Energy of wind can be used for thegeneration of electrical energy.

A wind mill converts the kineticenergy of moving air into mechanicalmotion that can be either use directly torun the machine or to turn thegenerator to produce electricity.

Wind energy which is an indirectsource of energy can be utilized to runwind mill which in turn derivegenerator to produce electricity.

BIOMASS ENERGY

B iomass is a re newable source of e ner gy because t he natural process of photosy nthesis co nstantly pro duces new or ganic matter in the growt h of treesand plants. Photosy nthesis stores t he su ns ener gy in or ganic matter . B iomassis use d to make heat, electr icity and liquid fuels .

B iomass is solar e ner gy store d in or ganic matter .

B io gas is generate d through a process of a naerob ic digest ion of B io M ass . B io M ass is or ganic matter pro duce d by pla nts, bot h terrestr ial (t hose grow n on land) and aquat ic (those grow n in water ) and their der ivat ives

. It includes forest crops a nd residues, crops grow n espec ially for t heir ener gycontent on e ner gy farms a nd animal ma nure .

The co ncept has bee n prove n in numerous small scale appl icat ions. The rece nt infus ion of power cost from foss il fuels may co nvert t his prom ising device into a major source of electr ic power generat ion.

It is pre dicted that if the fuel cell clears a number of tec hni cal hur dles a nd provesf inancially v iable, it coul d contr i bute 20,000 M W power to t he S gr id, by t he end of 1985 .

F uel Cells are eff icient and quiet, operate o n a var iety of hydrocarbo n fuels, a nd pro duces almost no object ionable em issions.

ADVANTAGES

The fuel cell co nverts its fuel directly to electr ic power . Polluta nt levels ra nge from 1/10to 1/50,000 of t hose pro duce d by a foss il fuel power pla nt as t here it no combust ion

No cool ing water is needed so it ca n be locate d at a ny desired place .As it does not make noise. It ca n be rea dily accepte d in residential areas .

The land requ ireme nt is co nsiderably less compare d with conventional power pla nts.

F uel cell power pla nts may furt her cut generat ion costs by el iminating or re ducing linelosses . The ma intenance char ges are low as t here are no mov ing parts a ndouta ges are also less .

The we igh t and volume of t he fuel cell is co nsiderably low compare d toother ener gy sources .
