Evolution of Energy Sources

Today’s world runs on energy. Life does not seem to exist without energy. While this might seem obvious, it has been a dramatic evolution in terms of history. Prior to industrialization, humans utilized minimal energy beyond what the basic natural resources such as water, fire, wind, and what human labor could provide. The saying “you cannot produce more power than you consume” was a school of thought championed by the scientific community – and it became some sort of mainstay in the minds of people. However, tracing the innovations that led to modern energy has not always been straightforward.

Trying to understand how the artistic and technical works in ancient Egypt was achieved in the darkest basements of the pyramids has led to surprise and curiosity.  But how did they manage this feat? The walls covered by reliefs in crypt in the Hathor temple at Dandera of Egypt have attracted the interest of theorists who believe that the Egyptian priesthood, first harnessed the hidden potential of electricity. Yes, electricity predates Benjamin Franklin and Thomas Edison, having its origin in Ancient Egypt.

One of the relieves found in the crypt ignited the interest of a Norwegian engineer, and he was certain he saw a depiction of an ancient light bulb in the wall of the temple of Dandera of Egypt. This revelation also caught the attention of researchers and other engineers, and after studies were carried out, they agreed that the wall depictions on the relief in the temple represented an electric light bulb.

With the advancement of industrial revolution, attention drifted away from renewable energy sources and this need was compounded by the desire for high-density sources of energy for transportation. Attention now turned to the immense natural energy sources such as sun, wind, and even water. While there was never a doubt about the potential any of these sources promised, the challenge remained harnessing them successfully to meet up with demand.

The challenge has well and truly been overcome over time, and with the development of wind turbines, solar photovoltaic technology, and nuclear energy, there are huge prospects and confidence that the energy in nature can be successfully harnessed. Solar technology in particular has great potential in solar climates, and their costs in the long run are pocket-friendly when compared to the value they offer over time.

However, there is still room for improvement. While it is pretty easy to assume that science has reached its peak, history has proven that the saying “you cannot produce more power than you consume” cannot be true in any way. In fact, water has never been as important as it is today in generating electricity. In the US alone, hydroelectric energy source generates about 10 percent of the total energy consumed. This form of electricity thrives on water bodies such as a river or dam to store water in a reservoir. Upon release from the reservoir, this water spins through a turbine, activating a generating plant which produces electricity.

Have you heard about zero electric devices? Well, while society hardly welcomes new ideas in order of their importance, everything in the energy generation industry is evolving. Also known as zero point energy, this energy source runs without any need for fossil fuels or any risks of pollutants emitting as a result of their operations. In fact, different prototypes have now been built to provide for choice, convenience, and effective cost management in the long run.

Science and engineering has come a long way. Yes, “old habits die hard”, but taking advantage of the successes achieved in the modern energy world will save us a lot now and in future. Just think, for the first time in the history of energy distribution, it can now be possible to enjoy power for free – yes, without any accruing costs or any long-term health implications. There are only positives – science is advancing and so should we.
