The need for alternative energy sources is nothing new but in this present time, the need is urgent on a global level. People and governments are reeling from the impact of the startling rise in energy costs and alarmed at the many dangers posed by environmental problems.

Across history, we have seen change in the kinds of energies used. As early as the 1200s, people swapped wood for coal as deforestation occurred locally. 300 years later, societies then depended on petroleum after depleting the supply of whale oil used to fuel lamps. In the early 1900s, corn-based ethanol oil supplied the demand for energy.

When the world started to run on wheels and navigate the skies and seas, the need for fuel increased, eventually drying up local oil wells. As a result, the US turned to importing oil to keep transportation, industry, and domestic needs moving, eventually relying so heavily on foreign oil that 58% of its supply is now imported.

According to the latest statistics from the US government, global energy consumption is still increasing and by 2030, it’s expected that the world will require 700 quadrillion BTU in order to keep running.

Switch or Stay?

Besides the depletion of our natural energy resources, across the globe, people are also feeling the effects of the increasing cost of electricity and the rising cost of living expenses. On the home front, this poses a dilemma, as family needs are a priority, and electricity certainly qualifies as a basic need.

So what are the alternatives to providing the basics, yet still offer affordability?

As a result, many people are seeing “green”. The green movement is tapping alternative energy sources instead of relying too much on utility companies for energy needs. Alternative sources of energy provide renewable sources for your electricity needs at the fraction of the cost of utility-supplied energy.

The switch to alternative sources of energy will take time to put into action across the country but as the energy landscape changes, more homes and industries will be using alternative energy. likely triggering the decline of over-dependence on imported oil. This will be good for economies dependent on expensive imported oil, like the United States.

These are very good reasons for evaluating alternative energy sources NOW.

To get started, assess which alternative source of energy is best for your needs – solar, geothermal or wind energy options.

Popular Forms of Alternative Energy Sources

Solar energy is a favorite renewable energy alternative for domestic energy. This option uses photovoltaic technology to convert sunlight into electrical energy. Solar panels alone produce hot water and steam. Combined, these technologies provide optimum energy to power homes. Solar energy has very low levels of carbon dioxide emissions compared to gasoline emissions of the same chemical compound that is partly to blame for climate change.

For geothermal energy, the earth’s heat is tapped to supply energy needs. To trap this energy, holes are drilled deep to the level where a potential geothermal heat spot is present. The escaping steam is directed into a turbine linked to a running generator, which converts steam to electricity. This is the preferred method for large industry and utility companies.

The homeowner, however, need not dig so far to enjoy the benefits of geothermal energy. The geothermal heat pump uses the stable ground temperature a few hundred feet under the ground to provide you with heat and air conditioning. It can also provide you with hot water.

Wind energy is converted to electricity with the use of wind turbines. Wind power produces a minimal 1.5 per cent of the world’s electricity. Currently, this is a popular alternative energy source in Denmark, Germany, Spain and Portugal.

Choosing Your Alternative Energy Source

Keep in mind that it is not cheap to install solar panels or invest in geothermal or wind energy – it will depend too on the volume of electricity you need to power your home – but the rewards later on will last a lifetime. You may also be eligible for a federal tax credit, if you’re a US resident, but many governments around the world are offering incentives to residents to convert to renewable energy sources.

Talk to alternative energy merchants and ask them to help you make the transition from utility supplied energy to alternative energy source today.

Alternative energy is a general term used for all sources of usable energy that can replace the fuel sources. Toqualify as the source of alternative energy, it should not have undesired consequences of the fuels it replaces.Nuclear energy and fossil fuels cannot be called alternative energy sources as they have high levels of carbondioxide emission and contribute to the global warming.

Many countries have signed the Kyoto Treaty that calls for efforts to reduce the greenhouse gases andpollutants. Use of alternative energy helps preserve many natural resources that are currently being used togenerate power.

Various Sources Of Alternative Energy

There are many ecologically friendly alternatives energy sources that can replace the fossil fuel. These sourceshave less impact on the environment, and at the same time, do not consume huge amounts of natural resources.

Alternative energy can be drawn from many untraditional sources such as compressed natural gases, winds, sun andhydropower.

