LV techno: énergie renouvelables

« LV TECHNO Hello everybody, today I will present to you the chapter on renewable energies that I did last year -first we will see what I learned, -second we will see what I preferred and what I liked the least, -third what we did -and finally how this chapter is related to my specialty and the approach of my final task 1/ First of all at the beginning of the chapter we talked about global warming, we saw why it happens.

Then we saw the different energies, the fossil energies which are energies which will eventually run out and which pollute a lot like coal, oil or gas.

After that, we saw renewable energies such as solar, wind, hydroelectric which are the 3 best know.

These energies are therefore energies which pollute much less and which can be made inexhaustible, for example hydroelectric dams, solar panels or wind turbines.

We saw how these different energies work and also their advantages and disadvantages, we learned new words related to the mechanics of a wind turbine and also how electricity is recovered and supplied to users thanks to a study conducted on its operation. 2/ What I liked the most in this chapter is the study of the wind turbine because there are plenty of them in France and I found it super interesting to discover how a wind turbine works and how the wind which is more or less strong can be converted into electrical energy with the same voltage and current.

In addition, the advantages and disadvantages that a wind turbine can have make it possible to really realize the profitability and the benefit of this renewable energy.

I find it really interesting to study this because it could be very useful to us since we really have to find a solution for the global warming which is a problem.. »
