Common Misconceptions About Alternative Energy Sources

Alternative and renewable sources of energy are just now getting to a point where we can actually begin to reap their benefits and are becoming more and more accessible to the general public. Because if this, it's becoming far more important for us to understand the differences between myths and facts when it comes to these different types of energy resources. I's really important to try and clear up any confusion there may be about them and what they are capable of and what their limitations might be at this time.

Below is a list of some of the different types of renewable resources and what they are and what they are used for:

Wind - This is energy that uses large windmills or wind turbines to gather up the streams of wind that will then turn the blades that will then operate generators that will produce our electricity.
Solar - Solar panels can work in a couple of different ways. Some are made to use the light of the sun and change it into an electric current through chemical reactions. The other will focus in on the heat energy of the sun which can heat water and then creates a steam that can be used to activate turbines that will produce electricity.
Hydroelectric - This is a power source that uses the power of waves or watering rushing in that will create electricity.
Biodiesel - Is the newest of them all and this is a source that uses organic biomass, such a corn or other plants to make chemical reactions that will produce a usable fuel for cars or for heating our homes.

One of the more common misconceptions or misunderstandings about the different alternative fuels is that many think that they will provide an immediate and complete replacement for the fossil fuel based energy that is still the major source of energy that we use. Unfortunately since the renewable energy is still in it's infancy, there is still a long way to go with regards to the research and development of systems that will produce efficient energy and enough of it to make it feasible to replace our fossil fuel systems.

Another misunderstanding is that people think that the cost of the alternative sources will not be that bad and the benefits will be far better. Remember, these sources are still in their infancy as compared to fossil fuels and that means that it will take a lot more money in the beginning to be able to find ways to maximize the efficiency of these renewable resources.

So this means that the cost to you and me will be probably no different than what we are paying now. It definitely will not be less, not for years to come. The best thing that would come from them at this stage of the game is that the footprint left behind by these resources will be immediately much less than that of the our current source of fuel.

No matter had bad that we want to believe that there is an energy source out there that is totally clean, there isn't. That is one of the biggest myths you find attached to alternative sources of energy that they are perfectly clean and that is simply not the truth. Although these resources are being designed to produce energy with the least amount of impact on our environment, the places that will provide this energy will still require resources to help build and maintain the facilities.

Also many forms of the renewable resources will not go on forever either. Such as water, with the continued growth of world populations, water will become a scare commodity and could once again start a new set of problems for energy throughout the world. Things like this need to be considered when switching to different sources of fuel and energy.

Although the different alternative energies cannot at this time completely replace fossil fuels they can however begin to lessen our dependence on them. Also, with all of the different possibilities on the horizon, an entire new industry will be created which in turn will create a need for new jobs and people to fill those jobs. So by beginning to turn our attention to the newer types of energy we can not only help to start cleaning up the environment but we will also be able to help a lot of the local economies along with the national economy gain in strength with more jobs.

About Wind Energy - Its Pros and Cons

There are many who think that the concept of wind energy is relatively new. However, this is not the case. About five thousand years ago, the Egyptians were already using the sails in their ships to channel the wind and make their sea vessels faster and efficient. Also, somewhere between 500 to 900 A.D. Persia had already designed and developed the grain-grinding and water-pumping systems. The mechanism of these machines was supported by the wind energy.

The world as a whole realized the critical issue of depletion of the resources, when it first faced problems due to the shortage of oil in the previous century. Since then, engineers and researchers are trying to craft solutions to make the best use of the renewable energy resources. Wind, too is being used as a source to produce energy that can be used in place of oil. There are several benefits of using wind energy, which include;

1. Minimal or zero pollution

Wind itself is a natural and healthy power source, which can be converted to energy with the help of the machines called 'turbines'. However, this conversion does not involve burning or combustion of any sort. Thus, wind energy features a green and pollution-free alternative to oil.

2. Cost efficiency

Since the wind itself is a renewable resource, it is not inclined to get exhausted or be used up entirely. This makes wind energy a cheaper option than the other renewable energy sources.

The machine used for the generation of energy is referred to as the 'turbine'. The turbines are of two types; the horizontal-axis turbines and the vertical-axis turbines.The horizontal-axis turbines however, are more commonly used and they can be as tall as a twenty story building. The top three energy generating states in the United States of America are; California, Iowa and Minnesota. The generation of wind energy by California is more than twice the energy generation of any other state.

Despite the many benefits, there are certain disadvantages as well, which are associated with the generation of wind energy.

1. Beauty and noise pollution

The wind turbines need to be installed in the open areas. The regions where the economies benefit from tourism, will be adversely affected with the installation of the wind turbines.Moreover, there are others who have shown concern about the noisy of the turbines as well.

2. Effect on wild birds

According to the studies conducted by the wildlife researchers, using wind to generate energy is likely to harm the wild birds and their visual impact on land and sea.

About Solar Energy

It was Da Vinci who predicted the solar industrialization in 1447. Today, we are looking forth to generate solar energy, acknowledging it as one of the most effective ways to transform the sun rays into energy. The process through which sunrays are transformed into electricity is referred to as the PV or the Photovoltaic technology. The solar energy is considered as a green alternative to energy, which has minimal carbon footprint.The various equipment used for transforming the sunlight into energy include; solar panels, thermal collectors and generators. Unlike the other sources of energy, the energy generation does not involve combustion and thus, it does not produce dangerous fumes. The energy can be used for two purposes;

1. To provide heating

2. To provide electricity

The solar panels are used to convert the sun rays into electricity; however, the solar thermal collectors allow the sun rays to convert into heat energy. These thermal collectors can also be installed in homes and other buildings, to work as efficient heating systems in the chilling weather. The unit for measuring the solar energy is kWh or kilowatt-hour. One kWh can also be described as 'the amount of electricity required to burn a hundred watt light bulb for ten hours'. It makes sense to utilize sunlight that the earth receives as; in one hour our planet receives more sunlight than the consumption of energy by the entire world's population in one year. Making use of this renewable form of energy, the world can not only meet its energy requirements, but also, provide electricity to a population of two billion people who are currently living without electricity.

There are many advantages of using the energy. Those who make use of the solar-energy systems to assist with their electricity needs will witness a reduction in their electricity bills. Moreover they do not have to worry about the increasing rates of gasoline or other forms of energy. The green consumers will not have to worry about the carbon footprint. The energy helps in decreasing the adverse effects of greenhouse gas emission. In almost all the cases, the solar energy systems are virtually maintenance free. Also the efficiency of these systems can be increased as the energy needs of a household or an office increases by adding more solar panels. There are also certain disadvantages associated with the consumption of solar energy, which include;

1. The high initial installation cost

2. Dependence of system efficiency on the location of the sun

3. Large space requirement

4. No energy generation in the night.
