Various Renewable Energy Resources And The Best To Use At Home

So do you want to know about renewable energy?

I understand why a lot of people are interested in this subject. In fact, I am one of them myself.

Renewable energy is becoming a very important resource of power; even governments are conducting huge researches on this matter.

I want you to think about this for a second- What if all countries and individuals use renewable power, how would it be?

Well, it will definitely change the future of the planet.

Renewable energy

It is the energy generated from natural resources such as sunlight, wind, geothermal heat, and many other resources. These resources are naturally replenished.

Geothermal energy: It is obtained by trapping the heat of the earth itself. It can be done in some places from the surface and in others it has to be a few kilometers deep.

Hydropower: Energy in water can be harnessed and used. Water is about 800 times denser than air, so even a slow flowing stream or a moderate sea swell can yield a considerable amount of energy.

Bio fuel: There are various types of bio fuels that could be made out vegetable oils, animal fats, the sugar components of some plants and many other resources.

Solar energy: It is the energy derived from the sun through the form of solar radiation.

Wind energy: Air flows are used to produce energy.

Warning: These last two renewable energy resources are perfect for everyone to use at home or even at the office. You can easily buy or build your own solar panel and wind turbine, and produce green free energy.

You can go green and start using renewable energy resources!

Present-Day And Future Alternative Energy Sources

The major past energy sources have included petroleum and coal. With the sharp increase in energy prices, depleting non-renewable sources of energy, the increase of green house gases impacting global warming, the future of using alternative 'green' sources of energy looks bright. Governments around the world are feeling the pressure of consumer demands for alternative renewable energy sources that will not harm the environment.

Wind Power is one method of producing 'green energy' that is becoming popular all over the world. Wind turbines are used to create power. Wind turbines can be placed wherever there is sufficient amount of wind. The higher the number of installed wind turbines, the more electricity will be produced.

Solar energy is one alternative energy source that is expected to see an increase in use in the future. This form of energy makes use of the sun for power and heat. Solar panels harness the power of the sun without polluting the planet and atmosphere. The solar panels power generators provide the electricity. The solar panels are installed on the roofs of residential and commercial buildings. In the future, larger solar panels will be built that can power hundreds of thousands of homes Solar energy requires does not require any other energy source to operate and it is free of pollution. Sunlight can be harnessed as usable heat or converted into electricity using photoelectric cells, solar panels, or using synchronized mirrors called heliostats that follow the sun as it moves. Methods for using solar power to replace a gas-powered engine by heating hydrogen gas in a tank have also been developed. There have been positive results with powering a generator.

Hydro Power is another alternative energy source with proven results. The flowing water drives the turbines which produces the energy. The energy created is dependent on the strength and force of the water flow because rapid flowing water drives the mechanisms that help with producing electricity. The current is then sent through a transformer where the electricity is transmitted over power lines. This is an eco-friendly form of energy and in the future, it is expected that more hydro power stations will be erected where there is a suitable water supply.

Current technologies for new renewable green energy sources, particularly solar power and wind power, are proving to be quite promising for the future. As well, Geothermal Energy which is heat energy extracted from the earth to create steam to power the generators that produces the electricity, is another potential future large energy source. There is also much research and development going into Nuclear Fission. Salinization of water at river estuaries as an energy supply is another possible source of alternative energy because many experts suggest that it will be millions of years before there is any impact. Nuclear fusion and artificial photosynthesis are two other energy technologies currently being researched as possible future energy sources.

Much of the traditional sources of energy are becoming unsustainable making new greener sources of energy the wave of the future. Many corporations, 'green' entrepreneurs, and governments are investing in the future of the planet and its inhabitants by investing in alternative renewable energy sources. An investment in 'green' energy means a future of low energy costs and a greener sustainable environment.

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. 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 steam plant.

Hydropower Renewable Energy - Fossil Fuel Replacement

Approximately ten percent of energy produced in the United States is from hydropower. In this process, water spins in turbines in generators.

Hydropower is one of the renewable energy sources being researched and implemented to replace fossil fuels, which are in the process of depletion. It does not produce carbon dioxide, as coal power stations do, making it a cleaner, as well as, cheaper alternate way to produce electricity. It is also renewable, with the help of rainwater for replenishment.

The impoundment facility is the most common type of hydropower facilities. A dam is built on a large river or lake to store its water in a reservoir. When water is released from the reservoir through tunnels it flows through a turbine. Since the height of the water behind the walls is so great, the released water goes through the turbine with a great force of energy. As the turbine spins, it sets in motion a generator, which in turn produces electricity. The water then travels back into the stream or river below. Networks of transmission lines and facilities carry the electricity from the generator to users in a form they can use. The Hoover Dam is an illustration of the process just described. When it was initially built, it produced enough electricity for the entire city of Las Vegas. As Las Vegas grew, they turned to other energy sources

The pumped storage hydro plant facility is able to store power. It does so by pumping water from a lower reservoir to an upper reservoir during low energy demand periods. When needs increase, the water is released from the upper reservoir back to the lower reservoir for electricity generation.

Hydroelectric plants require a lot of land in order to build a dam and reservoir. This requires a great deal of money, time and construction. There are not many ideal places to put them and most of these have already been taken. The good thing is once constructed; the electricity is free to produce. Due to costs, the tendency will be to put up smaller hydro plants that are more economical.

Hydroelectric plants using dams have a negative effect on the environment. Through the construction of a dam, there is a blockage of the flow from upstream to downstream. This disrupts the migration pattern of fish. Fish can also be killed passing through the turbines. An advantage to hydropower is the ability to control energy release to meet changing demands.

The population is growing and so will its power needs. Fossil fuels are being used up and there will come a time when they will be depleted. We need to turn to renewable energy sources to meet our needs. Natural resources seem to be a natural solution. Hydroelectric plants can meet our power needs without worries of depletion or pollution. It is also the most reliable source available today. Research and development is ongoing to provide a solution to the damage a dam can do. The potential for hydroelectricity is within our grasp and we must find a way to make this work.
