Emerging markets are driving dramatic increases in lighting electricity use.

United States

10

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.

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.


28

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


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.


30

What about conserving….


31

Companies with more profits can hire more…


32

People who have to spend less on electricity to light their homes can buy more…


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%?

40

In the United States we could…

Source: U.S. Energy Information Administration (EIA) 41

Reduce annual greenhouse gas emissions equivalent to taking 362,845 cars off the road.



Reduce annual electricity consumption enough to power 24 million US homes.



Shudder 27 nuclear power plants. (41% of capacity)



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.
