The need for power and the awareness of the effect of different energy sources on the environment has grown significantly. This results in the need for better, wiser and cleaner ways to generate the much needed power. There are different energy sources that can be used to generate power and these include coal, water, wind, solar, gas, fossil fuels, and nuclear. All these and others have effects on the environment on different levels, and this may be in the gases/fumes produced, the after reactions that is the slug or slurry, ashes. The other factor about these sources of energy is that most of these are non-renewable and are the commonly used in the generation of power and are most likely to become extinct. This paper addresses methods currently used to generate power in Botswana, which is the use of coal. Since the history of power generation in Botswana this has been the only means of producing electricity. Thermal Power Station like any other power generating plant have its advantages and disadvantages, thus this paper will cover how the power is generated, conservation strategies, conversion of the coal to produce the electricity and its impact on the ecosystem. The paper will also address the alternative sources of energy that the nation of Botswana can use for power generation which are both ecosystem friendly, clean and do not require much activity. Since the focus is Botswana these sources which are solar, CBM, biogas are in abundance.
