Energy has been used ever since it was first discovered. It is one of the most useful and used source of element in this world. Energy is converted from one form to another, but is never created or destroyed. It is used to create electricity, heat, oil, natural gas, and coal. Energy is a "scalar physical quantity" that is a property of systems and objects conserved by nature. It is the ability to work and to make things work. It is a substance that comes in different forms such as thermal, radiant, mechanical, chemical and nuclear forms.
There are many types of energy; solar, biomass, hydro power, ocean energy, wind, geothermal energy, uranium, and fossil fuels. And in this world, energy is used in everything. Energy is needed to play sports, make food, and travel to space. "Energy is there to make sure we have the power to do it all." No, it is not wrong to use energy; but it is wrong the way one uses it. With the technology today, energy would be used twice as much. Energy plays a very important role in our everyday lives and society,it is also a very limited resource; we need to learn how to renew and conserve energy before it runs out.
