The Potential of Wave Power

Experts have been attempting to harness the power of the wave since the late 19th century. As the wind passes over the ocean, it produces waves. There is a direct correlation between the power of the wind and the power of the wave.

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 Aguadora Wave Park (AWP) in Portugal is the worlds first commercial wave farm. The AWP produces roughly 2.25 Mega-Watts of power (enough for 1500 homes) and cost just over 8.5 million euros to deploy (though by 2009 costs are expected to exceed 70 million euros).

Construction and Maintenance

Most turbines require a constant, powerful flow which works in opposition to the very nature of waves, as waves are inconsistent in both direction and power. Powerful storms and the corrosive power of salt water are also adversarial to the construction of a reliable energy collection device. Accounting for the aforementioned problems, a device and its maintenance may become too expensive to be a reliable alternative to coal, oil, biodiesel or even solar power.

Harnessing the Waves

Wave energy collection is, however, remarkably passive. Unlike oil which requires a distillation process before energy can be used, wave energy is automatically converted by turbines. Wave energy is also environmentally friendly, as it creates no atmospheric pollution and has a small carbon footprint (non-existent if not for the manufacture of its devices). More-so, it allows us to utilize a space which has, for most of history, been underutilized: the ocean.

The flowing waters in the rivers and tidal waves can be a good source of alternative energy. With 70% of the earth’s surface covered with water, a great amount of energy can be produced by placing turbines at strategic locations under strong currents. This method of generating electric power is called hydrokinetic power generation.

The Future of Wave Power

According to Trey Taylor Co founder & president of Verdant Power, 4 commercial projects are planned for the next 3-5 years which should have the capacity to produce more than 200 MW when operating in waterways. As great minds continue to tackle the problems of renewable energy, we may see major advancements making wave energy more feasible. Groups such as OREC (Ocean Renewable Energy Coalition), continue to drum up support for projects, but it seems policy makers are a bit uncertain of wave energy’s true benefits.

For now we should focus on implementing wind power and solar power strategies to replace our dependence on oil. It may seem like a panacea on paper, but the reality exposes the truth, wave power is just not ready for wide-scale commercial use yet.

Renewable Energy Systems – Encouraging Developments

There has been a rapid decrease in the supply of conventional energy sources like fossil fuels. This has given rise to more people across the globe making use of renewable energy systems to get cheaper energy for their homes. Renewable energy systems harness the power of nature which means that they are constantly being replenished and that they will never run out. They are also not harmful to the environment like fossil fuels because they do not emit carbon dioxide. This makes renewable energy very attractive to people who are looking towards the future of energy and want to do their part to maintain the environment. Not to mention, people are saving some serious money with alternative energy sources.
Renewable energy systems get their energy from elements in nature such as water, wind, sunlight, and geothermal heat. As technology has improved over the years, it has become easier and easier for consumers and institutions alike to implement the technology. This has also expanded the energy supply for everybody. We will need to utilize these technologies even more so to accommodate the world’s energy consumption continues to rapidly expand.

As of right now, water energy is still the most commonly used type of the renewable energies. And there are actually multiple kinds of water energy. Hydroelectric energy is familiar to most people and it comes from large dams that are located on rivers throughout the world. These dams are usually placed strategically in river systems that have high volumes of water. This moving water provides kinetic energy that is ultimately converted into electricity. Other forms of water energy systems make use of both waves and tides.
Solar power is another form of renewable energy that is really becoming popular. Solar power, obviously, is derived from sunlight. Solar energy has actually been used for a long time well before the modern day photovoltaic cells had been developed. Even in ancient times, people have been using it to give light and heat their homes. In modern times, it is being developed in such a way that it will be able to power large numbers of homes. Although there are various solar technologies, the most common and effective one is the photovoltaic cell. A photovoltaic cell contains a special chemical that traps the sun’s energy so that it can be easily converted to electricity.

