Everybody in this world is aware of the fact that three of the most basic renewable energy sources are wind, water and sunlight as they are naturally abundant and most importantly, they are found free throughout the planet. Irrespective of this abundance, we are still not utilizing them in the best possible way.
We use energy everyday and energy has become one of the most important necessities of our modern daily life. We still use fossil fuels as our main energy source but, as most of us realise, our world has limited fossil fuels remaining. In the near future the day will come when our world will run out of fossil fuels which took years to create within our earth’s crust.
Fossil fuel as a main energy source is also not good for our world and our health. The carbon emissions from the burning of fossil fuels are gradually polluting our planet and ultimately causing global warming. We are polluting the air we breathe which poses a great threat to mankind. So is there a way-out of this problem? Yes, if we can deploy a method to harness alternative energy sources like wind, sunlight etc. and start using them in our daily life so that we can eradicate pollution producing fossil fuels from our everday lives!
Using renewable energy sources is not new and people have been using those resources for many years. But the scale required to solve our planet’s problems is a major hurdle to their implementation. The challenge is to devise a new way to make efficient use of our clean energy resources. If we want to see them implemented in industry we need to meet several challenges. They must be economical to produce, economical to implements and match of increase overall operating profits for the company.
Energy from the wind can be used for the production of electricity which is collected through large wind turbines. This allows smaller setups and electricity being available even in remote places where the normal distribution networks may not have yet reached. Using such a powerful and readily available energy source could mean much prosperity and growth to small and remote communities as well as larger cities and industrial sites.
Hydro-electricity which is literally electricity from water is one of the most reliable forms of renewable energy currently available. Energy can be obtained directly from the riverbed without causing any greenhouse effects or global warming. Water electricity is currently being produced at a variety of dams around the world. The only real pollution is in the initial setup of the infrastructure and the transportation or distribution of the resultant power.
Solar energy is another form of energy which is cheap and can be easily used anywhere around the world without much setup cost. Its obvious limitation is of course that it can only be used during daylight and when the sky is free from clouds.
The Two most important factors when considering renewable energy sources are their sustainability and their scalability. Renewable energy sources are considered sustainable if they are naturally abundant and renewable. Scalability looks at whether they can be setup anywhere around the world and whether their resultant power can easily or sustainable distributed to end users. The hurdles that have made renewable energy sources a poor option are quickly being addressed and overcome as the world enters the final stages of its fossil fuel dependence.
