This report synthesizes a host of developments in the renewables sector during the year 2016-17 covering power generation from various renewable energy technologies, advances in policy and regulatory frameworks, growth in manufacturing capacity and investment flows, and contribution of renewables to emissions reduction.

Bioenergy is the main source of renewable energy today.

As oil and coal fall back and renewables ramp up strongly, natural gas becomes the largest single fuel in the global mix in the Sustainable Development Scenario says World Energy Outlook 2017.

The rapid fall in cost of solar and wind power technologies opens a new range of possibilities to decarbonise the global economy and cut carbon emissions from industry. Besides direct renewable heat and electrification, hydrogen-rich chemicals that are easy to store and transport could serve as feedstock, process agents and fuels.
