Power Cycles

Energy cycles are a series of thermodynamic processes during which the working fluid undergoes changes involving energy transitions and is then returned to its original state. In this process, the working fluid undergoes changes involving pressure, temperature, and energy levels while producing a usable transfer of energy.

The purpose of any practical thermodynamic cycle is to convert energy from one form to another more useful form. Thus, the practical goals are either to convert heat into work or, in the reverse, to use work to remove heat from a cold to hot region. The classic example used to demonstrate thermodynamic cycles is the heat engine. In the heat engine, only heat and work flow across the operating system's boundaries. The engine can deliver work to external devices or receive work from an external device and cause heat to flow from a low temperature level to a high temperature level.

Power cycles are processes in which heat energy is converted to work energy. During these processes, the energy of a fuel is converted into heat energy, which in turn is used to produce electrical or mechanical energy in the form of shaft power. The processes in the cycle are governed by the principle of the first law of thermodynamics, also known as the law of the conservation of energy.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
