Central Case: oil or wilderness on Alaska’s North Slope? ,[object Object],[object Object],[object Object]

Alaska’s North Slope consists of three regions ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

We use a variety of energy sources ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Fossil fuels are our dominant source of energy ,[object Object],[object Object],[object Object],[object Object]

Resources are renewable or nonrenewable ,[object Object],[object Object],[object Object],[object Object],[object Object]

Fossil fuels are indeed created from fossils ,[object Object],[object Object],[object Object],[object Object]

Fossil fuel reserves are unevenly distributed ,[object Object],[object Object],[object Object],[object Object],[object Object]

Developed nations consume lots of energy ,[object Object],[object Object],[object Object],[object Object]

Regions vary greatly in energy consumption

It takes energy to make energy ,[object Object],[object Object],[object Object],[object Object]

Energy returned on investment (EROI) ,[object Object],[object Object],[object Object]

Coal ,[object Object],[object Object],[object Object]

Coal use has a long history ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Coal is mined from the surface and below ground ,[object Object],[object Object],[object Object]

Coal varies in its qualities ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Coal contains impurities ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Natural gas ,[object Object],[object Object],[object Object]

Natural gas is formed in two ways ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Natural gas is often wasted ,[object Object],[object Object],[object Object],[object Object],[object Object]

Natural gas has only recently been widely used ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Natural gas extraction becomes more challenging ,[object Object],[object Object],[object Object],[object Object]

Offshore drilling produces much of our gas ,[object Object],[object Object],[object Object],[object Object],[object Object]

Heat and pressure underground form petroleum ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

The age of oil began in the mid-19th century ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Petroleum geologists infer deposit location and size ,[object Object],[object Object],[object Object],[object Object]

Not all oil can be extracted ,[object Object],[object Object],[object Object]

We drill to extract oil ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Primary and secondary oil extraction

Petroleum products have many uses ,[object Object]

We may have already depleted half our reserves ,[object Object],[object Object],[object Object],[object Object]

We are facing an oil shortage ,[object Object],[object Object],[object Object],[object Object],[object Object]

U.S. oil production has already peaked

Global oil production is peaking

Predicting an exact date for peak oil is hard ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Peaking oil production will have consequences ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Oil sands can be mined and processed ,[object Object],[object Object],[object Object],[object Object],[object Object]

Oil shale is abundant in the U.S. west ,[object Object],[object Object],[object Object],[object Object],[object Object]

Methane hydrate shows potential ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

These alternative fossil fuels have downsides ,[object Object],[object Object],[object Object],[object Object]

Fossil fuel emissions pollute ,[object Object],[object Object],[object Object],[object Object]

Coal mining affects the environment ,[object Object],[object Object],[object Object]

Coal mining harms human health ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Scientists anticipate negative impacts in ANWR ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Nations can become dependent on foreign energy ,[object Object],[object Object],[object Object]

The oil embargo of the 1970s caused panic ,[object Object]

Oil supply and prices affect nation’s economies ,[object Object],[object Object],[object Object]

The U.S. enacted policies to reduce foreign oil ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

The global trade in oil is lopsided

Residents may or may not benefit from reserves ,[object Object],[object Object],[object Object],[object Object],[object Object]

How will we convert to renewable energy? ,[object Object],[object Object],[object Object],[object Object],[object Object]

Our reliance on fossil fuels has consequences

Energy conservation ,[object Object],[object Object],[object Object],[object Object]

Energy conservation has followed need ,[object Object],[object Object],[object Object],[object Object],[object Object]

CAFE standards ,[object Object]

Drilling in ANWR will not fill U.S. oil demand

Personal choice and efficiency ,[object Object],[object Object],[object Object],[object Object],[object Object]

We already have the technology needed ,[object Object],[object Object],[object Object]

Efficiency among consumer products ,[object Object],[object Object],[object Object]

Conservation and renewable energy is needed ,[object Object],[object Object],[object Object],[object Object]

Conclusion ,[object Object],[object Object],[object Object],[object Object],[object Object]

QUESTION: Review ,[object Object],[object Object],[object Object],[object Object],[object Object]

QUESTION: Weighing the Issues ,[object Object],[object Object],[object Object],[object Object],[object Object]

QUESTION: Interpreting Graphs and Data ,[object Object],a) Extremely significant b) E x t r e m e l y in s i g n i f i c a n t c) Very high d) Worth drilling for

QUESTION: Interpreting Graphs and Data ,[object Object],[object Object],[object Object],[object Object],[object Object]
