Renewable Energy – energy that comes from natural sources that are constantly replenished (such as sunlight, wind, rain, tides, waves, and geothermal heat) – is on a trajectory to disrupt the global energy sector. The falling cost of renewables (and energy storage), coupled with government subsidies and tougher environmental policies, is leading to a transition from hydrocarbon dependence, toward greater reliance on cleaner energy sources. The continuing long-term trend points to a steady decline in renewable energy costs and parallel increases in efficiency over the coming decade, particularly for wind and solar. This is a trend that should eventually take renewable energy costs below that fossil fuels and thus negate the need for costly government green energy subsidies and regulatory oversight.
