Solar Power – 3 Must Know Answers Every Homeowner Should Have

Have you been considering harnessing the power of the sun to reduce the impact on the environment and lower your home energy costs with solar power? This article will help you understand how solar energy can help you.

Using the sun as an alternative source of energy is becoming more and more widespread. Unlike fossil fuels such as oil, coal, petroleum and natural gas,which cannot be re-grown, produced, regenerated or reused, there is an endless supply of energy created by the sun.

The reasons for choosing this energy source range from the desire to live off the grid to the fact that this form of energy is more eco-friendly.

How is solar power created?

Solar power is created when the sun strikes a solar cell and a chemical reaction occurs generating electricity. This energy can be used to heat your water (solar thermal) and create electricity (photovoltaic) for your home.

There are several factors that can determine the extent of energy created by a solar panel or cell. If you have open areas with full sun to the south the likelihood of living off the grid or having a major reduction to your utility costs is greater.

How much can I save?

In an optimal area you can expect to see a 60% decrease in energy costs by using a solar energy source. Depending on the geographical area, it is possible for a home to create an excess amount of energy from solar power that the utility companies will purchase from the homeowner. This would allow a person to live off the grid.

What is the difference in solar energy sources?

Passive or active are the two classifications most often used for solar space heating systems.

Think about the inside of a car on a hot summer day. The inside of the car is heated up by the sun’s rays. This is similar to what happens in buildings with passive space heating. Air is circulated past the surface of solar heat and throughout the building.

A collector is used to absorb and collect solar radiation in an active heating system. The heated air or heat absorbing fluid is circulated by using fans or pumps. Flat-plate collectors are often used for heating buildings. These are known as non-concentrating collectors.

Does the south side of my home have to be clear and open to the sky?

It is widely thought that the south side of your dwelling should have a clear view of the southern sky. However, if you’re priority is to defer winter heating bills you will be pleasantly surprised to find out that if you have deciduous trees planted on the south side of your home they will provide relief for your winter and summer utility costs.

In the winter months when you want to get the most effect out of your solar energy source the limbs are bare allowing the sun to pass through to your solar panels.

In the summer months the full leafy limbs provide shade to cool your home.

Now that you have a better understanding of what solar energy can do for you go ahead and get started. Check out what works best in your geographical area and get ready to start saving money and the environment with your own solar energy system.

Renewable energy indeed is effective and has helped thousands of household nowadays in cutting their electricity bill. It is not necessary that we will be enslaved by electricity suppliers with their expensive electricity.

Discover How Much Solar Panels Cost – Are They Over Priced Or Can You Afford One

For many American households today, a lot of them are considering the idea of using solar or wind panels in order to generate electricity for their homes. This is very true to the extent to which our economy status is. The year is 2009 and things are not looking pretty where money is concerned. So in order to save the little money that millions of Americans have these days, they are considering the idea of solar panels to create their own electricity. “How much do solar panels cost?” is just one question that rolls of the tip of many peoples lips.

In answer to this common question, solar panels cost a lot of money if you go down the route of purchasing them as a brand new unit and having them installed. The materials of these devices are specialized materials which go into the manufacturing of each photovoltaic or PV cells. This results in high production costs which simply mean high prices. Its always been the case with these solar panels. In addition to that, as the trend for alternative energy continues to rise, the higher the demand for this type of technology, then the higher the price for these devices will follow.

Alternative energy is a growing trend that is rapidly catching on. There are two primary reasons for this growth. Number one is that it saves people a lot of money as it generates its own electricity. The other reason is because its kinder to the environment as it doesn’t submit CO2 emissions like traditional energy companies do. Apart from the materials that cost a lot of money when producing these professionally made solar energy devices, the other reason why I can see that these devices are expensive is because there is only a small amount of companies that are producing these for a market that is in high demand. This also drives prices high and I believe that if there were more companies developing these devices it would become more consumer friendly in terms of price!

