  1. Energy Resources

  2. Nonrenewable Energy

  3. COAL • Coal currently provides 40% of the world’s electricity needs. • Second source of primary energy in the world after oil • Estimated to be enough coal to last another 112 years

  4. PETROLEUM • The world uses about 26,000,000,000 barrels of petroleum every year. • At this rate, there should be enough oil for at least another 40 years. • Oil companies are always searching for new oil fields more will probably be discovered

  5. NATURAL GAS • Proved reserves of natural gas, expected to last until 2060 (46 years) at the present extraction rate. • Probable reserves are reserves discovered in deposits that show high probability of being extractable. • Potential reserves include so-called unconventional sources, that have a low potential of being extractable

  6. NUCLEAR • estimated on the planet's economically accessible uranium resources, reactors could run more than 250 years at current rates of consumption. • Waste from reactors lasts 200 – 500 thousand years

  7. Renewable Energy

  8. BIOMASS • Biomass (plant material and animal waste) is the oldest source of renewable energy. • Beneficial biomass sources generally maintain or even increase the stocks of carbon stored in soil or plants. • Energy Crops • Manure • Crop Residues • Forest Residues • Urban Waste

  9. SOLAR • Radiant light and heat from the sun • harnessed using a range of ever-evolving technologies • solar heating • solar photovoltaics • solar thermal electricity • solar architecture • artificial photosynthesis

  10. GEOTHERMAL • heat from the Earth • It's clean and sustainable • Resources of geothermal energy • shallow ground • hot water and hot rock found a few miles beneath the Earth's surface • extremely high temperatures of molten rock called magma.

  11. WATER • derived from the energy of falling water and running water, • hydro-power has been used for • irrigation • operation of various mechanical devices, • Watermills • Sawmills • textile mills • dock cranes • domestic lifts • power houses • Tidal power: form of hydropower that converts the energy of tides

  12. WIND • conversion of wind energy into a useful form of energy • wind turbines to make electrical power • windmills for mechanical power • windpumps for water pumping or drainage • sails to propel ships.
