With a total of 208 billion kWh needed for lighting in American homes, we need the equivalent of 13 nuclear power plants just to meet residential lighting demand.

Even “better” products can sometimes be very bad.

Environmental Sustainability
26
Where are CFLs made? Not in the U.S., under strict environmental regulation. CFLs are made in India
and China, where environmental standards are virtually non-existent.
The Case for Conservation
27
Saving electricity is cheaper than creating it.
The Case for Conservation
28
The less efficient the light, and the shorter its life, the more beneficial an LED lighting upgrade will be.
The Case for Conservation
29
A 50% reduction in lighting electricity usage = An 11% reduction in global energy use.
In the US lighting electricity use for residential and commercial facilities combined equaled 535 billion
kilowatt‐hours in 2009. 13.6% of overall electricity usage.
Even with a 28% adoption rate for CFL’s, US Households throw away 5.5 million light bulbs a day.
The Case for Conservation
30
What about conserving….
The Case for Conservation
31
Companies with more profits can hire more…
The Case for Conservation
32
People who have to spend less on electricity to light their homes can buy more…
The Case for Conservation
33
Lighting upgrades are consistently rated as one of the top 1 or 2 recommended measures for
conservation by energy auditors.
Breakeven is generally under 36 months and often under 12 months. Rebates and tax incentives can
reduce the breakeven point even further.
Assuming a 10% net profit margin, a business that saves $1,000 a year in electricity has made the same
net affect as increasing revenue by $10,000.
Case Studies & ExamplesNational & Local
34
National Case Studies
35
Replaced nearly all incandescent and halogen lights with LED in over 8,000 stores in US, Canada, Europe & Asia.
80% reduction in lighting energy consumption.
$30/bulb savings per year equivalent savings of ½ barrel of oil in CO2.
Reduced average stores energy consumption by 7%.
Over 250,000 LED Lamps installed in total.
National Case Studies
36
Replaced 25 parking lot lights.
58% reduction in electricity while maintaining IESNA illuminancerecommendations.
44,000 kWh savings in electricity per year – an equivalent of 30.4 tons of CO2 removed from the environment.
$15k in electricity and $10k in maintenance savings per year.
Project payback in 3 years.
Local Case Studies
37
Replaced 600 low pressure sodium street lamps throughout the city.
Immediate savings of $3,000/month in electricity.
Significant maintenance savings
Better quality of light with reduced glare and light‐spill.
12 year projected lamp life – 3x the original lighting.
Project cost of $425,000.
Local Case Studies
38
The first city in the valley to install LED streetlights on a wide scale.
Approx. 25% of city lights converted.
Expected to reduce energy consumption by 42% ‐ equal to 853 metric tons of greenhouse gas emissions being removed from the environment.
Funding made possible by an ARRA grant.
Local Case Studies
39
Switched out lighting in six parking lots to LEDs.
Expected to save $127,000 annually in energy and maintenance costs.
2,000 lights will reduce ASU’s annual energy consumption for parking lot lighting by 59%.
A reduction of 1.5m kWh, saving the equivalent of emissions from 208 passenger vehicles.
What if?...
…. we could reduce lighting electricity usage by 50%?

Shudder 27 nuclear power plants. (41% of capacity)
In the United States we could…

Shut down 76 coal‐burning power plants. This alone would save 167 billion gallons of water use and 281 million tons of carbon dioxide from being released into the environment.
