Cities increasingly recognise the benefits of sourcing power from renewables
Most directly, renewable power generation in the urban context can be done at utility scale, such as through solar PV, wind or geothermal facilities.
For example, street lights can account for as much as 40% of a city’s energy budget.
Solar lights with LED bulbs offer energy and cost savings of 50% or more in comparison to conventional lighting and have greater life span and durability.
However, of the approximately 300 million streetlights globally, only about 10% are LEDs.
