Abstract: In this paper we derive a formula relating the energy and the Fourier transform of a finite measure on the $d$-dimensional torus which is similar to the well-known formula for measures on $\mathbb{R} ^{d}$.

We apply the formula to obtain estimates on the Hausdorff dimension of Riesz product measures. These give improvements on the earlier, classical results which were based on completely different techniques.
