How much energy can we extract from sunlight per square meter by growing wood? Assume: Short rotation coppices produce 10 tons of wood per hectare (10,000 m^2) per year. Dry wood has a calorific value of 18 MJ/kg.
Added by Tamara F.
Step 1
- 10 tons of wood per hectare per year is equivalent to 10,000 kg of wood per hectare per year. - Calorific value of dry wood is 18 MJ/kg. - Therefore, the total energy content of the wood produced per hectare per year is 10,000 kg * 18 MJ/kg = 180,000 MJ per Show more…

Look up the energy you get by chemical combustion (burning wood, etc. - just take a typical number in J/kg), and estimate how long you can power the Sun that way. Where energy is 9.3 x 10^6 J/kg

The sun supplies energy at a rate of about 1.0 kilowatt per square meter of surface area (1 watt = 1 J/s). The plants in an agricultural field produce the equivalent of 20 kg of sucrose (C12H22O11) per hour per hectare (1 ha = 10,000 m2). Assuming that sucrose is produced by the reaction 12CO2(g) + 11H2O(l) → C12H22O11(s) + 12O2(g) ΔH = 5640 kJ Calculate the percentage of sunlight used to produce the sucrose—that is, determine the efficiency of photosynthesis.
