Introduction

Introduction

  • The costs of wasting energy

  • Our project, why we are doing it, and how we went about it


How much electricity does lighting use

How much electricity does lighting use?

  • Total Electricity: 10,656 kWh per year per household, 1.1 trillion kWh for the country for residential lighting

  • 9.1 percent of electricity to lighting-110.6 billion kWh for the nation.


How much does this cost

How much does this cost?

  • 8.3 cents per kWh

  • 9.2 billion dollars nationally for residential lighting alone

  • One 60-watt light bulb on for an hour, is 0.06 kWh (60/1000)

  • One 20-watt light bulb on for an hour is 0.02 kWh

  • For Stanford university room, 2x60 watt incandescent light-bulbs run for 3 hours a day + 4x20 watt ceiling fluorescent bulbs for 10 hours a day=.36+.8 kwH/day=423.4 kwH/year

  • 423.4*.083=$35 per year

  • For entire freshman class, about $60,000

Powering a 100 watt lightbulb for a year

Powering a 100 watt lightbulb, for a year:

  • 740 lbs coal

  • 5 lbs. SOx (source of acid rain)

  • 5 lbs. NOx (source of acid rain, smog)

  • 1,852 lbs. COx (greenhouse gas)

Our project an overview

Our Project: An Overview

  • Lighting: An easy way to address energy consumption

  • Numerous approaches to the problem

  • Our focus: Light, Power, Power Management, Light Direction


Lighting a bright efficient future

Lighting: A bright, efficient future

  • Why LED's

  • Current Technology

  • Future Technology


Why led s

Why LED's

  • Benefits -

    • Life Span

    • Durability

    • Maintenance

    • Flexibility


What is an led

What is an LED?

  • A solid state light source that uses an electrical signal run across a semiconductor


Current technology

Current Technology

  • Very attractive options for certain situations

    • Traffic Lights

    • Car Lights

  • Not yet feasible everyday light replacements

    • No market = high cost and low production

  • There is a lot of research being conducted in LED technology because of its potential


Future technology

Future Technology

  • Most promising lighting technology

  • Cost Reducing

    • 50% reduction on energy used for lighting

    • 10% worldwide total energy reduction

  • Environmentally Friendly


Power plugging in to green energy

Power: Plugging in to green energy

  • Sunny Day  1000 W/m2

  • Photovoltaic (PV) module:

    Solar Cells

    • Single crystal silicon

    • Polycrystalline silicon

    • Others

Storing the energy

Storing the Energy

  • Deep Cycle Batteries

  • Utility Grid

    • Inverter: DC  AC

  • Expensive: $9 per Watt

    • prices expected to decrease in the future

Relevant projects

Relevant Projects

  • BJ’s Wholesale Club

    • 12K sq. ft., 1330 - 2x4ft. Panels, 52-kW

    • Saved $1M, 12M kW-hr/yr

  • Synergy House

    • 7.5 kW

    • $77,816

    • Saves 11,164 kW-hr/yr, $1,987/yr

Power management switching it up for the better

Power Management: Switching it up…for the better!

  • Cutting down on

    unnecessary power

    consumption

  • Three main lighted

    areas in any dorm…

  • Dorm Room, Hallway,

    and Lounge area.


Power management dorm room

Power Management – Dorm Room

  • Keep manual light switches

  • Possible Improvements

    • “Dimmer” switches  $20-30

    • Power Management workshops

Power management hallway

Power Management – Hallway

  • Hallways aren’t commonly used during certain hours of the day

  • Timers  $40-50

  • Motion Sensors  $20-60

Power management lounge

Power Management – Lounge

  • During the day  Plenty of natural light

  • Big Windows

  • “Photosensors”  $40-60

Lighting direction putting lighting in its place

Lighting Direction: Putting Lighting in its place

  • Individual Needs

  • If the dorm doesn’t meet these with efficient lighting, students will be forced to meet them on their own

  • Inefficient solutions


Three choices

Three Choices:

  • One overhead light

  • Desk lamps

  • All-included system


Our solution include high efficiency desk lamps

Our Solution: Include High Efficiency Desk Lamps

  • Higher initial purchase costs

  • Reduce student costs

  • Decrease energy consumption
