2. What is nonrenewable?
Natural resources that cannot be regenerated on a scale from which it is consumed.
Examples are fossil fuels like coal, natural gas, and oil.
A., B C., C., A., B.

3. Fossil Fuels
We need to decrease our dependency on these… 1. to reduce our foreign dependency. 2. to reduce our carbon emissions because it is contributing to climate change. 3. because they are nonrenewable and we will run out someday.
A. , B., C., A., B.

4. What is renewable?
A naturally occurring raw material or form of energy that will be replenished through natural ecological cycles or sound management practices.
Examples include solar, wind, geothermal, and biomass energy.
A., B., B. , C D.

5. Vocabulary
Carbon footprint-A representation of the effect human activities have on the climate in terms of the total amount of greenhouse gases produced.
Efficiency-The more ecologically aware use of energy in order to reduce economic costs and environmental impacts.
Emissions-substances discharged into the air.
Overconsumption-the use of resources at a rate that exceeds the ability of natural resources to replace them.
Sustainability-the extraction of resources at a rate not exceeding nature’s capacity to replenish them.

6. Solar Energy
Solar Energy is the energy emitted from the sun’s radiation. It can either be passive or active.
Passive solar energy is when sunlight is absorbed on dark surfaces.
Active solar energy is the conversion of solar energy to electrical energy using panels.
RENEWABLE!
A., C., C., D.

7. Pros and Cons of Solar Energy
No emissions.
Free after initial costs.
Sustainable
Tax breaks
Cons
Expensive initially.
Clouds/bad weather
Aesthetics
Only work during sunshine times.
Snow or leaves covering panels.
A., C., D.

8. Wind Energy
Wind energy is energy from the movement of the wind across the Earth. The energy is a result of the heating of our oceans, Earth, and atmosphere by the sun.
The U.S. has more than 400 times the wind potential than it is currently capturing.
RENEWABLE!
A., C., C., D

9. Pros and Cons of Wind Energy
Emissions free.
No extraction costs.
Sustainable.
Reduces foreign dependency.
Predictable price.
Cons
Lack of wind makes it an unreliable source.
Unsightly.
Noise.
Location issues.
Can be dangerous to birds and bats.
A., C., D

10. Geothermal Energy
Geothermal energy is derived from the heat within the interior of the Earth.
RENEWABLE!
A., C., C., D

11. Pros and Cons of Geothermal Energy
Minimal carbon footprint.
Renewable.
Massive potential.
Stable/Reliable
Cons
Still produces emissions and other pollutants.
Surface instability.
Expensive.
A., C, D

12. Biomass Energy
Biomass energy is plant material, vegetation, or agricultural waste used as fuel or energy source.
Plants used include corn, sugar, and algae.
RENEWABLE!
A., C., C, D

13. Pros and Cons of Biomass Energy
Renewable.
Widely available.
Low cost production.
Low carbon emissions.
Can convert waste into fuel.
Cons
Land utilization.
Can lead to deforestation.
Requires water to grow.
Still produces emissions.
Drives cost of food up.
Plants aren’t that efficient.
A., C, D

14. Nuclear Energy
Nuclear energy is the energy released by the nucleus of the matter as a result of nuclear fission.
Needs uranium which is a nonrenewable resource.
NONRENEWABLE!
A., C, C., D

15. Pros and Cons of Nuclear Energy
No CO2 emissions.
Low operating costs.
Large power generating capacity.
No pollutants.
Cons
High unknown risk.
Long construction time.
Waste lasts 200, ,000 years
Target for terrorism.
Non-renewable.
Radiation.
A., C, D

16. What next?
“Fossil fuels-coal, petroleum and natural gas, provide almost 90% of the energy used to sustain our way of life.” –Dr. Falcone
“Renewables receive less than 1% of the subsidies spent every year on fossil fuels.” –Bill Kern
Less than 3% of the U.S. produces energy from renewable resources.
We need to increase our usage of renewable resources so we can limit our foreign imports of oil, and become more sustainable.
Utilizing the renewable resource that works best in your area would make huge strides in the movement toward a greener life.
B., C., D
