Green energy refers to the use of power that is not only more efficient than fossil fuel but that is friendly to the environment as well. Green energy is generally defined as energy sources that dont pollute and are renewable.

There are several categories of green energy. They are anaerobic digestion, wind power, geothermal power, hydropower on a small scale, biomass power, solar power and wave power. Waste incineration can even be a source of green energy.

Nuclear power plants claim that they produce green energy as well, though this source is fraught with controversy, as we all know. While nuclear energy may be sustainable, may be considered renewable and does not pollute the atmosphere while it is producing energy, its waste does pollute the biosphere as it is released.

The transport, mining and phases before and after production of nuclear energy does produce and release carbon dioxide and similar destructive greenhouse gases. When we read of green energy, therefore, we rarely see nuclear power included.

Those who support nuclear energy say that nuclear waste is not, in fact, released into our earths biosphere during its normal production cycle. They stress as well that the carbon dioxide that nuclear energy production releases is comparable, in terms of each kilowatt hour of electricity, to such sources of green energy as wind power.

As an example of the green energy production the average wind turbine, such as the one in Reading England, can produce enough energy daily to be the only energy source for 1000 households.

Many countries now offer household and commercial consumers to opt for total use of green energy. They do this one of two ways. Consumers can buy their electricity from a company that only uses renewable green energy technology, or they can buy from their general supplies such as the local utility company who then buys from green energy resources only as much of a supply as consumers pay for.

The latter is generally a more cost – efficient way of supplying a home or office with green energy, as the supplier can reap the economic benefits of a mass purchase. Green energy generally costs more per kilowatt hour than standard fossil fuel energy.

Consumers can also purchase green energy certificates, which are alternately referred to as green tags or green certificates. These are available in both Europe and the United States, and are the most convenient method for the average consumer to support green energy. More than 35 million European households and one million American households now buy these green energy certificates.

While green energy is a great step in the direction of keeping our environment healthy and our air as pollutant free as possible, it must be noted that no matter what the energy, it will negatively impact the environment to some extent.

Every energy source, green or otherwise, requires energy. The production of this energy will create pollution during its manufacture. Green energys impact is minimal, however.

The Kyoto Protocol is a UN-led international agreement reached in 1997 in Kyoto, Japan to address the problems of climate change and the reduction greenhouse gas emissions. The Kyoto Protocol went into force on February 2005.

Signatory countries are committed to moving away from fossil fuel energy sources – oil, gas, and coal, to renewable sources of energy such as hydro, wind and solar power, and to less environmentally harmful ways of burning fossil fuels. Greenhouse gases such as carbon dioxide, methane and nitrous oxide are mainly generated by burning fossil fuels. Higher levels of greenhouse gas emissions cause global warming and climate change.

The Protocol commits 38 industrialized countries to cut greenhouse gas emissions by 2008-2012 to overall levels that are 5.2 percent below 1990 levels. Targets for greenhouse gas emissions reduction were established for each industrialized country. Developing countries including China and India were asked to set voluntary targets for greenhouse gas emissions.

The Canadian target for Kyoto is to reduce by 2012, greenhouse gas emissions by six percent below their 1990. The United States did not ratify the Kyoto Protocol, and in February 2002 introduced the Clean Skies and Global Climate Change initiatives, in which targets for reduction in greenhouse gas emissions are linked directly to GDP and the size of the U.S. economy.

Trading of carbon emissions is linked to a program called Cap-and-Trade. Understanding this concept is necessary to begin effective trading. A central authority (usually a government or international body) sets a limit or cap on the amount of emissions discharged into the atmosphere. Companies that exceed the cap may be subject to fine or regulatory sanction. Therefore, those who find they cannot meet the conditions of the cap will look to buy credits from those who pollute less.

Many older established companies are forced to spend considerable sums of money modernizing plants. In many instances this takes time, usually years to achieve. In contrast to new generation technologies which are not faced with up-grading facilities to comply with 1990 emission standards. Trading emission credits is a way for low emission companies such as wind farms to sell credits to benefit higher emitting companies. Cap-and-trade programs ultimately aid in being a net benefit to the host country by enabling it to meet it’s commitment to the Kyoto Protocol Agreement.

From the very beginning, this first phase of the European Union Emissions Trading Scheme, or EU-ETS, was intended to be a learning period to work out the kinks and entice major greenhouse gas emitters on board.

On January 1, 2005, the EU-ETS came online with the cap-and-trade program covering approximately 12,000 installations including electricity production and some heavy industry. These 27 member countries of the European Union represents roughly 45 percent of total European CO2 emissions.

