Costa Rica Powers 285 Days of 2015 With 100% Renewable Energy

In March, EcoWatch reported that Costa Rica powered the first 82 days of the year solely with renewable energy. Now that we're closing in on the end of the year, the Costa Rican Electricity Institute (ICE) announced that the country ran entirely on renewables for 285 days between Jan. 1 and Dec. 17.

“We close 2015 with 99 percent clean energy!” ICE wrote on Facebook, saying 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.

The majority of the country's energy (75 percent) comes from hydropower, thanks to a vast river system and abundant rainfall, and the rest of its renewables come from geothermal, biomass, wind and solar. Despite a very dry year, ICE said it was ahead of its renewable energy targets and Pacheco predicted that 2016 would be an even better year because a new $2.3 billion hydroelectric plant will be coming online.

The country reportedly wants to move away from its dependency on hydropower, though, and harness more of its electricity needs from geothermal and wind. It plans to retire its heavy fuel oil-powered Moin plant in 2017 and wants to move its transportation sector away from fossil fuels. The country has made all this progress, while reducing overall energy costs, which fell by 12 percent this year and the ICE expects costs to keep falling.

"The government has pledged to build an electric train which will be integrated with public buses," Gabriel Goldschmidt, regional head of infrastructure for Latin America and Caribbean at the International Finance Corporation, which is part of the World Bank, told the Huffington Post. "There is also a proposal to start replacing oil-powered cars with electric cars as part of a new bill in congress that aims to offer consumer incentives to lower the prices of these cars. This would have multiple benefits including better air quality."

Costa Rica's heavy reliance on hydropower has been criticized by some. Gary Wockner of Save the Colorado argues 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.

Still, the country is among the vanguard of nations around the world moving towards a 100 percent renewable energy future. Several countries have hit impressive benchmarks for renewables in just a few short years. And many places have already made the transition to fossil-fuel-free electricity. Samso in Denmark became the world’s first island to go all in on renewables several years ago. Most recently, Uruguaythree U.S. citiesBurlington, Vermont; Aspen, Colorado; and Greensburg, Kansas—along with Kodiak Island, Alaska, have all made the transition.

San DiegoVancouverLas Vegas and other major cities around the world have pledged to go 100 percent renewable. Sweden made headlines earlier this year when it pledged to be among the first countries to go fossil free. Hawaii pledged to do so by 2045—the most ambitious standard set by a U.S. state thus far. Several other islands, including Aruba, Belize, St. Lucia, Grenada, the British Virgin Islands, the Bahamas, Turks and Caicos, and San Andres and Providencia have pledged to go 100 percent renewable, through the Ten Island Challenge, created by Richard Branson’s climate group the Carbon War Room.

Greenpeace and researchers at Stanford and UC Berkeley have laid out plans for every state in the U.S. to adopt 100 percent renewables and a Greenpeace report published in September posits the world can achieve 100 percent renewable energy by 2050. Mark Jacobson, one of the researchers from Stanford, said the barriers to 100 percent clean energy are social and political, not technical or economic.

Just last week, Tesla CEO Elon Musk said in an interview that "You could take a corner of Utah or Nevada and power the entire United States with solar power."

And, it looks as if the Paris climate conference earlier this month helped create market certainty in renewables, as fossil fuel stocks tumbled and renewable energy stocks soared. After the landmark Paris agreement was reached, the coal industry's European lobbying association feared that the deal meant the sector “will be hated and vilified, in the same way that slave traders were once hated and vilified."

Slaughter of 90,000 Wild Horses Could Proceed Despite 80% Objection From American Public

The American Wild Horse Campaign on Thursday harshly criticized Interior Sec. Ryan Zinke's appointment of Brian Steed, the former chief of staff for U.S. Rep. Chris Stewart (R-UT), as the acting director of the Bureau of Land Management (BLM) as dangerous and out of step with the wishes of the vast majority of Americans.

"Rep. Stewart is leading the charge to slaughter America's wild horses and burros over the opposition of 80 percent of Americans," said Suzanne Roy, AWHC Executive Director. "Putting his deputy at the helm of the agency charged with protecting these national icons is like putting the wolf in charge of the chicken coop."

Bright Idea: This Lamp Harvests Its Own Energy From Plants

Now that's green energy. Dutch product designer Ermi van Oers and her team are working on the first atmospheric lamp powered by living plants.

The Living Light does not require an electric socket. It can harvest its own energy through the photosynthetic process of the encased plant, which means the potential of this off-grid light source could be "huge," as Van Oers told Dezeen.

Pope Francis: These 4 'Perverse Attitudes' Could Push Earth to Its Brink

Pope Francis issued a strong message to negotiators at the COP23 climate talks in Bonn, Germany on Thursday, warning them not to fall into "four perverse attitudes" regarding the future of the planet—"denial, indifference, resignation and trust in inadequate solutions."

Francis, who has long pressed for strong climate action and wrote his 2015 encyclical on the environment, renewed his "urgent call" for renewed dialogue "on how we are building the future of the planet."

Groups Sue Norway Over Failure to Protect Environment for Future Generations

By David Leestma

Greenpeace and the Nature and Youth environmental group opened a lawsuit this week over Norway's failure to abide by its constitutional obligation to safeguard the environment for future generations.

The lawsuit, which focuses on local environmental damage and the contribution that oil extraction will make to climate change, challenges 10 licenses issued by the Norwegian government for exploration in the Barents Sea. Given to Statoil, Chevron and other oil companies, the licenses violate Norway's constitution and the Paris agreement, according to the plaintiffs. Government lawyers claim the case is a publicity stunt that risks valuable jobs.

A Plea for Kelp: These Farmers and Chefs Want to Make Seaweed the Next Superfood

By Sarah Bedolfe

Summer in southeast Alaska is kelp season for the cofounders of Barnacle Foods, Lia Heifetz and Matt Kern. Each week, the pair watches the tides and weather, waiting for the right moment to cruise out to the abundant kelp beds offshore. They lean over the side of the boat and pull up the fronds and stalks, one piece at a time. As soon as they get back to shore, they start processing the day's harvest into a local delicacy: kelp salsa.

Salsa and Alaskan algae might seem like odd bedfellows, but for Barnacle Foods, it's a calculated decision. The kelp's savory notes make the salsa's flavor "a little more explosive," according to Kern. And the pairing is also a practical one. "Salsa is such a familiar food item," Heifetz said. It's "a gateway to getting more people to eat seaweed."

The leak, the largest spill to date in South Dakota, comes just days before Nebraska regulators decide on whether its controversial sister project—the Keystone XL (KXL) Pipeline—will go forward.
