this stabilization has in part been attributed to increased penetration of renewable energy and to improvements in energy efficiency both of which have experienced dramatic acceleration in recent years global demand for renewables has steadily increased as has energy consumption particularly in developing countries global installed capacity and production from all renewable energy technologies have likewise increased as most have seen significant cost reductions worldwide and have reached parity in some markets global energy intensity has consequently decreased at a compounded annual rate averaging about per cent between and and most world regions achieved improvements in aggregated energy intensity during this period
