A （词数：281；易读数：76）
Energy is everywhere. We use energy every day.
Electricity is a form of energy and this is what powers the TV, hair dryer, phone, fridge, electric toothbrush and more! Our growing need for energy is one of the problems that the world is facing today, because producing electricity also produces pollution.
Here are some ways to make a big difference when we are using electricity.
On or off Leaving televisions and computers off with the little red light on still uses electricity, even though they might look like they’re turned off. To stop this you can turn them off.
Lights out! Turning lights off when you are not in the room can save a lot of energy. If you stay in the room, use natural light whenever possible. Moreover, you can use energy-efficient light bulbs. LED bulbs use less energy and last longer than traditional bulbs.
Fridge doors closed. The fridge is an important part of the kitchen, because it keeps food fresh, cool and healthy! But it takes a lot of energy to keep cool, so try not to leave the fridge door open or put hot things inside.
Use the Sun’s energy. An increasing number of people are using solar panels in their houses. They produce electricity from sunlight, which can then be used to power their homes. Solar heating panels make hot water, reducing the need for electricity or gas.
By following these tips, you can save electricity and reduce your energy bills.

Cars make our lives more convenient. But they can also be a problem. For example, fossil fuel cars mainly cause air pollution.
To improve the environment, many countries are developing electric vehicles. Among them, China is taking a leading role and has created the world’s largest EV(electric vehicle) market.
Last year, over 40 percent of the 753,000 EVs sold in the world were sold in China, more than twice as many as the number sold in the United States.
“Filling up a fossil fuel car with gasoline is more expensive than charging an electric car,” said Wu Hao, who bought an electric car this year.
As the prices of fuel and oil continue going up, the electric cars will become more and more popular in people’s life. Electric cars are different from normal cars. They work by batteries. The battery affects how far the car can go. An electric car can go from 50 to 250 miles. It costs less than the normal car. According to a report, when a normal car goes a mile, one has to spend about 12 cents on it. But for an electric car, it only needs about two cents. It saves lots of money.
However, there are still some problems. It can be hard to find charging piles and the cars can’t go far before recharged. Hopefully, Some of these problems are being solved. In 2014, China had about 31,000 charging piles. Now China has the world’s largest EV charging network, with more than 167,000 charging piles in total.
Developing EVs is one of many efforts that China has made to cut down pressure on its environment after the government promised to stop increases in carbon dioxide emissions by 2030.
“As China goes, so will the world’s car industry,” The Wall Street Journal said. China has taken a leading role in the world’s electric vehicle industry.
