Alternative Energy Sources

There are many sources of alternative energy on earth, and these include geothermal energy, wave power, wind power and solar energy. These alternative energy sources are environmentally friendly and also help reduce the carbon foot print that is being left by man due to the consumption of fossil fuels. Alternative means of energy generation are usually attained from a renewable source, which means that the source seems never ending and does not deplete the earth of its natural resources. Out of all the alternative means of energy generation, solar energy is the one that is the most easy to harvest and utilize. Geothermal energy, wind power and wave power require specialized equipment in order to harness them. Solar energy on the other hand simply requires PV panels which are very easy to install and even easier to maintain. Wind power and wave power have been used to generate power for years, but they do require some utilization of fossil fuels, which doesn’t help the environment at all. Solar energy, tidal power, wave energy, geo thermal energy, wind turbines and wind mills all are forms of alternate energy that can produce electricity.

Solar energy utilized since the ancient times:

Solar energy has actually been harvested since the ancient days by prosperous civilizations, who understood the real potential of the sun. They used solar energy for many purposes. The light and heat of the sun was considered a source of tremendous power, and many methods were utilized by the ancient civilizations to harvest solar energy. The Romans, Greek, Egyptians and the Mayans were known to build buildings in such a way that they could actually utilize the sun’s rays in the most maximum way possible in order to light up their homes. They were able to create sun clocks, and also utilized solar energy for heating water. They also used the rays of the sun to cook and preserve food like chilies and dried meat and fish.

Solar energy: the ideal alternative energy source:

Solar energy is a form of alternative and renewable energy that is the most cost effective and easily attainable of them all. Other forms of renewable energy are geo thermal energy, wave power and wind turbines, but they require expensive material and difficult to maintain equipment in order to generate electricity. In order to harvest solar energy, PV or photo voltaic panels are required. These panels consist of photo electric cells that create current electricity upon exposure to the sun’s rays, due to the photo voltaic effect. The PV panels consist of solar cells that are composed of photo voltaic material, which is able to create electric current from solar energy and supply us with electricity. PV panels can actually be set up on any appliance big or small. They can be set up on an appliance as small as a calculator and they can also be set up on a huge scale such as in industries.

Solar Energy Advantages:

Not only is solar energy one of the best forms of alternative energy but it also has many advantages over other sources of alternative energy like wind mills and wave power. Mentioned here are a few of them:

It is free of cost: Solar energy is attained from the sun, and it does not cost anything to harness the sun’s rays. It is absolutely free, making it one of the cheapest forms of renewable energy on our planet.

Its source seems never ending: the sun has been in the sky since the dawn of mankind, and it seems to be a never ending source of power. Even on cloudy days, solar energy can be saved in the solar cells and be utilized at night time to power up appliances for several hours.

Solar energy is emission free: solar energy does not deplete the earth of any of its natural resources and is absolutely emission free.  It does not consume fossil fuels nor has any hazardous effects on the environment. It is environmentally friendly and a “green” source of electricity generation.

Equipment is easy to install: all you need to harvest solar energy is PV or Photo voltaic panels. These are very easy to install and require practically no maintenance.  In order to harness wind power or wave power expensive equipment needs to be set up and specialist knowledge is required in order to maintain it. PV panels on the other hand can be built of any size. They can be tiny enough to be fitted on top of street or park lights, and they can also be made on a gigantic scale, to be used in industries.

Solar energy can be used in many ways: solar energy can be used to create electricity for lighting, sterilization, distillation, space heating and space cooling. It can also be used for water purification, for water distillation and heating of swimming pools. Solar energy can be used to cook food, power homes and even cars. It can be reflected, stored, converted into other forms of energy, deflected and also harvested. It can actually act as a secondary source of power for homes and even factories and one can save tremendous amounts of money on electricity bills each month with the help of solar energy.
