Two sources of Energy on Earth Topic 1: The Origin of Oil

Solar energy drives: Wind, photosynthesis, ocean thermal energy, hydrologic cycle. Fossil fuel = stored solar energy. Energy sourced by accretion of the Earth system: Geothermal, tides, presence of fissionable elements BIG ENERGY FLUX SMALL ENERGY FLUX/SOURCE Two sources of Energy on Earth Topic 1: The Origin of Oil

Power versus Energy Topic 1: The Origin of Oil Power = energy per unit time 1 Watt= 1 kg m /s 3 = 1 Joule/s Energy = kWh (kiloWatt hour)
4
Power Provided From the Sun 340 watts/m 2 (Power of sunlight per square meter) x (area of all continents) 170 watts/m 2 x 148 x 10 12 m 2 = 25,000 TW Global Energy Consumption is about 12 TW Earth’s stored + radioactive heat= 44 TW

The rest (over half) is used to make things like:

Fossil fuel has made energy cheap! Power = energy per unit time 1 Watt= 1 kg m /s 3 = 1 Joule/s Energy = kW h (kiloWatt hour) Work by one person 50 W x 24 hrs 1000 Wh or ~1 KWh/day Topic 2: What makes Oil so Special?
9
1 KWh per day is about what’s required to keep a 100 W light bulb going for 10 hours. We pay about 32¢ per KWh for electricity on Oahu - so we get the equivalent energy of a hard-working person for 32¢ per day. 1 “Barrel of oil equivalent (BOE)” = 1700 KWh or 1700 days or 1700 x 20= 34,000 hrs of hard human labor.

10 The expansion of human civilization is strongly linked to access to cheap, high-quality energy sources. My Birthday 1967
11
Modern agriculture requires more than ten units of fossil fuel energy for every unit of energy eaten. Take away fossil fuels, and productivity will decrease greatly. “Soil is the catalyst used to turn oil into food.”
12
About 85% of our food and staples come to Hawaii on ships that burn oil. The average North American meal travels 1,500 miles before it gets to your plate.
13
In 2010 about 80% of Hawaii’s electricity is generated from oil. Today its about 70%. In 5 yrs we’ve added about 10% of energy from renewables!