Now three years later, amid a flurry of expectations and public controversy, the European Union has credible results to back up its claim of success. Recently, a Massachusetts Institute of Technology analysis of the EU Emissions Trading Scheme (ETS) affirms that despite rather unstable beginnings, the system has been an unprecedented success. More importantly, it opens the door for skeptical countries like the United States to follow suit.

The United States would have been required to reduce its emissions 7 percent below 1990 levels had it accepted ratification of Kyoto. Instead, U.S. emissions have now risen more than 16 percent between 1990 and 2005.

The Bush administration and Republican lawmakers opposed to emission caps have been touting the Asia-Pacific Partnership on Clean Development and Climate, which consists of Australia, China, India, Japan, South Korea, and the United States. The aim of the initiative, which began in 2005, is to foster cooperation on ways to improve clean energy development and lower emissions without global mandates. But since the initiative started, the United States, India, and China have come under increased domestic pressure to move toward mandatory emission controls. California is among several U.S. states that have entered into partnerships or passed laws for controlling greenhouse gases ahead of the federal government, leading to a showdown with congressional lawmakers. Major U.S. cities have also instituted a host of policies designed to cut greenhouse gases.

Without the United States entering into a binding commitment, it is feared that several developing countries which have not yet signed plus some Kyoto signatories may be unwilling to agree to additional international commitments.

Fuel Alternatives, the 20th century has built itself mostly around energy produced from nonrenewable sources with harmful emissions, presently much of the world uses oil/gas and nuclear power, and (a renewable source) hydroelectric for power production. In the 1970s, the price of fossil fuels, rose considerably inspiring governments to seek more oil, this solved the problem temporarily now in 21st Century, with the cost of fossil fuels rising higher still, it has sent many of the larger oil companies scurrying to the oil sands project in Alberta. Where there is a plentiful yet hard to get to supply of energy in the form of Bitumen, however with the high carbon emissions from this project. It is hardly a viable option environmentally, with the the high cost of oil and our realization that its carbon emissions cause global warming, this drives consumers and inventors towards renewable energy resources, many areas are being investigated. Fuel Alternative solutions include

* Hydrogen
* Wind
* Garbage
* Geothermal
* Solar
* Tidal

Hydrogen water power is mostly being considered in vehicles, contrary to earlier research it is possible to harness the power of water in various ways, one being separating hydrogen and oxygen atoms and putting them back together to produce energy, this has already been put in action and used in successfully in engines. The Oceans power is being harnessed, by various companies investigating different methods of doing so, some by using turbines that look like large propellers, others have survivable aquabouys floating on the surface, using the up and down wave motion of the to drive turbines and generate power is then sent to a central grid. In tropical areas near the equator the surface of the ocean’s water becomes heated, an innovative group of engineers have designed a method of harnessing this heat energy into power using a generator on a floating platform and some very large pipes, to make electricity when the water cools its sent back to the ocean to heat up again, always being recycled. Geothermal heat, is that which dwells deep beneath the earth’s service for this method of energy conversion, deep holes are drilled in five or 6000 feet into the earth where it connects with thermally heated water, natural pressure brings his water through the pipe to the station that converts it into power, then sends the water back, to be reheated.

Solar power is one we are all familiar with, having been around for many years, its application is becoming more prevalent as the photovoltaic panels are more efficient. These days wind power from giant wind turbine farms goes to producing electricity, rather and powering a mechanical grinding mill, its then sent to a central collecting station, now there are personal wind turbines around perfect for places where bylaws allow. Wind turbines have been in place, especially in Europe for at the least 25 years.

Another method of energy conversion has been devised, collecting methane from deteriorating garbage, that can be turned into energy, then it can be used in all kinds of applications. With all these energy-saving, energy collecting devices, and reusable resources, the future can be less reliant upon fossil fuels. Energy efficient homes will become a normal necessity as populations increase demand for energy increases, with the demand for food, It is foreseeable that one day, each home can provide its own power, be fuel and water efficient, running with very low carbon emissions algae powered vehicles, solar heated water and wind/sun powered electricity, all running in harmony, what a shame, we wait for conditions to become practically critical in order to implement them.

The old-style electric power stations are an inefficient use of fossil fuels as an extraordinary amount of energy is simply wasted, the cooling towers blow away heat/power that could be harnessed in fact, over two thirds of the energy that is put into them is wasted.

In thermodynamic terms you can run an engine on heat if you have a warm reservoir and a cold reservoir, a heat engine is simply a very conventional system where boiling a working fluid that is then run through a turbine, the turbine is connected to a generator and it makes electricity, after it runs through the turbine, it gets in touch with the cold water and it condenses back to liquid. It’s very simple conceptually and it uses the fact that heated liquid flows to cold to run this engine.”One of the by-products of the condensation is fresh water, if the system is open-cycle, meaning the working fluid is seawater. In a closed-cycle system, which typically uses ammonia as the working fluid, fresh water is not produced, but the size of the turbine can be significantly smaller, reducing capital costs.

