When we look up the word “sustainable” in the dictionary, we would see that it means “able to be used without being completely used up or destroyed.” So, when someone mentions the words “sustainable energy”, we would immediately think that it is an energy that can never be completely used up. Pretty awesome, yes?
Sustainable energy comes in many forms. This would include solar energy, tidal energy, wind energy, hydroelectric energy, biomass energy and geothermal energy. All of these energy sources can be used to sustain earth’s needs for a very long time without us worrying about running out of supply. That’s what makes these sources of energy awesome—they are virtually limitless. Imagine what humanity can do with that much power?
Even if it seems that we have only recently heard of these sources being used for power. These energy sources have actually been used since ancient times.
Since the beginning of civilization, human kind has been looking for ways to improve they way of living. From food production to transportation, man realized that they need energy to survive. So they turned to valuable resources for energy. If we think about it, ancient civilization didn’t have any hi-tech equipment, yet they were able to use resources to help sustain their lives. They used solar energy to dry and preserve food, and also for agricultural processes. These people also used wind energy to help with the movement of their ships.
They burned dried wood, grass and cornhusks to cook their food and also to keep warm. Even if they didn’t think much about it, they knew that these energy sources were important.
As time pass by, this knowledge has been passed on, with each generation adding improvement to the efficiency of harnessing the power of these resources. Various inventions were created and additional discoveries were made. Some of the greatest thinkers of the generation worked together to give modern civilization what they needed; unlimited energy.
With this unlimited energy, society’s indifferent parts of the world have managed to improve their ways of life, and not to mention, improve their budget status as wee. Even fitness equipment can be charged with solar energy nowadays. I have a small fitness in my garage and I am able to power a very good cheap treadmill that I bought for $300. The advances in technology also have made possible for the average home owner to obtain the equipment needed to be able to be self-sufficient in terms of electricity production for their daily needs.
Different countries have been striving to be able to improve the energy-harnessing capabilities of their technology. Once improved, societies would be less dependent of non-sustainable energy sources and rely solely on sustainable energy
