There’s a lot of talk going around regarding the most energy efficient sustainable home known as passive houses. These houses are extremely environmental friendly which will supply a quite comfy environment on the inside by way of the balance of fresh air supplies without too a lot help from heating and cooling processes in the course of colder and warmer days respectively. They’re known as passive houses since the developing can heat and cools down in itself without having any 3rd party involvement.

Once you take a look at the equation of energy consumption, it is normally much less than the standard houses taking into consideration the truth that you are able to save up to 90% of energy. In case you combine electricity and heating program expenses, the energy consumption cost of passive houses is much less than a quarter of it. Therefore, the application of these energy efficient houses will absolutely assist you to save much more on cash spending also as protect the environment at the exact same time.

These passivhauser function on four key areas including insulation, solar and internal gains, air-tight seals and indoor air high quality. The home built with this energy effective system has incredibly high level of insulation. Additionally, the use of solar and internal gains sees to it that you are able to get balance of heat inside the residence. The air-tight seals make certain that you reduce your energy losses.

Furthermore, the high quality of the air inside the house is maintained and balanced due to the mechanical ventilation system incorporated in its design. With all these parameters in check, you’re guaranteed that your residence can sustain through time with out putting so significantly dent within your finances. You do not need any standard heating systems with these passive houses or any active cooling system for that matter.

You are able to guarantee that you can be comfy living inside such property. There’s little demand in heating and you can meet this via a little electric heating device within the ventilation system but there are also several other solutions. As a result, they’re incredibly eco friendly and budget friendly at the identical time. This means to say that you won’t have any more issues along with your monthly bills.

In case you figure out how critical all these choices in energy efficiency is right now, you’d know that passivhaus are great in making comfortable living. You’ll be able to learn a lot more about this via sites that include data about this innovation.

Solar PV Panels A Vital Element Of An Overall Photovoltaic System

Posted on 23rd May 2011 in environment

Solar electrical systems are increasingly being installed all around the world by private households to decrease their electricity costs. This process also reduces their carbon emissions and contributes toward a greener environment. Solar PV panels are a critical part of these photovoltaic or PV systems.

Solar Panels

Solar Panels

Radiant energy from the sun is free and in limitless supply. As fossil fuel prices (for coal, oil, gas, and so on) have increased through time, the financial rationale justifying a switch to cheaper energy alternatives like solar power have become increasingly compelling. Some governments around the globe, particularly in Europe, have already introduced tax rebates, subsidies and other incentives to encourage customers to install photovoltaic or solar power systems.

A solar panel acts as a collection surface to harness the energy carried by ultraviolet sunlight. The panel is comprised of many solar cells interconnected or wired together. The cells are the central core of the panel, its heart. In addition to capturing the radiant energy, each cell also serves as a diode, permitting electric current to pass in one direction only, blocking current from flowing in the opposite direction.

A cell is the critical piece of equipment that transforms ultraviolet radiation (sunlight) into electricity. By comparison, the panel is simply a base onto which the cells are fixed and wired together into one interconnected system.

A domestic PV system usually has a generation capacity of up to about 10.0 kw of electricity. An average, four-person modern house needs about 7.0 kw of electricity. To be clear, a 7.0 kw system flows 7,000 watts of electricity, sufficient to power 70×100 watt light globes. These domestic PV systems are not cheap; they cost many thousands of dollars.

A 7,000 watts PV system is a large configuration, likely requiring over 40 big solar panels. Most domestic systems would probably be smaller installations with smaller capacity. A 7,000 watts solar power system would allow a household to achieve significant power savings (perhaps upwards of 30 percent). The system would also lower carbon emissions by at least 10,000 tonnes per annum.

Panels vary in size largely based on the size of the cells which are mounted in them. Panel size is also limited mainly by practical logistical requirements related to handling and installation. Panels are normally fixed onto ground-based racks or building roofs. To maximize exposure to sunlight, they point south when north of the equator and vice versa. To maximize the conversion efficiency of cells, panels are inclined to the sun (usually at about 30 degrees). Scientists have confirmed that to optimize conversion efficiency the inclination angle should vary through the day, as well as day-by-day through the year, as the position of the earth relative to the sun changes.

Professional installers are available to install solar PV panels. These highly trained tradesmen are usually registered or certified by a central industry association or body. Installers can assist customers configure the entire PV system that will best meet their needs.

Installing a solar pv on your home or business to lower the cost of electricity remitted to the utility company is fast and easy. You can take advantage of the free and clean energy provided by photovoltaics in an array panel.

Solar Energy – The Main Advantages

Posted on 1st May 2011 in solar power

Renewable energy sources like solar energy and wind energy offer people many advantages. Solar energy, for example, is the best source of energy humans can utilize to its fullest potential. Solar energy is the energy coming from the sun and is virtually limitless and offers many solar energy advantages. This means that humankind can use this energy for whatever they intend to and for how long they wanted to.

There are many solar energy advantages. First on the list of solar energy advantages is that it helps in saving Mother Earth. The next advantage is what really lures people into using it – cost cutting. And of course, one of the solar energy advantages is the government incentive programs for people who are going green.solar panels

The price of today’s electricity from commercial power companies is steadily rising and that is why using solar energy is such a tempting option. There will be no recurring monthly expenses when you use solar energy. What you would pay is for an up-front payment for installing a solar system that will provide you electricity from solar energy. Once done, there will be no need to worry about additional expenses since the solar panels that will be installed are long-lasting and only requires little maintenance. Moreover, there are no longer power interruptions since solar energy can provide continuous electricity.

