An energy transformation flow diagram is shown. X is a type of energy and Y is the location where the energy transformation is taking place.

letter X followed by an arrow with letter Y written on top of the arrow and Electrical Energy written after the arrow

What do X and Y represent?

X = chemical energy; Y = wind turbine

X = chemical energy; Y = hydroelectric power plant

X = gravitational energy; Y = thermal power plant

X = gravitational energy; Y = hydroelectric power plant
