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.
