5.2 Renewable Energy Resources Study Guide

Renewable resources are NOT wisely managed when

• the government passes laws to encourage their use 
• people buy products that are made with these resources
• people do not use them whenever it is possible to do so

The disadvantage of water-

• energy plants are far from urban areas
• energy can be affected by drought
• energy is its negative impact on aquatic ecosystems

Wind, water, geothermal-

•  energy are non-polluting, but large-scale use of these resources is limited to certain areas
• energy use is that it is limited to certain times of the day
• less energy efficient than fossil fuels

The best sites for wind-

•  energy plants are far from urban areas 
• cities

Disadvantage of solar-

• energy is its negative impact on aquatic ecosystems 
• energy is that it is less energy efficient than fossil fuels
• energy use is that it is limited to certain times of the day

A disadvantage of hydroelectric power is

• energy use is that it is limited certain times of the day
• it can harm fish and other organisms
• nuclear energy produces radioactive wastes
  

Disadvantage of using biomass energy-

• it is less energy efficient than fossil fuels
  
• it can harm fish and other organisms
• energy is its negative impact on aquatic ecosystems
  

The availability of using water-

• energy can be affected by drought  a process in which mined land is recovered with soil and replanted with vegetation
• energy are non-polluting, but large-scale use of these resources is limited to certain areas
  
• energy are non-polluting, but large-scale use of these resources is limited to certain areas

The disadvantage of using nuclear energy-

• energy is its negative impact on aquatic ecosystems
• nuclear energy produces radioactive wastes
• nuclear energy produces radioactive wastes
  

________________  is NOT a renewable energy resource

• The sun
• Natural gas 
• moving water
