Some people may not want to admit it, but the world is slowly moving towards an energy crisis. Non-renewable resources such as fossil fuels are much closer than people think to becoming extinct. We have always known that the everyday energy we use is not unlimited, yet it is constantly taken for granted. Oil, gas, power, even water has limited availability. Yet, we have not taken nearly enough precautions to deal with a very real threat of an energy crisis. When I say ‘we’, I am not referring to the governments of the world, but to all of us, the common people. We are the ones who can make a difference.

To neutralize this crisis, it is important that we learn to reduce our dependency on energy sources that are non-renewable and start focusing on energy solutions that can provide us with a continuous source of energy that will not exhaust any resources. There are 3 main sources of energy which fall into this category: hydro energy, wind energy, and solar energy.

First, let’s look at hydro energy.

Hydroelectricity is the most widely used form of renewable energy in the world. It is typically generated on a large scale by way of hydroelectric dams. Although it is indeed a renewable source of energy, hydro energy comes with some drawbacks. Hydroelectric projects have been known to have negative effects on surrounding aquatic ecosystems. One example, is there are studies that have shown that dams along the Atlantic and Pacific coasts of North America have reduced salmon populations due to their preventing access to spawning grounds upstream. A major disadvantage to hydroelectricity although rare, is the risk of dam failure. In Southern China, the Banquio Dam failure resulted in the deaths 171,000 people and left millions homeless. Although it is an effective source of renewable energy, it is not as environmentally friendly as the other 2 main sources of renewable energy, wind and solar power.

Let’s look at wind energy.

Windmills have been around for thousands of years. They are older than electricity itself. In pre-industrialization times, they were used to propel sailboats and ships, they were used to pump water, and they were used as a means of natural ventilation in buildings.

Wind power has many advantages: It causes absolutely no pollution whatsoever. It consumes no fuel and has practically no effects on the environment at all. Wind energy can help generate tonnes of megawatts of electricity. When employed at home, it can help do away with conventional power sources which will reduce your electricity bill and can even eliminate it altogether. Wind power is an excellent source of continuous, renewable energy.

Finally, let’s look at solar energy.

Solar power is by far the most available source of continuous, renewable energy on the planet. It is easily capable of providing the world’s total current energy demand many times over. Solar power solutions at home are another way of dramatically cutting down power bills or even completely eliminating them altogether. Also, solar power has no effect on the environment whatsoever. It is the most environmentally friendly source of energy in the world.

Setting up your own wind and solar system not only benefits you by cutting down your power bill, it benefits everyone by helping to stop the dependency on non-renewable resources.
Wind and solar power solutions at home are not as costly as one might think either. Even if you are on a budget, you can easily set up a wind and solar system at home.

International Energy Agency defines renewable (re-new-able) energy as the energy derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources such as sunlight, wind, rain, tides and geothermal heat.

Sun is the ultimate of all the source of energy. Renewable energy can be obtained from the same source for a long period of time without depleting a source. For example solar energy can be obtained continuous from the sun without depleting the source. This is in contrast to the non-renewable or commercial forms of energy such as oil and gas. The more they are extracted, the more will be the reduction in source.

A growing body of scientific evidences has demonstrated that the heavy reliance on fossil fuels or commercial form of energy is destabilizing the climate. Emission resulting from the combustion of fossil fuels such as coal, oil, and gases are responsible for the emission of Greenhouse gases. Green house gases (GHGs) in turn are responsible for heat imbalance of the earth resulting climate change. Climate change is the burning environmental issues. On the other hand, energy produced by renewable sources greatly reduces greenhouse gas emissions relative to energy produced from burning fossil fuels.

Global environmental concerns, the depletion of the earth’s finite resources and economic considerations are all incentives to interest consumers in renewable. Although renewable cannot yet replace all existing energy sources, they can supplement power generated by utilities and increase the diversity of our energy supply. Global climate change due to pollution and the effects of pollution on the environment have become major environmental issues since the Rio Summit in 1992.

