Energy and capital are assumed to be complementary in the production process. New machines are less energy consuming and scrapping is endogenous. It is shown that the impact of investment subsidies heavily depends on the structure of the energy market, the mechanism explaining this outcome relying on the tight relationship between the lifetime of capital goods and energy prices via the scrapping conditions inherent to vintage models. In particular, under a free entry structure for the energy sector, investment subsidies boost investment, while the opposite result emerges under natural monopoly if increasing returns in the energy sector are not strong enough.
