9. Global Lighting Electricity Use
Emerging markets are driving dramatic
increases in lighting electricity use. 9

10. United States
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.

21. Smart Technology
Instant On = No Warm Up Period
Dimmable = Additional Energy Savings

24. Environmental Sustainability

25. Environmental Sustainability
Even “better” products can
sometimes be very bad.
25

26. Environmental Sustainability
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. 26

27. The Case for Conservation
Saving electricity is cheaper than creating it.
27

28. The Case for Conservation
The less efficient the light, and the shorter its life, the
more beneficial an LED lighting upgrade will be.
28

29. The Case for Conservation
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.

30. The Case for Conservation
What about conserving….
30

31. The Case for Conservation
Companies with more profits
can hire more…
31

32. The Case for Conservation
People who have to spend less on electricity
to light their homes can buy more…
32

33. The Case for Conservation
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.

34. Case Studies & Examples
National & Local
34

35. National Case Studies
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.
35

36. National Case Studies
Replaced 25 parking lot lights.
58% reduction in electricity while
maintaining IESNA illuminance
recommendations.
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.
36

37. Local Case Studies
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.
37

38. Local Case Studies
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.
38

39. Local Case Studies
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.

40. What if?...
…. we could reduce lighting
electricity usage by 50%?

41. In the United States we could…
Reduce annual greenhouse gas emissions equivalent
to taking 362,845 cars off the road.

42. In the United States we could…
Reduce annual electricity consumption enough to
power 24 million US homes.

43. In the United States we could…
Shudder 27 nuclear power plants. (41% of capacity)
Source: U.S. Energy Information Administration (EIA) 43

44. 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.
