However, this is simply a logical fallacy. Economic growth correlates well with energy use, but there's no reason that energy has to come from fossil fuels. It's just that historically, the market price (though not the actual net cost) of fossil fuels has been very low. However, the SRREN notes that renewable energy can help decouple that correlation between economic growth and GHG emissions, contributing to sustainable development. Another key to meeting increasing energy mands from developing countries with renewable power is the rapidly decreasing cost of these technologies, particularly solar photovoltaic (Figure 2).
