Hi Claire I need a clarification on these 2 issues.
1. My question is how come the hydroelectricity consumption which has been reported as 230.4 MTOE (million tons oil equivalent) became 616.9 MTOE. Your response is that BP has applied thermal equivalence of 38 % which means that 230 * 100 / 38 gives the equivalent of nearly 616.9 MTOE. Is this correct. It will be better if everything (oil, gas & coal) are also reported in TWH, since we know exactly the energy of 1 TWH. On the other hand 1 MTOE will be different for various grades of oil. Also finding the oil equivalent of coal & oil is even more complicated. 2. My 2nd question is "In the 'Approximate conversion factors' sheet, can you please specify the mass (weight) of 1 kiloliter of LNG. " Your table has given the mass of only Natural gas (in gaseous form), but not the mass of LNG (liquified natural gas) 1 billion cubic metres NG = 0.73 million tonnes LNG 1 billion cubic metres LNG = ???? million tonnes LNG Can you please respond. I appreciate the fact the BP has changed its name to Beyond Petroleum and is promoting renewable forms of energy. Thanks for your earlier response.
