Identify The Alternative Source of EnergySome of them are listed below: Solar Energy Bio-Mass Energy Nuclear Energy Geo-thermal Energy Tidal Energy Wind Energy Wave Energy Hydro-Electricity Compressed Natural Gas Radiant Energy

First Step To Save The World

Types of Energy

Generally There are Two Type Renewable Source of Energy

Those source of enrgy which is found in adequate amount in earth

Non- Renewable Source of Energy Those source of energy which are limited in earth's

crust

SOLAR ENERGY Energy obtained from sun which is infinite(forever). Merits: found in adequate amount, do not use up natural resources or harm the environment, does not cause pollution, oil reserves will last for 30 to 40 years.

Demerits: can only be harnessed when it is daytime and sunny, Solar collectors, panels and cells are relatively expensive to manufacture Large areas of land are required to capture the suns energy.

WIND ENERGYEnergy collected from motion

caused by heavy windsMerits: a green energy source and does not

cause pollution,Wind turbines are incredible space-

efficient ,The potential of wind power is enormous

Dmerits: Wind turbines can be a threat to wildlife (e.g. birds, bats), Wind is a fluctuating (intermittent) source of energy and is not suited to meet the base load energy demand unless some form of energy storage is utilized (e.g. batteries, pumped hydro).

HYDRO-ELECTRICITYElectricity generated by hydro-power;use of the gravitational force of flowing water.Major source energy in Nepal.Merits: Renewable Green Reliable Flexible Safe

Demerits: Environmental Consequences Expensive Limited Reservoirs Droughts

BIO-MASSOrganic matter from plants and

animals (microorganisms),

Merits: Renewable Carbon Neutral Cost-Effective Abundant

Demerits: Expensive Requires Space

SOLUTION OF ENERGY CRISISAll the thing required is the technologies to convert these abundant resources into useful energy.

Some of solution are listed below:We should be concious about conservation of enrgies.

WHY FOSSIL FUELS ARE WIDELY USED IN WORLD?

Merits:Easily availableProduce large amount of energyHigh caloric valueStabilityTransportationLow costEasy set up

Demerits:PollutionAcid rain(co,so2)Destruction of wide areas of landGlobal warming

CONCLUSION

I concluded that the alternative source of energy is any source of energy which is used instead of fossils fuels such as petroleum products which are limited in quantity.Only can be solved if the natural resources such as sun,flowing water, blowing winds,bio-mass materials,etc are used properly.

Thanksto all for Listening
