Using an alternative energy as a source of electricity is one of the hottest topics in this day and age. This is due to the fact that the supply of the fossil fuels cannot anymore accommodate the everyday energy or electrical consumption being made by all the people worldwide. Thus, the very best way, which you can do is to look for an alternative type of energy such as the solar and wind energy that can generate electricity. These two types of energy are clean, eco-friendly, free, and renewable. As a matter of fact, these characteristics are the reasons why most energy and environmental experts advise the use of a residential wind and solar power system.

There are actually a lot of benefits which you can gain once you utilize a residential wind and solar power system. Some of these benefits are as follows:

? The supply of wind and solar energies are infinite. This only means that there will be no such thing as a shortage in the supply of neither wind nor solar energy. This is due to the fact that as long as the sun is up there in the sky and just as long as you can feel the wind then, there is an adequate supply of both wind and solar energy. So, there is nothing to worry about the supply of wind energy as well as solar energy.

? You can save a huge sum of money annually with the residential wind and solar power system. This is actually the major benefit that you can get from a residential power system. This only implies that with the help of a homemade power system, you can now get rid of the high costs of your monthly electric bill, giving you the chance to earn a huge sum of money every month within a year.

? A residential power system, which uses renewable sources of energy like the sun and the wind, is irrefutably nature-friendly. This is because of the fact that power systems via renewable types of energy produce no harmful gases or fluids that can damage the condition of the environment. It is actually safe to say that you can help save and protect the nature or environment with the simple use of either a wind or solar power system to generate electricity for your home.

? You can acquire some incentives from the government through the use of a residential wind and solar power system. This is really true since the government by now, has a strong campaign against global warming. In light of this, the government has decided to give some benefits and incentives to households, which utilize homemade wind and solar power systems.

Indeed, utilizing a residential wind and solar power system is a great option for you to consider since it has a lot of benefits to offer not only to the human race but to the environment as well. In fact, some of its numerous benefits and advantages were already mentioned above. So, the final decision is now up to you. If you really want to experience the exceptional benefits being offered by homemade power systems then, you should now start thinking about having a wind and solar power system for your home. After all, there is no harm on considering some helpful renewable sources of energy like the wind energy and solar energy as a way to generate electricity for your home.

Solar-Controlled Glass: The Basics

In the age of Global Warming we are all being constantly urged to do our bit in the battle to save the planet. Newly developed solar-controlled glass is an easy an effective way to ensure that your home is eco-friendly. Here’s how it works.

Essentially, solar-controlled glass is glass that is either tinted or has been treated with a coating to restrict the amount of sun-generated infrared radiation allowed to pass through the glass. Ordinary untreated glass can transmit over 90% of the solar energy sent by the sun, allowing your house to heat up and be filled with a glaring light. Glass that is simply tinted or bronzed provides moderate solar control, although having glass with a colour does not always suit every location.

Coated solar controlled glass has various transparent materials applied to the surface. By carefully selecting the coatings the spectrum of solar energy can be controlled to allow some wavelengths through and reflect others. The proportion of light and solar heat can be adjusted to provide a variety of products that meet the requirements of different building types.

In simpler terms, solar-controlled glass lets in a good amount of light, keeping our homes sunny and bright, whilst keeping them cooler in summer, or keeping them warmer in winter. Clever!

The Benefits of Solar-Controlled Glass

The new trend of maximising the use of glass in architecture might be visually spectacular, but gives little thought to the people left living with drastic levels of heat or cold and net curtains to control the constant glare.

Solar-controlled glass allows us to live in natural light, while still being as comfortable as possible, ideal for conservatories. The glass is available in a variety of subtle colours or neutral adding a unique and striking feature to our homes.

All household and commercial glass-needs can be catered for by these glass types and custom configurations are manageable. Solar-controlled glass can also be combined with other performance options, like noise control or self-cleaning glass, for maximum benefits. Toughened or laminated solar-controlled glass is also available, ensuring that your family is both safe and comfortable.

Most importantly, in our new quest to be ‘green’ and environmentally friendly, solar-controlled glass can reduce, and possibly even eradicate, the need to use air conditioners and heaters. This energy saving both reduces our monthly bills and contributes towards a healthier environment.

In this day and age of growing technology, scientists are working diligently to find ways to harness solar energy in order to power the Earth. Producing cars and products powered by solar energy will reduce the emission of harmful gasses and chemicals into the atmosphere. Our Earth is a precious commodity and we need to take care to protect it.

What is solar energy? Solar energy is radiant heat and light that is emanated from the Sun. This light helps to influence the climate on Earth and allows not only humans and animals – but also fish to live. Solar energy has been harnessed for power since the ancient times by humans through the use of different technologies.

The Earth can receive 174 petawatts of solar radiation or insolation in its upper atmosphere. Close to 30% of that is reflected back into space and the rest is absorbed by the clouds, land masses, and the oceans. The spectrum of solar light on the surface of the Earth is predominantly spread across near infrared and visible ranges and a small part in the near ultraviolet. The solar light that is absorbed is able to heat the land surface, atmosphere, and oceans.

Solar energy as well as hydroelectricity, wind, and wave power make up 99.97% of the renewable energy that is available on the Earth. The total amount of solar energy that the Earth’s atmosphere, land masses, and oceans absorbs is close to 3,850 zettajoules a year. Studies show that in 2002 this was more energy in one single hour then what the world would use in a total year.

