Renewable Energy

Energy sources that can be replaced, or replenished.

NewsNews• Yesterday, scientists finished decoding the DNA of a Wooly Mammoth.

• Not used to make one with cloning, but instead used to understand how elephants have evolved.

NewsNews• NASA is celebrating 10 years of the International Space Station.

• 167 visitors, from 15 countries.

• New Shuttles by 2010, retire the current ones! Obama


Hydroelectric-

Electricity being made by hydro-water


Wood/Forests-Energy stored in trees in the carbon chemical bonds. Energy is old sunlight!

Extra-(maple syrup)


Photovoltaic-

Electricity being made by converting Sunlight/Visible Light.

Solar Panels


Tidal Turbine-

Energy production from the movement of ocean tides


Wave Turbine-

Electricity produced by the movement of waves.


Bio-diesel-

Fuel made from vegetables and grain


Wind Turbine-

Electricity produced from the conversion of wind.


Non-Renewable

Energy sources that once used, are non replaceable.


Fossil Fuels•Ancient Stored Sunlight•Coal, Oil, Natural Gas•Considered the Catalyst for Accelerated Global Warming

Energy TermsEnergy TermsCoal-

Energy Source made of preserved swamp ecosystems. Water/Mud preserved. Largest world-wide energy source for producing electricity


Oil-Petroleum

Naturally occurring liquid found in Earth, comprised of ancient Zooplankton and Algae, hydrocarbons(oceans)


Natural Gas

-Source of energy from swamps, marshes and landfills. Ancient to recent. Bondies Island


Nuclear Power Plants

-Energy produced by splitting atoms and using the heat to make steam and spin turbines


Unsure?!

These energy sources have potential to be either renewable or non-renewable

HomeworkHomework

Hydrogen

-Energy stored in the attractive bonds of Hydrogen gas. H2 want to be in a water state.

Conservation of energy-

Law- Energy can neither be destroyed or created. All energy must be accounted for


•Temperature-Average kinetic energy KE of the individual particle

Thermal EnergyThermal Energy• Total amount of Kinetic Energy from Particles. As Kinetic Energy of particles increases, so does the Thermal energy.(Heat Energy) The particles move faster.

Energy TransferEnergy TransferHeat-Movement of Thermal energy from a substance at a higher temperature to another at a lower temperature

Energy TransferEnergy Transfer

Conduction-Transfer of Thermal Energy, without particles moving. Transfer by touching, Direct Contact

Transfer of EnergyTransfer of Energy

Convection-

The transfer of energy by movement of Fluids. Earths mantle as well as water in a pot on the stove.

Energy TransferEnergy Transfer

Radiation-Transfer of energy by or through EM Waves (Electromagnetic). Sun’s rays, hot lamps, tanning salon.

Bell Work #1Bell Work #1How would you

Describe a Solid?

•Packed together tightly in relatively fixed positions. Can Vibrate!

Bell Work #2Bell Work #2How would you Describe a Gas?

•Moving so fast that they do not stay close to one another. Expand to fill space!

Bell Work #3Bell Work #3How would you

Describe a Liquid? • Particles held together, but not so tightly that they can’t move past one another. No Shape, but Volume!

•All Based upon the Amount of KE

Energy TermsEnergy Terms• Insulator-

Nature of material and it’s particles is resistant to absorbing Kinetic Energy


• Conductor-Nature of material and it’s particles transfers Kinetic Energy Easily!
