What uncertainty ranges surround key results?
Renewable share [94.12%, 98.54%], investment [235.2B], emission reduction [87.3%, 92.8%]. PICP=95.4%, MPIW=11.8 GW.
Key Takeaway
Uncertainty: 90% CI renewable share, investment; policy robust across scenarios.
Detailed Explanation
Comprehensive uncertainty quantification establishes confidence bounds: **Renewable Share (2050):** point estimate 97.34%; confidence interval [94.12%, 98.54%] at 90% confidence level (obtained by bootstrapping across 30 independent RL training runs), indicating robustness to stochasticity in the optimization. The point estimate for total investment is 218.4B, $235.2B]. This assumes a ±3.7% variation, which incorporates technology cost uncertainty (solar/wind CAPEX ±30%), demand uncertainty (±20%) and financing cost variation (±150 bps on the interest rate). The point estimate for emission reduction is 90.6% (152 to 14.30 MtCO₂) with a likely range (90% CI) of [87.3%, 92.8%]. This uncertainty covers demand growth as well as residual fossil fuel deployment. The 95% prediction intervals from the ENSM achieve a coverage probability of 95.4% (PICP=95.4%) with an average prediction interval width (MPIW) of 11.8 GW, which corresponds to ±5.4% of the 2050 capacity. A 30% variation in solar/wind CAPEX affects the renewable share by ±2-3 pp; a 50% variation in carbon price affects it by ±1.5 pp; a 40% variation in storage/transmission CAPEX affects it by <1 pp. The policy is robust to extreme scenarios. Specifically, in the scenario of +20% demand growth, there is a 95.1% renewable share. A -30% faster reduction in technology costs would result in a 98.2% renewable share. On the contrary, a +30% slower reduction in technology costs would result in a 92.8% renewable share. A 50% deviation in the carbon price in both directions would result in a 93.1% renewable share and 98.7% renewable share.
