1
New cards

Continuous conversion of thermal energy

The process of converting thermal energy into work continuously, requiring energy transfer to the surroundings and a constant input of energy to maintain the cycle.

2
New cards

Degraded energy

Energy that is transferred to the surroundings during energy transformations, becoming less useful for performing work and transforming into disordered forms.

3
New cards

Sankey diagrams

Diagrams illustrating the flow of a system, showing energy input, wasted energy forms, and useful energy output to represent energy flow and efficiency.

4
New cards

Electrical power production mechanisms

Processes involving rotating coils in magnetic fields to generate electricity using generators, converting mechanical energy into electrical energy based on Faraday's law.

5
New cards

Energy density of a fuel

The amount of energy that can be obtained from a unit mass of fuel, measured in joules per kilogram (J kg-1).

6
New cards

World energy sources

Various sources including oil, natural gas, coal, nuclear, hydroelectric, photovoltaic cells, biofuel, and geothermal for energy production.

7
New cards

Renewable vs

Renewable sources like solar and wind energy, dependent on solar energy indirectly, contrasted with non-renewable sources such as fossil fuels and nuclear fuels.

8
New cards

Fossil fuels advantages

Relatively cheap, high power output, versatile usage, and extensive distribution network.

9
New cards

Fossil fuels disadvantages

Finite supply, environmental pollution, contribution to greenhouse effect, high distribution costs, and environmental hazards from leakages.

10
New cards

Nuclear energy advantages

High power output, abundant fuel reserves, and no greenhouse gas emissions during power generation.

11
New cards

Nuclear energy disadvantages

Radioactive waste disposal challenges, public health risks, uranium mining issues, and potential for nuclear weapons production.
