Expensive and unreliable electricity continues to weigh down Cambodia’s ranking on the UN-accredited World Energy Council’s annual Energy Trilemma Index, according to a report released yesterday. The Kingdom ranked a low 115 out of 130 countries on the annual index, which assesses countries according to how well they manage the trade-offs between three competing dimensions of energy policy: energy security, energy equity and environmental sustainability. The index reflects the challenges that countries face in developing a sustainable energy policy, with balance scores given as letter grades. An A grade and low ranking is given to top performers, while a D grade and high ranking is assigned to poor performers. Cambodia maintained its sub-par CDD balance score on the 2015 index, seeing last year’s gain in energy security – a measure of a country’s ability to meet its current and projected energy demand – reversed to rank 121st overall. The Kingdom’s rank in energy equity – a measure of the accessibility and affordability of energy across the population – edged down to 116th. It also lost ground and ranked 70th on environmental sustainability, which scores the use of renewable or low-carbon forms of energy.
