# Energy consumption [closed]

If the yearly worldwide energy consumption is 80,000 TWh, and a particular earthquake generates 1.6x10^13 Joules of energy.

If we could harness all of the energy from the earthquake, for how long could we power the entire earth?

• Look up the conversion rate from J to kWh. Then do the maths. – hdhondt Jun 6 at 23:22
• @hdhondt I don’t understand, the question does not mention KWh, only joules and TWh. – Ubaid Hassan Jun 7 at 0:28
• KWh= kilo Watts-hour=1,000 Wh. TWh= tera Watts-hour=1,000,000,000,000 Wh. The prefixes in most quantities in physics are multiplication by some factor of 1000. – S V Jun 7 at 1:42
• You should not have to look up anything. You should understand what the relationship is between a joule and a watt-hour. – G. Smith Jun 7 at 2:10
