Energy is the ability to do work. There are several types of energies such as heat, light and electric energies.Energy conservation is one of the most fundamental ideas in engineering. Energy can be converted from one form to another. Energy cannot be created or destroyed. Engineers use that to improve our life standards such as producing electricity. For example, some energy-conversion systems that the engineers use, take the raw energy from fossil fuels and nuclear fuels to generate electrical power. There are four types of energy in producing electricity from nuclear fuels. First of all, nuclear energy is converted into thermal energy, thermal energy is converted into mechanical energy, and mechanical energy is converted into electric energy. Also, there is a specific engineering branch for this called Energy Engineering. They design, develop, or evaluate energy-related projects or programs to reduce energy costs or improve energy efficiency during the designing and building. Electricity is indispensable in this era so an energy engineer may work in the efficiency of hydro-electric power systems. In hydroelectric power systems, a hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy. As the water flows down through the dam its kinetic energy is used to turn a turbine. The generator converts the turbine’s mechanical energy into electricity. In those systems energy is transformed but never created or lost. It just turns to another type of energy which helps engineers to use energy more efficiently in order to improve the welfare of the society.

Fatima, congratulations, you did a good job, I understand that you talked about the conversion of nuclear energy to electrical energy. I would like to make a few comments on this point. Most of the big countries, especially the United States, France, China, Japan and Russia, these states are the countries that use nuclear energy the most. We see that many big countries use this road for energy conversion, but unfortunately this road has many damages for humanity. That's why Germany has decided to close all its nuclear power plants, and this is an exemplary behavior. If nuclear energy is not to be abandoned, nuclear power plants should definitely be reduced. For example, the United States has 96 reactors ope…
You have explained the hydroelectric power system very well. I had heard that it works with energy, but thanks to you, I learned the system in detail.
