Renewable energy growth must speed up to meet Paris goals, agency says

International Renewable Energy Agency says $131tn investment in renewables could be required over three decades

Renewable electricity production needs to grow eight times faster than the current rate to help limit global heating, according to a report.

The International Renewable Energy Agency (Irena) said urgent action was needed to keep pace with rising demand for electricity, which could require a total investment of $131tn in renewables by 2050.