One of the greatest benefits of renewable energy is its potential to provide clean sources of electricity even to remote populations. Although many people around the world do not have an economical connection to an electrical grid, renewable energy technologies can capture natural sources of (electrical and heat) energy in non-conventional locations and in non-conventional ways.

Country policy on tax exemptions, grants and aids are different depending on the capacity of the government. Renewable energy resources are considered as one of the major components for a sustainable future in order to continue and heighten economic as well as industrial activities in the country.

Government can invite investors internationally and locally. The country is represented by the government, specifically the president, wherever he goes. Of course, the government will showcase the best of what the country could offer. Another is that the government opens an international fair once a year. For this year, Korea is hosting an Environment technological fair in Incheon. It will showcase Korea’s finest companies that offer environmental management, clean energy and waste and pest control. Truly, this environment technological fair will open local Korean renewable energy companies to the global market.

Allow the government to invest on your company’s bright idea. Sustainable power could be the new driving force of the country’s economy. The U.S. and China are currently taking the next big step towards alternative energy. They are planning on stimulating the economy towards clean energy. Government investments may guarantee a higher chance of stabilizing yourself as a renewable energy company. Maybe in a few years you would be able to stand on solid ground on your own.

Green energy is for sustainability and not luxury. China’s endeavor to continue providing electricity for the world’s most populous country has stated that providing clean energy for 1 billion people would increase its role in the global stage. Investing on with this perception in mind would strengthen China as a whole international commerce, preventing and combating pollution caused illness towards a more sustainable future. Imagine if 80% of the most populous countries would advocate renewable energy usage; it would dramatically decrease carbon emissions in the atmosphere. It goes the same even for countries all over Europe. They plan to boost the usage of sustainable energy by 10% by 2010 for the whole continent.

Government incentives boost company performance big time! China leaning towards renewable energy companies and the continuous progress is all thanks to government incentives. In 2005, a law is passed on China regarding fixed rate tariffs and carbon credits to alternative power companies. Renewable energy marketing is easier and faster with government help best part is, the government would do it for you for free. It is not always that the companies think of human welfare. Clean power companies could take advantage of this opportunity to carry out its mission at the same time make business. Government cash grants, tax credits and special promotions would allow technology development to increase competitiveness as a company. Renewable energy information via government would increase chances of being marketed to a wider audience.

Thousands of organizations and businesses are going the extra mile and spending the extra dollar to buy utility-scale energy from renewable resources. So much so that the United States E.P.A. (Environmental Protection Agency) compiles a quarterly list of the top green power companies from their Green Power Partnership program which came out in July 2008.

Some businesses take diminutive steps towards a green campaign, but these companies are proving their allegiance to a greener environment by voluntarily spending millions of dollars on clean energy.

1. Intel purchased 1.3 billion kilowatt hours of electricity in January 2008. This compensates for 47 percent of the companies overall energy use.
2. PepsiCo purchased 1.1 billion kilowatt hours of electricity in 2007, the equivalent of powering 90,000 homes for an entire year. This accounts for 100 percent of their annual energy use. PepsiCo was named Green Power Partner of the Year in 2007 by the E.P.A.
3. U.S. Air Force has already purchased 9 million kilowatt hours of electricity this year as of July 2008. They have invested in a number of biogas, biomass, geothermal, solar and wind energy providers.
4. Wells Fargo has purchased 5.5 million kilowatt hours of electricity from wind energy providers thus far in 2008. They are also a Green Power Partner of the Year in 2007. More than green energy, Wells Fargo has made a number of other commitments to their green campaign including LEED certifying their buildings and offering online account statements.
5. Whole Foods Market, the past two years has purchased enough green energy to compensate for 100 percent of their energy use, totalling to over 5 million kilowatt hours annually. The company is also investing in multiple other efforts to reduce their carbon footprint on the environment.

