In relation to your plan:

Geothermal energy.
Earth :
Yes if we collect or inject hot water into the ground several hundred meters deep. This is what is found among others in Iceland. The extracted water is hot enough to be used directly.
No if we work a few meters deep. We actually recover solar heat stored in the ground. It will take a heat pump to extract this heat with a performance subject to discussion.

The sun :
Photovoltaic-OK
Solar water heater. Rather indicates "solar thermal". Solar thermal is used to make: Hot water (water heater), heat the air (Trombe walls), cook food (solar ovens and pots), dry (solar dryers), electricity (solar ovens) coupled to a steam generator or Stirling engine).
Surface geothermal energy-See above.
Wind: The wind is a consequence of the sunshine of our planet. Exploiting this energy consists of using a solar by-product.
The tidal stream: Whether it is the operation of dams and waterfalls that tidal streams immersed in ocean currents or energy collectors of swells, we recover solar energy ... This served:
Either evaporate the water so that it falls back in altitude allowing the recovery of the potential energy that has been accumulated (thanks to Earth's gravity).
Or to cause ocean currents due to the differences in temperature and salinity of the water bodies.
Biomass: Primary producers, autotrophic, use the sun as an energy source during photosynthesis. Burning wood, biomethane, vegetable oil (or animal oil since we are in biological cycles) here also consists in the use of by-products of solar energy.
I dare the last one?
Tidal energy. The tides are due to the Moon and the Sun ...

You have to integrate the house into its environment. We must mention both its design and its construction (size, architecture, orientation, isolations - natural trees, mounds included-, energy capture), as its use, whether quality of life, health, as energy then its end of life with the recovery and recycling of materials, even the rehabilitation of the site.

The subject is vast, you may need to mention these points in your introduction and then develop one or two particular aspects.

Thank you all ^^
It advances =)
I stay on the energy part it is assea complex but hey I come out ^^
Can I talk about the energy from burning wood? I read that even if this combustion releases carbon dioxide (Co2), the main greenhouse effect, into the atmosphere, it is a renewable and ecological energy because this CO2 had been taken from the environment by the tree during its growth. . A burning log renders the C02 balance null, this combustion is therefore considered as neutral from a climatic point of view: the tree eventually dies and thus releases the same amount of CO2 during its natural decomposition. Assuming of course that the number of trees used are replanting.
^ What do you think?

It seems to me that you have understood the principle.
And indeed, for this statement to be correct, a number equivalent to the sample taken must be replanted.

Hi Marie,

I would not add anything to the construction part itself, but I would like to draw your attention to a very important question: is the very concept of an individual house ecological? In the majority of cases the answer is no mainly because of the sprawling town planning and the necessary cars that this generates and especially the non viability of public transport in the subdivisions of individual houses.

The question of "thehabitat ecological "is infinitely more relevant than the question of" maison ecological ", because the house is far from being the best concept for making green housing applied on a large scale.

I invite you to think about it and ask yourself the right questions about the concept of ecological habitat, rather than dive into the technical details of construction.

And don't forget to send a copy of your report to Christophe, our webmaster. It's nice to see the result of the boost that we can give on this forum.

It is true that ecological housing would be more interesting but that includes so many things that I prefer that we remain on our initial subject ecological houses but that, in the introduction we make a generality by speaking of ecological housing to come in the special case of ecological houses.
And from there, we talk about the concept and then we establish our plan to answer the question "Why are ecological houses a necessity for the future of our planet?".

What surprised me greatly in what I said above is this: "thus releases the same amount of CO2 during its natural decomposition."
I did not know that, when dying, a tree released CO2 ?! as much as the CO2 he fed during his life?

I found some good books but I'm missing one on geothermal energy ...

And I don't know if I'm going to think of wind turbines since a minority of people install them in their gardens to feed themselves with energy.

Thanks to you =)

I let you judge the good conduct of your work. I just wanted to emphasize this important point. It can even make a nice conclusion including a questioning: the limits of the concept of individual house from the perspective of ecological housing, how to go further.

Otherwise for wind turbines in the garden, it is frankly marginal, you can save it since at these scales it produces almost nothing.

Good luck.

I put you on next link. You will be able to see that CO2 is far from being the most harmful greenhouse gas but it serves as a "standard" from which the amalgamation is often made.

You say that you mention ecological constructions in your introduction.
It seems to me that this is not the best tpe construction to have.
Let me explain, it is not recommended to introduce something that we do not talk about or very little. In your intro, you should talk about ecological solutions and then, only in conclusion, you will talk about ecological constructions. You can for example conclude by saying that all the solutions discussed are associated with each other for greater performance and thus speak of ecological houses.

Houlà Greg, don't confuse him!
Let's stick to the notion ecological habitat raised by Rulian, that is enough ...

Well, I say this just so that readers don't expect to read something they won't see.
It would be silly to have a bad grade because of that!

Now, what I say, we do what we want with it ... : Mrgreen:
