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

SUPERCAPACITORS


Introduction


In power electronics, Electrical Energy Storage(EES) refers to the process of converting electrical energy from power into an electrical or non-electrical form that can be stored for converting back into electrical energy as per requirement.

This process enables electricity to be produced at time of either low demand, low generation cost and used at times of high demand, high generation cost or unavailability of other gener ....etc

Supercapacitors Energy Storage System for Power Quality Improvement:



Introduction
The first complete electric power system was built by the Thomas Edison in September
1882 in the New York city ;through the steam driven dc generator supplying at 110 Volt.
Due to dc system and low voltage level; the losses in transmission line (I2R) puts the
limitation for the long distance transmission of the power. After development of the
transformer and ac transmissi ....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
