Costa Rica Goes 75 Days Powering Itself Using Only Renewable Energy 317
An anonymous reader writes with news about an impressive renewable energy accomplishment in Costa Rica. Costa Rica has achieved a clean energy milestone by using 100 per cent renewable energy for a record 75 days in a row. The feat was achieved thanks to heavy rainfall, which powered four hydroelectric plants in the first three months of the year, the state-run Costa Rican Electricity Institute said. No fossil fuels have been burnt to generate electricity since December 2014, in the state which is renowned for its clean energy policies."

China can pull off something like the Three Gorges project because it's heavily central planned and controls dissent, but I don't think you could get that to fly in the U.S., even if the major environmental groups disappeared tomorrow.

On the other hand, I spent a few months in Panama and then returned to CR for a holiday, and when I picked up a pizza that I had ordered, the guy said "Have a nice day," that is, "pura vida". And he meant it sincerely. At that moment, the difference in attitude was shocking; I had been used to Panamanians (although I prefer the sobriquet Panamaniacs :P) basically looking at me as a business opportunity at best.
The average Costa Rican does not have a computer, although cell phones are relatively common. Computers are quite expensive, enough to make an import business profitable, but very few people can afford one. There is a 100% import duty on cars, so those are expensive too. They also do a license plate restriction on driving, at least in San Jose. Most have electricity and relatively clean water, although they do have an issue with dumping raw sewage into almost all of the rivers. I wish I could more effectively describe the impoverished living conditions; if you have any specific questions please feel free to ask.
On the other hand, people sure don't care about working hard there. My friends in San Jose tell me that the weekend starts on Thursday, and everyone including the boss is late on Fridays and Mondays. There were as I recall a couple clubs where you paid a $10 cover and drinks were free. If there was paperwork that needed to be processed by the government, let's just say the Vogons would be proud of the Tico bureaucracy. If you needed to have your car repaired by a certain date, the Ticos will of course be delighted to tell you that it will be ready then, but no amount of inducement or cajoling will actually make it ready by a given date. Things happen when they happen, and no one is in a hurry to get anything done or to go anywhere — they call it operating on "Tico time".
However, all that said, I'm a little skeptical of the article. Most of Costa Rica is really rural, and I would be surprised if the national power grid actually extended to all corners of the country. I don't think that the average Tico really cares about environmentalism; to some degree it's a first world problem. The Costa Rican government on the other hand knows that the country basically has no industries; the farming isn't great and I believe tourism is the biggest part of the economy. Costa Rica doesn't have all that much to tour, either: there are no mayan or aztec ruins, and almost nothing in the way of indigenous culture. I heard something about painted oxcarts being a thing, but never saw one. Contrast with Panama's amazing diablo rojos (the buses or the costumes [staticflickr.com]). So some while back they hit upon the idea to market themselves as a destination for "eco-tourism", which involves convincing the rest of the world that they have some sort of unique level of biodiversity. It may even be true. However, they really need to promote the image of being green and eco-friendly regardless of the truth.
If I could make a decent living there it'd be hard not to go back, even though the world is full of things I have never seen before. Whether or not the Ticos are the happiest people, I think that I can safely say that happiness for me is two-for-one mango daiquiris at the Lazy Mon. Pura Vida!

Well to be fair, there is a certain irony about calling the energy "renewable" when it couldn't be sustained.
Still, it's an impressive accomplishment that they pulled it off as long as they did. It should be noted though that:
1) It's not replicable everywhere at any time.
2) Costa Rica doesn't have particularly demanding energy needs (as the "stupid" guy above pointed out).

You can still deplete your supply of renewables by using more than the refill rate - at least temporarily.

That's true to some extent but not on human time scales. Much of the coal was laid down at a time when microorganisms hadn't yet figured out how to break down cellulose so it wasn't decaying to something that wouldn't become coal. That is no longer true.

I'm pretty certain that's redundant, as all "renewable" sources have "unpredictable" problems, except tidal.
- Hydro - dry spell, loss of snow pack
- Solar (PV & other) - oops clouds
- Wind - still day
"unpredictable" is the nature of renewable sources, which is why other baseline or backup sources (such as safer nuclear) remain vital as we figure out how to move away from fossils

It's always sunny somewhere, it's always blowing wind somewhere. And often when it's not sunny it's windy and vice-versa.
The solution to renewable power fluctuation is an interconnected grid at to make it feasible and profitable to time shift power. That's it. Germany is proving very effectively that solar and wind don't need huge backup generation capacity. Renewables can provide all the energy we need and the energy companies hate that idea (it will mean dramatically less profits) so they spend a lot of t

There's a reason why we have both the words "renewable" and "sustainable" - they do not mean the same thing.
Costa Rica will get more rain, which will "renew" the reservoirs behind the hydro dams. It's not raining 100% of the time, and the hydro dams release more volume of water than the rain provides in the same unit time, so it's not completely sustainable. But it is still a renewable resource.

"Renewable" means no finite resource was expended to generate the energy in question

Ya...I don't think that many people, especially the environmentalists, think "hydro" when someone mentions renewable. Not that it isn't but the term has been hijacked by Wind and Solar mostly with a smattering of tide, wave, etc. technologies.
