Energy and types of Energy


Energy is the ability to do some work.We know also that all things around us need energy to move. When we apply a force onto an object, we are using our muscular energy.  There are several types of energy, depending on where they come from: The first one is electrical energy, an example of it is our light bulbs, the tv or the air conditioners we use at home. The second one is heat energy, coming from fire(as an example) or the 90% of the electrical energy that become heat energy in our light bulbs(that's why they are warm when we touch them). When we move objects with our hands, we use our muscles, so it is called: muscular energy! If we imagine we are doing some sport at the park and it is very sunny, we can understand how Solar Energy does affect us, and how they can be stored into solar panels. The last two types of energy are: hydel energy, coming from moving water and wind  energy(come from moving air and obtained with windmills).
