Intro
Energy
Our current energy consumption
3.3TW US
13TW World
Our Projected Statistics
28TW World
Our current mediums to extract energy
Coal 51%
Renewable 1%
Reason why we are trying to go solar
Too much CO2 Emissions
Escalating our Ozone greenhouse effect
Thesis: Based on scientific data, our resources for non-renewable fuel is both destroying our ecosystem as well as exhausting our supply for our resources. With the need for clean and renewable resources to fuel our planet, solar and wind farms are needed to become the or a major energy producer.
Body 1: Solar Pros
Free energy
Requires Sun
The sun's rays can fuel our planet for an entire year for only one hour of required exposure time
Compact can go on rooftops
Can supply energy in remote areas

Cooling vaccines using Solar power in places like Africa
Cooling Vaccines need a constant temperature
Excludes places that already have constant power
For places that have little or no reliable power, this would be used
Body 1: Solar Cons
Cost of the item
Sun Exposure
Washington
Oregon
Cloudy weather

“east-west field of view (FOV) ≥ ±60°, a north-south FOV ≥ ±25° , a system power efficiency (SPE) ≥ 40%”
Amount produced by a unit
Body 2: Wind Pros
Free energy
Clean energy
Can place on farms and forget
Can run at night
Body 2: Wind Cons
Requires electric grid to be laid down before instillation
Big upfront cost
Wind is not a reliable and constant source
Noise
Body 3: Which one is better?
State → which one is better?
Based on location and purpose
Location
Sun → Solar
No sun → Wind
Purpose
Each need technical advances to be considerable
Solar with solar paint

Body 4: Possible Applications: Solar Street signs

Fixes to street lights:
Halogen → LED
Solar
Fixing when lights die
Uses in places without electricity
Conclusion
Address the need for improved technology
Solar
Solar paint
Solar farms
Wind
They cannot be the leading producer at the moment, but transitioning would be great

Gives specifications on how to get a really accurate solar panel. I could not get the rest of the article, but it seems very promising to look further into.

This one caught my eye from the start with a very common question, "Solar Panel Traffic Signals". 629-644pg. Goes in depth with the power usage of all the traffic lights (halogen and LED versions) and the savings. Gives the most effective locations, and how much it would cost to fit those locations with solar panel traffic lights. It also states in the conclusion that solar panels will help the traffic lights in the event of a blackout, which could provide to be quite useful in some cases.

Even though this is criticized in places where electricity is readily available, this option still proves useful everywhere else. As the article explains, the Vaccines need to be cooled to 3~5 degrees Celsius, without power variation for the best results. Unfortunately, this is good news for places where power is hard to some by, and has a lot of sun.
