A joule is the amount of energy used to lift a small apple one meter
An exajoule is a billion billion joules
The Sun delivers nearly four million exajoules to our Earth each year
And all the worlds’ plants capture only three thousand of those
While we humans consume a paltry five hundred
in all our activities and industries
Which is equal to the amount of energy our planet receives
from the Sun in just ninety minutes