Alternative energy can be drawn from many untraditional sources such as compressed natural gases, winds, sun andhydropower.

We have made use of solar energy for many years, and today, we know various ways in which it can be usedefficiently. Solar energy can be categorized as heat or thermal energy and light energy. Solar thermal technologiesheat the substances by using solar hear energy, and this energy is applied in water heating, pool heating or spaceheating. This alternative energy is renewable, and releases no air or water pollutants. This energy can be veryefficiently used for lighting and heating.

Wind power is another alternative energy and it harnesses wind power to propel blades of wind turbines. Theblades of turbine rotate, and convert the energy into electrical current with the help of electrical generator.Wind power does not cause any pollution that may contaminate the environment. As there are no chemical processesinvolved, there is no left-over of harmful products.

Another source of alternative energy is geothermal energy, which means the earth heat. Geothermal energyinvolves harnessing the heat energy that is present under the Earth. In Earth’s crust, there are hot rocks thatheat the water and produce steam. When holes are drilled in these regions, the purified steam shoots up and is usedto drive the turbines that power the electric generators. If done carefully, this alternative energy has no harmfulby-products.

Hydroelectric energy is another alternative energy that comes from the energy of dammed water driving generatorand water turbine. It is also possible to use the undammed sources and kinetic energy of water. Hydropowerharnesses powerful gravitational descent of the water compressed from a long run with a flume or dam. Thisconcentrated pressure created by flow of water can be used to turn the water wheels or turbines.

And this is where alternative energy sources play a vital role – in preserving the earth’s ecological balance by generating energy that doesn’t use fossil fuels, thereby conserving these non-renewable resources. This in turn significantly reduces the toxic byproducts released by fossil fuels during the energy generation process.

Putting it simply, alternative-energy is energy derived from sources other than the conventional fossil fuel sources of oil, natural gas and coal. When we say fossil fuels are nonrenewable it means that they’re limited and will gradually run out, making the process of accessing them expensive and hazardous to the environment.

The way out is to tap into the earth’s renewable resources that get replenished and won’t run out such as solar and wind energy.

Plenty To Replenish!

Though one thing’s for sure – alternative energy is an environmentally sound replacement for fossil fuels that emit carbon dioxide, contributing to global warming. Global warming is another green term we often hear or read in the media. But what exactly does it mean? Global warming is basically a process which leads to an increase in air temperature due to heat trapped by greenhouse gases like methane, carbon dioxide, nitrous oxide, CFCs and ozone. These greenhouses gases are a result of human activities…

Eco Cool

As you can imagine, producing oil, coal and natural gas is a complicated physical and chemical process that have a negative impact on the environment. Whereas, alternative energy is easy to produce and requires simple equipment and processes.

There are plenty of ecologically friendly alternatives – solar, wind, tidal, geothermal and hydro power, biofuel and biomass. As compared to fossil fuels, their environmental impact and polluting properties are much less since they largely get their energy from the sun.

Go Green 

Alternative energy is a practical option to nonrenewable resources and an urgent need. If we want to repair and undo some of the environmental damage we have wrecked on our planet, our future needs to look green. And it has to start now, with our governments and ourselves… A good starting point is to switch to homemade solar and wind power systems.

Solar Energy:

We are aware that sun is the source of all energies excepting nuclear energy. In fact from fossil fuel whatever energy sources we receive on this earth, solar energy is stored in them. All over the world today different researches are in process as to how this most non-polluting and huge source of renewable energy can be used in an optimum way. We are able to derive this energy by the use of photo electric cell.

Geo Thermal Energy:

Geo thermal energy utilizes the heat energy that is produced within earth. The energy received on the earth by hot water springs and geysers. Many countries are making its best use for different purpose. There is a good possibility to produce electricity from geo-thermal energy with a very less pollution.

Nuclear Energy

It is a tremendous potential source of energy on the earth. A mature energy source but generates dangerous pollution and toxic effect on the earth. Different researches are continuing if the source can be utilized with correct solution.

It is highly expected that the harmless, eco-friendly and enormous sources of renewable energies will help us a lot to meet the future energy crisis.
