SOURCES OF USEFUL ENERGY - Coggle Diagram
SOURCES OF USEFUL ENERGY
-
NUCLEAR FUELS
-
-
WORKS
nuclear-fission of uranium fuel creates heat which can be used to produce steam for the generation of electricity
-
-
SOLAR POWER (LIGHT)
SUITABILITY
generation of electrical energy; solar power "farms"; domestic and commercial solar panels for buildings → lower power uses, e.g. calculators/chargers
-
-
-
WIND POWER
-
-
-
CONS
only generates electricity when wind blows over a threshold value - not as reliable and predictable as other sources
-
-
WAVE POWER
-
-
WORKS
moving water due to waves turning a generator that transfers a store of kinetic energy into electricity
-
TIDAL POWER
-
-
-
WORKS
moving water due to tidal currents turns a generator that transfers a store of kinetic energy to electricity
HYDRO-ELECTRIC POWER
-
-
WORKS
moving water stored behind a dam is channeled through pipes to generators that transfers a store of kinetic energy into electricity OR micro-scale generation in a river
CONS
construction of dam floods a river valley destroying wildlife habitats and sometimes human settlements
-
GEOTHERMAL SOURCES
-
-
WORKS
hot water from natural hot springs can be used to generate steam for production of electricity OR water for heating is pumped down to depth, heated and then pumped back to the surface
-
BIOMASS
SUITABILITY
large and small scale production of crops (e.g. wood) for burning in power stations OR for the production of biofuels
-
WORKS
fast-growing wood is harvested and made into pallets which are burned in power stations OR crops are decomposed by microorganisms to produce biofuels
