joule

 (J) [jo̳l]
the SI unit of energy, being the work done by a force of 1 newton acting over a distance of 1 meter.

Joule

(jūl),
James P., British physicist, 1818-1889. See: joule, Joule equivalent.

joule (J),

(jūl),
A unit of energy; the heat generated, or energy expended, by an ampere flowing through an ohm for 1 sec; equal to 107 ergs and to a newton-meter. It is an approved multiple of the SI fundamental unit of energy, the erg, and is intended to replace the calorie (4.184 J).
Synonym(s): unit of heat (3)

joule

A unit of work, energy and heat. A watt-second. The joule is being used increasingly to replace the CALORIE in nutritional contexts. The calorie is equal to 4.187 J. (James Prescott Joule, 1818–89, English physicist).

joule

an SI unit of energy equal to 107 ergs or 0.239 cals. Named after the physicist J.P. Joule (1818–89) who determined the mechanical equivalent of heat and showed that 4.2×107 ergs = 1 calorie (4.2 joules = 1 cal.).

At the same time, production of ethanol increased to 1.6 exajoules (76 billion litres) and biodiesel to 0.6 exajoules (17 billion litres).
Under business as usual, model projections show global primary energy use more than doubling by 2100, from around 480 exajoules in 2010 to 1,100 EJ by 2100.
Bhanu Prakash, Chief Financial Officer & Director, Choice Solutions Ltd informed that the total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year.
Every year, solar radiation delivers more than 10,000 times the amount of energy contained in the electricity consumed globally every year: nearly 57 exajoules. The ability to harness a larger portion of that radiation will be crucial in the coming years, and will depend not just on revolutionary solar cell designs, but also on the creation of breakthrough nanomaterials.
If the target were the amount of energy needed to provide nine billion people with the per capita consumption that Australians are likely to have risen to by 2050 then, given the anticipated growth rate, the target is 9 billion x circa 200 giga-joules (GJ) x 2, that is, 3,600 exajoules (EJ)--an EJ is equivalent to the energy content of approximately 42 million tonnes of coal.
A 1980 report (USDA 1980) estimated the unused wood available annually for energy in the United States as equivalent to 544 million metric dry tons (600 million dry tons) or 10.8 exajoules (10.2 Quads) of energy.
