Wind turbine

A wind turbine is composed of a tower, 3 blades and a nacelle with all the mechanism. The wind turns the 3 blades and leads an engine wich transforms the wind energy into electricity. This electricity is stocks in batteries or sents to the electricity network of the companies of electricity. A wind turbine is very ecologic because it reject no pollution and it makes renewable energy. On a year, it works 3000 hours and produces 2 or 5 Megawatt. Every wind turbine reduces 20% of the CO2 emissions normally rejected. Wind turbines are placed on big zones without obstacles to get the wind : in the sea(offshore), on big lands, in mountains... You can have your own wind turbine but it's very expansive.

But there are a lots of disadvantages like: the landscape, the place, the aerial traffic, the noise , the conservation of the site...

Rustle the leaf ;  an ecologic and humoristic cartoon

Rustle is an ecologic leaf and he speaks with his friend the acorn about the pollution. Rustle is sad and he things at the power of the nature indeed the power of the nature could change people. And the acorn answers that hitting them with rocks is outta the question. This is a question that all the nature search the answer.

Indeed enter the deforestation and the pollution the nature is very patient and she haven’t got a doctor for her ! The humains contribuate at the destruction of her. In paris there is 170 micrograms of dioxide per cubic meter in the sight. The pollution is everywhere.

Now there is more and more people who try to protect the nature and who militate against the deforestation but there was too much pollution before we realized it and now a big hole in the ozone layer threaten us. There is many solution for limit the pollution but no one to repair the problem already committed : there is Wind turbine,limitation of driving  in certain city has certain moment of the day and ofher things.

Solar panels : a sustainable energy !

They’re large and flat and they’re two main forms of them: solar electricity panels (which generate electricity for our homes) and solar hot water panels ( to heat the water we use). With solar panels, there’s no pollution, so, no carbon dioxide, no nitrogen oxide, no pollution! And that’s great! It’s the most clean and green energy, it’s helping to protect our environnement. But the major disadvantage of installing a solar energy system is the price and that It requires a large area for installation to achieve a good level of efficiency too. To finish, solar panels are becoming increasingly popular around the world. So, we can say that more solar panels can easily be added in the future, when your family’s needs grow…

Reusable bags are objects answering to the idea of going green because they act for the sustainable development. They allow to replace plastic bags and paper bags, which have serious consequences on the environment. Indeed plastic bags destroy the landscape beauties because people dump them anywhere. Moreover, it takes about 1000 to disappear, they kill a lot of marine mammals and they are made of some rare oils. Paper bags are harmful to forests because every yea millions of trees are cut down to produce paper bags. As a result, people have to use reusable bags in order to save wood, oil and preserve nature. Reusable bags don't harm the environment during their production and don't need to be discarded after each use. they are recyclable and affordable.

I have chosen the washable layers, in French “couches lavables.” I have chosen this because, for me it’s the best object for the economy and the ecology.

From birth to the cleanliness, the disposable layers for one child use:

                                                 - 4.5 trees.

                                                  - 25kg of plastic, so 67 kg of oil.

                                                 - About 20 liters of water

                                                 - And many chemicals

About, one child use 6 layers per Day.

From birth to cleanliness, a child uses about 5000 layers.

In France, there are 1,8millions of children who use layers equivalent at

2, 7 milliards of layers.

A disposable layer will take about 500 years to degrade. Among these 500 years, it will produce methane and toxic’s gases.

How use a washable layer

1)    The baby use the layer

2)    You take the saddle layer and put this in the WC

3)    You rinse the layer and you put it in the washer.

4)    After you let dry the layer

5)    You put a new saddle layer

6)    And you can reuse it.

To create a washable layer, we do not use many chemicals.

A washable layer will take about 6 month to degrade.

On average 1 washable layer cost 10 Euros but 5 disposable layers cost 1 euro.

A child needs to 5000 layers

We must pay 1000 euro for the layers of one child, if you take disposable layer.

We must pay 250 euro for the layers of one child, if you take washable layers.
