An Insight into Energy Efficient Practices and Technologies

Energy and environment are two important aspects of engineering and technology which are gaining increasing importance. Both are important for sustainable growth of mankind. The effective and proper utilization of energy resources is key aspect of many process intensification studies.The concept of regeneration and cogeneration is very useful from energy conservation point of view. The waste gases and liquid streams need to be cooled before they are disposed and vented off from environmental considerations. Different modifications of existing heat exchangers, boilers, refrigerating and air condition systems can bring about huge energy savings. Biotechnology has helped in obtaining various products in energy efficient manner. The biotechnological research indicates that use of low cost material for fuel synthesis is viable and cost effective alternative. The initial high installation cost is limiting factors for this and many other non-conventional energy synthesis methods.The sources such as tidal and solar energy are being explored. Many investigations are reported on use of nanoparticles and nanofluids for heat transfer enhancements.
