150 Days and Counting, Costa Rica Gets All of Its Electricity From Renewables

Clean power superstar Costa Rica has hit another renewable energy milestone. The Central American country's electric grid has been powered entirely by its mix of hydropower, wind, solar, geothermal and biomass for 150 days this year and counting.

Impressively, as Mashable reported, the country has not used fossil fuels for electricity for the last 76 days, from June 16 to Sept. 2, according to data from the country's power operator, Costa Rica Electricity Institute (ICE).

According to an ICE report, hydropower contributed about 80 percent of the country's electricity needs in August, followed by geothermal (12 percent), wind (7 percent) and solar energy (0.01 percent).

Costa Rica hasn't needed to rely on fossil fuels for electricity since June 16. "Since then, it's been 76 consecutive days in which all electricity has come from plants that use renewable resources," the ICE said.

"We are a small country with great goals!" ICE wrote on Facebook. "We remain committed to the goal of carbon neutrality for 2021."

Costa Rica is becoming well-known for its renewable energy accomplishments. Last year, the country generated nearly all of its electricity from renewables.

"We close 2015 with 99 percent clean energy!" ICE announced, adding that "the energy produced … in 2015 reaches 98.95 percent with renewable sources as of December 17."

"We are closing 2015 with renewable electricity milestones that have put us in the global spotlight," ICE electricity division chief Luis Pacheco told AFP last year.

Carlos Manuel Obregón, the executive president of ICE, said Costa Rica will soon switch on its massive Reventazón hydroelectric project. The dam's five turbines will have a generating capacity of 305.5 megawatts, or enough power for an estimated 525,000 homes, according to The Tico Times.

As EcoWatch previously mentioned, the majority of the country's energy comes from hydropower, thanks to a vast river system and abundant rainfall. Hydropower, however, is not without its faults.

Gary Wockner of Save the Colorado argued that hydropower is actually "one of the biggest environmental problems our planet faces" and a "false solution" for addressing climate change.

"Hydropower has been called a 'methane factory' and 'methane bomb' that is just beginning to rear its ugly head as a major source of greenhouse gas emissions that have so-far been unaccounted for in climate change discussions and analyses," Wockner said last month.

The Guardian also noted last year that hydropower requires consistent rainfall, which means that during periods of drought, the country's utilities are all but forced to burn fuel.

Costa Rica's transportation sector is also still dependent on petroleum, and a new report from Costa Rica News indicates that the total fuel consumption is growing, with sales increasing 11 percent compared to the same period last year.

And for a small country like Costa Rica, it's simply easier to consume less.

As Mashable explained:

"This nation of 4.9 million people generated about 10,713 gigawatt-hours of electricity in 2015, according to a July report from the Economic Commission for Latin America and the Caribbean. The United States, by contrast, generated about 373 times more electricity, with roughly 4 million gigawatt-hours of total generation in 2015, according to data from the US Energy Information Administration."

Still, even with these circumstances and setbacks, Costa Rica's latest clean energy streak is something to be admired and an example for other countries to follow.

Farmers are the stewards of our planet's precious soil, one of the least understood and untapped defenses against climate change. Because of its massive potential to store carbon and foundational role in growing our food supply, soil makes farming a solution for both climate change and food security.

The vast majority of SARS-CoV-2 transmission occurs indoors, most of it from the inhalation of airborne particles that contain the coronavirus. The best way to prevent the virus from spreading in a home or business would be to simply keep infected people away. But this is hard to do when an estimated 40% of cases are asymptomatic and asymptomatic people can still spread the coronavirus to others.

The tiny island nation of Mauritius, known for its turquoise waters, vibrant corals and diverse ecosystem, is in the midst of an environmental catastrophe after a Japanese cargo ship struck a reef off the country's coast two weeks ago. That ship, which is still intact, has since leaked more than 1,000 metric tons of oil into the Indian Ocean. Now, a greater threat looms, as a growing crack in the ship's hull might cause the ship to split in two and release the rest of the ship's oil into the water, NPR reported.

On Friday, Prime Minister Pravind Jugnauth declared a state of environmental emergency.

France has sent a military aircraft carrying pollution control equipment from the nearby island of Reunion to help mitigate the disaster. Additionally, Japan has sent a six-member team to assist as well, the BBC reported.

The teams are working to pump out the remaining oil from the ship, which was believed to be carrying 4,000 metric tons of fuel.

"We are expecting the worst," Mauritian Wildlife Foundation manager Jean Hugues Gardenne said on Monday, The Weather Channel reported. "The ship is showing really big, big cracks. We believe it will break into two at any time, at the maximum within two days. So much oil remains in the ship, so the disaster could become much worse. It's important to remove as much oil as possible. Helicopters are taking out the fuel little by little, ton by ton."

Sunil Dowarkasing, a former strategist for Greenpeace International and former member of parliament in Mauritius, told CNN that the ship contains three oil tanks. The one that ruptured has stopped leaking oil, giving disaster crews time to use a tanker and salvage teams to remove oil from the other two tanks before the ship splits.

By the end of Tuesday, the crew had removed over 1,000 metric tons of oil from the ship, NPR reported, leaving about 1,800 metric tons of oil and diesel, according to the company that owns the ship. So far the frantic efforts are paying off. Earlier today, a local police chief told BBC that there were still 700 metric tons aboard the ship.

The oil spill has already killed marine animals and turned the turquoise water black. It's also threatening the long-term viability of the country's coral reefs, lagoons and shoreline, NBC News reported.

"We are starting to see dead fish. We are starting to see animals like crabs covered in oil, we are starting to see seabirds covered in oil, including some which could not be rescued," said Vikash Tatayah, conservation director at Mauritius Wildlife Foundation, according to The Weather Channel.

While the Mauritian authorities have asked residents to leave the clean-up to officials, locals have organized to help.

"People have realized that they need to take things into their hands. We are here to protect our fauna and flora," environmental activist Ashok Subron said in an AFP story.

Reuters reported that sugar cane leaves, plastic bottles and human hair donated by locals are being sewn into makeshift booms.

Human hair absorbs oil, but not water, so scientists have long suggested it as a material to contain oil spills, Gizmodo reported. Mauritians are currently collecting as much human hair as possible to contribute to the booms, which consist of tubes and nets that float on the water to trap the oil.

There are trillions of microplastics in the ocean — they bob on the surface, float through the water column, and accumulate in clusters on the seafloor. With plastic being so ubiquitous, it's inevitable that marine organisms, such as sharks, will ingest them.
