Reply #6: Rationing water during a drought is obvious, you're not getting the argument

Which is:
When El Niño comes, there's always drought in all the region.
When there's drought, the hydroelectric production decreases.
When that happens, you need to compensate with different electricity sources which have no relation with the drought (nat. gas, sun, wind) in order to maintain the public service.
To be able to compensate when the event appears, it's critical to invest in those alternatives with anticipation.

El Niño 2010: How does the same event affect two neighboring countries?
Colombia's hydroelectric production is reduced so they switch to gas generated electricity. They stop exporting it.
Venezuela's hydroelectric production is reduced but we can't switch, we have to cut the public service for hours every day.
