Plates at our planet s surface move because of the intense heat in the Earth s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
PG&E on Wednesday did not offer a specific figure for how much the switch to renewable power would boost electricity rates in 2015. But in the past, the utility has said that rates will rise 1 percent to 2 percent each year as a result.
Because the higher decommissioning cost will be spread among all PG&E ratepayers, the increase will barely be noticeable. According to PG&E, effective Jan. 1, 2017, the bill for a typical residential customer using 500 kilowatt hours a month will go to $97.65, from $97.14 â less than a 1 percent increase.
