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. oilCoal 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 Fuels Nuclear 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.
Energy Resources Renewable and Non Renewable.