Commercially produced solar panels cost a lot of money. They are anywhere from a few hundred dollars up to tens of thousand dollars. So they really have a price tag that out prices many people that are looking to use solar energy in order to power their homes. So what do you do if you are priced out of the market? Is their an alternative if solar panels cost to much money? Well… I am happy to report that there is an alternative to this. You’ll be even more excited to know that systems are not going to cost you an arm and a leg! Why is that?

Simple… the only way to avoid this type of expense is to go ahead and build one of these devices yourself. Now don’t get scared because its not as hard as you may think. In fact there are thousands of people that are doing this type of project and becoming very successful at it too! How did they do it? They bought a DIY guide to building their very own solar power energy system. There are a few of these guides that are very successful in teaching anybody how to generate their own electricity. If you get your hands on one of these you can generate your own power for your home which in turn can save you heaps on your power bills. Commercial solar panels cost a lot of money, but you need not worry if you get your hands on one of these guides!

Advantages And Disadvantages Of Renewable Energy Sources

What are the Advantages and Downsides of Using Green Energy Sources?

Now, we are right now conscious of the aftermath of worldwide warming. Luckily, it isn’t too late and we can still modify which is why many are pushing for inexperienced energy sources.

The advantage of using green power is that it’s clean so it is unpolluted so it doesn’t emit something harmful into the air which has an impact on the atmosphere. It’s also renewable which implies we will never run out of it unlike oil which is predicted to dry up in ten years or so.

While inexperienced energy services are costly to construct, it needs less repairs so you do not have to shell out a large sum of money to operate it.

It can also bring industrial advantages to chose areas even increase tourism.

Even as these sound good, there are some who say that there are advantages to using such technology.

While clean energy sources could make electricity, how much it may make just isn’t consistent. The reason we’ve got no management of the weather so if a sure area relies on solar electricity and there’s a weather distraction, it will be unable to convert sunlight into electricity.

Building these services also requires a lot of land so we may have to cut on farmland which is what many are nervous about if more air turbines are to be put up.

A totally different disadvantage is the fact that a number of the renewable energy sources can’t be installed in selected areas of the earth. For example, wave energy can only be employed if the waves coming from the ocean attain at least 16 feet. The use geothermal energy can only be executed in geologically unstable parts of the earth.

But if you have a look at such arguments, locations that can’t use one form of renewable energy source could be substituted for another. If turbines want more space, they are often installed near the coast relatively than putting these on land. A study shows which you can make more electricity whilst these are within the ocean.

Even as the weather is a thing we won’t control, it isn’t everyday that there’s a weather disturbance so this too shall pass. If solar electricity is being used and the sun is covered, the emergency generators might be turned on and burn up the energy that was stored.

The level is that there are tactics round the discussions put by certain folks which discourage the use of green energy sources. Actually, research is continuous to try and harness different means to make the facility we want.

A very good example of this is called ocean thermal energy. Power is generated by harnessing the altered temperatures in the water. It is currently being used on a tiny scale both in Japan and Hawaii.

In the US, solely 7% of inexperienced energy sources are used countrywide. This was approach higher eleven years ago and if we don’t have to worry about the cost of oil or possibly reduce our reliance on it, we need to invest more in this clean energy.

We can get it from inexperienced energy sources reminiscent of biomass, biodiesel, geothermal, solar, water and the wind. These are things we’ve all around us and all it takes is for someone to harness it as an alternative of relying on normal non-renewable means to produce energy.

Renewable energy indeed is effective and has helped thousands of household nowadays in cutting their electricity bill. It is not necessary that we will be enslaved by electricity suppliers with their expensive electricity. We can always study basic solar energy facts and renewable energy information on http://www.freealternativeenergyresources.com/ and learn how to save and use electricity wisely.

Alternative Energy – Renewable Energy And Clean Energy Definitions

To most people, the differences between “alternative energy,” “renewable energy,” and “clean energy,” might not be obvious. But every term is exclusive and has its own individual meaning.

