Power Definition
Measure of how fast energy can be delivered
First law of thermodynamics
Energy and Matter can not be created or destroy, it can only me transform
Second Law of thermodynamics
In an isolated system, entropy increases with every transformation.
First Law of energy efficiency
the ration of useful energy output and input on a device or process.
Second Law of energy efficiency
The ratio of the theoretical minimum amount of energy to perform a task to the energy input of a device or process.
What are the energy supply options for humans ?
1- Intercept the continouse flow of solar and geothermal energy at and just below the earth’s surface. (renewables).
2-Chemical energy in fossil fuels.
3-convert matter into energy. (Nuclear)
Primary energy (Definition)
energy at its point of production (Nuclear, fossil fuel, renewables)
Secondary Energy
energy that has been processed into an input for end-use devices ( Hydrogen, electricity)
Energy Service
