  1. Caleb Strode A.P.E.S. January 2010 Matching Sources to Uses

  2. Energy Sources • Fossil Fuels • Oil • Coal • Gas • Hydroelectric • Nuclear Power • Renewable Energy • Wood • Solar • Wind • Geothermal

  3. Fossil Fuel Consumption • The use of fossil fuels increased in the 20th century. • Between 1986 and 2006, the worldwide annual growth rate was 2%. • Coal fueled the indust. rev. in the 18th and 19th centuries. • After the oil shocks of ‘73 and ‘79, when the price of oil increased from $5 to $45 per barrel, there was a shift away from oil.

  4. Hydroelectric Uses • The energy harnessed from the gravitational pull of falling water. • Worldwide consumption reached 816 GW • Worldwide annual growth rate is 8%. • In the western world, the construction of large hydro plants stagnated due to environmental concerns. • Micro hydro is a new trend that has negligible environmental impacts and opens up more locations for power generation

  5. Nuclear Powahhhh!!!! • Nuclear Power accounts for 6.3% of the world’s total primary energy supply. • There were 439 operational nuclear reactors worldwide, as of November 2007. • No US reactors currently exist, (primarily because of Chernobyl), but some are being developed. • If coal, gas or oil electric generators are replaced by nuclear power plants, they must be considered CO2 negative when a pound of recycled military plutonium or uranium can replace 3,000,000 pounds of coal energy.

  6. Renewable Energy • In 2004, renewable energy supplied around 7% of the world’s energy consumption. • The renewables sector has been growing significantly since the last years of the 20th century. • In 2005 the total new investment was estimated to have been 38 billion US dollars. • Germany and China led with investments of about $7 billion dollars each.
