he does a good job of it however if you plan to present this ... as the 'resume' for his work... then he needs to re-do it.
1- The outside scenes have too much wind-in-microphone noise. That destroys the professional impact it has on the audience and looks amateurish.
2- Scene transition is too fast and disorienting. For example, between 0:20 and 0:24 the scene goes from him cooking an egg and then POOF next frame he's in another room talking the moment the scene shifted. Then he goes from changing the thermostat to being outside. Change of scene is too abrupt.
3- the 'world without energy' scenes of him getting bored, having no car, etc have good accompanying music. but the scrolling text on the bottom is just baaad. It'd be better to use text that fades in an out at different points in the screen..it keeps the audience attention and delivers the information.
At the end of the video the 'history' of energy scrolls by too fast, and the letters block the final scene.. thats bad. again, use fade in/out text and use a font like Times Roman or Arial not that comic sans serif like font that was used. Better yet, find a way for him to NARRATE it so people dont turn their attention to reading rather than seeing the effect of a world without energy.
4- he needs to use a tripod when filming. Much of the material has the hand wobble which gives it a look as if was done by for a middle school project.
Finally.. just what exactly is the video supposed to be delivering? You mention the contest is to 'to make the world aware of the depleting energy sources' ... but how does this video tie that in with getting more clients for suez? I see no mention of what Suez has done or plans to do ...why would suez deserve the prize?
His english is very good so you dont need to worry about that. he also acts rather well.. the scenes of him bored and playing chess were great.
