HMMMM....
  • What do you think nonrenewable resources are?
  • Break it down...
  • Nonrenewable?
  • Resource?

4
NONRENEWABLE RESOURCES
  • A nonrenewable resource is a natural resource
    that cannot be re-made or re-grown at a scale
    comparable to its consumption.

5
Renweable Resource is
  • A renewable resource is a natural resource which
    can replenish with the passage of time, either
    through biological reproduction or other
    naturally recurring processes.

Five Factors that Influence the Value of Fuel
  • Cost
  • Availability
  • Safety
  • Energy Content
  • Byproducts of the fuels use

USA vs World

NUCLEAR ENERGY
  • Nuclear fission uses uranium to create energy.
  • Nuclear energy is a nonrenewable resource because
    once the uranium is used, it is gone!

13
A 1,000-megawatt nuclear plant is refueled once a
year, whereas a coal plant of the same size
requires 80 rail cars of coal a day
14
COAL, PETROLEUM, AND GAS
  • Coal, petroleum, and natural gas are considered
    nonrenewable because they can not be replenished
    in a short period of time. These are called
    fossil fuels.

15
HOW IS COAL MADE ???
16
HOW ARE OIL AND GAS MADE ???
17
WHAT WAS THE DIFFERENCE BETWEEN COAL AND OIL/GAS?
18
Differences
  • Coal is a solid. It is mostly carbon. It is made
    from mostly plant materials.
  • Oil is a liquid. It is a mixture of hydrocarbons.
    It is more animal materials. Its composition is
    different depending on where it is found.
  • Natural gas is a gas. It is mostly methane, CH4.

Heat produced by burning pulverized coal in a
furnace boils water to produce steam that spins a
turbine to produce electricity. The steam is
cooled, condensed, and returned to the boiler for
reuse. Waste heat can be transferred to the
atmosphere or to a nearby source of water. The
largest coal-burning power plant in the United
States, located in Indiana, burns three 100-car
trainloads of coal per day
Coal-burning power plant.
21
Lowest Boiling Point
Gases
Science refining crude oil. Components of
petroleum are removed at various levels,
depending on their boiling points, in a giant
distillation column. The most volatile components
with the lowest boiling points are removed at the
top of the column.
Gasoline
Aviation fuel
Heating oil
Diesel oil
Naphtha
Grease and wax
Heated crude oil

Methane Hydrates-fossil fuel of future?
  • As natural gas from shale becomes a global energy
    "game changer," oil and gas researchers are
    working to develop new technologies to produce
    natural gas from methane hydrate deposits.

24
Methane risks
  • Methane hydrates are sensitive sediments.
  • They can rapidly dissociate with an increase in
    temperature or a decrease in pressure. This
    dissociation produces free methane and water
  • The conversion of a solid sediment into liquids
    and gases will create a loss of support and shear
    strength. These can cause submarine slumping,
    landslides or subsidence that can damage
    production equipment and pipelines

25
Oil Reserves vs Oil Resources
  • Oil reserves are oil deposits that can be
    extracted profitably at current prices using
    current technology.
  • Oil resources are quantities of petroleum
    estimated to be potentially recoverable from
    undiscovered accumulations by application of
    future development projects.

26
HMMMM....
  • If nonrenewable resources are resources that
    cannot be re-made at a scale comparable to its
    consumption, what are renewable resources?

27
RENEWABLE RESOURCES
  • Renewable resources are natural resources that
    can be replenished in a short period of time.
  • ? Solar ? Geothermal
  • ? Wind ? Biomass
  • ? Water

28
SOLAR
  • Energy from
  • the sun.
  • Solar power is the conversion of sunlight into
    electricity, either directly using photovoltaics
    (PV), or indirectly using concentrated solar
    power (CSP)

35
GEOTHERMAL
  • Geothermal energy is the heat from the Earth.
    It's clean and sustainable.
  • Resources of geothermal energy range from the
    shallow ground to hot water and hot rock found a
    few miles beneath the Earth's surface, and down
    even deeper to the extremely high temperatures of
    molten rock called magma.

Geo-Thermal Energy
38
WIND
  • .
  • Wind power is the conversion of wind energy into
    a useful form of energy, such as using wind
    turbines to make electrical power, windmills for
    mechanical power, windpumps for water pumping or
    drainage, or sails to propel ships.

BIOMASS
  • Energy from burning organic or living matter.
  • As an energy source, biomass can either be used
    directly via combustion to produce heat, or
    indirectly after converting it to various forms
    of biofuel.

44
Bio Diesel
45
Ethanol Fuel
46
Green Algae
  • http//www.history.com/topics/earth-day/videosgre
    en-algae
  • Algae fuel or algal biofuel is an alternative to
    fossil fuel that uses algae as its source of
    natural deposits

47
WATER or HYDROLOGIC
  • Energy from the flow of water.

48
Tidal and Wave Power

49
Tidal Power
  • Tidal power, also called tidal energy, is a form
    of hydropower that converts the energy of tides
    into useful forms of power, mainly electricity.

50
WAVE POWER
  • Wave energy is produced when electricity
    generators are placed on the surface of the
    ocean. The energy provided is most often used in
    desalination plants, power plants and water
    pumps. Energy output is determined by wave
    height, wave speed, wavelength, and water density

51
Ocean Thermal Energy Conversion OTEC
  • Ocean thermal energy conversion (OTEC) uses the
    temperature difference between cooler deep and
    warmer shallow or surface ocean waters to run a
    heat engine and produce useful work, usually in
    the form of electricity. OTEC is a base load
    electricity generation system, i.e. 24hrs/day all
    year long.

Hydrogena future fuel source?
  • Hydrogen fuel is a zero-emission fuel which uses
    electrochemical cells, or combustion in internal
    engines, to power vehicles and electric devices.
  • It is also used in the propulsion of spacecraft
    and can potentially be mass-produced and
    commercialized for passenger vehicles and aircraft

54
Hydrogen
55
Energy Efficiency
  • The percentage of energy put into a system that
    does useful work.

56
Cogeneration CHP
  • The production of two useful forms of energy from
    the same fuel source.

57
Energy Conservation
  • This means to save energy.

President Obama called for an average of 35.5 mpg
for new cars, vans, and SUVs in the United States
by 2016. This is lower than Chinas current fuel
economy standard for new vehicles and much lower
than the 42.5 mpg standard that China has set for
2016
60
How Can We Make the Transition to a More
Sustainable Energy Future?
  • We can make a transition to a more sustainable
    energy future by greatly improving energy
    efficiency, using a mix of renewable energy
    resources, and including environmental costs of
    energy resources in their market prices.

61
Transition to a More Sustainable Energy Future
  • For each energy alternative
  • How much available next 25-50 years?
  • Estimated net energy yield
  • Total costs
  • Necessary subsidies and tax breaks
  • How affect economic and military security
  • Vulnerability to terrorism
  • Environmental effects

62
Transition to a More Sustainable Energy Future
  • Gradual shift from centralized macropower to
    decentralized micropower
  • Greatly improved energy efficiency
  • Temporary use of natural gas
  • Decrease environmental impact of fossil fuels