Wind farms are also becoming fairly popular. The use the kinetic energy of the wind turbines and then convert it to electricity. Geothermal power is another renewable energy system that is already widely used. Geothermal power actually makes use of the heat from deep down inside the earth to produce electricity. This is done in a variety of ways and one of them is harnessing the steam that comes out of fissures from the ground.
These technologies will be developed further and further because it is pretty apparent that they will one day be a necessity when the fossil fuels begin to dry up. You can expect that the renewable energy systems will become even more efficient and effective. And ultimately they will help us rid ourselves of our dependence on fossil fuels. And it can help people save a lot of money on their electric bill right now while helping the environment at the same time.

Facts About Solar Energy Systems

Solar Energy Systems

The use of solar energy or solar panels, has been catching on during tha last year or so. Originally due to the “Go Green” mentality , solar energy and wind turbine was a great way for us to conserve energy and be apart of earth conservation. But the recent boom in home made energy efforts , combined with current economic climate, leads many to believe that saving money is the newest reason for the solar energy upswing.

Solar Energy Help

Solar energy systems are actually not that complicated to build. Fpr the most part you can get everything you need from home depot. For under $150 , many have constructed 2 or 3 solar panels in there backyard, and some have even made small ones for the roof.

Resources for Alternative Energy

Resources for Alternative Energy

There are many different forms in which alternative energy is available.

One of these is solar power. Solar power is driven by photovoltaic cells, and these are progressively getting less expensive and more advanced. Solar energy power can be used for electricity, heating, and making hot water. Solar energy produces no pollution, as its input comes completely from the sun’s rays.

However, much more work still needs to be done in order for us to economically harness the sun’s energy. For the time being, the resource is a little too conditional—storage batteries are needed to be used as backups in the evenings and on inclement days.

Wind energy has become the most-invested-in (by private investors and governments together) alternative energy source for the time being. The great arrays of triple-bladed windmills are being placed all over as “wind farms”, to capture the motion of the wind and use its kinetic energy for conversion to mechanical or electrical energy. Of course, there is nothing new about the concept of a windmill for harnessing energy.

Modern wind turbines are simply are more advanced variations on the old theme. Of course, the drawback to wind energy is…what do you do when there is a calm, still day? Needless to say, during these times the electric company kicks in for powering your home or office. Wind energy is not altogether independent.

Hydroelectric energy is available as a source of alternative energy, and it can generate a substantial amount of power. Simply put, hydroelectric energy uses the motion of water—its flow in response to gravity, which means downhill—to turn turbines which then generate electrical energy.

Needless to say, water is ubiquitous; finding sources for driving hydroelectric turbines is, therefore, not much of a problem. However, hydroelectricity as a source of alternative energy can be complicated and expensive to produce.

Dams are often built in order to be able to control the flow of the water sufficiently to generate the needed power. Building a dam to store and control water’s potential and kinetic energy takes quite a lot of work, and operating one is complex as well,and conservationists grow concerned that it.

Of course, a dam is not always needed if one is not trying to supply the electrical needs of a city or other very densely populated area. There are small run-of-river hydroelectric converters which are good for supplying neighborhoods or an individual office or home.

Probably the most underrated and under-appreciated form of alternative energy is geothermal energy, which is simply the naturally-occurring energy produced by the heating of artesian waters that are just below the earth’s crust. This heat is transferred into the water from the earth’s inner molten core.

The water is drawn up by various different methods—there are “dry steam” power plants, “flash” power plants, and “binary” power plants for harnessing geothermal energy. The purpose of drawing up the hot water is for the gathering of the steam. The Geysers, approximately 100 miles north of San Francisco, is probably the best-known of all geothermal power fields; it’s an example of a dry stream plant.

Renewable Energy Use: What the Average Individual Needs to Know

It has long been observed and proven that nature has already provided man with enough resources for energy—sunlight, geothermal heat, tides, and wind. Because these energy are abundant, in fact, so abundant that they could be replenished perpetually, they have come to be known as renewable energy.

Though extended discussions about renewable energy and its sources can become winded and more complex, every average person interested enough should at least know the basics in order to grasp the concept of how incredibly beneficial these energy sources are.

