A total of 164 countries have adopted at least one type of renewable energy target, up from just 43 countries in 2005, according to the Renewable Energy Target Setting which was launched on the sidelines of IRENA's ninth Council meeting.
"Renewable energy targets have emerged as a popular mechanism to set national and regional economies on the path towards a more secure and sustainable energy future. They provide an important signal to the industry and can help align stakeholders by creating a clearer, common vision for the development of the energy sector," IRENA Director-General Adnan Z Amin said yesterday.
The majority of countries focus on the electricity sector - 150 countries has renewable electricity targets - but commitments in other sectors are also on the rise.
The number of countries setting targets for the heating/cooling sector increased from two countries in 2005 to 47 today. Similarly, renewable transport targets have more than doubled from 27 countries in 2005 to 59 today.
In order to be seen as credible by investors and society and to provide a reliable trajectory for the future evolution of the energy mix, renewable energy targets need to be accompanied by a clear strategy and backed by specific policies and measures, the report added.
