Reverse Osmosis
Rainwater, though purest form of natural water, cannot be harvested before it falls on the ground. Once it falls on the soil, it gets polluted due to mixing of soil, organic matter and mineral salts. Therefore, water from surface water sources like rivers and nallas is turbid and needs to be filtered before use.
Water Conservation in Sustainable Urban Development.
Present Status of Growing Cities
Due to rapid growth of urbanization, there is unprecedented demand for new residential constructions. As a result, old houses, vacant plots, open spaces in the urban area are getting replaced by large building complexes and multistoried buildings.
Nuclear Energy - A must for Sustainable Development of India
Solar electricity is not available in sizable amounts and the costs of collecting solar power are exorbitantly high as compared to thermal power plants using coal and so called clean energy from hydroelectric projects. Damage due to hydroelectric power stations on Ganga river prompted Dr. Agrawal to do indefinite fast. His critic of dams elaborates the impact of such dams on the environment. Rising oil prices have icreased the cost of energy. Thermal power plants create air pollution and flyash problems and add to global warming.
Intelligent Green Buildings Of Tomorrow
ABSTRACT :Adoption of Green Building Technology has become mandatory for ensuring sustainable development. However, its wide acceptance would require critical examination of various aspects like energy conservation, cost, strength and durability. Use of modern electronic controls and smart devices can enhance the functionality and performance of green building. Architects should get equipped with technical know-how for planning and designing intelligent green buildings to meet the future needs. Dnyandeep Foundation shall provide all necessary help in this task by networking and knowledge sharing through its website www.envis.org.
Controlling environmental pollution by online monitoring
Prevention and control of pollution is the main objective of state and central pollution control boards. However, in spite of various regulations and restrictions for discharge of pollutants, there is unabated gross pollution of major rivers in India due to city sewage and industrial wastes.
