2. The Problem:Pollution
Fluorescent bulbs contain small amounts of mercury, a neurotoxin, and the companies and federal government haven't come up with effective ways to get Americans to recycle them.
"The problem with the bulbs is that they'll break before they get to the landfill. They'll break in containers, or they'll break in a dumpster or they'll break in the trucks. Workers may be exposed to very high levels of mercury when that happens," - John Skinner, executive director of the Solid Waste Association of North America
Not enough is being done to guarantee the safe disposal of CFL lights and incandescent lights so as of now they pose as a problem to the environment.

3. The Problem: Overuse of energy
Incandescents - The Usual Light Bulbs
80 percent of the energy produced by incandescent lights is heat, not light. As a result, incandescents are inefficient light sources.
The heat they produce drives up your electricity bill
While regular incandescent bulbs last usually between 750 to 1,000 hours before burning out, some long-life bulbs last up to 2,500 hours. The trade off is that long-life bulbs are less energy efficient and produce less light per watt.
Halogen Lights
While standard halogens are efficient, most people use much more wasteful high-wattage halogen tubes in their homes. It's estimated between 30 and 40 million free-standing torchiere lamps are in use today.
Unfortunately, these cheap and convenient halogen tubes waste energy by creating four times more heat than the average incandescent bulb. A 500-watt halogen reaches temperatures of over 1,200 degrees - creating a serious fire hazard. Curtains and other combustible materials can easily ignite if they get too close to the lamp.
Halogen torchieres are an example of low-price technology that become costly in the long run. Some stores often sell 300-watt torchieres for around $15 or less. Using that lamp for two hours a day will consume nearly 220 kilowatt hours of electricity in a year, at an average cost of $18. You'll spend more for electricity each year than the lamp cost in the first place.
Fluorescent Lights
These lights last only about 10,000 hours which is very little in comparison to the LED lights

4. WHY do we need LED?

5. Why LED? LED light bulbs last longer.
Without a filament to break or burn out, LED light bulbs can last for over 100,000 hours (that's over eleven years at full brightness). This lifespan is twice that of typical fluorescent bulbs and twenty times longer than incandescent light bulbs.
They are incredibly safe.
With so little energy lost to heat and so little energy used overall, LED light bulbs run cool, which means no injuries from burns or burnt down houses.
They are extremely durable thanks to their solid-state construction, so there's no broken glass to deal with, either.
LED Lightbulbs also have no hazardous materials or chemicals
No mercury or breakage off materials allows for less pollution

7. IT really works

8. IT really works Los Angeles
Energy use from streetlights fell from 190 million kilowatt-hours to 110 million kilowatt-hours. With improved efficiency being about 63% per year.
The city saved $8.8 million on its electric bill last year and another $3 million or so in maintenance costs.
In Los Angeles, where municipal lighting is mostly LED, the city reduced their annual energy consumption for public lighting by almost 40%
Sydney Australia
Saved almost $800,000 and reduced energy use more than 48% per year since March 2012
Buenos Aires
Buenos Aires is on the CityTouch system, they have 91,000 LED lights and they are now close to complete implementation. That’s already saving the city 50 percent on its energy costs per year.

10. How does it impact me?
Residential LEDs especially ENERGY STAR rated products use at least 75% less energy, and last 25 times longer, than incandescent lighting.
This drastically decreases utility bills.
Reduces my Carbon Footprint
An Energy Star light bulb replaces about six incandescent light bulbs because it lasts six times longer than the average light bulb.
If I were to use 20 light bulbs in your home, during the life of the energy-efficient bulbs, you've reduced the number of light bulbs you throw out from 120 to 20.
Hypothetically:
Replacing only one light bulb with an Energy Star-rated light bulb in every American home would reduce greenhouse gas emissions by 9 billion pounds, or about the amount from 800,000 cars reported by the U.S. Environmental Protection Agency Reports.
Cutting down on greenhouse gas emissions is a crucial element in fighting global warming and climate changes that may be a factor in catastrophic weather events.
This makes the planet i live on cleaner and safer.

13. Global Impact
Trials of outdoor LED lighting in 12 major cities across four continents found that LED lighting saved city governments an average of 53% on their energy bills compared to conventional lighting technologies. Energy savings in the trials varied from 18% to 85%, with 20 out of 27 products achieving savings of 50% or more. Cities participating in the pilots included New York City, Toronto, Hong Kong, London, Sydney, Adelaide and Kolkata.

14. Global Impact
Lighting is responsible for 19% of global electricity use and around 6% of global greenhouse gas emissions.
Doubling lighting efficiency globally would have a climate impact equivalent to eliminating half the emissions of all electricity and heat production in the EU3 ( France, United Kingdom and Germany) .
Efficient lighting boosts global prosperity.
In the United States alone, cutting the energy used by lighting by 40% saves the US $53 billion in annual energy costs

15. Global Impact
Nearly 5 percent of Africans without access to electricity, or some 28.5 million people, now use solar-powered LED lights. That's up from 1 percent five years ago
Led lights provide safe light to the 600 million African people living off-grid.

16. Global Impact Provide a better aesthetic
The streets just looks cleaner and brighter without the yellowish tint
