LED Traffic Lights

I wonder if the relative costs of replacing traffic lights is considerd in savings for LEDs. I have seen three or four men with a cherry picker replacing traffic lights in Columbus. This must cost $100 per change. With many fewer changes with LEDs, this cost is drastically reduced.

I plan to write about the barriers to achieving the energy goals in Ohio SB221:

(ORC 4928.64(B)) Utilities must provide 25% of their retail electricity supply from alternative energy resources by 2025, with specific annual benchmarks for renewable and solar energy resources:

Year Renewable(%) Solar (%)

2009 0.25 0.004
2010 0.50 0.010
2011 1.0 0.030
2012 1.5 0.060
2013 2.0 0.090
2014 2.5 0.12
2015 3.5 0.15
2016 4.5 0.18
2017 5.5 0.22
2018 6.5 0.26
2019 7.5 0.30
2020 8.5 0.34
2021 9.5 0.38
2022 10.5 0.42
2023 11.5 0.46
2024+ 12.5 0.50

At least 50% of the renewable energy requirement must be met by in-state facilities and the remaining 50% with resources that can be shown to be deliverable into the state.

(ORC 4928.66) Additionally, utilities are required to implement energy efficiency and peak demand reduction programs that achieve a cumulative energy savings of 22% by the end of 2025, and reduce peak demand by 1.0% in 2009 and 0.75% annually thereafter through 2018.

The barriers that I have identified so far are:

Cost
Public Apathy
NIMBY
Government
Technology