One major solar energy advantage is its cost cutting benefit. You see, the only time that you are going to spend a considerable amount of money when using solar energy is during the installation of a solar power system. After that, there will be no more additional costs. The maintenance for the system is not that much of a burden. Solar power systems are long-lasting and stay very efficient. Moreover, solar energy makes sure that there would be no power interruption since the energy captured can be stored in a battery for later use.

Government incentive programs are also there to aid future green individuals. These programs include tax exemptions or reductions, financial aid, rebates, and additional renewable energy source laws. All of which are aimed to help those individuals in switching to a greener electricity source. If you wanted to earn money while saving Mother Earth, you can also do that. Simply sell back the excess electricity produced by your solar power system to the national grid and you can earn some money at the end of every year or a certain time period. This is made possible because the government allows it.

There are many advantages that solar energy offers to people. All of them can be beneficial not only for the person using solar energy but to all of humanity. When using solar energy, you can save money while saving the Earth.

Understand What Free Energy Research Is

Posted on 11th April 2011 in energy

You could define free energy research in a number of ways but we will focus on just three. One meaning is that it is a device that can generate electricity with the help of some kind of source that has not been recognized scientifically. Next, free energy is referred to as a kind of perpetual motion machine. Last, it most commonly referred to as a device with the ability to collect and distribute energy for free.

The one scientific definition that seems to be the most agreeable would be the first one. If a device can generate free energy with the help of say a nuclear reactor, then it would be considered as a free energy device but only if it were being used in the 1890′s unfortunately.

In the present context, if a scientist found out some way to generate electricity out of neutrino flux or harness gravity, then that would be free energy as well. But there is a catch here.

Out of all these definitions it is the first scientific definition that is the most feasible. By going with this definition, in theory, nuclear reactors could be considered as a free energy device (in the 1890′s).

For example, Becquerel discovered that fog plates could effectively filter uranium ore and he invented a device based on this discovery. Uranium ore was considered as free energy up until scientists summed this unusual phenomenon up as radioactivity of unstable elements.

As an example we will use Becquerel who discovered that fog plates can filter uranium ore. Based on this discovery, he invented a workable device that could do just that. But, scientists could not explain the strange phenomenon by way of radioactivity of unstable elements and because of that uranium ore ceased to be classified as free energy.

But the problem with free energy is that a lot of people do not believe in it. So though there are a lot of enthusiasts among this group, it usually has to face criticism in the hands of self acclaimed specialists.

This has made research in this field difficult. But the research continues to take place and scientists continue to make successful the devices in the midst of all odds.

What Is Solar Energy?

Posted on 5th April 2011 in environment

Solar power is all around us, and is energy that comes directly from the sun. It’s everywhere and everything. We depend on the sun for many things. This kind of energy is the best kind of energy that there is! It is also safer and better for the environment.

Today in society, we use this form of energy for many things. Some of these things include drying clothes, the production of electricity, and the heating of water. That’s still not all of the uses for this specific type of energy. Solar powered calculators have been popular for years. Fans can run on solar power, and pools are heated with simple covers that collect the sun’s heat. Did you know that you can also cook with it! As electricity costs rise and the focus on protecting the environment increases, more and more people are taking notice of solar energy. They’re seeing how it can be put to use to save electricity. Because of this, this type of energy is becoming more and more popular.

This form of energy is really interesting and has many interesting facts. Like electricity produced using other means, solar power is measured in kilowatts. About thirty percent of the energy we use to heat our water comes from the sun. The technology used to collect and store solar energy has been around for years. Did you know that Da Vinci predicted most of this solar stuff that we have going on today? He predicted most of this way back in 1447!

Some people are “going green” and eliminating a lot of things from their home. Electricity is one of them. They do have electricity, but they will not have a bill to pay because they made their home into a solar home system. Many people make the switch because it saves them money and also helps the environment. You can buy a solar energy system for your home, or put one together yourself. You’ll need solar panels, a battery, an inverter, wiring and structure support.

Solar power is awesome. Did you know that more sunlight reaches the earth in one hour than the whole population of the world is capable of using in an entire year! Solar energy is more powerful than we realize. It’s strong enough to impact weather patterns and ocean currents.

If the sun is blocked, its rays will not be able to reach the earth. Clouds can reduce the amount of sunlight that gets through. Wind and pollution have an effect too. If we can reach this unlimited source of energy, we could do so much with it. We could greatly reduce our use of coal powered electricity, natural gas and gasoline, using solar energy instead.

Americans account for only five percent of the world’s population, but we use about twenty six percent of its energy. Taking care of the environment is not hard to do at all. We need to save resources by using what we have instead of creating something new. Solar energy is an ideal way to do that.

Our society today uses this all natural energy from the sun to power a huge array of things. The environment has taken care of people for many years and will continue to take care of them for many more to come. You can start making the world a better place to be by using the energy that is already supplied instead of cutting down trees and decreasing oxygen levels for animals as well as humans.
