World Peak CoalStudy Concludes “Peak Coal” Will Occur Close to 2011

2 August 2010

A multi-Hubbert analysis of coal production by Tadeusz Patzek at The University of Texas at Austin and Gregory Croft at the University of California, Berkeley concludes that the global peak of coal production from existing coalfields will occur close to the year 2011.

After 2011, the production rates of coal and CO2 decline, reaching 1990 levels by the year 2037, and reaching 50% of the peak value in the year 2047. It is unlikely that future mines will reverse the trend predicted in this business-as-usual (BAU) scenario, according to the study, which was published in the journal Energy.

EROEI

To Replace Non-Renewable Energy with Renewable Energy

• Produce 100 square meters of photovoltaic cells every second for 25 years

• Install 50 square meters of mirrors for solar thermal every second for 25 years

• Build one 3-megawatt wind turbine (100 meter diameter) every 5 minutes for next 25 years

What is needed to achieve this?• Build a 3 gigawatt nuclear plant every week for the

next 25 years (US has 8-10 planned for next decade)

• Bring a 300 MW steam turbine on line (for geothermal) every day for the next 25 years.

• For biofuels, fill an olympic sized swimming pool with genetically engineered algae every second for the next 25 years. This would be approximately like covering Wyoming with the algae.

An Effort equivalent to Retooling for WWII

• GM and Ford combined could make 1 wind turbine every 5 minutes

• Nokia, Intel, AMD, Apple could produce the necessary photovoltaic cells

• Coke and Pepsi in 10 years could make enough solar thermal mirrors using the aluminum that would be used for cans to produce 2 TW of power.

• Necessary land area for all of this would be the 7th largest country in the world (between Australia and India).

Nuclear Fusion

• Combining nuclei of smaller atoms to make larger atoms, thereby releasing energy.

• This is what happens with stars• No radioactive or carbon waste.• Potentially 20 or more years from being

viable

Nuclear FusionThe NIF & Photon Science Principal Directorate is one of five directorates at Lawrence Livermore National Laboratory (LLNL) in Livermore, California. The directorate operates the National Ignition Facility (NIF), the world´s largest and highest–energy laser, which has the goal of achieving nuclear fusion and energy gain in the laboratory for the first time – in essence, creating a miniature star on Earth.

The Keystone Generation needs to understand the current situation and develop solutions. This requires mathematical knowledge of which Algebra is the base.

Other, more personal motivators

• You chose to attend college to gain knowledge. • The ability to reason quantitatively is critical in our

technological world.• Getting a job to support your family is very

competitive. What would make someone hire a person with insufficient mathematical skills or work ethic when there are plenty of people with the skills and willingness to work?

Other, more personal motivators

• Algebra skills are assumed knowledge in college math classes.

• Consider that if you don’t work hard and learn the concepts this time, you will have to pay for the class again and eventually work hard enough to be successful anyway.
