Earth’s Energy Endowment
Earth’s Energy Flows
• Solar flow• Tidal flow • Geothermal flow
Also Energy is stored in• Fossil fuels• Nuclear fuels
Solar Energy
• Solar energy is the radiant light and heat from the Sun.
• It is a renewable energy source.
Geothermal energy Geothermal energy is heat from within
the earth. Geothermal energy is a renewable energy source.
Tidal energy or Tidal power
Tidal energy is created by the relative motion of the Earth, Moon, Sun, and the gravitational interactions between them.
Fossil Fuels
.
oil Coal Gas
Fossil Fuels are hydrocarbons. they have been formed from the organic remains of prehistoric plants and animals.
Three major fossil fuels are :
How do fossil fuels form?
Fossil Fuel Use 86 % of global energy consumption is
fossil fuel.
Fossil Fuel Uses
Nuclear FuelsNuclear power is generated using Uranium, which is a metal mined in various parts of the world. It is a non-renewable energy resource.
Wind power
Variation of pressure between areas caused by solar energy, causes wind effect. Wind power is a renewable source.
Biomass
Wood and dry crop wastes are referred to as biomass derived fuels. Plants use photosynthesis, deriving the energy from the sun.
