Comparison among renewable energy sources
Brazil is a country that has abundant renewable sources.
How do they compare?
There are many factors at stake. This post only compares the typical production of the same installed capacity in relation to the energy each source delivers.
The graph shows that hydro energy is the most competitive in this regard and solar energy the least. The wind is located in the intermediate zone.
This finding is important because the three sources require approximately the same investment per installed capacity.
Hydro has the highest energy production per installed capacity. The solar one is the smallest, as it only operates when there is sun, of course.
