What is Green Energy?  Would you like to discover your way to helping the environment and making your home better and sustainable?  Here is an overview of green energy.

Global warming is among the greatest world concerns today. It has prompted for various programs to be launched by organizations both from the private and government sectors. Among these initiatives is the development of green energy.

Green energy pertains to the power generated from natural sources. The most popular types of green energy come from the sun, wind and water. These are called ‘green’ mainly because these sources are initially free from any sort of pollutant.

They are better alternative energy than power generated from fossil fuels such as coal, which are known to produce adverse effects to the environment. These traditional power plants are often associated with carbon dioxide emissions, which could totally upset the ecological balance. These also cause the atmosphere to get thinner, which ‘opens’ up the earth to the harmful rays of the sun.

Energy from nuclear sources is sometimes referred to as green energy options. While this type of energy is not initially known as eco friendly, there are now developments for it which make it suitable for earth friendly power production. It is regarded as such because nuclear energy has lower waste output that coal or oil-fed power plants.

The solar energy is typically harnessed through the use of photovoltaic solar panels. These come in different sizes, depending as to which establishment or building they would be installed in. Some solar panel options are available in ready-made form, while there are some do-it-yourself solar panels.


Solar energy generated from the solar panels or solar cells through the solar power photovoltaic (PV) system directly converted to electricity. The electricity generated supplies the household usage thus reducing the electricity bills.  The solar renewable energy are used for lighting, cooking, water heating, most household appliances and can even powering vehicles.

In certain part of the world, they are already using solar power for traffic signs where the power can’t reach them.  It is a cheaper way of making use of the natural sun and cut down the burning of the fossil fuels to produce the electricity.

As for the wind and water sources, they are usually made capable of producing energy through the installation of turbines. These are typically composed of blades, a rotor and a generator. The rotor is attached to a tall tower typically of about 20 meter high. The taller the tower is better as winds are stronger at higher level from the ground.  These too come in variety of sizes and availability – whether “off the rack” or DIY green project.

Wind turbines are best installed in an open space where there are lots of wind and not many tall buildings because they depend on wind to produce the electricity.  They are generally more suitable for the locations such as farms, in the country area with plenty of space or on the coast.  Initial cost may be expensive but you will save money in the long run and also they are being environmentally sustainable.

For all the green energy generators, they are now available in large versions. There are now companies here in the US, UK, Australia and other parts of the world that utilize these alternative renewable energy sources to supply electricity to an entire community power grid.

On the other hand, there are also different approaches as to what is green energy?  Some environment advocates claim that a green energy source is not delimited to the above mentioned alternative power sources.

For one, architectural structures built with eco friendly measures are considered sources of green energy too. Say, a building that is made with sustainable materials or is designed with efficient ventilation, heating and cooling mechanisms will be a potential green energy source. The energy efficient appliances such as refrigerators, washing machines, dish washers that consume less energy fall into this category as well. These are regarded as such because their operation would not necessitate tons of electricity to be fully functional. In a way, they are contributory factors for the betterment of the environment.

Growing vegetables in greenhouses in our backyard can be fun as well as better for our health without all the chemical additives and they are tastier.  Solar energy produced in the greenhouses are used in winter seasons for certain type kind of vegetables such as broccoli, cauliflower and cabbage. In large vegetable farming processing plants, they use solar energy produced by solar panels for vegetable processing and freezing operations.

Through this simple ‘What is Green Energy’ guide, you can then contemplate whether any of these alternative energy sources would be suitable for your electricity needs. Just think that with these, you get to save the environment and enjoy reduced bills as these sources are free eternally.
