76 Days, No Fossil Fuels: Costa Rica Has Been Running On Renewables For Over Two Months

by Don Galeon: This island is leading the way in renewable energy…


Not The First Time

Last year, Costa Rica powered itself purely with renewable energy for 299 days total. This year, they already hit a total of 150 days — and counting!

It was last 16 June 2016 when the government said goodbye to fossil fuels (again), according to the National Center for Energy Control (CENCE). Since then, the country ran on 100 percent renewable energy for 76 days.

Costa Rica deserves a clean (or green) bill of health! This Latin American country has proven, yet again, that it is possible to run on a mix of various sources of renewable energy.

Bulking Up On Renewables

Of course, the country’s relatively small size helped, with the seasonal heavy rainfalls. But so did the four hydroelectric power facilities, which accounted for 80.27 % of the country’s total electricity last August. Geothermal plants that contributed roughly 12.62 %. Plus the wind turbines, with 7.1 %. Not to mention good ol’sunshine lending a hand with 0.01 %.

While it can be said that Costa Rica’s situation contributed to the ease with which the country transitions from fossil fuels to clean renewable energy, it did not lack in the effort and infrastructure to further the cause.

In fact, the Latin American country is geared to pump up more renewable energy. A massive hydroelectric power plant is about to be completed — a project called Revantazón, under the Costa Rica Electricity Institute (ICE). Zach Dyer of The Tico Times reports that, with five turbines being built, the Revantazón project “will have a generating capacity of 305.5 MW, enough for an estimated 525,000 homes.”

It is the largest hydroelectric project in the region since the Panama Canal.

A Lack Of Evidence

Some people swear by antibacterial soap. They won’t even consider washing their hands with just regular old soap and water.

In a recent FDA press release, Janet Woodcock, director of the FDA’s Center for Drug Evaluation and Research voiced her concern over this preference:

“Consumers may think antibacterial washes are more effective at preventing the spread of germs, but we have no scientific evidence that they are any better than plain soap and water.”

In a study, published in the Journal of Antimicrobial Chemotherapy in September 2015, researchers compared antibacterial soap with regular soap. The experiment exposed individuals to bacteria that weakens the immune system, and had them wash their hands with antibacterial soap and regular soap. The results were practically the same.

Essentially, there isn’t enough Triclosan in antibacterial soap to kill all of the germs on your hands each time you wash them. At these low concentrations, the chemical instead exerts selective pressure on bacteria, allowing them to quickly evolve, resulting in bacterial resistance and superbugs.

In the end, everybody can rest easy. Even with the ban of antibacterial soap, we can still have clean hands.
