Alternative Energy Sources: Solar Energy

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 footprint 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 easiest to harvest and utilize.

Geothermal energy, wind power, and wave power require specialized equipment 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 electricity 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, geothermal energy, wind turbines, and windmills all are forms of alternate energy that can produce electricity.

Solar energy is utilized since ancient times:

Solar energy has 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 were considered a source of tremendous power, and many methods were utilized by the ancient civilizations to harvest solar energy.

Alternative Energy Sources: Solar Energy

The Romans, Greek, Egyptians, and the Mayans were known to build buildings in such a way that they could utilize the sun’s rays in the most maximum way possible 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 geothermal energy, wave power, and wind turbines, but they require expensive material and difficult to maintain equipment to generate electricity.

To harvest solar energy, PV or photovoltaic panels are required. These panels consist of photoelectric cells that create current electricity upon exposure to the sun’s rays, due to the photovoltaic effect.

The PV panels consist of solar cells that are composed of photovoltaic material, which can create electric current from solar energy and supply us with electricity. PV panels can be set up on any appliance, big or small. They can be set up on an appliance as little 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 windmills 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 free, making it one of the cheapest forms of renewable energy on our planet.

Unlimited energy

The sun has been in the sky since the dawn of humanity, 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 does not deplete the earth of any of its natural resources and is 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 Photovoltaic panels. These are very easy to install and require practically no maintenance. To harness wind power or wave expensive power equipment needs to be set up, and specialist knowledge is required 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 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.