Alternative Energy

When we converse of alternative energy, we consult with sources of usable energy that can replace conventional energy sources (usually, without undesirable facet effects). The time period “alternative energy” is typically used to confer with sources of energy aside from nuclear energy or fossil fuels.

Throughout the course of history, “alternative energy” has referred to different things. There was a time when nuclear energy was thought of an alternative to standard energy, and was therefore called “alternative energy.” But occasions have changed.

These days, a form of “alternative energy” may also be renewable energy, or clear energy, or both. The terms are sometimes interchangeable, but positively not the same.

Renewable Energy

Renewable energy is any type of energy which comes from renewable natural resources, such as wind, rain, sunlight, geothermal heat, and tides. It is referred to as “renewable” as a result of it doesn’t run out. You can always get more of it.

People have begun to turn to the sort of energy because of the rising oil prices, and the prospect that we might sooner or later deplete available sources of fossil fuels, as well as due to concerns in regards to the adverse results that our standard energy sources have on the environment.

Of all the various kinds of renewable energy, wind power is one which is growing in its use. The number of users who’ve some form of wind power put in has increased, with the present worldwide capability being about one hundred GW.

Clean Energy

“Clean energy” is simply any type of energy which is created with clean, harmless, and non-polluting methods.

Most renewable energy sources are additionally clean energy sources. But not all.

One such example is geothermal power. It could also be a renewable energy source, but some geothermal energy processes may be harmful to the environment. Therefore, that is not at all times a clean energy. However there are additionally other types of geothermal energy that are harmless and clean.

Clean energy makes the less impression on the environment than our current typical energy sources do. It creates an insignificant quantity of carbon dioxide, and its use can cut back the speed of worldwide warming – or global pollution.

As you’ll be able to see, these three terms: alternative energy, renewable energy, and clear energy, are very similar. But you will need to know that there are differences.

There are many steps which may be taken to assist reduce greenhouse gases in our atmosphere. Some of those steps will be taken in your personal home. Many clear energy solutions can may be easily installed, and a few kits are quite affordable.

Carbon emissions and other forms of pollution aren’t only created by heavy industrial factories. They are created within the common household as well. Energy efficiency has grow to be an important aspect of our lives.

It’s vital to start making adjustments now; if we need to save our planet for our children, for the wildlife of the Earth, and for the way forward for mankind. Clean energy, to be exact, can make an enormous difference.

Renewable energy indeed is effective and has helped thousands of household nowadays in cutting their electricity bill. It is not necessary that we will be enslaved by electricity suppliers with their expensive electricity. We can always study basic solar energy facts and renewable energy information on http://www.freealternativeenergyresources.com/ and learn how to save and use electricity wisely.

The Most Profitable Advantages Of Renewable Energy

Undoubtedly, as you will have read or heard before, exploiting renewable energy presents varied advantages, starting from environmental to economical aspects, from moral to merely technical aspects, together with its challenges of course. Among all the advantages I will consider those which may have a large-scaled influence in our lives throughout the planet. Extraction, effectivity and echo-friendliness are the facets which I want to focus on, and we will compare renewable vitality and non renewable vitality in all three aspects.

Extraction

Or better said no extraction needs at all.

In fact, renewable sources such as wind, solar, tidal power don’t need any extraction course of and they are the most typical resources on the planet Earth. It means no danger for people, no hazard for the surroundings and no high energy input with a view to have them available.

Geothermal and hydro power want special plants and will have environmental impact, however far lower than the beneath mentioned abnormal resources and normally the process is far easier.

Instead, to have our strange (or what we call ordinary) energy resources such as oil, coal, uranium, etc., we have to make huge efforts to find, extract and transfer them. Then using particular plants they are transformed into helpful electric energy. As you possibly can see there are a minimum of three stages before having what we need. In each of the phases a high power input is required to reach our outcome. The extraction of those “ordinary” vitality resources, together with a high power input, can also be a big danger for the individuals involved within the process, and often brings devastating penalties for the environment.

