To be pedantic, the lightning is actually nature's way of discharging already stored energy. The energy is already stored in a charge imbalance between the clouds and the ground (much like a battery or capacitor). You would want to find a way to use that potential energy in a helpful way, rather than letting nature 'waste' it on lightning (much in the same way that shorting an electrical circuit wastes the energy made at the power plant).
