RE: A: What are the advantages and disadvantages of nuclear fusion compared to renewable sources?
There is no free lunch. This is the general rule and it is so hard to explain it to most people.
hydro power plants are quite expensive to build while still having a massive impact on the local ecosystem
I am happy to read this. People are claiming wind and hydro are the cleanest sources of energy. Which is not true at all when one accounts for the whole process, from the building to the dismantling of the plant.
PS: one efficiency unit is inverted (in the wind paragraph).
Agreed.
Externalities need to be taken into account as well.
What and where were the raw materials that were mined to build the towers and wire them up and connect them with the grid? @vath had an interesting article recently about the effects of wind towers on birds, so the impacts on the ecosystem need to be considered as well....
I think you made a typo in the Steemian name. There is no @vath. :)
Everything has an impact and we need to assess what price we are ready to pay, as the human race. Which may be complicated to implement due to our nature.
Hey!
I meant @valth... sorry!
Agreed with thinking about the overall price, of everything as well. Externalities count.
Well if you isolate only the energy gathering part of lets say the wind turbine, then yes, it might be the cleanest. Wind is pretty clean anyway IMHO. But hydro definetly impact the local ecosystem (river) in a major way for sure. You are daming the river up!
But this is misleading to only focus on the energy production process, IMO.