Other organizations ranking high on the E.P.A.’s list are Starbucks, Johnson & Johnson and the University of Pennsylvania.

Capturing warmth from wood has been a practice mankind has been carrying out for thousands of years. The easy log fire is a from of wood heat, used for heat plus for cookery. Using wood for heat in the 20th century never really evolved, as fossil fuel alternatives took control of the market. Fossil fuel heating solutions were low maintenance, highly efficient in addition to at the time affordable. Other than the obvious complications by fossil fuels as well as there carbon emissions, there are other issues by means of our faith on these resources to warmth our homes along with cook our food. The first issue is resource. Fossil fuels in the form of oil plus gas are not widely distributed. A few areas of land in addition to sea, hold the majority of the resources which we are practically able to reach. Within the free market, a product or service is worth what ever someone is willing to pay for it. Therefore it is very easy for the oil industry to initiate charge rises. The extra key issue is there simply isn’t sufficient of these resources to meet rising global demand. We have known this fact for many years, yet it is an issue many seem to be happy to ignore.

Learn more about Biomass Heat

To manufacture biomass a more practical and appealing heat choice, requires the raw biomass fuel source to be compressed into pellets. Owing to compression plus moisture reduction the wood is converted into a more proficient fuel in addition to a energy which is easier to deal by. Also, as all biomass fuel pellets are the same shape as well as size, the same pellet burner depending on the burn pot design can use a wide selection of biomass resources automatically. This is important, because we cannot simply rely on one biomass resource for our fuel needs. Woody wood is part of the solution, but many of the woody biomass resources simply grow too slowly to replace the resources at the rate of consumption. This has therefore led into a great deal of research on energy crops such a miscanthus, reed as well as hemp plus faster growing woody biomass species such as short rotation coppice willow.

Read more about Wood Pellet Machines

Biomass log incineration wood boilers in addition to stoves have been used a extra warmth source for some abode owners, yet very rarely relied on a the main warmth source. The easy reason is work load and poor efficiency. Loading the fire at an acceptable rate with logs would just take up too much time. Pellet burners can feed them selves automatically with energy pellets, by one full hopper load lasting at least a day. To make quality pellet fuels, requires the correct gear along with the correct raw materials. The three key pieces of gear are the hammer mill, dryer in addition to pellet mill. Through this equipment the key processes are size reduction, moisture reduction and particle compression into pellet form. To produce a quality pellet from any raw material requires the correct particle size, correct moisture content plus correct heat. Heat is often a very over looked are, yet is crucial. If the heat is not ample the organic binding abilities of the lignin will not work, plus temperatures which are too high will changes the raw matter in addition to create equipment issues.

More information on Renewable Energy

Renewable energy is a form of energy that can be generated from a number of different natural resources. These renewable resources come from wind, water, rain, sunlight and geothermal heat. Currently around 20 per cent of the world’s energy comes from the renewable energy sources. The vast majority of this comes from burning wood. The second most common form of renewable energy that is in use in the world today comes from hydroelectricity which provides three per cent of the world’s electricity.

One form of renewable energy that is becoming popular in the world today is that of wind power. Unfortunately the problem with wind power, which makes it most controversial, is that they require a great deal of land and a very unsightly and may be damaging to the local environment. However, they can also be built at sea in certain cases, which is more effective and has less of an impact on the environment.

Hydroelectricity is derived from water. Examples of this include water wheels and water mills. One of the best things about hydroelectric power, is that it is effective and relatively cheap to run. These days and supplies 19% of the electricity and the whole world. There are a number of things that can supply hydroelectricity such as tidal power and wave power.

Another popular form of renewable energy is of course solar power, which is derived from sunlight reflected on to solar panels and converted into electricity. It is quite common these days in certain households, where people have their own solar panels installed and can sell any electricity that they generate back into the grid. So, not only is it an environmentally friendly form of energy, but it is also economically viable for the people who use it.

