Compare cost of kW of energy




by All gas » 24/09/08, 15:24

Hello,
It is very difficult, without being a specialist, to have a precise opinion on the interest of a system using a so-called renewable energy.
We must not forget what Lavoisier said "Nothing is lost, nothing is created, everything is transformed"
Heat cannot be "pumped", it is transferable from one place to another.
To compare the final cost price of kW for various energies, you must first know all the elements of the calculations such as: the DJUs for the heating season, the ambient T ° to be maintained as a function of energy losses, etc., etc. .... then implement complex calculations but the result is worth it.
The software offers the possibility of carrying out all of these calculations without knowledge of the field and makes it possible to quickly know if the investment is realistic.

Do you spam by forgetting the link? What software? What are you causing?

Here is a comparison of the cost of energy: https://www.econologie.com/chauffage-com ... -3584.html

Do you not feel stupid to "advertise" while confusing kW (unit of power) and kWh (unit of energy)?

Hello,

I find your comments really inappropriate, you are not very moderate for a moderator!
The tu without knowing people is disrespectful.

In my message, when I talk about software, it is generally, I advise you
read the messages carefully before intervening without valid reason.

In addition, you obviously do not need me to advertise this forum.

Regarding your remark on the kW, I would like to point out that the kWh is the instantaneous power per unit of time, the kW is the instantaneous power.
At a precise instant, and depending on the working environment, any system producing, transforming, displacing energy provides instantaneous power in kW and not in kWh.

In most cases, kWh allows energy consumption to be quantified on the basis of a physical meter according to a so-called removal tariff grid, as for EDF / GDF.
For fuel oil for example, this is not possible, in this case, an hour meter is installed on the burner which totals the number of operating hours which is multiplied by the instantaneous power in kW delivered by the latter, there we can speak of kWh.

You see, we're still someone's jerk.

Greetings and thank you for leaving this post.

And so? What do you want to sell? Because that's what it's all about isn't it?

I think Christophe was talking about your sentence quoted above and the title too.
You can't calculate the price per kW (as you defined it right after) it doesn't make sense. By cons of kWh which is a measure of energy yes.

Well we can speak in cost of kW but it is not Energy but an investment cost:

Examples:
a) a 3kW petrol generator sold for € 600 at a cost of 600/3 kW = € 200 / kW
In comparison
b) a wind turbine has a cost per kW of around € 1000 / kW
c) a nuclear power plant is around 1500 € / kW

In the title of the subject it is well noted "cost of Kw of energy" ...

Yes I agree but then it’s not energy as you said, that’s what I wanted to say too : Cheesy: , calculating the cost of kW of energy didn't make sense.

Hi ToutGaz!

Sure it's a job, but you have to start by consuming less.
what software is this?

"Consumption is similar to a search consolation, a way to fill a growing existential void. With, the key, a lot of frustration and a little guilt, increasing the environmental awareness." (Gérard Mermet)
OUCH, OUILLE, OUCH, AAHH! ^ _ ^

Back to "hydraulic, wind, geothermal, marine energy, biogas ..."