Man has long harnessed the power of wind and had applied it for practical purposes, albeit in smaller scale such as the power produced in windmills. Current technologies had long converted these simple renewable energy mechanisms to develop wind farms that generate energy supply without the associated risk of pollution. A lot of wind farms have been established in the United States and abroad to generate electricity. This provides proof on the increasing attraction of using wind power as source of renewable energy while decreasing environment risks and hazards. One critical consideration in establishing wind farms would the presence of constant strong winds, which is why many wind farms are located in elevated areas and even offshore locations are considered viable settings for this kind of renewable energy facility.

Renewable energy from water comes in many different forms. The most common would be the hydroelectric energy that is generated by waterfalls while some areas of the world also generate micro hydro systems that produce smaller amounts of electricity. Renewable energy is also tapped from currents deep under the ocean. This is termed as tidal stream power and several technologies have been developed to harness these viable source. Other sources of renewable energy generated from oceans would be tidal changes, temperature difference, tidal motions, and of course, waves.

Another viable renewable energy source is sunlight, which earth certainly has in abundance. There are numerous technologies developed to tap the solar energy and convert it into electricity, heating systems, and even cooling systems. Though most of these technologies are still in the initial stages, there is no denying the potential benefits promised by this renewable energy source. One of the leading concerns is cost of the materials used, though several affordable yet more efficient designs are still expected to be introduced into the market.

A lot of geothermal power plants had been built and have long been operational in several parts of the world. This is because this source of renewable source of energy generates power at low operating cost. Though some experts may contend that geothermal energy would not last as long as the others and is technically not renewable, it is still expected to provide large amount of power for a long time, even for a hundred years or so. However, it is still classified as a renewable energy source by the International Energy Agency and, like all other sources mentioned above, geothermal energy is reliable and environmentally friendly.

Though none of the renewable energy sources are considered to compete with fossil fuels just yet, it still provide some form of alternative for environmentally conscious individuals and communities in doing their share of lessening environmental degradation and destruction, something we can all ultimately derive benefits from.

Canada, making the most of hydroelectric power!

Known around the globe as a trailblazer in the utilization and development of renewable energy, Canada is near the top of the list in the use of hydroelectric power. Second only to China in hydroelectric power production, two-thirds of the electricity produced in Canada is derived from hydroelectric power. This statistic also places Canada in a relatively small group of countries which obtain the majority of their electricity using the power of water.

Because hydroelectric power production uses falling water to generate electricity, one does not have to stretch his imagination too far to think of Niagara Falls as a natural choice for the site of a hydroelectric plant. In fact, the world’s first such power station was built at Niagara Falls. To produce hydroelectricity, dams are built, often on rivers, and allow water to fall onto a spinning turbine inside the dam. As the turbine spins, it generates electricity. This type of renewable energy is nearly pollutant free due to its dependence on the naturally occurring forces of gravity and water. Only slight carbon emissions are given off by the motors in the dams that control gates and some pumps.

Applying falling water to the production of energy predates its application in producing electricity. According to The Canadian Encyclopedia, by the early 1870s up to twenty hydro-power machines were produced per day at just one Canadian factory. These machines were used in factories such as sawmills. As Thomas Edison began to produce electric generators in the 1880s using belt-driven turbines, Canada quickly developed the technology to adapt its hydropower plants into hydroelectric power plants. The country’s abundant rivers easily allowed it to emerge as a pioneer in the hydroelectricity industry.
Quebec in particular leads the charge of Canada’s sizable hydroelectric power industry.

Over 90% of Quebec’s electricity is generated with this renewable energy. Established in 1944, Hydro-Quebec is the world’s largest hydroelectric company. This government-owned utility is responsible for the distribution of electricity across Quebec. Hydro-Quebec maintains a network of 59 dams and one nuclear plant. Over 92% of the power supply sold by the firm is obtained from hydroelectric power. Quebec’s extensive river system is ideal for the placement of dams on waterways such as the Manicouagan, La Grande, and Saint-Maurice Rivers as well as Churchill Falls. The hydroelectric dam at Churchill Falls is the one of the largest in North America.

