What is Energy ? The ability to work

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

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

Another type of energy common to every day life is Electrical

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

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

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

Alternative energy sources Biofuel Biomass Wind Solar Hydropower

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

Bio Fuels Renewable energy from biological sources

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

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

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.

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

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

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