Meeting the targets

High renewable penetration

Electrification of transport and heat

Reduction of energy use

Energy efficiency improvement

Possible problems

Huge stress on networks

Significant generation assets degradation

Technologies not there and/or expensive

Lack of policies for sound business cases
