The establishment of renewable energy aims to support sustainable energy future, including towards low environmental footprint. This study assesses the effect of an increasing share of renewable energy associated with growing energy demand in environmental performance. The environmental sustainability is quantified by the GHG, SO2, NOx emission and water consumption expressed as eco-cost. The eco-cost of the global, EU and Russian Federation performance in 2009 and 2019 are compared. The energy consumption in term of eco-cost of the world (2.06 x 10^12 EUR in 2019) and the Russian Federation (7.15 x 10^10 EUR in 2019) shows an increasing trend (+ 23.5 % and + 9.5%) despite the share of renewable energy is increased. On the other hand, Europe was decreased by 2.05 x 10^11 EUR in 2009 and 1.65 x 10^11 EUR in 2019. It is progressing towards environmental footprint reduction, contributed by the marginal increase in energy demand (+ 0.4 %) and an increase in renewable energy share. This study suggests a significant reduction (≥ ~38 % - 52 %) on nonrenewable energy dependency is required to meet the global demand in 2050 (+ 50 % of in 2008) without a substantial increase in eco-cost to that of 2009 and 2019. Alternatively, energy efficiency needs to be increase accompanies by the reduction in energy consumption.
