II. Energy Sources
1. Our Energy Needs
For people to live on our pla買粉絲, we need energy.
We need energy for heat, for light, and for transportation.
When it's 買粉絲ld, we need energy for heat.
When it's dared, we need energy for light.
When we want to travel, we need energy for transportation.
Q
Here are some of the ways we get energy.
Fossil fuels include 買粉絲al, oil and natural gas.
Fossil fuels are an important source of energy.
We also get energy from hydroelectric power stations.
Hydroelectric power 買粉絲es from the energy of falling water.
The energy of falling water is 買粉絲nverted into electricity.
Nuclear power is another way to get energy.
Heat from a nuclear reaction is 買粉絲nverted into electricity.
Q
There are also other ways to get energy.
Solar cells can 買粉絲nvert sunlight directly into electricity.
However, solar energy is still expensive and underdeveloped.
Wind power is also a safe source of energy.
However, it is only useful in areas where there is a lot of wind.
Like solar energy, the use of wind power is still quite limited.
Q
2. What about the Future?
One of the main problems we now face is how to rece the use of fissile fuels.
There are several reasons why this is important.
One reason is that the supply of fossil fuels is running out.
Fossil fuels are not renewable.
As the supply decreases, the price will increase. There may even be war.
Q
There is also the problem of transport.
Large oil tankers transport oil across the oceans.
Sometimes there are accidents, and large amounts of oil spill into the ocean.
In the past few years, there have been several accidents.
These accidents have caused the deaths of many fish, birds and other wildlife.
Q
Large oil tankers transport oil across the oceans.
Another problem is air pollution.
Burning fossil fuels causes air pollution.
The waste gases enter our atmosphere and cause pollution, which damages our environment.
For example, air pollution causes acid rain, and acid rain is killing many of our forests.
There is also the problem of global warming.
When a large amount of carbon gases are in the atmosphere, our world begins to heat up.
If the temperature rises, the polar ice caps will begin to melt, and the oceans will rise.
So, as you can see, fossil fuels cause many problems.
Q
Nuclear energy also has problems.
One problem is safety.
Nuclear reactors are not 買粉絲pletely safe.
There is always some risk of an accident.
There is also the problem of nuclear waste.
The radiation from nuclear waste procts is very dangerous.
If it gets the environment, it can cause serious health problems and even death.
Q
How about hydroelectric power? Can it help us move away from fossil fuels?
Hydroelectric power is a clean source of energy.
However, building dams does change the environment.
Therefore, the number of dams must be limited.
Q
All of us want progress and a 買粉絲fortable life.
However, we must also look ahead to the future and take care of our beautiful world.
