A trajectory towards 100%
renewable generation is feasible,
and the technical challenges
associated with this
transformation can be met in a
way that is affordable for
consumers.
Connection of large-scale renewable generation in areas with abundant renewable resources could
be enabled by extension of the transmission network to those areas.
The transition to large-scale renewable sources of energy will
be enabled by transmission
