The role of renewable energy solutions in mitigating climate change is proven. The heavy reliance on fossil fuels and inefficient and outdated coal-fired power plants is one of the main reasons for the energy sector’s high contribution to global greenhouse gas emissions. This not only elevates global temperatures but seriously impacts on air quality and human health. Transitioning to renewable energies therefore supports significant progress on the Paris Agreement on climate change, as well as on the Sustainable Development Goals (SDGs).
Based on REN21's 2017 report, renewables contributed 19.3% to humans' global energy consumption and 24.5% to their generation of electricity in 2015 and 2016, respectively.
Worldwide investments in renewable technologies amounted to more than US$286 billion in 2015, with countries like China and the United States heavily investing in wind, hydro, solar and biofuels.
Total renewable energy consumption in 2016 worldwide was 16880.4 TWh, out of which modern renewable energy sources 5877.19 TWh.
165 countries has renewable energy policies and plans and over 150 countries have been working actively in this with targets to increase capacity in near future.
