process needs a certain level of energy refinement.Everyone would be best off if it were possible to adopt policies that promote less refined energy.

The amount of current technology

It takes quite a bit of time for new technologies to make it to the market. It takes even more time for those same technologies to become accepted and used.People tend not to completely discard whatever current system they have due to a radical new technology is developed.They will wait for their current system to fail or is no longer economical to use before they will purchase a new system.

Environmental and pollution impacts

A residue of some kind is left on our planet by every energy producing or consuming process.Alternative energy schemes are not all pollution reducing wonders.For instance, wood stove that burn wood inefficiently can be one of the most polluting energy sources.Different types of problems are caused by different types of pollution.

Financial aspects

The fact is that most people are concerned with cost exclusively and are only interested in decreasing their net costs for energy consumption.It is because of this that the government steps in with rebates, taxes, and other forms of subsidies to make these options seem more desirable.If the government didn’t mandate these economic changes, fossil fuels would never yield to alternatives.

Politics

Politics plays a huge role in the which alternatives get the most play because the government is going to lead the way into the alternative energy future.Green politics is becoming an influential and increasingly powerful part of government operations.

A Look At Alternative Energy For Your Home

 

 

You hear about alternative energy all the time on TV or on the radio, maybe even read about it on the internet. But just what is it?  Simply, alternative energy is just replacing one form of energy for another. Wind power instead of coal would be just one example among many. New forms of alternative energies are being discovered from research frequently. In the very near future, all of us will be using some form of alternative energy, if we are not already.

There are many benefits of using alternative energy in one form or another. Take for example less pollution. This isn’t a sermon on global warming or climate change, just a desire to live in a cleaner world. Research is continuing to make these new technologies more affordable to the public as expense is still a big issue. Some of the sources of alternative energies are still too expensive for many.

So, what kinds of alternative energy are there for the average person to take advantage of?  If you are a homeowner, you are in luck, as there are a few worth considering. To be sure, you have heard of solar panels. They have been around for quite a while and are increasing in popularity. The costs are coming down and their efficiency is increasing. There are many companies that will consult you on them and install them.

Another one you have heard of is wind power. For many of us, this is not directly feasible. Most of us live in urban areas or subdivisions that do not make it practical. Yet, for some, it is most definitely a viable alternative. If you own land and have the resources to have them put in, your energy costs could be reduced to zero. There are other alternative energy sources that can be employed in your home as well.

In order to drastically reduce energy costs, some people have used multiple forms of alternative energy. This is a viable goal for many of us to achieve. Indeed, there are yet other ways to use alternative energy to reduce energy bills over the long term. Hybrid  and fully electric cars are really making headway. This may not be practical for everyone, but the prices on many of them are reasonable. These are just a few things to think about on how you can use alternative forms of energy in our life.
