Our way of life needs a lot of energy, more and more: airplanes, refrigerators, cars, computers, cell phones, etc. All human activities require energy, but to obtain this energy we must transform sources, such as the sun or the wind.
We call these original energy resources Energy Sources.
These sources are natural resources that can provide electricity, heat or movement.
There are two definitions of energy that refer to its origin:
Usually these two definitions are used when referring to electric power generation, however, these resources are often used to obtain heat.
Renewable energy is energy that comes from inexhaustible sources. Examples of these forms of energy include solar, power and hydropower, among others. They generally come from a natural resource. Resources such as solar radiation can be transformed into energy without being depleted.
The non-renewable energy source comes from limited sources, which means that the consumption of resources is greater than their regenerative capacity, so they are depleted as we use them. Examples include fossil fuels (coal, oil and natural gas) and nuclear reactors, among others. As for the latter, nuclear power plants have a high energy generation capacity; however, uranium is a limited natural resource.
Today, our energy needs make all these sources indispensable.
