Coup de main(s) lettre motiv anglais

Since my childhood I have always been interested in science and technology but I never really saw a future job.
It was only four years ago now that I became interested in humanitarian and development of green energy, so I applied for a BTS Air Conditioning and energy and within the volunteer fire department of Essonne in France. I hope to be able,in the future, to help up my fellow citizens as aider and also improving the production of our energy by making their products less harmful and less risky.
Recent events in Fukushima in Japan made me realize that it is important that a radical change in the production of our energy to do to move towards cleaner production and less dangerous to humanity and our environment.
Moreover, this work as volunteer firefighters requires qualities such as improvisation, seriousness, perseverance, discipline, adaptation and a great sense of honor.
These qualities will I be a big help in my studies. So I chose my courses of study in order to achieve my goals for my future, both in terms of my professional career in clean energy, but also among volunteer firefighters.