Needless to say, at first sight, comparing the extraction side of renewable versus “ordinary” power resources, the advantages are clear, but let’s take into account more.

Efficiency

When it comes to considering efficiency the benefits brought from the implementation of programs that use renewable power resources are amazing. A wind generator, a pretty easy machine, to rework wind into electricity might convert as much as 50% of the overall wind energy, a photo voltaic panel converts up to 60% (in new era cells) of the general solar power that it collects. Even with a decrease efficiency, corresponding to that we now have for tidal power plants (up to 30%) it’s not bad, if you happen to consider the overall absence of threat for human and environment. Exploiting much less then 0.02% of the general amount of solar energy that each day reaches our planet can be enough to satisfy our (world’s) vitality demand instead of extraordinary power plants that use coal or oil as a flamable and have the effectivity that doesn’t go over 25%. Not performance indeed!

Let’s go further and analyze a bit what happens regarding environment.

Echo-friendliness

When utilizing renewable resources, we don’t need to search for, we don’t have to extract, we don’t even need to move any flamable across the globe, neither we want any special, polluting and complicated power plant to take advantage of them.

Tidal, hydro, wind and photo voltaic power might be easily discovered and transformed into electricity directly from those fundamental machines. When no mining or extracting is needed, two things occur: some huge cash is saved and quite a lot of destruction is avoided. Using simplest power plants, such as these used for tidal, hydro, wind and solar vitality one stage is omitted within the energy transformation process (combustion), hence higher energy efficiency is reached and no pollutants in any respect are emitted, not even 1 gram of CO2.

Not the identical for ordinary resources, the crops for mining or extraction entail pollution and waste of energy, in addition to transportation does. The power plants wanted to burn the flamable are more complicated and horribly expensive. In the transformation course of 75% of the energy is consistently wasted and as if it wasn’t enough, thousands of tons of CO2 together with a dozen of other poisons are emitted yearly from a single power plant.

Extraction needs versus no-extraction needs, with all the consequences, low efficiency versus larger efficiency, air pollution versus echo-friendliness are mainly our terms of comparability between non-renewable and renewable sources but, beside those, there are a number of others.

Yes, things may look a bit shocking, but that’s the truth, this is exactly an summary of how issues are going, right now, in our world. Many are the reasons for this situation, however mainly, a widely diffused misinformation as a lot as a couldn’t-care-less perspective plays a significant role in this game.

Those are the enemies we must always fight immediately.

Renewable – Sustainable Energy Solutions For Our Future

With the increase in concern over the release of carbon dioxide into the atmosphere and the decrease in the supply of fossil fuels for energy, researchers are constantly looking for renewable, sustainable energy solutions. This means that a lot of time and energy is being put into the successful application of energy sources such as solar energy.

Solar energy is at the top of the list of these future energy sources because the sun is one thing that is not likely to go away any time soon or at least within our immediate lifetimes. Also, the sun releases one thousand watts of energy per square meter. This energy is the same all over the globe which is available to anyone and is a renewable supply on a daily basis.

Right now the problem with using solar energy on a high yield level needed to supply large areas is that at this point in time, the technology simply does not exist to adequately capture all of the solar energy and process it successfully. Technology is evolving to make solar panels capable of processing more of the energy that is passed through them. Hopefully in the near future we will be able to rely more and more on sunlight as a sustainable form of energy that will help cut back (or possibly eliminate) the need for burning fossil fuels.

There is however an increasing number of people that are converting their individual homes to utilize solar energy. Infrastructure on a mass scale may not exist to power entire communities and cities but at the individual level people are able to capture and successfully use this energy for their own needs. This is the direction the world is moving toward, clean, renewable and sustainable energy.

So effective is this method of energy production that the herdsmen of Mongolia, who because of the far reaching expanse of its steppes are isolated by vast distances from the power grid and therefore rely upon solar energy to supply their electrical needs. They are now able to bridge the great divide in technology that physical distance has kept them from in the past and now use cell phones while riding their horses.

