Trang 1Current situation of energy
resources in the world
Trang 2How many types of energy in
the world?
Energy is mainly divided into two categories: renewable and non renewable.
Non-renewable energy is fossil energy sources such as coal, oil and natural gas, shale and oil sands
Trang 3Fossil fuel: coal…
Anthracite Bituminous coal
has 24,72% of human energy is through the use of coal
Trang 4Fossil fuel :Oil and natural gas
has 41.76% of human energy is through the use of oil Also use the rate of energy from natural gas is 21.16%
Trang 5Status of non-renewable energy
sources Our population increased rapidly
We have used fossil fuels than 50,000
times the speed they are being
We will not exist in a near future.
we need to find new energy sources to
replace them, is the eternal source of
energy.
.Renewable energy resources are gradually being replaced as:
Trang 6Nuclear Energy
Nuclear power plants to ensure supply of energy 6.25%
but the source of the cost to produce it was great
and its impact also left a strong influence on the
environment
Trang 7
water power
Hydropower plants provide energy 6.11%.
External power supply,
we also maintain a supply of irrigation
water for living.
Trang 8Solar energy
They are being used quite widely not affect the general environment
and should be used more
Trang 9Wind energy
is also one of the source energy clean quality but not use of many world
Trang 10Biomass Energy
Trang 11Geothermal energy
Trang 12Tidal energy
Trang 13• Saving energy will give us significant benefits of
economic recession by reducing the exploitation and "save" the precious resource for future generations
• Find and expand the use of renewable resources is also essential
