Renewable resources

• Renewable means we can replace the resource in a
  reasonable time, or the resource is not used up.

3
Non-renewable

• Non-renewable once used, the resource cannot be
  replaced. More is not being made as the
  production takes millions of years or just the
  right conditions.

Renewable or Nonrenewable?

• Oil Hydrogen uranium
• Wind Solar Geothermal
• Coal natural gas Hydroelectric
• Biofuels Continue slide show

5
Oil

• Oil is non-renewable as it takes millions of
  years and just the right conditions to create.

6
Wind

• Wind is renewable since it is not used up but is
  always being generated by temperature differences
  in ocean currents and on land.

7
Hydrogen

• Hydrogen is renewable as we can make it from
  water.
• Return to Quiz

8
Uranium

• Uranium is not renewable since uranium is made
  during the supernova stage of a star. We can
  find uranium deposits from space and while we
  have a lot, it is not renewable.

11
Natural Gas

• The vast stores of natural gas are not renewable
  as they were made by fossil fuel deposits.

12
Coal

• Coal, like oil, is formed from fossil fuel
  deposits.
• It is not renewable.

13
Hydroelectric

• Hydroelectric is renewable since snow in the
  mountains happens each year.

14
Biofuels

• Biofuels are renewable since they are produced
  from oils, sugars, or starches obtained from
  plants.
• Methane, aka natural gas, is also being
  collected from the decay of plants and other
  organic material in places like landfills.

Alternative Energy Essay

• Part two
• Choose one alternative energy source that you
  think is promising and explain in a 1-2 page
  essay why you think it holds promise. You must
  cite your resources, this includes information
  you gather from class lectures. You must also
  include new research other than that presented in
  class and cite your source.

Goals of alternative energy

• 1. Provide alternatives to the limited supply of
  oil.
• 2. Provide energy that does not increase the
  greenhouse gas, carbon dioxide.
