Green Energy for Today and Tomorrow
Did you know that most of the energy we use comes from the sun? For example, the sun helps plants to grow. Plants that grew millions of years ago turned into coal, oil, and natural gas(天然气). We call these fossil fuels(化石燃料).
However, fossil fuels cause pollution. This is bad for the Earth. Fossil fuels are also nonrenewable. Some day they will be gone. So, scientists want people to use green energy.
Why is green energy important? First, it is clean. It doesn't hurt the Earth. Next, it is renewable. It won't run out. Green energy gives us almost 25% of the electricity we use today.
What are the main sources(来源) of green energy?
Water Power
Water power uses moving water in rivers and dams(堤坝). Moving water has energy. Water power makes
16.6% of the electricity we use.
Wind Power
Is wind power new? No, it isn't. People used wind power many years ago. Wind power makes 4% of the electricity we use.
Solar Power
Solar power comes from sunlight. The sun shines on solar panels(太阳能电池板), and electricity is made. Solar power is now as cheap as some fossil fuels. It makes
1.5% of the electricity we use.
Biomass energy(生物质能)
Biomass energy is energy that we get from plants around us. For example, dead wood or grass is burned in power stations. This makes electricity. Biomass energy is green energy because we plant new trees or crops(庄稼) after we use it. Biomass energy makes 2% of the electricity we use.
New Green Energy
The ocean rises and falls each day. This moving water can make electricity. We call it tide power. There is also heat under the Earth's surface. Scientists can use this heat for energy, which is called heat power. We may find other sources of green energy in the future.
Some day, green energy could make 100% of the electricity we use. That's good news for the Earth!
Travel Squad--Travel Like A Soldier Recently, "travel squad' (特种兵式旅游) becomes a popular trip style in China. It means travel like a soldier. It's different from the relaxing kind of traveling that we all know. Visitors often go to a lot of places in a short period of time at a low cost, usually on weekends. Most of these them are college students. "Such a trip can bring a different color to my stressful life." said Chen, a 24-year-old university student. "Because it is very energy-consuming (耗体力), it is not suitable for everyone." she added. ▲ The city of Pontevedra in Spain is great for walking and cycling. People can't drive in the city center. They make 73 percent of journeys in the city on foot or by bike. Only 30 percent of the public space is for cars. Seventy percent is for people. From 2001 to now, there are no deadly road accidents, and the CO2 level went down by 67 percent since the 1990s. Fun and Fitness on Bikes A cyclist dresses up during a 16-kilometer bike ride in Moscow during the spring 2023 Velofest. Velofest is a big cycling activity in Russia. The activity was a celebration in support of bike culture and healthy lifestyles. A number of people took part and many dressed up. It meant that they want an active lifestyle and eco-friendly (环保的) way of traveling. |
