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.
The CPUC agreed with PG&E that the hike is necessary to set the revenue amount needed for PG&E to provide safe and reliable electric and natural gas service for 2014-2016.. PG&E rates for all customers will increase 4.57 percent in 2015 and 5 percent in 2016. State officials did not give PG&E everything it wanted, however, and lowered the amount requested by $700 million. PG&E had asked the state utility commission to approve rate increases of 5.9 percent for 2015 and 6.1 percent for 2016.
