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

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