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.

Green Living

Going Green isn’t only about changing a light bulb or buying expensive products. Going Green is a way of life and has to do with our holistic approach to life. Our careful choices immediately have an impact on your health and, essentially, the health of our planet.

But don’t think that little things don’t matter! It just takes a bit of effort to go a long distance. Here you can find some tips to make your life a little greener, too.

Are you really serious about Green Living and Going Green? Then, consider taking some big steps, what about changing your career and contributing to the development of clean energy technologies? If you don’t have a high school diploma, you can get your GED diploma (even if you just study online) and apply for a green career, it might be something for you! Check out these  free online classes for the GED on the BestGEDclasses website

Clean energy careers are hot, they are favorite choices of career for many students who are attracted by many well-paid and in-demand jobs. Clean energy job would make you feel good and will benefit our mother-earth.

Climate Change and Global Warming

Energy

We all are concerned about climate change and the effects we already experience. But what if Global Warming is a natural phenomenon? Many people claim that on our planet, warmer and cooler periods have occurred for as far back as we are able to determine.

Periods of Global Warming have occurred some 100,000, 200,000 and 300,000 years ago, and scientific data has been obtained from proxy sources including sediment layers and rocks, ice cores, tree rings, and coral reefs. Compiling all these data allows us to determine temperatures millions of years ago.

Renewable Energy Popular?

Energy

What obstacles keep us from switching to renewable energy?

Stranded Cost: Across the US, we already have been paying some one trillion dollars for the infrastructure for fossil fuels. There are people who say that, if we were to switch entirely to renewable fuels, this huge investment could be ‘stranded’, unless we would find ways to include it. This is why there is opposition against switching to renewable fuels as this would create a huge economic disincentive. There are others who argue that abandoning this existing infrastructure gradually would be a lot cheaper than giving it up immediately.

Upfront Cost: There are renewable sources (wind power, hydropower, and geothermal power) that are currently (practically) competitive with fossil fuels, but solar energy continues to be pretty much more costly than coal-based electricity. The budgetary mechanisms to that allow renewable fuel systems to be paying for themselves in a natural way simply do not exist yet.

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:

What is Solar Power?

Energy

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
