Document Summary
How much energy you use on a personal basis how much light you use, hairdryer, public system: this is a really massive energy xi. And this energy goes up 2% / year xii. Energy in the thermohaline or wind is immense. xiii. Shows how much energy the planet can absorb: slides, shows world energy demand, units are little bit different, bit more common, kw/h - measure of energy, kw/h per annum is shown. Same as before: 120 [1012kwh/a] if you use a device which uses a 120kwh then it uses 120 kw per hour. It is easy as that: converting it to j/s we would multiply it by 1000w/kw x 3600 s/hr. get rid of the kw, and hours. J is the convention people use a lot: the graph in the slide, 120x10^12kwhr/yr (to convert it into j) 120x10^12 x 1000 w/kw x 3600 s/hr = 4x10^20ws: 4x10^20 j, prior to industrial revolution everything was biomass.
