Hey Doudou ! How are you ? Very Happy
I've got another text that I would like you check please ! What a Face

********************

The international situation about economy, demography and ecology lead us to refund some points of our lifestyle.
Indeed fossils energies are becoming more and more limited. One of those solutions to substitute of petrol are the biofuels.
Currently we have the first generation which is very polemic because it’s using food-producing harvests. Moreover yields are low and costs are high.
That’s why scientists are looking for a next generation to solve those problems.
What can be said about this new generation of biofuels ?
During this work we will see
- General introduction of the second generation biofuels
- The two main ways
- A practical issue : cellulosic mushrooms
- Biofuels across the world, drawbacks and beyond of the biofuels

*************

In conclusion we can say that biofuels of second generation are innovative and full advantages. Nevertheless, there are not perfect. Fields for harvest are limited and technologies won’t be expected from 2020.
However the global food crisis based on biofuel production is not completely true.
Indeed the increasing of rice prices can’t be due to biofuel production because this food is not used in biofuel industry. Whereas corn are used for that industry and its prices don’t increase.
At the time of this new generation, another way of biofuel production is envisaged: The third generation.
The international petrol situation in an imminent future do not allow us continuing in this way. That’s why we should find alternatives to change our system.
Second generation biofuel could play a major part in the production of liquid fuels but they are just one part of the general solution for the fossil energies substitution

What's up, Phil. I see you still have school work to do, but soon you'll be on vacation.
********************************************
The international situation that has arisen in terms of world economy, demography and ecology leads us to reconsider some aspects of our lifestyle.

The fact is, fossil fuels are becoming increasingly scarce. One solution to this problem is to replace petrol with biofuels.

Currently, we are using first-generation biofuels, which has caused quite a bit of controversy because it involves using food-producing harvests. Moreover yields are low and costs are high. That’s why scientists are looking for the next generation of biofuels to solve these problems.

What can be said about this new generation of biofuels? After examining these issues, we should be able to see that this topic can be subdivided in the following manner:
- The general introduction of the second-generation biofuels
- The two practical solutions to this problem, such as the use of cellulosic mushrooms and the use biofuels throughout the world
- The drawbacks of biofuels
- The question of what comes after biofuels

*************

In conclusion, we can say that second-generation biofuels are innovative and full of advantages. Nevertheless, they aren't perfect. The availability of fields for the harvesting of food products is limited and beyond the scope of technology after 2020.

However, it isn't completely true that the present global food crisis can be blamed solely on biofuel production. The increasing price of rice can’t be due to biofuel production alone because the food being produced is not used in the biofuel industry. The proof of this is that corn is being used for the biofuel industry, and its price hasn't increased.

Furthermore, a new generation of biofuel production is on the horizon. The international petrol situation in the immediate future will not allow us to continue in this way. That’s why we should find alternatives that will change our system of fuel consumption.

Second-generation biofuels could play a major role in the production of liquid fuels, but they are just one aspect of our search for fossil fuel substitutes.

No problem (as we Ricains say), my pleasure. Bonne continuation et bonnes vacances bien méritées.
