How much natural gas/crude oil is required to generate 1 KW of electricity?

I am comparing the costs of generating electricity from crude oil and natural gas.





I would like to know:





1. How much natural gas is required to generate 1 KW of electricity?





2. How much crude oil is required to generate 1 KW of electricity?





My government just increased the electricity bills by 21% citing increasing oil futures prices as the justification to do that. However, Singapore generated about 80% of its electricity from natural gas and not crude oil! I think this is a rip off.How much natural gas/crude oil is required to generate 1 KW of electricity?
Unfortunately it's not as simple as X litres of crude oil equals Y kilowatts of energy. It depends entirely on the process in which the energy is extracted, which includes refinement, the efficiency of the turbine, the efficiency of the burning process and the efficiency of the heat transfer.





You may be able to get this information by contacting your local power supplier however they may be slightly guarded but it would be worth a try.





The rising crude oil prices are not the only cause for energy price hikes, with recently introduced emission standards/taxes a possible reason also.
