The most important alternate energy source is flowing water, harnessed as hydroelectric power. Other sources include the Ocean’s tides and waves, wind power (harnessed by windmills and wind turbines) the Sun (Solar energy) and the heat trapped in the Earth’s Crust (geothermal energy). Renewable Resource: -
þ Describe the sources and effects of heat. þ Explain thermal expansion of solids, liquids and gases. þ Explore the effects and applications of expansion and contraction of solids.
thermal energy, gravitational energy, electromagnetic-radiation energy, chemical energy, and nuclear energy, have been defined to explain all known natural phenomena.
distinguish between renewable and non-renewable sources of energy; describe various types of sources of energy e.g. fossil fuels, water, wind, biomass, sea, geothermal, nuclear energy; recognise that the sun is the ultimate source of energy; explain the advantages and disadvantages of different sources of energy;
