The primary energy resources (production and import) and electricity resources dropped by 3.8% and 5.9% respectively in the first quarter of 2007, compared to the same period last year, the National Statistics Institute says in a press release on Monday.

The release says the main primary energy resources - coal, crude and natural gas - totaled 10.5 million tons in oil equivalent, down 409,000 tons compared to Q1 2006. The trend was caused by domestic production (down 6.7%) and a 0.6% boost of imports.

The steepest decrease was reported in natural gas production (-16.5%), while crude production grew 0.5%.

Electricity resources stood at 16.41 billion KWh, down 5.9% compared to the same period last year mainly due to a production diminished by 849.8 million KWh and imports down by 188.6 million KWh.
