The energy resources used to generate electricity can be divided into two categories: nonrenewable and renewable.
Слайд 2

The energy resources used to generate electricity can be divided into two categories: nonrenewable and renewable.

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 3

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.

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 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.

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.

Nuclear Power. Nuclear power plants use the heat from splitting atoms to convert water into the steam that turns turbines.
Слайд 6

Nuclear Power

Nuclear power plants use the heat from splitting atoms to convert water into the steam that turns turbines.

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 7

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.

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. The word "geothermal" comes from the Greek words geo, for earth, and therme, for heat. So geothermal means "earth heat."
Слайд 9

Geothermal Energy

The word "geothermal" comes from the Greek words geo, for earth, and therme, for heat. So geothermal means "earth heat."

Geothermal energy is steam (or hot water that has been converted to steam) from deep inside the earth.
Слайд 10

Geothermal energy is steam (or hot water that has been converted to steam) from deep inside the earth.

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 11

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.

Hydropower. Hydroelectric plants use the power of falling water to turn the turbines that help generate electricity.
Слайд 12

Hydropower

Hydroelectric plants use the power of falling water to turn the turbines that help generate electricity.

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 13

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.

The world's first wave power station is on the Scottish island of Islay. It generates enough electricity for about 400 homes.
Слайд 14

Solar Energy. Solar energy is generated without a turbine or electromagnet..
Слайд 15

Solar Energy

Solar energy is generated without a turbine or electromagnet..

Special panels of solar cells, or modules, can capture sunlight and convert it directly into electricity
Слайд 16

Wind Power. Wind power is renewable energy that uses the force of the wind to spin turbines. These spinning turbines generate electricity.
Слайд 17

Wind Power

Wind power is renewable energy that uses the force of the wind to spin turbines. These spinning turbines generate electricity.

A very large wind farm can generate enough electricity for all the homes in a city of about one million people.

Советы как сделать хороший доклад презентации или проекта

  1. Постарайтесь вовлечь аудиторию в рассказ, настройте взаимодействие с аудиторией с помощью наводящих вопросов, игровой части, не бойтесь пошутить и искренне улыбнуться (где это уместно).
  2. Старайтесь объяснять слайд своими словами, добавлять дополнительные интересные факты, не нужно просто читать информацию со слайдов, ее аудитория может прочитать и сама.
  3. Не нужно перегружать слайды Вашего проекта текстовыми блоками, больше иллюстраций и минимум текста позволят лучше донести информацию и привлечь внимание. На слайде должна быть только ключевая информация, остальное лучше рассказать слушателям устно.
  4. Текст должен быть хорошо читаемым, иначе аудитория не сможет увидеть подаваемую информацию, будет сильно отвлекаться от рассказа, пытаясь хоть что-то разобрать, или вовсе утратит весь интерес. Для этого нужно правильно подобрать шрифт, учитывая, где и как будет происходить трансляция презентации, а также правильно подобрать сочетание фона и текста.
  5. Важно провести репетицию Вашего доклада, продумать, как Вы поздороваетесь с аудиторией, что скажете первым, как закончите презентацию. Все приходит с опытом.
  6. Правильно подберите наряд, т.к. одежда докладчика также играет большую роль в восприятии его выступления.
  7. Старайтесь говорить уверенно, плавно и связно.
  8. Старайтесь получить удовольствие от выступления, тогда Вы сможете быть более непринужденным и будете меньше волноваться.
