Hello,
Currently a student, as part of my studies, I have to make a big file on ecology . I decided to carry out my dossier on DIY which can turn out to be ecological. In short, here I am at the start of my file with already a question, what is the most ecological heating? Are solar panels really ecological until the end? From their manufacture to their end of life? Are they recyclable? Is it the same for both types of panels? Is wood heating cheaper? Will it not, in the long term, exhaust the world's wood reserves? Finally, are there other ecological solutions for heating?
So many (I hope not too much!) Questions to which I have not really found clear answers and on which I would very much like you to enlighten me .
Thank you in advance .
Jean Pierre

Re: What is the most ecological heating?
Hi Jean-Pierre. Welcome to Econology.
First, to make it easier to read the forum, can I suggest you reduce the size of your avatar image?
Then for your questions:
In case you are confused, the photovoltaic sensors are not heating systems but electricity production.
As for the gray energy of thermal sensors, it is of course not zero since glass is widely used (but recycles well).
There are housing estates in Germany without any heating system. The solar gains by the large picture windows in the south and the human activities (cooking, heating of the household appliances, ...) are enough to maintain a good temperature. And it's in Germany. the climate is less mild than in France.
Here. I hope I have answered your questions. For more details, try the "search" function of the forum. Many of these questions have already been more or less dealt with.

Difficult to answer like that. The parameters are really very many and varied. The most accurate answer would probably be: "the one we haven't installed". But I guess that doesn't really suit you ...jeanpierre59 wrote:what is the most ecological heating?
By "two types" do you mean "photovoltaic / thermal" or "flat thermal / thermal vacuum tubes"?jeanpierre59 wrote:Are solar panels really ecological until the end? From their manufacture to their end of life? Are they recyclable? Is it the same for both types of panels?

So here we change the register. Price and ecology are not linked.jeanpierre59 wrote:Is wood heating cheaper?
Unlike petroleum, wood is a renewable resource. In France, the area of forest has been increasing steadily for more than a century.jeanpierre59 wrote:Will it not, in the long term, exhaust the world's wood reserves?
The cheapest calorie is the one that you don't waste. As such, the best heating is insulation. Add to that passive solar (bay windows to the south), and you can fully cover the heating needs of a house.jeanpierre59 wrote:Finally, are there other ecological solutions for heating?

Uh, wouldn't that be an excellent insulation the most ecological heating?

Well if but a good idea must be said and repeated, right?
(in fact the truth is that I only read the first part of your answer )