Another form of renewable energy is biofuel, which is derived from recently dead biological material, as opposed to fossil fuels which come from organic matter left by creatures and plant life long dead. The technology that utilizes biofuel is rapidly becoming more popular, with a number of flexible fuel cars starting to appear on the market.

Finally, geothermal energy is another form of a highly effective renewable energy. This type of energy comes directly from tapping into the heat of the planet itself. Unfortunately building geothermal energy power stations is not cheap, but they are cheap to run and they produce a lot of electricity.

The market for renewable energy is rapidly growing, especially the wind power industry, which is currently experiencing a remarkable 30 per cent annual growth rate. In addition to this, or more people are getting solar power panels installed into their homes.

It is refreshing to know that in these times of rapidly growing population around the world and an environment that is becoming increasingly endangered, that governments and people are starting to do something about the problem. As technology continues to advance, one would hope that we can expect to see even more options with regards to renewable energy and a much more frequent use of it.

With just a little bit of research, one can quickly determine that there is a strong and growing groundswell of interest in renewable energy. Leaving politics out of it, many people are simply interested in making their homes more energy efficient and thereby saving money on heating and cooling bills.

Renewable energy generally includes solar power, wind power, and biofuels. For all categories, there are ways to integrate them into your daily life and into your home to make yourself more energy efficient. These changes will certainly save you money over the long run–and in some case in the short term—but they will also help reduce the massive strain that is being placed on the planet in general.

There are a large number of companies, both large and small, that advertise their specific product or service that fits into the renewable energy industry. There are a great number of businesses that manufacture, install and repair all types of solar panels. Likewise, there are a corresponding number of businesses that sell, service and install systems designed to capture wind power. Still more companies are out there manufacturing and selling various forms of biofuels. Biofuels include bio diesel and ethanol. There are also a very few companies engaged in research and development of hydrogen furnaces which run on biomass, often barnyard waste. While all these companies are in business to make money, the combined effect of what they are selling and producing is a positive one for the environment. Renewable energy is an undeniable fact of life for us now, and we all have a form of social responsibility to do our part to advance it into the mainstream. Regardless if the motivation is purely financial—to either make or save money—the end result is the same; a reduction in the emissions and pollution produced by traditional fossil fuels, and a cleaner, more sustainable environment and economy.

Trends toward renewable energy are taking hold on a more widespread basis every day. One will hear more frequent mention of terms like “green construction” or “green companies”. These terms refer to building houses in an environmentally friendly manner, making as much use of renewable energy technology as possible and to businesses that have adopted an organized and serious policy to reducing their environmental impact through use of renewable energy.

Renewable energy has become such a popular subject, that it is seen as a constant theme in contemporary media, including major movies, TV programs and in music. The growing awareness and concern with environmental issues is fueling the fundamental shift toward being more environmentally conscious and toward using renewable energy whenever possible. There is still much pollution and waste in the world today, but there has never been such a high and growing level of awareness and motivation to change our fundamental lifestyles in order to save and cure our climate. Renewable energy is a fundamental piece of the puzzle for not only a healthy planet, but a healthy life as well.

Green energy is referred to as the method of generating power. Most of the time this is known as electrical power which is acquired through resources that are renewable. Green energy can be compared to that of fossil fuels. The emissions from fossil fuels work by creating toxic hydrocarbons which cause us to become ill. The water, wind and sun are alternative energy sources.

When green energy is produced from the sun, we call this solar energy. Solar energy is retained through the use of solar panels. While there are two different types of solar panels, each one uses technology in creating new energy. Solar water heaters are referred to as new energy panels which absorb sunlight and then transfer this to water by heating it. After this, photovoltaic panels work by transforming the radiation into electrical energy. To get the best efficiency through the use of green energy, homeowners are advised to install the panels on top of the roof so they face south at 30 degree angles horizontally. They should never be placed near shady spots or around trees, buildings or chimneys.

One of the more popular sources of green energy are the use of solar energy systems which heat water. When solar panels are connected to a hot water system of a house, these panels can supply in excess of half the water needed per year. Solar collector of choice are typically flat plates or tubes.

For many years, wind has served as a great source of alternatate energy. Originally, the purpose of wind energy was to help pump the water at grain mills. There have been two major improvements in wind turbines since then. The use these wind turbines has resulted in capturing wind to generate electricity within high wind areas. In California, there are many wind turbines on hills. The electricity generated from these is exported for local grid use and standalone applications.

There are enormous potentials in the use of wind energy onshore and offshore when it comes to farming. This form of energy is the cleanest and safest of any method of renewable energy. The UK has the largest source of alternative energy around. In the UK, they are using small batteries which charge the wind spectrum along with wind farms. The wind farms are successful in producing large amounts of electricity. Wind only produces about 1 percent of the world’s entire green energy. The potential is much greater of how much could actually be produced. The percentage of use should drastically change within the twenty years because of rising energy costs. It is not complicated to produce wind energy from wind.

Neither wind or solar energy produce any pollution chemicals or emissions into our environment, which is quite obvious. The only draw back of using this type of energy is how some people find the appearance of wind turbines to be very unattractive. There are others who find the appearance of wind turbines very attractive to the eye. It’s all a matter of opinion.

There is increasing pressure on the IT industry to adopt green business practices by making use of renewable energy. This pressure not only comes from outside factions such as environment organisations, but from within the industry itself, as the global energy crisis threatens spin out of control and send the cost of power soaring. Data centres are notorious power drains, which makes them the most obvious starting place when it comes to addressing renewable energy.

According to John Timmer from Ars Technica, set up costs, running costs and stability are three of the most important factors in determining the credibility of a power source. Timmer believes that renewable energy has the edge over carbon or fossil fuels because, even though the initial set up costs might be higher, the running costs are significantly lower than traditional energy sources. In addition, the price of renewable energy isn’t likely to rise with demand, which means that running costs will remain relatively stable. Renewable energy is also less likely to suffer from periodic interruption owing to political instability or controversial world events.

As renewable energy becomes achievable, location will become an important determining factor in building data centres. We have already seen Google, Microsoft and Yahoo! choose the Pacific Northwest in the US for some of their data centres, so that they can benefit from the region’s use of cheap hydropower. Upstate New York has also become a popular site for data centres, as it makes use of hydropower from Hydro-Quebec.

While hydropower is relatively stable and constant, one of the major problems with other renewable energy sources is that they are only periodically available. The sun only shines for a limited number of hours per day and the wind doesn’t always blow, which means that the storage of renewable energy is of paramount importance. This is where hydroelectric power has the advantage, as storage systems have been in use for a long time already. Energy (in the form of water) is simply pumped into reservoirs during off-peak hours, which is then used when demand begins to climb.

Hydroelectric power systems have one major disadvantage, however, and that is the fact that they make use of fresh water, which is not always in abundant supply. Advances in desalination could play an important role here, however, by neatly circumventing the problem.

Techniques for storing solar energy have also been used for years, which makes this a viable alternative for data centres. Another factor that plays into the hands of data centre owners is the fact that the sun shines during peak usage times, so power supply isn’t such a major issue at night.

According to John Timmer and Ars Technica, other options include charge storage, which is still experimental, chemical storage, particularly with the use of hydrogen, compressed air, which requires convenient, airtight geological formations and thermal storage. Iceland currently makes use of a combination of hydro and geothermal power, while an American data centre company claims to use the wind to generate enough power to keep all its systems running smoothly.

However you look at it, the business of renewable energy is big news in the world of IT. And as companies continue to grow, and demand for data storage continues to rise, renewable energy is likely to play an increasingly important role in IT business considerations.
