    Energy from a Global Perspective

    This presentation is unlike any you have ever seen on energy. We take off

    the rose-colored glasses, we look at energy from a pragmatic and globalperspective to give you a basic and essential understanding of:

    Where energy comes from and how it is used

    Why the demand for energy is always increasing

    Why conservation and efficiency are not solving the problem

    When reading about energy do you askbut what does this really mean?

    Then you should find this presentation to be useful

    This presentation will change the way youthink about our global energy situation

    Some Questions Addressed Here

    The answers to these questions will surprise you,they are not what you would normally think

    3

    Can energy be described in a more simple and consistent way?

    What is the difference between energy production and energyconsumption?

    Where is most energy actually consumed?

    How much energy is used by households and autos?

    How much have energy costs really increased?

    What if everyone drove a fuel-efficient car or switched tofluorescent bulbs?

    How much can solar and wind really do for us?

    Why is the demand for energy always increasing?

    Why cant energy be explained in

    simple, consistent terms? It can . . .

    Are You Confused About Energy?

    32 Billion barrels of oil yearly!

    1.7 Billion gallons of gasoline daily!

    67 EJoules of electricity yearly!

    6.5 Billion short tons of coal yearly!

    370 Gigawatts of nuclear power!

    9 Gigawatts of solar power!

    etc., etc. !

    A chart used to explain energy (DoE /EIA/Sandia)

    No wonder; the way energy information is presented has us allconfused, it might as well be written in a foreign language

    The BTU is a relatively small amount of energy; a can

    of soda contains about 150 Calories or 600 BTU

    Global energy is measured in quadrillion BTU or QBTU*

    The U.S. Energy Information Agency (EIA) uses QBTU

    The only thing you will need to keep in mind is:

    Millions > Billions > Trillions > Quadrillions*

    106 > 109 > 1012 > 1015

    The BTU Approach to Global Energy

    Global energy production is approaching500 QBTU per year

    The BTU approach allows you to see the wholeglobal energy picture, not just pieces of it

    Yes, costs are coming down for solar and wind, but

    Solar and wind can only produce electricity

    They are only part-time workers

    There is no viable way (yet) for mass storing their energy

    Because of these inherent limitations, solar andwind can only be supplemental energy sources

    What can solar and wind energy do for us?

    at least until massive storage

    capability becomes a reality

    Solar and Wind Energy?

    Electricity generation requires about 40% of global energyproductionAssuming (optimistically) that solar and wind combined work atleast 40% of the time, then by simple math;

    40% x 40% equals 16% of our global energy needs

    Growing biofuels requires large amounts of farmland

    which otherwise could be used to grow food

    Relatively large amounts of energy are required for production;(60% of the energy in ethanol is fossil fuel based*)

    Biofuels can only be a supplementalsource of global energy

    What can biofuels realistically do for us?

    Cellulosic plant sources grown on marginal land and low-energyproduction techniques (termites, algae, bacteria, etc.) to producebiofuels remain a future possibility, but until then . . .

    * Official USDA output/input production ratio of 1.67

    (disputed by many as being too high)

    Biofuels?

    Costs are coming down, but

    Energy Savings Initiatives: Looking Back

    We are now using energy 2 to 3 more efficiently, butconsumption continues on its relentless rise

    Since the early 1970s great strides have been made in

    conservation, efficiency and public awareness of energy

    Auto mpg has doubled

    More efficient appliances

    Building codes revised

    Clean Air Act initiated

    Recycling becomes routine

    Earth Day & Earth Summit

    Drive less, car pool

    Lower our thermostats

    Use fluorescent bulbs

    Get energy-eff. windows

    Buy a fuel-efficient car

    Use a clothes line etc.

    Energy Demand Keeps Growing Because . . .

    Energy does not hold still while we try to fix it

    Nearly two billion people still do not have electricity

    Several billion others would like to own an automobile

    Billions more would like to have bigger, better homes

    Everyone would like to become big-time consumers like us

    Can we blame them?

    Yes, the worlds population is increasing, but the demand for

    energy from those of us already here is increasing even faster

  • 8/14/2019 Understanding Global Energy

    22/28

    Most energy use is considered necessary and useful,

    at least by those using it

    Most energy savings initiatives focus on our cars and homes, i.e.personal solutions

    Personal Solutions Are Not Working

    Global energy demand is increasing at 2.0% yearlydespite all of our emphasis on Personal Savings

    Do you know of anyone who thinks they waste energy?

    But most energy is consumed in the Industrial and Commercial Sectors

    (i.e., on the goods and services we buy)

    Conservation and improved efficiency have not

    translated into reduced energy consumption

    Personal energy savings, although helping, are not solvingtheglobal energy problem

    What if every household in the worldswitched from incandescent bulbs to

    fluorescent light bulbs?

    Global energy consumption would be

    reduced by 3.5 QBTU or 0.7%

    Some What-If Examplesfrom the Global Energy Handbook

    What if every family in the world reduced

    their household electricity use by 10%?

    Global energy consumption would bereduced by 5.5 QBTU or1.1%

    With the demand for global energy increasing at 2.0%yearly, savings like these are quickly washed away

    Unfortunately, global energy consumption would

    not be reduced, only slowed down slightly

    The other uses of energy (non-auto)

    will continue to grow, regardless

    By then (2030) there will be nearly

    two billion cars in the world

    It will take about 20 years for the

    world fleet to reach 44 mpg avg.

    Near-Term vs. Long-Term Solutions

    In discussions on energy many will say not to worry;

    everything will be run using renewable energy sources

    solar and wind with mass storage capability; biofuels grownon arid land; platforms in space beaming down energy andnuclear fusion.Do not deny the possibility of these, just point that they arefar-term solutions, hopefully for our grand children or their

    grand children, they are not near-term solutions

    In most discussions on global energy the first casualtyis the distinction between near and far-term solutions

    The global energy perspective given here is for the near-term;

    the next 30 years or so when diminishing fossil-fuel suppliescombine with the dire predicted effects of greenhouse emissions

    Energy Consumption vs. Consumer Spending

    At the same time we are also bombarded to consume

    more: designer clothes, the latest high-tech gadgets, fast

    foods, new and better cars

    Unfortunately, energy consumption and consumerspending are two sides of the same coin

    Energy consumption is bad

    Consumer spending is good

    a least in the way our globaleconomy is currently structured

    Energy and spending are treated as

    two separate things in the media:

    We are constantly bombarded with pleas to save energy:drive less, turn down the heater, shut off the computer, usefluorescent bulbs, install energy-efficient appliances

    You now should have a better understanding of global energy

    You should see why conservation and improved efficiencyhave not been able to reduce the demand for energy

    You should see why the solution goes far beyond thecommercial and political slogans we hear daily
