SOLAR ENERGY

TRADITIONAL METHOD:

Here silicon is used as the material to convert the solar energy into electrical energy. This is was the primitive method used to convert the solar energy into electrical energy. As it posed few drawbacks that makes it unfit to be used at a larger area.

DRAWBACKS:

* COST of production of solar cells was too high.

* Even 99.5% pure silicon doesn't provide that efficient solar cells.

* Always requires flat surface for installation.

* And many more

LATEST METHOD:

Here we use polymer material instead of silicon, which has wide advantages.

The process is similar to the traditional one, only the material is changed.

ADVANTAGES:

* COST of production is very low.

* Easily available, as it is similar to polythene.

* Can be made of any shape and any size, & can be used under any adverse conditions.

* Efficiency is also high, if research is carried on this and it is sure that even our mobile phones will be using battery of this material.

* Mainly it is eco-friendly.

So by using such eco-friendly materials we can save our earth & natural resources.

 

VARIOUS RENEWABLE ENERGY AVAILABLE

As we were talking about the renewable energy, there are various renewable energy that are available.

Those are listed as follows:

* SOLAR ENERGY

* THERMAL ENERGY

* WIND ENERGY

* TIDAL ENERGY

Out of these only solar energy is providing maximum energy and also this is available in abundant in nature.
This is everlasting one too.

Use this and save our earth & natural resources.

NEED FOR RENEWABLE ENERGY

As everywhere there are huge problems of energy & and its conservation. Day by day the amount of fossil fuel available on this globe is reducing down, at the same time the popullation is increasing rapidly. Due to this the demand for energy is going on increasing.

Now we are attached too much to energy that we require it 24x7. Imagining life without it is like fish with out water. If this energy gets exhausted then our life is unimaginable. So this brings the need for renewable energy.

Renewable energy is the one which we can rely upon as it is available in abundant.

All we have to do is find various effective renewable energy that can replace the existing fossil fuels. This will only help us to live with energy.

So use renewable energy and save our earth & natural resources.

INCREASE IN POLPULATION INCREASES GLOBAL WARMING

As the population of the world is rising tremendously, the usage of fossil fuels is also high, which in turn leads to lot of emission of green house gases in to the atmosphere.

This has been todays major problem causing global warming.

All we have to do is control population growth

& save our earth & natural resources

VARIOUS SOURCES OF GREEN HOUSE GASES

Most of you would be aware of various sources of green house gases. These are very common like, mainly industrial effluent, fossil fuels, etc.

but even sulphur in the form of  trifluoromethyl sulphur pentafluoride (SF₅CF₃) is also contributing to various green house gases.

So we have to save our earth & natural resoures

trifluoromethyl sulphur pentafluoride (SF₅CF₃) fossil fuels, methane from farm animals, forest destruction, rotting/dead vegetation

SOLID WASTES POSING PROBLEM

Solid wastes is now posing huge problems to this world. Especially its disposal and its management.

As the human population is increasing tremendously along with land surfaces getting sub merged under water, the land portion available for normal living has been reduced.

Along with this many solids which cannot be recycled & reused needs space to be dumped, which finds difficulty in availability & also poses problem to everyone in the environment.

This is also a contributor for increase in global warming.

Also these solids consume huge energy & cost to recycle.

All we have to do is to produce such goods which can be recycled by faster, cheaper means.

We all have to SAVE OUR EARTH & NATURAL RESOURCES

DECLINE IN DRINKING WATER LEVEL-GLOBAL WARMING

Another problem caused by GLOBAL WARMING is the reduction in drinking water quantity.

Global warming is melting the ice caps & letting the fresh water to get mixed into the oceans which is not favorable for drinking & even many purposes.

This along with drastic increment in population and demand for water requirement creates greater problem.

So SAVE OUR EARTH & NATURAL RESOURCES

ENERGY CRISES

Energy crises is a huge threat to the people on the earth.

As we are so attached with it 24x7 throughout our life, now its very difficult 4 us to live with out it.

Just imagine 1 day, only one day without energy, how disaster your life would be without it.

The reasons are many for this energy crises.

As the non- renewable source of fuels are distributed unevenly throughout the world along with population explosion it has created a dead line for the availability of fossil fuels.

Now we have to save our earth & natural resources.

For this all we have to do is find an alternative source of energy and that to renewable source with sufficient efficiency.

