Supply Demand Rapidly increasing Electrical Energy Flow Consumers (Demand or Load) e.g: Lighting -Computer/IT Equipment -Industrial Processes Power Generation (Thermal, Hydro-electric, Nuclear) (Supply) Or Non-conventional (Solar PV, Wind etc) Transmission and Distribution Network (T & D) Load-shedding? Demand is more than supply (Basically a Power Shortage/Power Cut) Ideally... Supply=Demand (Power-generated=Power-consumed) Increasing supply rapidly is very difficult
Generation-waste affects the mother environment
Challenges involved...!! • Increasing generation is difficult... • Raw materials, water, environmental effects of generation waste, manpower, economics... • Even if generation is increased, similar complexities involved in modifying T & D network for increased capacity is equivalent to broadening the roads for carrying more number of vehicles...one can imagine!

Why Switch-off? I am worried about my successors (students/researchers) who are coming to our university in the future…hope they will not experience any load shedding…it will affect their studies and nightlife in Manchester… I am worried about football/cricket/rugby fans/players in Manchester… I am worried about the patients in hospitals.... I am worried about the Power Shortage developing countries are facing and developed countries may face (ultimately effect is/will be global…) Are you worried about anything? Don’t worry… Just switch off the lights and electrical appliances when they are not required and be happy ...and you become an Environment Champion
