WebOn average, a ton of coal produces 21 to 22 gigajoules of energy. The amount of energy produced by a ton of coal is largely dependent upon the type of coal being burned. There are four major categories of coal, each differing in composition and age. Lignite, also known as brown coal, is the least valuable of the four. WebFor example, what mass of brown coal is required to produce 800 kJ of energy? mass of brown coal (g) = energy (kJ) ÷ heat content of brown coal (kJ g-1 ... 1 J = 1 kg.m 2 s-2 The joule is named after the English physicist James Prescott Joule. Other units for measuring energy are: calorie, cal (1 J = 0.239 cal) ... orgy\u0027s 4u

WebMultiplying by 2,000 pounds/ton, we get 714 pounds ( 325 kg) of coal. That is a pretty big pile of coal, but let's look at what else was produced to power that light bulb. A typical 500-megawatt coal power plant produces 3.5 billion kWh per year. That is enough energy for 4 million of our light bulbs to operate year round.