Though hydroelectric power plant development has slowed in Canada since the 1970s, they can still lay claim as a worldwide leader in the use and production of this renewable energy source.

Why Solar Power For Homes Is Becoming So Popular

Solar power for homes has developed something of an heroic standing within the green movement. Created by combining silicon with different elements that do have positive or negative charges, solar panels generate electrical energy noiselessly, and without detracting from a property\’s aesthetic. They don’t need to use a turbine in any respect, and they\’re easily built-in into the design of a structure, making them a easy addition to most current and new homes.

Solar power for homes is steadily becoming an increasingly more fashionable thing to do both in the US and elsewhere around the world, and for good reason. Solar power for homes is no longer just for the rich. The recent recession has brought about huge price reductions within the solar industry and government has opted to ofer a great deal of asssistance when people choose to introduce solar power for homes. So now, it\’s possible that most of us could afford to go solar.

Solar panels are devices that convert light into electricity. Solar panels convert photons of light into electrical current by a process often called the \”photovoltaic effect\”. Put more simplistically, solar panels convert visible sunlight into renewable electrical energy.

Solar panels are not be light so, when installing them, you must make certain that the roof is strong enough to take their weight, especially if the panel is positioned on top of existing tiles. Nevertheless, as soon as they\’re up there, solar panels get the best rate of return under the feed-in tariff, followed by wind turbines and then hydroelectric.

Photovoltaic solar panels have an average lifespan of more than fifteen years, but they are known to last a lot longer if well maintained. With tax rebates and lowered upkeep costs, you\’ll reap the financial benefits within months, if not years.

Solar panels for your home produce a clean renewable form of electricity with no carbon dioxied emissions into the environment. Although they were created in the course of the last century, large scale manufacturing only started recently. Photovoltaic panels are rather a lot less expensive and more highly effective now. Solar power for homes takes the most renewable energy source on the planet and converts it for use in our homes. No wonder then that t solar power for homes is becoming such a massive hit with so many people!

What is Alternative Energy

We need energy to do things in this world. In every aspect of our life, we find ways to harness it and use it in a constructive manner. But conventional sources are getting depleted fast, which leads to a need for renewable energy sources. There are quite a few promising sources that can be considered.

The term “alternative energy” can refer to any energy source that doesn’t burn any fuel or involve the splitting of atoms. Because of the pollution caused by our standard energy supplies, there’s a growing interest in finding good alternative energy sources. Hopefully, this doesn’t stop at wishful thinking.

Renewable energy sources, such as solar power, geothermal energy, wind power, tidal power, and hydroelectric power, are being seen as possible future replacements for conventional and less clean energy sources. Technology is still being researched and developed, to fully maximize their efficiency.

Solar Power

Among the alternative energy sources in use today, solar energy is possibly the most well known, especially in places where the sun is always shining. The Earth receives a considerably amount of solar energy on a daily basis, but only a small percentage of it is put to good use. It is used to power heating systems for homes and businesses, to run cars, and to operate space satellites. And as research advances, the future looks bright for solar energy.

Geothermal Energy

Geothermal Energy is produced by the internal heat of the Earth, which could be used to generate steam to run a steam turbine. The turbine would then generate electricity. It could provide supplementary power even if not functioning as the primary source.

Wind Power

Wind power is one of the cleanest forms of energy production, able to generate electricity without harmful byproducts. The disadvantage is that its use greatly depends on the weather conditions in a particular area.

Hydroelectric Energy

Tidal and hydroelectric power share the same basic principles in how they generate electricity. They utilize the force of the water’s movement, and convert it into electric power. In hydroelectric plants, water is usually stored behind dams. As soon as the water has been released at a high pressure, it is used to turn the turbine blades below, which are then used to generate electricity.

As technology advances, we become increasingly more capable of harnessing the full potential of our clean and renewable energy sources. It is vital that we continue this research and development, and eventually put an end to the use of fossil fuels or other polluting elements, with their harmful effects on the environment.
