Strategies For Sustainable Development

Transcript

Different Sources of Energy Conventional Sources Sources of energy which are normally used Since long period of time Example Thermal Energy Hydro Energy Problems Causes Pollution Limited Supply Doesn’t cause Sustainable Development Advantages More used as technology easily available Non Conventional Sources New Sources of energy which have not been much used due to lack of technology Example Solar Energy Wind Energy Advantages Environment Friendly Abundant Supply Leads to Sustainable Development Problems Less used because of lack of technology Problems with Conventional Sources of Energy Thermal Power Plant Coal is burnt to Generate Electricity Problems Burning Coal Releases Carbon dioxide It is a Green House gas Raises Temperature Causes Global Warming Fly ash also produced Contaminates Land and Water Coal Reserves available in Limited Supply Will be exhausted in future Hydel Power Plant Water is used to Generate Electricity Problems Dams are Created to block flow of water Natural flow of water is disturbed Forests are flooded Lead to loss of Habitat for Plants & Animals Why Non-Conventional Sources of Energy To Be Used? Wind Energy Electricity generated using Power of Wind Benefits Available in abundant supply Will not be exhausted Doesn’t cause Pollution Solar Energy Electricity Generated using Sun's energy Benefits Available in abundant supply Will not be exhausted Doesn’t cause Pollution
