Common clean energy sources include:
1. Tidal energy
Tidal energy (tidal energy) is the energy contained in the periodic rise and fall of sea water. The difference in water level is expressed as potential energy and the speed of the current is expressed in kinetic energy. Both types of energy can be used and are a form of renewable energy. Because tides are the most reliable and regular among the various movements of seawater, and because they move up and down the shore, they are also the first to be recognized and used by humans. Among the various uses of ocean energy is the use of tides. the energy is the most mature.
2. Solar Energy
Solar energy refers to thermal radiation energy from the sun (see the three modes of thermal energy transmission: radiation). Its pmain manifestation is often called). solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters. Since the birth of life on earth, it has relied primarily on thermal radiation energy provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method of making food, such as crafting. salt and dry the salted fish.
As fossil fuels decline, solar energy has become a significant part of human energy consumption and continues to grow. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy in the broad sense also includes wind energy, chemical energy, energyie hydraulics, etc. on earth.
3. Wind energy
Wind energy is the kinetic energy generated by air flow. A converted form of solar energy. Due to the uneven heating of various parts of the earth's surface caused by solar radiation, the pressure distribution in the atmosphere is unbalanced. Under the action of the horizontal pressure gradient, the air moves in the horizontal direction to form wind. The total reserves of wind resources are very huge, and the technically developable energy in one year is approximately 5.3 x 10^13 kilowatt hours.
Wind energy is a renewable and clean energy with large reserves and wide distribution. However, its energy density is low (only 1/800 of the energy of water) and unstable. Under certain technical conditions, wind energy can be developed and used as an important energy source. The use of energyWind turbine is a comprehensive engineering technology that converts the kinetic energy of wind into mechanical, electrical and thermal energy through wind turbines.
IV. Hydrogen energy
Hydrogen energy is the energy released by hydrogen during physical and chemical changes. Hydrogen energy is the chemical energy of hydrogen which mainly appears in the form of chemical compounds on earth. It is the most widespread substance in the universe. It constitutes 75% of the mass of the universe and is a secondary energy source.
There are many ways to produce hydrogen in industry. The most common include electrolysis of water to produce hydrogen, gasification of coal to produce hydrogen, steam catalytic conversion of heavy oil and natural gas to produce hydrogen, etc. . consume more energy than they produce.
5. Bioenergy
EnergyBiomass is the energy provided by living plants in nature. These power plants use biomass as a means of storing solar energy. It is a renewable energy source. It is estimated that the energy stored in biomass amounts to 27 billion kilowatts, double the current global energy consumption. The first energy used in human history was biomass energy. Before the second half of the 19th century, the energy used by humans wasFirewood was the main source.

1. How to play in Hong Kong Ocean Park Strategy Video
Hong. Kong Ocean Park water parks require special tickets. Ocean Park in Hong Kong is free, but all Ocean Park activities require separate tickets. For example, the Hong Kong Park water park requires special tickets. Visitors enterrant in Hong Kong Ocean Park water park do not need to purchase this ticket.
2. How to get to Hong Kong Ocean Park
: 930629 recommends. The walking distance is short. Walk from the hotel to Sha Tsui Road and take bus No. 930 directly across the sea to Admiralty Unity Center Pier. Bus number 629 serves Ocean Park directly.
3. How long does it take to visit Ocean Park Hong Kong
Ocean Park Hongkong is located in Wong Chuk Hang, South District, Hong Kong Island, China, covering an area of over 91.5 hectares. It opened on January 10, 1977. It is a world-class theme park integrating marine animals, mobile games and large-scale shows. It is also the most popular theme park in the world with the largest number of visitors.
The park is built on the mountain and is divided into two major attractions, namely the Peak Paradise and the Seaside Paradise, which are connected by a cable car and an ocean train. In 2012, Ocean Park Hong Kong won the 2012 Applause Award, the highest honor awarded by the International Association of Amusement Parks and Attraction Exhibitions (IAAPA), becoming the first theme park in Asia to win this honor.

It is recommended to visit Hong Kong Ocean Park.
Hong Kong Ocean Park, surrounded by mountains and sea, has an aquarium and a theme park. It is mainly divided into two parts: the seaside park at the foot of the mountain and the summit park on the mountain. Connected by the sea-view cable car, it is divided into eight themed areas, including Asian Animal World, Fantasy Water, Pico World and Ocean World.
There are three means of transportation, namely cable car, ocean train and climbing elevator. The cable car is a means ofe popular transportation and you can enjoy the beautiful scenery of southern Hong Kong Island and the South China Sea, but many people queue. The Ocean Train is a two-way, very fast cable car. It only takes three minutes from Waterfront Park to Peak Park. The Mountaineering Lift is the second longest open-air escalator in Hong Kong, connecting Ocean World and Rapids World, with a total length of 225m. It is recommended to take the ocean train to climb the mountain. To go down the mountain, take the cable car first, then the cable car. Generally speaking, there are more queues when you take the cable car up the mountain, which not only saves time, but also allows you to experience the three modes of transportation.
From 2010 to 2012, there were ten theme parks in Hong Kong, including Hong Kong Disneyland, Noah's Ark Theme Park, Snoopy World and more.other fun theme parks in Hong Kong, as well as Hong Kong Ocean Park, etc. Marine theme parks, science theme parks such as Hong Kong Astronomical Park, aviation theme parks such as Kai Tak Runway Park, cultural and historical theme parks such as Kowloon Walled City Park, Hong Kong Zoological and Botanical Gardens, Ma Wan Park, Tsuen Wan Park and other specialty parks in Hong Kong.
