Biomass or geothermal?

So, let's imagine you want to install a renewable ennergy system between geothermal and biomass, in this post I will talk about the diferences between biomass and geothermal energy, so then you could judge which one is better:

Some importants points:
-For a house for a single family we would say that geothermal would need a pump to install. So from this one we would obtain energy as heat rom the subsoil- which doesn't requires a big installance and space but biomass as well only needs the space for boilers.
-A really good thing which biomass doesn't have from geothermal is that this one gives both heat and cold when its need. so with geotermal you could have a cheap air conditioning!
-Also geothermal has loads of details which are required when we want to install one; for example: the subsoil. Geothermal is more efficient with a especifics types of sol, while the biomass is more adaptable.

 So is it better biomass?
Now biomass probably looks more attractive than geothermal, but that is beacuse we are leaving the economics issues.
For 150 m we would need to pay about 30.000 if we chose to have geothermal energy but we would pay like a 10% less in case of biomass, but this is unseuful because the geothermal energy is a 4'5 more efficient than biomass which in a future would present a 40% more money saving than with a biomass.

So for example:
Imagine you have a house which you consume about 1.000 euros in gasoil for air conditioning you would pay:
    - 650 euros with biomass
    - 250 euros with geothermal
Here you seee the difference!
Also we would add the problem of the install of it. While biomass is still a burner and it keeps having problems of maintenig, geothermak has a very similar workingto a fridge, and it does presents similar problems which are insignificant.

Conclusions
All of your decision would depend of how may money we are spending on this inversion. If we haven't got a big budget i would choose biomass, but if we have a bigger budget i would choose geothermal, it is clean and reduces a lot your normal bill of air conditioning.

 Here it is a house with a biomass system

And here it is a house with geothermal system

SO.... which one would you choose?
