renewable resources
resources that can be replaced such as trees are known as…
nonrenewable resources

  • resources that cannot be replace and are gone forever
  • examples include fossil fuels, natural gas, coal, petroleum

coal, natural gas, petroleum
name 3 types of of fossil fuels
fossil fuels

  • sources of energy that is depleted quickly
  • inexpensive to manufacture/use
  • used to produce electricity
  • takes a long time to form
  • buring it causes pollution

what is this?

inexhaustible resources

  • a type of resource that can be used over and over
  • examples include wind, ocean waves, biomass, geothermal, water, solar

geothermal energy

  • earth’s internal heart
  • hot water and steam coming out of the ground (geysers)
  • used to heat homes/produce energy
  • used in California

disadvantage: only in areas where the earth’s heat rises to the surface

hydroelectricity
the potential energy of water trapped behind dams is called…
biomass

  • corn/other grains used with gas to run cars
  • use plant matter/animal waste to form fuel
  • minimum environmental impact
  • expensive and difficult to produce

disadvantage:carbon dioxide and greenhouse gases is created which is harmful to the environment

solar

  • an inexhaustible resource
  • expensive to produce
  • use with sun to produce energy

wind

  • have turbines that rotate blades to convert kinetic energy into electrical energy
  • almost no polution is produced

disadvantage: loud noise, need lots of land, some birds can get killed by the turbine’s propellers

reduce, reuse, and recycle
3 ways to conserve resources would be to…
