Tide is the regular rise and fall of the ocean level caused by the movement of the sun, the earth and the moon. It is considered a promising source of green energy to produce electricity in coastal areas.
To make use of tidal energy, we need to build tidal power stations. The bays* and the river mouths where the tide is high (the tidal range is more than 10 metres) are usually perfect sites to build tidal power stations. There are many such places in the world. According to the IRENA (the International Renewable Energy Agency), by just using 2% of our coastlines, we can produce 4, 383TWh of ocean power each year, enough to meet 16. 4% of the world's electricity needs.
To build a tidal power station, we need to build a dam. In the dam are many turbines and on each turbine there is an electric generator*. When the tide rises, water comes through the dam, the turbines turn and the electric generators work, producing electricity. When the tide fall, water goes out through the dam, the turbines turn again. The electric generators continue to work.
Tidal energy has it advantages. Using tidal energy to produce electricity is much cheaper than using the traditional energy, like coal or gas. For example, the Rance Tidal Power Station in France has been there for over 50 years, producing around 540, 000TWh of electricity each year. The cost is only 1.3 cents/TWh. Tidal energy can be used nearly 24 hours a day. As long as the sun, the earth and the moon exist, we can use it to produce electricity. But without sunshine, here is no solar energy. When there is no wind, electric generators will not work In addition, with the development of modern technology, tidal energy can be stored and used to produce electricity continuously. However, we still have some problems to solve. It is difficult to build a dam in the sea, and the cost is very high. Moreover, it's expensive to keep a tidal power station in is best condition.
Scientists are working on them.

Harbin, a city in the northeast of China, drew greatattention and became the hottest tourist city last winter. In fact, on January 5th every year, the city of Harbin innortheast China{#blank#}1{#/blank#} into a winter wonderland. Tourists from all around the world come to visit the {#blank#}2{#/blank#} ice and snow festival.
The festival started in 1963 and began as a winter party. The festival often lasts for one month. However, if the weather stays cold and dry, it will {#blank#}3{#/blank#} for a few more days. Temperatures are usually very low. They can go down to -17℃. Ice sculptors (雕塑家) use different tools to shape the hard ice and snow. These sculptors show their works in two main areas. "Sun Island" has huge snow sculptures of people and animals. "Ice and Snow World" has sculptures of buildings. At night, these buildings light up {#blank#}4{#/blank#} brightly-colored lights. Visitors can do a lot of other {#blank#}5{#/blank#}, such as skiing and ice sliding. They can also go swimming in the icy waters of the Songhua River.