Another form of energy that is capable of being renewable and sustainable is nuclear power. However, there are many concerns over this type of power source and the dangers that can arise if not handled properly. Apart from the fact that contamination and melt downs are an ever present reality, nuclear power is dangerous because of its byproducts which cannot be reabsorbed or destroyed.

In fact the byproducts from nuclear waste take millions of years to break down which means that they can never be dispersed freely into the ecosystem making storage a nightmare.

There is only a finite amount of space and the nuclear waste is fast filling up. While nuclear power fulfills an immediate need for us, we never know the aftermath or the far reaching consequences our future generations will inherit. So, while this energy source is one that will be capable of running large amounts of energy for many years to come, it has some serious drawbacks that must be taken into consideration if it is going to be used on a larger scale in the future.

For the time being, researchers continue to look for ways to implement renewable, sustainable forms of energy that can be used well into the future without harming the environment. The sense of urgency has increased as the concern over the environment has been addressed on the national stage where energy companies are exploring the use of solar, wind, and hydro power where they can.

Unfortunately for the time being, we have to continue to rely on fossil fuel energy until a realistic solution presents itself. What we can do right now is reduce our demand on these natural resources in order to preserve them for longer.

Renewable energy indeed is effective and has helped thousands of household nowadays in cutting their electricity bill. It is not necessary that we will be enslaved by electricity suppliers with their expensive electricity. We can always study basic solar energy facts and renewable energy information on http://www.freealternativeenergyresources.com/ and learn how to save and use electricity wisely.

The Popular Types Of Renewable Energy

One can’t go far these days without discussions of energy issues arising. Renewable energy sources are part of that discussion, but what exactly are the types available?

Renewable energy is somewhat of a catch all phrase. It refers not to one energy production method, but to many types that have one thing in common. They all use an energy resource that is freely available and does not run out per se. Let�s take a look.

Solar Energy Solar energy is considered a renewable energy source because it uses the power of the sun to produce electricity and heat. Since the sun isn’t going to burn out any time soon, it is a free power resource for the next four or five billion years.

Wind Power – Wind power is actually a type of solar power. Wind is produced when the sun heats of different surface areas at different rates. The air over hotter surfaces rises and cooler air rushes in to fill the gap. This is wind. As long as the sun is shining, we will have wind. We can harness wind for electrical production through turbines. The wind turns the blades of the turbines, which crank a generator that puts out electricity. Wind power is currently the fastest growing renewable energy platform in the United States.

Hydropower – Hydropower is electricity generated by damming a river. Turbines are built into the dam. Much like wind power, water flows down through the dam because of gravity and spins the turbine fans as it passes. This cranks a generator, which produces electricity. Hydropower currently accounts for 10 percent of the electricity production in the US, but is losing popularity as building dams is very expensive.

Biopower – The great hope of President Bush, biopower is based on the idea of using organic material to produce fuel for cars, heating and so on. It is better than using fossil fuels, but has some serious disadvantages. Ethanol, for instance, can help replace gasoline, but it produces a ton of smog. Processing organic materials also takes nearly as much energy as it produces in the form of fuel and such. All and all, this is one of the weaker renewable energy resources.

Geothermal – This renewable resource works by capturing the steaming water temperatures in the earth’s crust. If temperatures reach 240 degrees, the inherent energy can be converted to electricity. Geothermal is a great idea with limited application. The problem? It is not readily available. In the United States, only California, Hawaii, Nevada and Utah can support geothermal plants.

Renewable energy is definitely the wave of the future. Sooner or later, we are going to have to convert to these energy platforms. With huge oil companies buying up solar and wind power companies, it looks like the future may be sooner than we think.

Renewable energy indeed is effective and has helped thousands of household nowadays in cutting their electricity bill. It is not necessary that we will be enslaved by electricity suppliers with their expensive electricity. We can always study basic solar energy facts and renewable energy information on http://www.freealternativeenergyresources.com/ and learn how to save and use electricity wisely.
