In recent past the climatic change is detected by corresponding changes in the settlement and agricultural patterns. The climatic change resulted to rise and also downfall of various civilizations. Session on : Energy conservation. Energy conversation is the process of reducing demand on supply and enabling that supply to begin to rebuild itself. The best way of doing this is to replace the energy used with an alternative. Energy conservation technique is to reduce demand and replenish supplies.
They have to protect, develop and use alternative energy sources and clean up the damage from energy processes. Energy conservation also reduces the need of energy services and result in improvement and increased environmental quality, national security, higher savings and personal finance security.
It also lowers the energy costs. By reducing wastage and losses, improving efficiency through upgraded techniques and improved operation and maintenance energy can be conserved. Carbon taxes are employed by some countries to motivate energy users to reduce their consumption.
Tiered energy tax is employed by state of California where every user can get baseline energy allowance that carries a low tax. These programmes are created to set and protect poorer households by creating a high tax burden for the customers who uses high energy consumption. Airtight thermal insulated construction is the most prominent factor determining the home efficiency in both warm and cold climate conditions.

To minimize the flow of heat to and fro the home insulation is added but it may be labour-intensive to fit to an existing home. Asian governments have implemented a range of subsides such as grants, cheap credit, tax exemptions and co- financing with public sector funds to encourage energy efficiency across several sectors. Session on : Waste-to-energy. The process of generating energy in the form of heat and electricity from primary treatment of waste or process of waste to a fuel source is known as waste-to-energy.
Generation of electricity and heat is done directly through combustion or produce a combustible fuel commodity, such as methane, ethanol or synthesis fuel. Development technologies foe processing residual solid waste has only become a focus attention in recent years stimulated by the search for more efficient energy recovery. Incineration is the main method of the energy recovery. Other new emerging technologies are able to produce energy from waste and other fuels without direct combustion. These technologies have a great potential to produce more electric power from the same amount of fuel but this is possible through direct combustion itself.
