Coal has an energy value of 24 Megajoules/kg, which is the same as 6.67 kwh/kg. However a coal fired power plant will only have an efficiency of about 30 per cent so this reduces to 2.0 kwh/kg.Now when you say 1 ton, do you mean 2240 lb, 2000 lb, or 1000 kg (metric ton) ? I will assume 1000kg as it makes the arithmetic easier, in fact 2.0 kwh/kg comes to 2000 kwh/metric ton. Note that kilowatt is a power, kilowatthour (kwh) is an amount of energy, which is what you wanted.If you want it for a short ton of 2000 lb, this will become 1814 kwh, and for a ton of 2240 lb it will be 2032 kwh
1 kwh = 3,600,000 Joules
1 mwh = 1000 kwh hence 4 mwh = 4000 kwh
1 Ton of Refrigeration (US) = 3024 kcal = 3.516 KWH
1 PJ equals 277 777 777.78 kWh
Hi I believe it is 277.7 kWh per Gj. Cheers
A 1000 watt device operated continusouly for 1 hour would equal 1 Kwh.
0.001167 kWh/°C/l at 100% efficiency.

1 ton=1 ton
If you have a device of 1 KW, if this device work during an hour, this device will consume 1 KWH. If the device works during 15 min, it will consume 1KW(15 min/60 min)= 1(1/4)= .25 KWH. That is you will obtain(get?) KWH on the following way: KWH = time in hours X KW
It takes about 4.4 tons of bauxite ore (and about 14000 KWH of electricity) to produce 1 ton of aluminum.
