Lesson 4.3

RENEWABLE vs. NON-RENEWABLE

Renewable Energy Sources

HYDRO
NUCLEAR
SOLAR
BIOMASS
GEOTHERMAL
WIND
Biomass

How power is generated:

  • combustion (burning) of materials - same as coal
Environmental problems:
  • deforestation
  • CO2, plus air pollutants
Human health problems:
  • air pollutants (carbon monoxide, nitrogen oxides, particulates) can cause respiratory problems

Geothermal Energy

How power is generated:

  • steam released from hot aquifers is used to turn turbines
Environmental problems:
  • groundwater depletion
  • release of H2S (hydrogen sulfide) can cause acid rain
Human health problems:
  • airborne hydrogen sulfide can cause respiratory issues

Geothermal can heat homes, too.

Nuclear Power

How power is generated:

  • nuclear fission (U235)
  • energy heats water to turn turbine
Environmental problems:
  • accidents/spills
  • thermal pollution
  • no fully safe way to dispose of spent fuel rods
Human health problems:
  • thyroid cancer, leukemia, birth defects, radiation poisoning

Hydroelectricity

How power is generated:

  • water spins turbines in dams
Environmental problems:
  • evaporation
  • habitat alteration
  • sediment buildup behind dam
Human health problems:
  • Reservoirs of water can be breeding grounds for mosquitos

TIDAL/WAVE ENERGY

Solar (Photovoltaic)

How power is generated:

  • Photovoltaic (PV) cells capture light energy from the sun and transform it directly ito electrical energy
Environmental problems:
  • localized significant temperature increase, particularly in desert ecosystems
Human health problems:
  • None

Renewable
Non-Renewable

Nonrenewable energy sources are those that exist in a fixed amount and involve energy transformation that cannot be easily replaced.

Renewable energy sources are those that can be replenished naturally, at or near the rate of consumption, and reused.

Wind

How power is generated:

  • blades spin turbines directly
Environmental problems:
  • birds and bats can collide with blades
Human health problems:
  • none, though some people report noise issues with turbines nearby

Passive Solar
Active Solar

Passive solar is a home/building design strategy that aims to maximize the sun's rays in the winter for heat and reflect them in the summer.

Active uses solar collectors on roof (water or air) and then a pump to move heat through house. (Ex: Solar water heater)
