Small birds like that in (Figure 1) can migrate over long
distances without feeding, storing energy mostly as fat
rather than carbohydrate. Fat is a good form of energy
storage because it provides the most energy per unit
mass: 1.00 grams of fat provides about 9.40 (food)
Calories, compared to 4.20 (food) Calories per 1.00
grams of carbohydrate. Remember that Calories
associated with food, which are always capitalized, are
not exactly the same as calories used in physics or
chemistry, even though they have the same name. More
specifically, one food Calorie is equal to 1000 calories of
mechanical work or 4184 joules. Therefore, in this
problem use the conversion factor 1 Cal = 4184 J.

Plants capture the energy when growing, and then through a long process of decay and compression this plant matter is converted into a fossil fuel. An interesting question is how much sunlight is needed to produce a quantity of petrol. To estimate this, let's assume the petrol has come from wood, and let's assume we have a fast-growing wood source such as Pinus radiata. Assume also: a mature tree contains around 3 m3 of timber; a tree is harvested when 35 years old; the density of wood is around 500 kg/m3; 2 kg of wood makes 1L of petrol; a tree receives on average 8 hours of sunlight per day. How many "hours of sunlight" are stored in 1L of petrol? i.e. how many hours of sunlight does a tree need to be exposed to, to produce the amount of wood needed to make 1 L of petrol?
