Ghana has a rising trend in street lights energy consumption. A consumption that has risen from 31 GWh in 2000 to 382 GWh in 2014.

With per kWh tariff of 8.67US Cents, the energy consumption by the traditional street lights amounts to $33,119,400 USD annually. Converting all existing traditional street lights into solar street light will mean that the Ghana will save 382 GWh (3.75%) of our energy and 33M USD annually.

Globally, traditional street lighting consumes about 159 TWh of electricity annually. A reduction of consumption by 50% would eliminate around 80 TWH of electricity consumption and avoid around 40 MtCO2 per year.
