Energy and Cogeneration
- 1.1k Downloads
The word energy is derived from the Greek in (in) and ergon (work). The accepted scientific energy concept has been used to reveal the common characteristics in diverse processes where a particular type of work is produced. At the most basic level, the diversity in energy forms can be limited to four: kinetics, gravitational, electric, and nuclear.
Energy is susceptible to being transformed from one form to another, where the total quantity of energy remains unchanged; it is known that: “Energy can neither be created nor destroyed, only transformed”. This principle is known as the first law of thermodynamics, which establishes an energy balance in the different transformation processes.
When the energy changes from one form to another, the energy obtained at the end of the process will never be larger than the energy used at the beginning, there will always be a defined quantity of energy that could not be transformed.
