Types of Resources
|
-Renewable: wind, water, all manner of vegetation.
-Recyclable: metals and most other natural resources. -Non-Renewable: fossil fuels. |
|
Solutions
|
-Innovation: popular; expensive; time-consuming. Not applicable???
-Conservation: not popular; implies sacrifice; |
|
Pre-Industrial
|
-Land: muscle
-Sea: wind, muscle -Air: muscle or wind -Energy/Heat: wood, coal (gradually); muscle wind water. -Problems: time-consuming; low energy production; low level of economic development. |
|
Industrial
|
-Land: oil, electricity.
-Sea: oil -Air: oil -Energy/Heat: coal; nuclear; gas; oil; hydro -Problems: will run out; carbon emissions; political risks |
|
The Future
|
-Land: maybe electric, biofuels, solar.
-Sea: electric—no, Maybe biofuels. Nuclear, sail, solar. -Air: biofuels, not electric. -Energy/Heat: nuclear, etc. Wind, solar. Hydro. -Problems: complexity, cost. |
|
The Bottom Line
|
-Current Energy Economy: cheap and fungible energy sources (globalization rulz).
-Future Energy Economy: non-fungible energy sources; possibly more expensive. -Danger: sustainablity of economic growth over time; breakdown of globalization???. |
|
Nuclear
|
-Energy Potential: yes
-Technological Maturity: yes -Fuel Supply: several centuries. -Fuel Supply Reliability: yes -Greenhouse Gases?: no -Produces Liquid Fuel?: no -Environmental Issues: safety and waste. High political risk. -Cost: start-up and operation |
|
Wind and Solar
|
-Energy Potential: huge
-Fuel Supply: inexhaustible. -Technological Maturity: not -Fuel Supply Reliability: geographic and seasonal variations. Implies a global energy grid. -Greenhouse Gases?: no -Produces Liquid Fuel?: no -Environmental Issues: kills birds; noise pollution; very land-intensive. Relies on batteries. -Cost: yes |
|
Hydro
|
-Energy Potential: no
-Fuel Supply: dammable river. -Technological Maturity: already dammed. -Fuel Supply Reliability: yes -Greenhouse Gases?: no -Produces Liquid Fuel?: no -Environmental Issues: displacement of population; kills fish. -Cost: high fixed. |
|
Geothermal
|
-Energy Potential: huge
-Fuel Supply: inexhaustible. -Fuel Supply Reliability: yes, but access problems. -Greenhouse Gases?: no -Produces Liquid Fuel?: no -Technological Maturity: access problems. -Environmental Issues: none? -Cost: very high. |
|
Bio-Fuels
|
-Energy Potential: very high
-Fuel Supply: land, or other source of biomass. -Technological Maturity: low -Fuel Supply Reliability: very weather-sensitive. -Greenhouse Gases?: carbon-neutral. -Produces Liquid Fuel?:yes -Environmental Issues: forest cut-downs—no longer carbon-neutral…; choice of fuel vs. food; much greater use of energy. -Cost: still high |
|
Encouraging Innovation
|
-Market pressures: yes but: possibly too late.
-Government incentives: bad choices. |
|
Benefits of High Gas Prices
|
-Gov’t revenue
-Less use |
|
US Oil Habit
|
Reasons: pop density; hegemony; oil production.
|
|
