Energy Technology cost comparisons

LCOE (Lifetime Cost of Electricity)

APGT & BREE find solar and wind much cheaper than nuclear in 2030



Bureau of Resource and Energy Economics revises costs of solar and wind down, nuclear and CCS up
(The "Technology" tag should read "Solar PV - single axis tracking technology")

Coal with CCS ? ? ?

Notes: (a) Results for RE technologies vary sensitively with location. PV in Northern Europe is more like 3 years.
(b) Some of the above results are contested in the scholarly literature on the basis of method.
