2. Energy Security Energy Security Energy Choices depend on…
The ability to secure affordable, reliable and sufficient energy supplies for the needs of a particular country
Can be a tough choice for nations (Do you buy foreign of produce domestically?)
Energy Choices depend on…
Availability of supply
Technological Developments
Politics
Economics
Cultural Attitudes
Sustainability
Environment
Economic Prosperity will always require energy, but no matter what we do, what will eventually happen to nonrenewable energy resources?

3. Energy Choice Examples
Ukraine-Russia
Initially Russia exported gas to Ukraine for a low cost
In 2006 Russia felt this relationship was being abused and cut supplies
Secure?
USA Shale Oil
“Tight Oil”: stuck in rocks and too expensive to get out
But…new tech…high oil prices…since 2008 US tight oil production has increased from 6x10^5 to 3.5x10^6 barrels a day.
Could turn the USA from a net importer to an exporter
Wind Turbines in Denmark
Produces over 30% of energy from wind
Linked to neighboring countries so Denmark can buy or sell if needed

4. Energy Resources All energy comes from the SUN!!!!! Fossil Fuels
We just don’t always rely on obtaining it through plants/photosynthesis
Fossil Fuels
Stored solar energy
Non –renewable
Compressed, decomposed remains of life from millions of years ago
Emit CO2 when burned
When will we run out of fossil fuels?
Coal: 230 years
Natural Gas: 170 years
Oil: 100 years
But what if the rate at which we use them increases?

5. Energy Resources

6. Fossil Fuels and CO2 Emissions
CO2 emissions per unit of energy produced for various energy resources.

7. Energy Consumption
We continue to use non-renewable fuels at an increasing rate
Oil Prices peaked in 2008 at $145 per barrel. (How much today?)
The EU produces less tan 7% of its energy from renewables.
Future?
Hydrogen economy?
Fusion?
Renewables?
