Слайд 2
Описание слайда:
The energy resources used to generate electricity can be divided into two categories:
nonrenewable
and
renewable.
Слайд 3
Описание слайда:
Nonrenewable resources cannot be increased. We can make these supplies last longer by using them wisely, but when they are gone we will not have any more.
Слайд 4
![The majority of electricity used in the world is generated at power plants that burn fossil fuels to heat water and make steam. The steam is highly pressurized and directed at turbine ['tɜbaɪn] blades to make them spin.](/documents_2/5577aab924621419395bbf25f4c7d6b7/img3.jpg)
Описание слайда:
The majority of electricity used in the world is generated at power plants that burn fossil fuels to heat water and make steam. The steam is highly pressurized and directed at turbine ['tɜbaɪn] blades to make them spin.
Слайд 5
Описание слайда:
The three forms of fossil fuels are
coal,
oil, and
natural gas.
They are known as fossil fuels because they were formed from the fossilized remains of animals or plants that lived long ago.
Слайд 6
Описание слайда:
Nuclear Power
Nuclear power plants use the heat from splitting atoms to convert water into the steam that turns turbines.
Слайд 7
Описание слайда:
Renewable Resources
Renewable energy resources can be replenished in a short period of time, so they will never be all used up. Energy companies all over the world are using renewable resources more and more to generate electricity.
Слайд 8
Описание слайда:
Biomass
Biomass is organic matter, such as agricultural wastes, and wood chips and bark left over when lumber is produced. Biomass can be burned to heat water to make steam, which turns a turbine to make electricity. It can also be converted into a gas, which can be burned to do the same thing.

Geothermal Energy
Слайд 10
Слайд 11
Описание слайда:
Hydrogen
Hydrogen is a colorless, odorless gas. Hydrogen can be converted into electricity through a chemical reaction in a device called a fuel cell. Converting hydrogen into electricity produces no pollution—only water and heat.
Слайд 12
Описание слайда:
Hydropower
Hydroelectric plants use the power of falling water to turn the turbines that help generate electricity.
Слайд 13
Описание слайда:
Wave power
The energy of the ocean's waves and tides can also be used to generate electricity with dams that force ocean water through turbines. This is called tidal energy, or wave power.
Слайд 14
Описание слайда:
The world's first wave power station is on the Scottish island of Islay. It generates enough electricity for about 400 homes.
Слайд 15
Описание слайда:
Solar Energy
Solar energy is generated without a turbine or electromagnet..
Слайд 16
Слайд 17
Описание слайда:
Wind Power
Wind power is renewable energy that uses the force of the wind to spin turbines. These spinning turbines generate electricity.
