Why are regions where convection currents diverge more suitable for building geothermal power stations

The two diverging convention currents bring up the heat from deep below the mantle. They act like two cogs/pulleys that complement each other to bring up very hot asthenospheric materials. Where a divergent boundary occurs, there also occurs a rift such as the Great Rift Valley in East Africa.  

because the light is a great source of energy for the plants to survive. (i hope this )
