The analysts have projected that by 2020, renewables will be the cheapest form of new-power generation across the globe, with the exception of a few countries in Southeast Asia. According to their forecasts, favorable renewables economics rather than government policy will be the primary driver of changes to utilities' carbon emission levels. Therefore, notwithstanding President Trump's stated intention to withdraw the US from the Paris climate accord, they expect the US to exceed the Paris commitment of a 26-28% reduction in its 2005-level carbon emissions by 2020.
On a global level, the price of solar panels has fallen by 50% between 2016 and 2017. In countries with favorable wind conditions, the costs attributed to wind power can be as low as one-half to one-third that of coal or natural gas-fired power plants. Furthermore, innovations in wind-turbine design are allowing for even longer wind blades, boosting their efficiency and thus increasing power output from the wind sector.
