+ \hline
+ Energy source & Energy content & Renewability & Environmental impacts of extraction & Environmental impacts of combustion & Key combustion equation/s \\ \hline
+ Coal (brown/black) & Low (black: 34 kJ/g, brown: 16 kJ/g) & Very low - produced by fossilised plant material (thousands of years) & Destruction of vegetation, pollution due to mine waste (tailings etc), greenhouse emmissions from transport \& mining machinery & Acid rain (\ce{SO2}), greenhouse gas emmission & \\ \hline
+ Crude oil & & & Transport by road \& sea releases greenhouse gases.
+ & Toxic \ce{CO} with incomplete combustion, & Complete: \ce{2C16H34(l) + 49O2(g) -> 32CO2(g) + 34H2O(g)} Incomplete: \ce{2C16H34(l) + 17O2(g) -> 32C(s) + 34H2O(g)} \\ \hline
+ Petroleum gas & 48 kJ/g & Refinement causes hydrocarbon pollution of air. & & Uncombusted hydrocarbons may be released (\ce{CO}), causing photochemical smog.
+ & Complete: \hspace{2em} \ce{2C8H18(l) + 25O2(g) -> 16CO2(g) + 18H2O(g)} Incomplete: \ce{2C8H18(l) + 17O2(g) -> 16CO(g) + 18H2O(g)}\\ \hline
+ Coal seam gas & $\approx$ 54 kJ/g (nat. gas)& & Destruction of vegetation \& geology (drilling), pollution of aquifers & Greenhouse gas emmissions & Methane: \hspace{4em}\ce{CH4(g) + 2O2(g) -> CO2(g) + 2H2O(g)} \\ \hline
+ Biogas & Relatively inefficient & & & & \\ \hline
+ Bioethanol & & & & & \\ \hline
+ Biodiesel & & Very renewable – sourced from used cooking oil, tallow, oil seed crops & Consumption of waste (landfill reduction). Less space for agriculture \& forests. Biodegradable. Byproducts (glycerol) can be used elsewhere. & & \begin{align*}\ce{\\C17H29COOCH3(l) + 26O2(g)\\ -> 19CO2(g) + 16H2O(g)}\end{align*} \\ \hline
