Future without Nuclear Energy; is it Feasible, is it Sensible?

Considering the necessity and future role of nuclear energy as relevant to climate problem, we have focused on period year 2065. For quantification required emission reduction used IEA WEO 2009 2011 data presented in their Reference strategies predicting emissions with business usual practices, 450 Energy which show time development allowed consistent a limit global temperature increase 2 ºC peak CO2 concentration ppm. By extrapolating these 2065 obtain 77.4 GtCO2-eq for 10 strategy allowing emission, resulting 67.4 come down sustainable trajectory. The large contributions from fusion fossil fuel carbon separation storage are not likely. Main non-emitting sources assumed years up proven technology fission renewable sources. In our specified aimed achieve target an mix including power build-up 2025-2065 level 3300 GW With contribution 25.2 GtCO2 total GtCO2, what remains sources, saving increased efficiency use contribute prodigious 42.2 GtCO2-eq. Assuming that more efficient will by effect annual between 16 GtCO2-eq, remaining 26.2 32.2 respectively 27290 33540 TWh would be task Our estimates about going far based EREC prediction EU extension world GWEC guide. high, but still credible predicted similar figures 29260 36180 TWh. However, without 2065, doubled, practically impossible consideration. Resulting probably upper limits, allow some conclusions decades. combining highest saving, other measures reduce apart production, contribution, minimum requirement 2190 This should planned prepared for, unless there is strong evidence free (CCS or fusion) could developed time. Expansion 1800 different already industrial sector, can give its mix, obstructing It wise forfeit at least critical control change.
