We ave. 244 Quads/yr consumption for this time period for a total of 6100 Quads!! That leaves enough to get to 2029 if we could keep the use at 244 Quads/yr.

20. UNIVERSITY OF FLORIDA 20 Gains from efficiency & renewables Source: ACEEE 2007 The Bottom Line 45% of Florida’s electric power can be met by efficiency savings and renewables by 2023. Florida generates 0.1% from renewables; national average = 2.3%. Savings in electricity costs over 15 years could total $84 billion.
