2034 peak on mass basis
2026 peak on energy basis
Net energy is important
But it can be done!
More optimistically...
“Conclusions” - for discussion
• (How) Can we reduce at required rate without economic crisis?
• (How) Can we reduce to required level without economic hardship?
• (How) Can the world’s people be made to accept rapid change?
• What other physical and thermodynamic limits are we close to?
• Why was energy not discussed in Copenhagen?
