Energy Usage in Agriculture

2. What is Energy ?
The ability to work

3. What is a Hydrocarbon?
hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.
found naturally occur in crude oil, where decomposed organic matter provides an abundance of carbon and hydrogen which, when bonded, can catenate to form seemingly limitless chain

4. Common types of hydrocarbon fuels
Gasoline
Diesel
Natural Gas
Propane
Kerosene
Coal

5. Another type of energy common to every day life is
Electrical

6. What is electrical energy used for ?
Lighting and heating homes
Efficient transportation
Modernized irrigation system ( changes in diesel engines to electrical engines)
As a component in internal combustion engines

7. Nuclear Energy
Heat generated radioactive decay to create steam which turns turbines to drive generators.

8. Positive Aspects to Nuclear Energy
Less pollution
Cheaper kilowatt cost over a period of time

9. Alternative energy sources
Biofuel
Biomass
Wind
Solar
Hydropower

10. Negative Aspects to Nuclear Energy
Heat generated water that has to be cool extensively before re entering the environment
Dangers from radioactive releases
How to properly dispose the wastes

11. Bio Fuels
Renewable energy from biological sources

12. Examples of common bio fuels
Bio diesel
Ethanol ( an alcohol product)
Methane gases ( derives from various waste products)

13. Biomass Plant matter rich in cellulose
Biomass power- electrical power generated from burning plant matter

14. Examples of uses for biomass power
Burning of bagasse to create steam to generate energy operate sugar mills
Most common use for biomass is the burning of wood to heat homes and cook.

15. Wind energy uses Power of wind used to turn a wind mill to drive pump
Now used to turn turbines to generate electricity

16. Solar Energy
Conversion of sunlight to electrical energy through the use of solar panels
Newest form of renewable energy

17. Hydropower Energy
Moving water used to turn turbines which turns electrical generators
Ex: Toledo Bend Dam
