slide1

Natural Resources

Perpetual

Renewable

Non-renewable

slide2

Natural Resources

Perpetual: Available forever

(in “human time” perspective)

Perpetual energy sources?

Solar Radiation

Wind

Tides

Rivers (hydro)? perhaps...

slide3

Natural Resources

Renewable: Rate of replenishment by natural processes ≥ Rate of consumption

Renewable energy sources?

Wood*

Other biomass*

*but there’s a catch...

slide4

Natural Resources

Non-renewable: Rate of replenishment

by natural processes < Rate of consumption

Non-renewable energy sources?

Oil

Natural Gas

Coal

Nuclear

Geothermal -- a “tweener”

slide5

Sustainable

Able to continue a certain behavior

indefinitely.

Sustainable Yield

The maximum rate at which humans can use a resource over a long time period (i.e., without reducing the possible level of yield).

slide6

Renewable(e.g. timber/wood, water, clean air, fisheries, etc.)

Perpetual(but not in danger of

being used unsustainably)

What class(es) of natural resources could be used sustainably?