In this search mostly we can go for solar cells, as every1 knows solar energy is abundant in nature and can be utilized.

But now we have to implement few modifications on the previously available techniques in order to minimize its drawbacks.

For example the conventional solar cells were made up of silicon cells, which had high production cost.

Now we can replace those inorganic materials by organic polymer, which will reduce the cost of production and is also easily available at low rate.

Even it possesses various merits that it can be used in any environmental conditions any could be used in any shapes.

So developing such type of alternative source of energy that to renewable source would help us to fight against such energy crises.

All is in our hand, we have to SAVE OUR EARTH & NATURAL RESOURCES.

LETS DO IT!!!!!!!!!!

save earth

HEY FRIENDS WE ALL HAVE TO PLANT ATLEAST TWO SAPLINGS PER HEAD TO REDUCE THE EXISTING AMOUNT OF GREEN HOUSE GASES IN THIS ATMOSPHERE


TREES HELP IN ABSORBING THESE TOXIC GASES & HELPS IN THE REDUCTION OF GREEN HOUSE GASES, WHICH IN TURN REDUCES GLOBal warming

save our earth

SAVE OUR EARTH & NATURAL RESOURCES

All we have to do is conserve in what ever we do.

Always try to save something for others also, let it be energy, food, etc.

Also try to save natural, non renewable resources, by optimized utilization so that our future generation can also enjoy these natural resources.

Also we should always remember that we don't have any rights in disrupting the natural resources which is common to all.

So as a HUMAN we must enjoy our facility and also let others enjoy theirs.

So we are responsible for what we are.

EVERYTHING THING IS POSSIBLE IN THIS WORLD.

But it would take time & effort.

Lets all put in our effort to SAVE OUR EARTH & NATURAL RESOURCES.

ACIDITY KILLING AQUATIC LIFE-GLOBAL WARMING

A recent survey shows that the global warming, which is caused by green house gases has increased acid rains in the globe.

This acid rains decreases the pH of aquatic water, which in return will affect the aquatic life.

Due to such acid rains many of the aquatic species gets exhausted and many aquatic life has even missing in this world.

So we have to control th eemission of green house gases.

CONVENTIONAL FARMING - CONSUMES GREEN HOUSE GASES FROM EARTH

IT WAS FOUND THAT, conventional farming has consumed a greater amount of green house gases.


By doing conventional farming, the scarcity of the food crops can be solved at the same time the amount of green house gases can be reduced from the atmosphere.


This is something great, we can achieve two things at a time.


So i would request u all to promote conventional farming and contribute to reduce both famine and green house gas concentration on earth


SAVE OUR EARTH 

FAMINE----- GLOBAL WARMING

EFFECTS OF FAMINE

Apart from various problems caused by global warming, there a new problem that got added to the existing list is FAMINE.

The global warming if it continues its trend then its expected that globe's 50% would be facing food shortage by a century.

The reason behind this is very simple, the global warming will affect the climatic change, this will result in drought which will affect the agriculture and there by resulting in scarcity of food.

The tropic and the sub-tropic regions would be immensely affected by it.

The reason for affecting mainly the tropic and the sub-tropic region is decline in food production i.e. agriculture also at the same time rapid growth in the population is addition key to it.

So global warming does not a single problem, in turn it forms chains of problems which are related to one another.

From this it is crystal clear that, by controlling global warming we can solve most of the global problems on this earth.

For this we all have to contribute our level best.

SAVE OUR EARTH



 

CORAL BLEACHING CAUSED BY GLOBAL WARMING

CORALS BEFORE BLEACHING

CORALS AFTER BLEACHING

CORAL BLEACHING means whitening of the corals, this is due to the symbiotic algae which live on it leave it.

The reason behind is GLOBAL WARMING.

The temperature under the water is found to be around 34 degree centigrade, which is around 3-4 degree greater than the normal water temperature.

This rise in temperature has lead to coral bleaching, which in turn has resulted in death of around 80% of the species.

If this continues then coral would be completely bleached within few months.

This is mainly found near Indonesia.

These losses in coral will affect the food chain of the aquatic life, also will increase the under water temperature.

This will result in various natural calamities, which will affect everyone.

So we have to bring back coral reefs so that the under water temperature remains steady and also the aquatic food chain is not affected.
