A stunning ‘hockey stick’ – How access to energy brought humanity forward


Anthony Watts, proprietor of WUWT has posted “A stunning ‘hockey stick’ – How access to energy brought humanity forward”. The charts show the dramatic reduction in global poverty since the invention and use of the steam engine. Fossil fuels have “powered” this improvement in the human condition. I am reblogging Watts’ posting.

Watts Up With That?

People send me stuff.

I got an email today that contained a blog post about another subject unrelated to climate or energy, but it had this graph in it that caught my eye:

global-gdp-since-steam-engine

The invention of the steam engine (which used coal and wood at first, with oil and natural gas coming later) seems to be the catalyst for change in the human race. Now that’s a hockey stick we can all get behind!

Wikipedia has a similar graph:

World_GDP_per_capita_1500_to_2003

Data extracted from Angus Maddison’s “World Population, GDP and Per Capita GDP, 1-2003 AD

And then there’s this one, going all the way back to 500 B.C.
