Question

Read the given case and answer the questions that follow: CONSERVATION OF ENERGY RESOURCES Energy is a basic requirement for economic development. Every sector of the national economy – agriculture, industry, transport, commercial and domestic – needs inputs of energy. The economic development plans implemented since independence necessarily required increasing amounts of energy to remain operational. As a result, consumption of energy in all forms has been steadily rising all over the country. In this background, there is an urgent need to develop a sustainable path of energy development. Promotion of energy conservation and increased use of renewable energy sources are the twin planks of sustainable energy. India is presently one of the least energy efficient countries in the world. We have to adopt a cautious approach for the judicious use of our limited energy resources. For example, as concerned citizens we can do our bit by using public transport systems instead of individual vehicles; switching off electricity when not in use, using power-saving devices and using non-conventional sources of energy. At last "Energy Saved is energy produced"

'Energy saved is energy produced.' Support the statement.

Why is there a pressing need to use non-conventional energy resources ? Explain.

Read the case given below carefully and answer the questions that follow: National Thermal Power Corporation (NTPC) shows the way. NTPC is a major power providing corporation in India. It has ISO certification for EMS (Environment Management System) 14001. The corporation has a proactive approach for preserving the natural environment and resources like water, oil, gas and fuels in places where it is setting up power plants. This has been possible through: (a) Optimum utilisation of equipment adopting latest techniques and upgrading existing equipment. (b) Minimising waste generation by maximising ash utilisation. (c) Providing green belts for nurturing ecological balance and addressing the question of special purpose vehicles for afforestation. (d) Reducing environmental pollution through ash pond management, ash water recycling system and liquid waste management. (e) Ecological monitoring, reviews and online database management for all its power stations.
