This page contains diverse notes related to Hawaii energy policy. Some material and analysis may be dated or sources not noted.

Information on public pages such as Resolution: Self paying vehicle loans/notes are reviewed more regularly.

Autos

 * 67.2K autos in 2006, 59.7K in 2007
 * Assuming Plug in hybrids equivalent to 30MPG vehicles, and 2.2 national average gallons per day per vehicle, the required recharge would be 15.84 KWHs per day. If half of all sales were hybrids, this would require 475 MW of power.  (New car sales in 2007 was 59.7K)

Electricity Rates

 * 20.06 cents/KWH Oahu Residential
 * 31.03 cents/KWH Hawaii Island Residential
 * 27.67 cents/KWH Maui
 * 33.95 cents/KWH Molokai

Consumption

 * 2005 gasoline use was 290 million gallons (oahu), 75M (Hawaii), 28M Kuaii, 62M Mauii County (includes Molokai & Lanai)
 * In 2005 there were 715,000 registered vehicles on Oahu, 160K maui, 169K big island, 76K Kuaii, total number of vehicles registered in Hawaii was 1,120K. This means that Oahu has 64% of the cars, consuming the 290 million gallons of gasoline, so 406 average gallons of gas is used per year per vehicle costing $1541 at $3.80 per gallon.  Assuming alternative energy recieves a guaranteed rate of 25 cents per KWH (as of April 2008 the cost per KWH for industrial solar is $0.21/KWH ), then Automotive Lithium Ion batteries necessary to drive the average distance per Oahu vehicle at a cost of $1 per watt will be paid off in 9 years.  Bob Lutz, VP of electric vehicles states that the cost per watt-hour of battery capacity in the Chevy Volt will be 63 cents per watt, and that the battery will have a 10 year life.  Such a battery would be paid off in 5.6 years.
