중미 코스타리카, 올해부터 전기 생산 100% 재생 가능 에너지로.

   
The Other 98% Costa Rica got 100 percent of its energy from renewables so far this year. Share because all countries should follow their lead!     http://bit.ly/18ObtuW

뱀발) 부모가 코스타리카 출신인 미국인 영어 교사를 동네 공원에서 만나 대화하던 중, 한국 사람들이 코스타리카를 몰라서 속상하다고 함. 코스타리카와는 거의 매년 축구 국가대표 A 매치 하더만, 어떤 연줄로 계속 상대하는 것인지 혹시 아시는 분?

장면 2,

코스타리카는 올해 초부터 전력 생산을 100% 재생가능 에너지에 의존( 3월 24일 기사)

국영 코스타리카 전기 회사에 의하면, 올해 들어 전력 생산용 화석 연료를 전혀 태우지 않았다함. (자동차 연료 용도의 석유 수입은 있음)

우기에는 소수력 발전을 이용하고, 풍력, 태양력, 바이오, 그리고 지열 발전으로 서로 보완해서 어느 한 쪽에 너무 치우치지 않게 할 예정. 코스타리카의 가정 전기 공급율은 99.4%이고, 전기 요율은 오히려 12% 감소. 게다가 감소 추세가 더 이어질 것이라 함.

현재 가장 많은 연구 투자가 이뤄지고 있는 분야는 지열 발전으로 작년에 $958 million(9천 6백 억원)의 예산 승인이 이루어 졌음. 군사 예산을 줄여서 가능했다고...


Costa Rica Has Only Used Renewable Energy For Electricity This Year

Costa Rica deserves a huge round of applause, and perhaps even a high five, for managing to produce all of its electricity from renewables for 75 days straight. According to the state-owned Costa Rican Electricity Institute (ICE), the country hasn’t had to burn fossil fuels to supply the grid with electricity so far in 2015, a stretch that has never been previously attained by any nation. Of course, we don’t mean all of their energy has come from renewables as their vehicles, for example, still use fossil fuels, but what they have achieved is extremely laudable.

“The year 2015 has been one of electricity totally friendly to the environment for Costa Rica,” the ICE said in a statement last week.

As reported by Think Progress, the country’s clean streak is predominantly attributable to heavy rains experienced this year, which have kept four of the main hydroelectric power stations busy. In fact, these have been churning out so much energy that virtually all of 2015’s electricity demands have been met through these plants, according to Quartz. The remainder of the country’s grid requirements have been met through a combination of wind, solar, biomass and geothermal energy.

In Latin America, Costa Rica ranks second in terms of electricity service provision (behind Uruguay) with a household coverage rate of 99.4%. And thanks to this boon in renewables, citizens are shortly due a 12% drop in electricity rates this year and given the reserves so far accumulated, this downward trend is predicted to continue in the second quarter, Latin American Herald Tribune reports.

Costa Rica is determined to become carbon-neutral by 2021, which seems an achievable goal given that the country is currently meeting around 94% of its energy needs from renewables. Around 68% is sourced from hydroelectric power plants, followed by geothermal energy that contributes about 15%. This dedication to clean energy combined with the country’s broader environmental policies has meant that Costa Rica has been consistently ranked in the top five eco-friendly countries worldwide, according to The Telegraph.

Although what Costa Rica is achieving is something to aspire towards, it won’t be easy for many countries to follow in their footsteps. The tropical country is adorned with a string of active volcanoes that allow for geothermal projects, such as the $958 million endeavor approved last year. Costa Rica also experiences high rainfall and features a mountainous landscape, both of which are ideal for the generation of renewable energy. Furthermore, the country is able to invest substantial amounts into environmental issues due to the fact that it ditched its military back in 1948.

While Costa Rica’s dependence on renewables is commendable, it also has its drawbacks and leaves the country vulnerable to the effects of climate change. A drought, for example, would impede their ability to produce electricity from hydropower stations. Furthermore, hydroelectric dams can have negative effects on fish populations.  

Costa Rica is, of course, not the only country dedicated to going green. The EU has set renewable energy goals for 2020, but Sweden, Bulgaria and Estonia managed to meet these eight years ahead of schedule. China is also investing a substantial amount in renewables, which has been proposed to be a key factor in the fact that CO2 emissions stalled last year. Bonaire, a small Caribbean island, also currently produces almost all of its energy from renewable sources.
