On the profitability of renewable energy facilities, what if equipment last less than expected?

When investments are concentrated in an industry where there is an accelerate rate of improving in operating and investment cost through technical innovations, as typically happens in renewable production energies, a process may exist where the economic life of the equipment may shorten due to the anticipated renewal process when new alternatives become competitive. In order to describe this phenomenon, a broad review is made to energy producing costs both from a descriptive approach and from the evolutionary economics perspective.
