directly convert solar energy into electricity using a PV cell; this is a semiconductor device.
plug-in hybrid electric vehicle
contains both an internalcombustion engine and a motor with battery pack. In contrast, a regular hybrid vehicle does not have enough battery storage on board to make worthwhile the addition of plug-in capability. PHEVs tend to have a shorter electric-driving range than EVs, but conversely have the benefit of a back-up internal combustion engine should the battery get drained.
fuel use in electricity plants, heat plants and combined heat and power (CHP) plants. Both main activity producer plants and small plants that produce fuel for their own use (autoproducers) are included.
