Assignment 1
Renewable and Non-Renewable Energy Resources for Generating Electricity
Question 1
Define the following terms: a) Non-renewable resources
Most developed nations are dependent on the non-renewable energy sources such as fossil fuels (coal and oil) and nuclear power. It means that a resources that is replaced slowly by natural earth processes in such a way that once used by people, it will not be available again within a useful time frame. Example of non-renewable resources includes oil, coal, rocks, and minerals. b) Renewable resources
Renewable resources have become a focal point of the environmental movement, both politically and economically. Energy obtained from renewable resources puts much less strain on the limited supply of fossil fuels (non-renewable resources).It mean that a resource that is quickly replaced or recycled by natural processes in a time frame that makes it useful for human consumption or use. Examples are include cotton, wood, solar energy, water. Some renewable resources have essentially an endless supply, such as solar energy, wind energy and geothermal pressure, while other resources are considered renewable even though some time or effort must go into their renewal, such as wood, oxygen, leather and fish. c) Hydroelectricity
It is a renewable energy source where power is derived from the energy of water moving from higher to lower elevations. Hydropower (from hydro, meaning water) is energy that comes from the force of moving water. The fall and movement of water is part of a continuous natural cycle called the water cycle.

d) Thermoelectric generating plants
It is any of a class of solid-state devices that either convert heat directly into electricity or transform electrical energy into thermal power for heating or cooling. Such devices are based on thermoelectric effects involving interactions between
