It is very important that we consider renewable energy as the energy source of the future. The price of fossil fuels will become dearer and its availability will become scarcer. This is for certain. Fossil fuels are finite resources and they will not last forever. Therefore, we need to research and invest in a solution that will last the test of time. This solution must be kind to the environment too or we won’t even have a home to live in. Fossil fuels leave large amounts of CO2 in the atmosphere after burning and this lead to climate change. The sooner we cut our dependency to fossil fuels in favour of renewable sources the better it will be for us and our planet.
The need for effective, environmentally friendly and sustainable energy resources is fundamental to the preservation of the environment. Thereby energy resources must be renewable. They must be accessible, effective and self-replenishing.
Much time, effort and money has been ploughed into the renewable energy industry in the search for solutions. Huge grants are available to scientists all around the globe. When we think of renewable energy vs fossil fuels we think of the new vs the old. Renewable energy conjurs up images of cutting edge technology and innovation. This contrasts highly with the fact that renewable energy is as old a phenomenon as the Earth itself. Yes, the technologies used to harness the sun and winds energy are scientifically very advanced, but using these as energy sources is by no means a new discovery. People have been using renewable energy for many years.
In the days of the first humans on earth, the humans would obtain energy through the food that they eat. As the early human evolved they learned how to develop tools and implements. These tools allowed them to further exploit energy to overcome their physical limitations. Further down the evolutionary timeline, humans developed an agrarian society where agrarian energy was harnessed and this led to the human race flourishing. The first sign of wind power being harnessed was seen in 3000BC. The Egyptians created the first sail, which harnessed the power of the wind. This aided transport and a new ‘Age of Discovery’ was born.
The invention of the windmill in the first century marked a further development in wind power, with the windwheel of the Greek engineer Heron of Alexandria one of the first known instances of wind powering a machine in history. By 1000 AD windmills were used extensively across the Middle East, and spread quickly to Europe. Today, wind power is one of the world’s fastest growing energy resources using non-emission wind turbines to make electricity.
