I intended stay away of this thread, but, que diablos, I just drink one liter of Brahma Porter and I feel brave enough to say my unpopular opinion, here I go:
1.-Chile need energy
I remember my childhood and teenager years in the 60s and 70s, when Chile was a poor country socially fractured and all we dreamed to emigrate to Argentina, USA or Europe. Well, then comes the -relative- prosperity and social stability, after several years of economic growth, all this pushed for a increase on energy consumption. In those years Chile was just like is now Bolivia, a very "ecologic" country but an horrible place to live, full of poverty and social unrest. I guess that many of those who now consider Chile as a good place to settle down tend to forget that is the economic grown which underly on many of the good things that now we have. Bolivia has beautiful virgin territories, but is barely a good place to live now because of poverty, starving and social fractures.
2.-We need urgent to become as energy independent as possible
One of the most stupid -or corrupt- choices was tacked during Eduardo Frei Ruiz Tagle ruling, when we signed a contract who made Chile energy dependent on Argentinian gas. This is not possible to stand anymore, if we have any single source of energy we MUST to exploit in our benefit, it is a strategic issue of first priority because we cannot afford to depend of neighbor countries for our supply, specially considering that we compete and have conflict of interest in many fields with those countries.
3.-Any energy source has its costs and environmental undesirables
There are no free lunches, many people scandals about ugly high tension towers of power lines in Patagonia, but what about the alternatives? wind generators are far ugliest, not to mention solar farms or nuclear plants.Moreover "renewable" energy sources are -at this time- economically unrofitables and cannot survive without government subsidies, this is a self delusion because what we are paying in excess for subsidies just incentive the least efficient technologies.
4.-Chile has only two choices: nuclear or hydro
This is reality, there are no place in the world where unconventional energy sources have an important share of total matrix because their low efficiency, in many places in Europe and USA those technologies are heavily subsidied, Chile is not a rich country and, if we have to subsidie, there are thousand of more important places where to put the money, we simply cannot afford to subsidize uneficient technologies. Due the high cost of oil and high contamination of coal there are two choices: nuclear plants or hydroelectric. We still have resources for the latter and it MUST be exploited because there are well known tecnologies and the enviromental impact (who s not zero, nothing have zero impact) is lower than nuclear plants.
5.-Better technologies?
Centrales de paso instead represas? OK is fine to me, provided that there are same or better efficient in economical terms as represas. Anyway there is always a price to pay, there is not free lunch and we must be aware on that, the alternative is famine and social unrest. The country needs energy to continue working as now and we have to pay the cost, in money and environmental damage.
Anyway, I know that I am a "one man party" on that matter, but I think that this is the reality and any protest or action against to exploit the hydroelectric potential of Patagonia will be useless. We need to use this potential, the alternative is nuclear plant and it is worse, more risky, more complicated and will take too long. Hydroelectric is at our hands reach and Chilean government have to exploit as soon as possible. In the best way, looking to minimize impact. Okey, but we must use it. It is the logical and technical choice.
Oh, and "resistive loses" on transmission lines is a nonsense in technical terms. There are a very sophisticated system of "despacho de carga" developed during many, many years to solve ths kind of problems. Transmission for long distances is not a problem since several decades with the modern technologies of electric engineering.
