1. Alternative Energy & Non-Renewable Resources
By: Zach Battaglia, Emmaly Harrell, and Jacob Gianakopoulos

2. What is Alternative Energy?
It is a different option to using natural resources for power such as oil
It creates little to no CO2 emissions
It is renewable
Ex. Hydroelectricity, wind power, and solar power
Wind Power
Water Power
Solar Power

3. What are Non-renewable Resources?
They are sources of energy that we use that are found in nature
Creates CO2 emissions
Are usually non-renewable
Ex. Coal and Petroleum
Petroleum
Coal

4. Pros and Cons of Hydroelectricity
Creates no emissions except for when its being built
Most renewable source of energy in the world
We can adjust how much energy we need by reducing or increasing flow output
Cons-
Expensive
If droughts happen, people may lose power
There are limited reservoirs, but more are being built

5. Pros and cons of Wind Power
No emissions
One wind turbine can produce enough energy to power 600 homes
Prices to build turbines are dropping
Renewable
Cons-
Can be a threat to wildlife
Expensive
The wind is unpredictable

6. Pros and Cons of Solar Power
Renewable
Sunlight is abundant
It is environmentally friendly
Reduces energy costs
Low maintenance
Cons-
Expensive
Requires a lot of space
Needs exotic materials to make them
Energy storage is expensive

7. Pros and Cons of Petroleum
Has a higher energy density (one kilogram of burnt oil can give off 10,000 kilocalories)
Abundant
Cheap to extract
Used to move vehicles longer and faster than other energy sources
Cons-
Pollution
It is possible that it can run out in the coming decades
It is non-renewable
If spilled, can cause a major environmental disaster

8. Pros and Cons of Coal Pros- Abundance Low Capitol investment
High Load Factors
Cons-
Pollution
People die mining it
Devastation of nature around the coal mines
Thermal Plants (where they use coal), give off deadly gases such as sulfur dioxide, carbon monoxide, mercury, selenium, and arsenic

9. Costs for Alternative Energy
Hydroelectricity- $2.12M for a 500kW dam
Wind Power- $50,000-$80,000 for a 10kW turbine (can power a large home)
Solar Power- $50,000 for a 6.5 kW system

10. Cost of Non-renewable energy
Petroleum- currently $59.60 per gallon
Coal- $46.97 for one short ton (2000 Ibs)

11. Problems for Us
Fuels such as petroleum are running out and we need an alternative. The question is which alternative do we use? We can either switch over to coal which gives of pollution but is very cheap or, we can switch to a renewable source of energy that has no emissions but is expensive. Each have benefits but also have a cost to using them.
