ABSTRACT:
Depleting fossil fuel reserves and increasing vehicular emission have forced the attention of various petroleum industries to find and alternate fuel that will power the vehicle in future based on the present day internal design as the deposits of crude oil is expected to last for another 50 years at the minimum utilization level .the proposed fuel should suitably replace the existing fuel and at the same time it should be renewable Hydrogen is one such fuel that has been proposed for the purpose ....etc

Alternative sources of energy



Why is there a need for alternative sources of energy?


The graph that you completed last time shows just how much we rely on fossil fuels

90 per cent of the worlds energy supply’s come from fossil fuels

Fossil fuels are convenient and relatively cheap – a litre of petrol in 1998 would have been 20p if there was no tax added!

How much longer can we depend on fossil fuels?

Because they are fossil fuels ....etc

ABSTRACT
A solar cell is a semiconductor device that converts solar energy into electricity by the photovoltaic effect, representing the fundamental power conversion unit of a photovoltaic system ,works under the principle of a P-N junction that absorbs light , releases electrons and holes , creating a voltage in the cell , which is then applied to load; being environmentally aware, and with the price of living rising at an alarming rate, solar power, generating energy from the natural resources of the sun, has in recent times become quite a ....etc

Swimming pools provide a great way toexercise and beat the summer heat. Buildingand maintaining a pool, however, alsomeans relatively high costs added to yourhousehold’s budget. There are severalways that you can reduce operating andmaintenance costs, lower water consumption,and conserve heat if you heat yourpool. Many people heat their pools toextend the swimming season and/or tokeep it at a temperature that they are personallycomfortable with. This lets themenjoy the full value from their pool. Solarpool heaters are an option ....etc

1. Introduction
Though any death-knell for the internal combustion engine is decades off, as fossil fuels may last upto 2050 only, we have to consider an alternative for present fuels. The world’s automakers seem to believe that the low emission, high efficiency fuel cell will eventually prove as an alternative, delivering the power and performance that customers expect. Such a high potential candidate needs suitable analysis. This paper is a modest attempt in giving the promising alternative: fuel cell vehicle. Also ....etc

Abstract:
The oil shocks of 1970s led to spiraling crude oil prices in the world market which prompted planners to view energy security as an issue of national strategic importance. Energy security has an important bearing on achieving national economic development goals and improving the quality of life of the people. World’s dependence on crude oil will continue for most part of the 21st century but the continued dependence on crude oil is loaded against it with inherent price volatility linked to finite global ....etc
