  1. High Energy Society Why do we care about energy?

  2. 61 of 73 I am very energy conscious. What do you think?

  3. What is Energy • We will look at the precise physics definition in a bit, but essentially, it is the ability to make something move. • The rate of using energy is called POWER. Something that is powerful uses a lot of energy quickly.

  4. What do we care about energy? • The bottom line is that using energy is strongly correlated to standard of living (as measured by GDP per capita). • For most of history, we could rely on our own bodies (about 100 W) or animals to do work.

  5. Today in the US, we consume energy at a rate of 11 kW per person.

  6. The vehicle I most like to drive or want to drive on a regular basis is…

  10. Earth at Night – Energy Use

  11. Energy use is directly tied to GDP The GDP of a country is defined as the market value of all final goods and services produced within a country in a year. It is also considered the sum of value added at every stage of production of all final goods and services produced within a country in a given period of time. GDP = consumption + investment + (government spending) + (exports − imports)

  12. GDP versus Energy Usage GDP per capita (US $)

  13. China is the World’s Biggest Consumer of Energy

  14. US Per Capita Energy Use

  15. We are doing better ona GDP per kWh basis. Energy Intensity is a measure of the energy efficiency of a nation's economy. It is calculated as units of energy per unit of GDP. * High energy intensities indicate a high price or cost of converting energy into GDP. * Low energy intensity indicates a lower price or cost of converting energy into GDP.

  16. How Large is a Quadrillion BTU? It's about equal to the amount of energy in 45 million tons of coal, or 1 trillion cubic feet of natural gas, or 170 million barrels of crude oil. In 2010, total world energy consumption was about 1 quad every 25 hours. In terms of electricity, 1 quad is equal to 293 gigawatt-hours.