Fuel Alternatives one day will not be so alternative.

Today the world is waking up to the use of wood pellets. Being a source of naturally rich biodegradable energy these pellets can be vital once gas and oil fuels have depleted. Here we talk about how wood pellets can be great as a fuel source.

Why it is renewable?

One reason why such pellets are a source of renewable energy is because they are made of wood. While the wood burns the carbon dioxide emissions are very less since the plant would have consumed it during its growing years. This is why even carbon dioxide fossils are being increasingly used in emissions in order to reduce the overall carbon dioxide emissions into the atmosphere.

What are wood pellets?

Wood pellets are basically comprised of wasted sawdust in its compressed form. Today several countries such as Sweden, Northern America, Denmark as well as Austria employ the usage of this form of energy. Currently the UK offers a conducive environment for the use of such wood pellets. In fact these are being increasingly used here as a source of biodegradable energy.

Practical and inexpensive

The main benefit of using wood pellets is their relative ease of use, their cost effectiveness as well as being a source of renewable energy. Many hitherto touted sources of fuel like wind power, tidal power as well as solar energy have incurred criticism from many people because of their impracticality and expensive nature. However the beauty of wood pellets is that these can be employed both for electricity generation purposes as well as for fuel purposes.

On demand biodegradable energy

Another significant advantage of wood pellets is that one can derive energy from them as and when the need arises. This is in direct contrast to energy sources like solar power where it is dependant on the weather conditions. Best of all it is a source of easily renewable energy that is relatively cheaper than other energy sources.

Better than wet wood

Wood pellets can provide almost as much as double the energy as a wet wood form can! In fact just 1 kilogram of wood pellets can supply heat in comparison to a electric fire of 1 KW that has been on for over 5 hours! The way the wood pellets are used is that they are heated inside special boilers which one can use inside the home too. Even in large heavy duty industrial purposes this source of biodegradable energy can be easily used.

So on the whole, the benefits of using wood pellets is significantly large. Apart from being a source of fantastic renewable energy this wood is small in size which means it does not take up too much space. Therefore it offers good portability too! In addition it is a combustible item which has originated from nature itself. Therefore it is completely in harmony with the environment as well. It is therefore time that we as individuals started using this fabulous biodegradable energy source.

Have you noticed your energy bill getting more and more expensive every month? I sure have. Sometimes I almost feel hopeless when it comes to paying my bills on time. My energy bill just keeps on getting more and more expensive each month! But you know what, I found a great way to cope with the rising costs of energy. I’ve created my own source of energy, and I’m willing to tell you how I did it in just 3 easy steps!

1) Researching Renewable Energy

The first thing that I did was research ways to create my own source of renewable energy. Just like you I was eager to learn about the possibilities of making my own energy and saving some money on my electric bill. What I found was that I had two options when it came to making my own renewable energy. I would either have to build a wind turbine or solar energy generator. Both of these energy sources have something in common. They are forms of green energy. This means that they are cheap, renewable, and clean.

I’m going to be honest with you. After discovering that I was going to have to make my own wind turbine or solar panel I was extremely intimidated. I thought to myself, “How in the world am I going to be able to make my own green energy source?”. And this led me to the second step…

2) Do You Have Directions?

Ok, so at this point I had come to realize that I was going to have to build my own natural energy source. So what did I do? Well, I did a little more tedious research. I did what everybody does these days, I asked Google. After hours of searching for phrases like “how to make your own energy” and “how to build a wind turbine” I was left very irritable and discouraged. I found that manually researching something like this was not only tedious but also unreliable.

That is until I came across a little hidden gem…

3) The All Powerful Guide

Truth be told I did waste many hours researching only to be left with garbage. But I did gain a very valuable tool that helped me successfully build my own green energy source. I came a across a DIY homemade natural power guide. In it I found every single piece of information that I needed to build my own natural power system. It was filled to the brim with detailed diagrams, pictures, schematics, secret tips, you name it. It was all there.

And guess what? I was able to build my own natural power system in just two days. Want to know how much it cost me? The total cost of everything was less than $200! This isn’t cheap but it sure beats paying $20,000 for a professionally installed green energy source. The best part is that I payed off the initial costs within a month, and am now saving hundreds of dollars every month.

You CAN make your own green energy source. All you need is the right resources. If you believe in yourself and you believe in saving money on your energy bill every month, then I highly recommend you click the link below. You will learn about the specific DIY green energy guide that I used. Why spend dozens of hours on tedious research when all you need is right in front of you?
