This work revisits an idea that dates back to the early days of scientific computing, the energy method for stability analysis. It is shown that if the scalar non-linear conservation law ∂u ∂t + ∂ ∂x f(u) = 0 is approximated by the semi-discrete conservative scheme duj dt + 1 ∆x ( fj+ 1 2 − fj− 1 2 ) = 0 then the energy of the discrete solution evolves at exactly the same rate as the energy of the true solution, provided that the numerical flux is evaluated by the formula
