1. 16.2 How Can We Cut Energy Waste?
By: Bary Goukis and Alex Belovich

2. Why Are We Wasting So Much Energy& Money?
Cutting energy waste will not solve all of our
energy problems, but it is a good first step.
Cheap fossil fuels.
limited incentives for consumers.
People resist change.

3. We Can Use Renewable Energy to Provide Heat & Electricity
One of the principles of sustainability include using solar energy.
Comes directly from the sun, or from wind and water.
Also geothermal.

4. Good News! Tax breaks, subsidies, funding.
By 2025, 20% Renewable resources.
50% by 2050

7. The Search for Better Batteries
Thomas Edison
First Rechargeable Battery
Nickel
Lead-based in cars.
Difficult to make affordable and durable.
Lithium Ion Batteries
Pros
Light,
Lot of energy in small space.
Cons
Tend to overheat.
2x expensive as current hybrid car batteries.

9. Current Research Better Li-ion batteries. Nanotechnology Virus
Nanophosphate
Lengthen battery Life
Won't heat up
Virus
Coats itself with conducting materials
Forms a miniscule nanowire.
Goal: Attach the wires to make a battery-like cell.
Ultracapacitor
Battery-like
Stores and releases energy very quickly
Would make batteries obsolete

10. United States Increase electric energy
Don't depend on Middle East for oil or Asia for batteries.
Radical change in Infrastructure
Use Eco-Labeled Products (Energy Star, etc.)

11. European Union
Universal Rating System on appliances
