The quest for green energy technology and environmentally benign energy sources has intensified globally in the recent time. Most of the world countries are now prospecting on alternative energy sources that can substitute the conventional fossil fuel energy. The use of fossil fuel in the production of energy as resulted in both environmental and economic effects in the world. The rise in the global pollution trend and the increased incidences of global warming as a result of fossil fuel combustion, not withstanding the high cost of this fuel source since it is found in the boundaries of few countries are just but a few effects. Wind energy is arguably one of the alternative energy sources that can help meet the energy demands of most population of the world and also aid in the mitigation of climate change effects. This research paper therefore seeks to explore the history, cost, merits and demerits, and the future of wind power.
