stove

washing machine

hairdryer

video recorder

coal oil natural gas

wind(power) sun(solar energy)

water(hydro-electric power)

the sea ( tidal energy)

uranium(nuclear energy) plant waster(biomass energy) T: Now let’s look at some more pictures and decide whether they are renewable or

not. (Slide show: pictures of some forms of energy) wind energy

non-renewable (picture) uranium Ore (铀矿石) non-renewable (picture) The element uranium does not occur in pure form in nature but is

found in minerals such as carnotite（钒钾铀矿）,

pictured above. (picture) Conclusion non-renewable coal oil natural gas

Uranium

fossil fuels renewable wind (wind power) sun (solar energy) water (hydro-electric power) plant waste (biomass energy) hot springs or geysers (geothermal energy) the sea (tidal energy) Slide show What are fossil fuels? Ancient animal and plant material below the surface of the earth with a high carbon content, such as coal, oil and natural gas, which can be burnt to produce energy.

Also known as non-renewable energy because once they are used they have gone
