Cheap and Easy Ways to Use Solar Energy

Alternative Energy

Harnessing the sun’s energy makes sense because it is clean, green, and saves money in the long run. But the reality is that the cost involved with installing panels and collectors is still out of reach for the vast majority of homeowners. Fortunately, there are some cheap and easy ways to make the sun work for you.

Passive Solar
Passive solar means simply using or blocking the sun’s rays to heat or cool your home. This means that using your window coverings wisely can save you a ton on your power bills. Simply closing or angling your blinds to keep direct sunlight out can drop the interior temperature by 10 degrees. Try closing the window coverings on the south side of your house when you leave for the day during the summer months.

Without the sun’s hot light shining in the windows, your air conditioner won’t have to work as hard. And in the winter, of course, doing the opposite can help heat your house. There tons of great looking blinds, awnings, and window films to help you harness or block the sun’s powerful rays.

How Will Solar PV Businesses Benefit From The New Incentives?

Alternative Energy

The Claymore MAC Global Solar Energy Index ETF, TAN, had fallen 78% over the past years, but they’re back. Most listed solar companies had fallen from 50% to 87% over that period, but a bright spark, however, was the passed economic stimulus bill which started boosting demand once again. With the extension of the Federal 30% tax credit and the removal of the $2000 cap, homeowners will see the price of solar PV get much more affordable.

And, for commercial developers of solar facilities, the new bill has provisions that would allow them to take the 30% tax credit as a grant instead. Some of the companies best positioned to ride out the challenges of this year are the big market-leading companies with adequate cash in hand. US manufacturer First Solar is one of these companies.

Wave Energy

Alternative Energy

Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants, and water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density.

To date, there are only a handful of experimental wave generator plants in operation around the world. The articles on this page explore the world of wave energy and its possible applications.

Wind Turbines – What Are They and What Can They Do for You?

Alternative Energy

When you hear the words wind turbine, you probably think of gigantic structures that generate electricity for big companies. Wind turbines actually come in a variety of different sizes and types. You could use a smaller version of the huge ones in order to generate electricity for your own home or business. There are tons of different ones to choose from and depending on how much electricity you need, you may be able to find the right one for you for less than you think.

So how does a wind turbine work? They generate electricity from the wind. Wind turbines most often come in the form of a windmill and are able to seemingly make electricity from thin air. In fact, they do! With a geared power train, wind turbines are able to generate lots of electricity. Some people favor these machines more than solar panels. They are cost effective and able to pay for themselves within a few short years.

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:
