The deployment of such energy transition might be threatened by the risks of supply of some of the key materials and technologies that are needed.
The revision of the Renewable Energy Directive sets a binding renewable energy target  to represent at least 42.5% of Europe’s energy mix by 2030. Green energy technologies — such as batteries, solar photovoltaic (PV) panels and wind turbines — are already considered key to meeting renewable energy targets. The deployment of such energy transition might be threatened by the risks of supply of some of the key materials and technologies that are needed.
