Introduction: Basic Definitions,and its various aspects. For example, definitions of systems and properties with various units are essential to understand the change of states during energy conversions in various processes. The chapter also discusses saturated, and superheated steam tables, steady-flow, isothermal, and adiabatic p

Energy Sources,nment, while the secondary energy sources are derived from the primary energy sources, for example, in the form of electricity or fuel. Primary energies are nonrenewable energy (fossil fuels), renewable energy, and waste.

Energy Balances, while exergy are not conserved. Balance equations are for both the conserved as well as for nonconserved properties, and therefore may contain a source term. For example, in an internal chemical reaction in a system, a substance may be consumed and heat of reaction may be produced. Consequently, in

Energy Production,il fuels, such as coal or natural gas is used in steam power plants to produce electricity. Electricity is also produced by other means such as the kinetic energy of flowing water, wind, solar photovoltaic, and geothermal power. Hydroelectric power is produced when falling water turns an electromagn

Energy Conversion,perate mobile electronic equipment. A dam converts gravitational potential energy to kinetic energy of moving water used on the blades of a turbine, which ultimately converts the kinetic energy to electric energy through an electric generator. Heat engines are devices converting heat into work. With

Energy Storage,es the mismatches between the energy production and demand. For example, if it is stored the solar energy would still be available during the night. Also, the stored energy may be a supplement during the peak demand for energy. Besides, a stored energy can be transported. A battery, for example, mak
