Kakade ngo-Okthoba besiphawula ukuthi iningi logesi lelo kudla iCosta Rica livela emandleni avuselelekayo. Zonke izindaba ezimnandi ezijoyina enye efike ekuqaleni kwale nyanga lapho i- protagonist yi-Uruguay nge amaphesenti amakhulu kagesi atholakele kusuka kule mithombo yamandla ehlanzekile futhi esimeme.
ICosta Rica iyi- izwe elincane elinabantu abangaphansi kwezigidi ezi-5. Muva nje ikhiphe isitatimende lapho ibikhombisa khona ukuthi bekuyizinsuku ezingama-285 ithola kanjani ugesi wayo u-100% kulezi zinto ezivuselelekayo. Manje, iCosta Rican Electricity Institute yethule enye lapho ithi khona u-99% wawo wonke ugesi otholakele uvela kulolu hlobo lomthombo ngonyaka ka-2015. Osekusele, u-1%, kwakusuka kwizibaseli.
Uhulumeni waseCosta Rican umemezele ngoMashi ukuthi izwe belikhona iya ngqo kumandla avuselelekayo okokuqala ezinsukwini ezingama-75 kulo nyaka. Kubuye kwabeka nomgomo wokufinyelela amaphesenti angama-97,1 emithonjeni ye-geothermal, umoya, i-biomass kanye nemithombo yamandla elanga unyaka wonke.
Lokhu sekube yi- umjaho wokulwa nesikhathi samazwe amaningi kusetshenziswa okuvuselelekayo ngokugcwele. I-Uruguay ingelinye lalawo mazwe akhiqiza u-95% kagesi wawo emithonjeni yamandla ehlanzekile. I-Iceland nayo ibheke indlela yokufeza okufanayo, kanti iDenmark muva nje ikhiqize iningi lamaphesenti ayi-140% kagesi wayo odinga imishini yomoya.
Ngenxa yala mazwe singasho ukuthi kuvula indlela yokuthi abaningi bayijoyine ukuze bathi bafinyelela cishe ku-100% wamandla avuselelekayo. Yize amazwe athile, esebenzisa ugesi ophakeme kunabo bonke emhlabeni, njenge-United States, kungathatha iminyaka engama-35 ngokwazi ukuthola u-80% kagesi wayo kule mithombo.
