The Scottish Future Trust's spotlight on street lighting highlights the transition from candles to gas, then electricity, and finally LEDs. The report states that 900,000 street lights were originally installed, which cost councils $41 million. The release of street lighting states that the use of electricity in Scotland generates 200,000 tons of CO2 into the atmosphere each year. The report also mentions that the FTSSTREETLIGHTINGINSTALLINGLEDS300MTOOLKIT has been produced to help reduce energy consumption by 50% and that Scotland's councils have invested $1.2 billion to capture the economic and environmental benefits of LED street lighting. The report concludes that over half of Scotland's street lights have been converted to LEDs, saving over $10 million a year in electricity costs alone.