The amount of solar energy that the Earth’s surface can capture is so large that in a single year it will be twice the amount that we can obtain from non-renewable resources of oil, coal, and natural gas. Because of this consumers themselves are seeking to purchase their own solar energy systems to help save them money and to keep the Earth safe.

The bilinnia of year have been spent to build up protective mechanism of the environ-sphere that support our planet- the ocean, the fist creation of oxygen, and ozone , the breathing out all of the earth growing cover of green plants.

Today ,what have has it become of human in basing a larger part of our energy supply upon atomic energy is bringing down to earth the power that would have never permitted any kind of organic life to develop on this planet . Even thus the first generation of this fire was accidental, the first intention was nevertheless an act of cruelty .beside this, we have forgotten with an uneasiness born of the sense of sacrilege that the first use of this dangerous fire end up wiping out two cities, without care for individual guilt, or innocent , man or woman , you or aged . the building of atomic technology has was never due to compulsion of war but the fear of energy depletion , but today the development is hazardous to all of us in a new way including creation of risk of reversible damage to mankind’s genetic inheritance.

Prospect of peaceful nuclear power generation:

Energy released from fusion – plant in this generation are using the same processes used for the first atomic bomb –here only one percent of the uranium oxide is used up, it has the risk that the whole chain reaction will end in an uncontrolled released of radioactivity is offset by insertion of absorbent elements which slow down the reaction and the limitation of this process is the scarcity of U235. The breeder reactor-This process bypass 1 percent use of uranium oxide up to 80 percent- exploitation rate, thus here we have advantage of fuel , the real cost of nuclear program depends on the installation and safeguard . The fusion reactor-this involve the transfer to earth of the sun processes, the vast release of energy achieved by the fusing of nuclei within the superheated hydrogen plasma of the sun’s core. Here the fact is that the technical difficulty in term of containment of huge thermal release is still enormous.

These are systems let us look at the advantages:

· Fission reactors or so called light- water cooled system are less pollutant and they have competitive cost.

· The breeder rectors are even more economical, but full of uncertainty and there is ongoing research on the technology.

Lets us look at the hazards

Both fission and fusion provide high thermal pollution – here they provide no advantage over conventional plants. Fission and fusion posed problem of radio activities – even thus they say they make effort to contain the entire radioactivity given off during nuclear generation with hermetically sealed containers. A lot of seepage occurs during storage, transport, in the cooling water, in release gases, in the cleaning of fuel elements and disposal. Problem of disposal- most radioactive materials have half life of 100 years , disposal cost a lot , and even where to dispose is a big treat to the environment the is no sink on this planet. Workers and community exposure to radiation – the noxious nature of the radioactive material has fundamental difficulties that there is no safe threshold of radioactive under a wide variety of condition – age, exposure, metabolism- create genetic damage or cancer.

Now the fundamental question is the dabbling into nuclear worth the danger? Does worth it for community to regard death as a reasonable risk in return for some suppose good in quite clear? Any carelessness, any casualness, any calculus based upon inward- looking national advantage and prestige or a quick profit gained by some smartly turned commercial deal is utterly unthinkable in this context. Time is actually calling for us to seize to make simple calculation of gain or convenience, but to confront our survival and tat of our children and grandchildren and whole human race.

Communities need to apply common sense to more detail issues. Communities should protest that closed to nuclear station should protest, because nuclear leak of lethal radio activities (whose spreading in all direction is quite fast) to an urban region or population could lead disaster even point form degradation over years. Community that already has nuclear power plant should demand the right to set monitoring sytem to lower dose and contaminated rate. Community should demand right to be informed about new technology deployment and measures for existing system.

Now I will make a brief quantitative summary under technical- economic- social and political (dominate most) platform

Design =plant size (-), power (-) since large fixed mass mc

Production= (-) more complex

Operations= maintenance and repair (-), no refueling (+), does not need oxygen (+)

Economics = capital (-), revenue (-), wage (-)

Social = owner, crew, health (-)

Political = national (-), accident (-), prestige (+), military (+)

You might wonder why there are no nuclear ship – there was, the first one that was built (m.v. savanna) was rejected in every port of the world, end up in a museum.

We have already made error regarding air and water as free goods and have, if we have to treat the risk of rising cancer, genetic mutation we may get more power and pay more for safety at the expense of degenerating population. In any case, it does not make much difference from military insanities of multifold nuclear overkill and all the atomic gadgetry of mass killing from which a recognizable human species will hardly survive. It important to let go this destructive temptation, those who have it should destroy it and those who plan to have to should forget about. It is only with love, establishing loyalty, and trust respect, justice can we us nuclear energy, the situation of the planet with misplaced trust here and there has complicated energy issue. It is true we have 6 billion inhabitant of this planet and we need energy, the fossil is envisage to be depleting , thus to keep 10 billion people alive in this planet , atomic energy seem to be favorable likely answer, but yet the disadvantages supersede the advantages . However, we still other options ort alternatives – we large reserve of coal than can last for another bilinium. With the abundant existence of water in this planet can use hydropower and wave power, solar energy, fuel cell, geothermal taping of internal earth heat
