How Solar Panels Work and What They Cost

Alternative Energy

Basically, the solar panel is a device used to generate energy. Energy that doesn’t require raw materials and, even better, it’s free and renewable.

Going into further details, solar panels are means of capturing and using solar energy. There are two big types of solar panels:

  • Solar panels used for heating
  • Solar panels which use photovoltaic (PV) cells for producing electricity

Solar Panels Used For Heating

These types of solar panels are used for warming the water or the house. Their working process, very much simplified, is the following: the panels capture solar heat and transfer it with the help of tubes to a water flow.Continue reading

Green Living for Beginners

Alternative Energy

Now here are a few ideas for how you can check yourself, without wrecking yourself – or others. And please, if you simply cannot manage to disabuse yourself of your bad habits of thinking, do us all a favor and keep your damn opinion to yourself. When we want to hear from you, we’ll ask you to chime in, but let’s be clear about one thing: this here energy, environment and resource thing is MY generation’s problem to fix, and the same people who got us into the mess will not be the ones to get us out of it. That much we know for certain. So my suggestions:

1. Support the development of clean energy technology. If you feel so inclined, work to get a job in this sector yourself so you can actively contribute to the building of real solutions. Energy efficiency and using less energy is all fine and good, but ultimately we need to have renewable sources of energy, transportation systems that don’t rely on rapidly depleting resources, and ways of managing our garbage and other inevitable excrement of society that doesn’t foul up the air we all breathe and the water we all drink. The only way these jobs, the ones we really need, are going to come into existence, is if we work as hard as we possibly can to create them ourselves.

Global Warming Causes

Alternative Energy

For quite a few decades, researchers have been curious about the causes of global warming. They researched numerous factors including the natural climate cycles and activities that have an effect on our climate. Recent studies took a closer look at some surprising things that they considered to be causes of global warming.

– Methane gas release in areas of wetlands and the arctic tundra. Methane is identified as one of the greenhouse gasses that are responsible for trapping heat bring trapped inside the atmosphere.
– Natural Climate Change Cycles tend to occur every 40,000 years.
– An abundance of volcano activity leads to an huge increase of greenhouse gasses.
– Sunspots and their impact

Green Living – Homes

Alternative Energy

In a cultural sense, we seem to have arrived at the point where we started out from a few decades ago in terms of constructing houses for the future. In the 70’s and 80’s, moderate and affordable houses turned into disproportionate and enormous living quarters. It didn’t take long, though, that many people started to recognize that the toll that came with living in excess was substantial. These days, including environment friendly sustainable engineering and techniques into the construction of our homes has become not only acceptable but desirable or even necessary.

As a population, we have come to understand and maybe even welcome the theory that building and living in a modest, sustainable way is best for us and for generations to come. Home builders today are applying increasingly more renewable and environmentally conscious techniques to meet many home owners’ requirements. We have seen a dramatic shift in the principles of construction, and homes for future years are being constructed today with a lot of green technologies. Here are a some examples and possibilities:

What is Solar Power?


How much of our energy is coming from the Sun?

In Direct sunlight, the sun is providing around 90 watts per square inch at the surface of the Earth, or 1000 watts per square meter. The intensity that this refers to is what energy scientists call 1 sun, and is sufficient to power ten 100-watt light bulbs, or fifty 20-watt fluorescent light bulbs. As opposed to what is sometimes claimed by solar energy opponents is solar power not at all weak or diffuse.

The amount of sunlight that falls on even a tiny portion of a home’s roof is in general actually already enough to take care of all the home’s energy needs. Or said in another way, if we would cover not even 1 percent of all U.S. land area with solar power panels, we could be providing all of our current energy needs.Continue reading

What is Energy and Forms of Energy


Energy, in all its forms, belongs to the most fundamental elements in our universe.

We are using energy to live or to do work, our cities are lighted by energy, our vehicles are powered by energy, as are trains, planes, boats, and rockets. We use energy to warm our homes, to cook our food, to play our music, or to watch television. Energy is needed to power a tractor on a farm or to allow machines in a factory run.Continue reading

Nonrenewable Sources of Energy – What are they?


Nonrenewable sources of energy are the ones that have a pre-existing finite amount of ‘fuel’, and by “fuel” is meant any kind of substance that is storing energy. Natural gas, gasoline, uranium, kerosene, and firewood, all these substances are ‘fuel’ examples. And of these ‘fuels’, firewood is the only renewable is this listing. Here are the most common nonrenewable fuels:

Fossil Fuels: Oil, Coal, and Natural Gas – These fossil are what is left over from animals and plants that were living several millions of years before us. This is why they are called ‘fossil’.  All these fuels are ‘carbon-based’ meaning they are consisting mainly of elements that contain carbon and hydrogen coming from these ancient animals and plants’ bodies. Oil is a fossil fuel in liquid form (where each molecule contains several carbon atoms), natural gas is fossil fuel in gaseous form (where each small molecule contains just 1 or 2 carbon atoms), and coal is fossil fuel in solid form (each molecule contains many carbon atoms).Continue reading
