One gets to hear about green energy a lot these days. This is because of various reasons. Firstly the environmental impact of burning fossil fuels is immense, most notable consequences being global warming and the depletion of ozone layer. As we continue to emit green house gases, there is a thrust on developing green energy, which is energy that is clean and hence doesn’t pollute the environment. Also green energy is something that doesn’t take away anything from our existing environment and is therefore renewable.
What makes green energy so beneficial is the supply of power without using up any of the planet’s resources. So while petroleum and coal cannot really be replenished, green energy obtained from wind farms for example, can be produced continuously, once the initial setup including the grid is established. Moreover, wind power or solar power, are classic examples of green energy that can be harnessed to eternity without really causing any harm to the planet.
Another important aspect of green energy is its ability to clean up the existing environment. Biomass is a very popular green energy source which uses up industrial, plant and animal waste to generate energy. This green is used in rural areas for electricity as well as agricultural purposes. It must be understood that green energy is not necessarily producing energy from clean resources. Green energy could also refer to scenarios where efficient construction or mechanisms can help save energy.
A good example of green energy mechanisms is offered by many modern buildings which are designed to harness solar energy that can be utilized for interior lighting and power needs. Moreover, the design of the building ensures that the heating needs at night are taken care of by the green energy stored during the day. Similarly, the design ensures that the cooling costs during the day are also lowered to a great extent. Double glazed windows provide a great example of how green energy scenarios can benefit us every day. Such windows reduce our cooling costs during summer and our heating costs during winter. Thus green energy mechanism also help cutting energy costs along with saving energy.
