The dearth in native gas production is partly caused by the Marathon gas field winding down and a new one off Mayo not being on stream yet.  As we have very little native Coal and declining peat resources, they're not an ideal base load sources.   Virtually all new capacity is coming from wind, with some R&D into wave energy. Provience has claimed significant Oil resources off the south Dublin coast - prompting some wags to proclaim that Northersiders are being discriminated against again.
