CALIFORNIA ENERGY COMMISSION Page 14 Incremental MW Impacts from Programs Begun Prior to 2001
CALIFORNIA ENERGY COMMISSION Page Crisis Executive, legislative, and regulatory responses to crisis $850 million additional funding Peak demand reduced in 2001 average of 10.4% over summer months of 2000 Consumption down 6.7% from 2000 First-year savings estimated at 4.76 million MWh and 3,389 MW from 200+ programs
CALIFORNIA ENERGY COMMISSION Page 16 Additional Potential for Energy and Peak Demand Savings? Emerging technology potential Existing technology potential Conservation behavior potential
CALIFORNIA ENERGY COMMISSION Page 17 Summary of 10-Year Net Achievable Energy Efficiency Potential
CALIFORNIA ENERGY COMMISSION Page 18 Statewide Peak Electricity Demand Scenarios +3% -3% 2.14 % 1.62% 1.88 %
CALIFORNIA ENERGY COMMISSION Page 19 Natural Gas Demand Scenarios Low DSM 0.78% growth High DSM 0.67% growth Baseline Forecast 0.73% growth +0.55% -0.70%
CALIFORNIA ENERGY COMMISSION Page 20 Findings Buildings account for two-thirds of electricity consumption and three-fourths of peak Air conditioning dominates peak load, followed by commercial lighting, the miscellaneous categories for both residential and commercial, & residential refrigeration Uncertainty factor is higher for natural gas potential Higher spending has achieved higher savings Changes in behavior were very important in 2001 Additional achievable potential remains, but may be harder to get
