Jack how much does California pay for a watt or Kwt of power, and how many watts does it take to charge one 18 wheeler? They pay roughly $1.00 per Gallon more then S. Carolina, that is not in the favor of Electric. CLNE announced. $1.00 RNG for a Year in that area, they cannot charge the batteries for that..There is movement on both sides and WPRT is in a great Place... Good day...
