TOPIC: POWER RESOURCES IN NIGERIA

There are four major sources of power in Nigeria. These sources of power are:

- water

- Coal

- Petroleum

- Natural Gas

�

HYDRO-ELECTRIC POWER (H.E.P.): This is the power generated by water. Examples of H.E.P. projects in Nigeria are found in Kainji Dam on River Niger and Shiroro Dam on River Kaduna.

�

THERMAL POWER: This is the power generated through the use of coal, natural gas and petroleum. These minerals are used to power turbine or giant generators in other to generate electricity.

The following are places where thermal plants are in Nigeria:

THERMAL PLANT��� ��� STATE FOUND��� ��� TYPE OF FUEL USED

Egbin��� ��� ��� ��� Lagos��� ��� ��� ��� Petroleum

Ijora��� ��� ��� ��� Lagos��� ��� ��� ��� petroleum

Sapele��� ��� ��� ��� Delta��� ��� ��� ��� Gas

Oji��� ��� ��� ��� Anambra��� ��� ��� Coal

�

EVALUATION

1. Mention the places where thermal plants are found.
2. State the sources of power in Nigeria.

EFFECTS OF CLIMATE ON DAM

1. Inadequate rainfall reduces the volume of water in the rivers or dams.
2. Excessive rainfall also leads to over flow of water from the dams.
3. High intensity of rainfall leads to sedimentation of silts in dams.
4. Intensive heat also leads to high evaporation of water from dams.
