Sort of Renewable Energy

Photovoltaic Energy Generation
Photovoltaic energy refers to light energy coming from the sun, and refers to energy using solar cells that convert solar light energy into electrical energy using photoelectric effect. It is a more advanced way in solar power technology that uses solar heat directly for heating. Solar power generation is a way of generating electricity by converting sunlight into direct current. Solar power uses solar panels with several solar cells attached. As demand for renewable energy increases, production of solar cells and photovoltaic arrays is increasing.

Tidal Barrage Generation
The principle of tidal barrage generation is generally to turn the generator by closing the floodgate and then opening the door, using the force of water spilling. The fall is usually less than 10m, smaller than the fall from the hydraulic power. There are only a limited number of countries that have tidal resources because the tidal difference is only available in large areas with large capacity reserves. In particular, Korea's west coast has various sizes of bight, and due to its large geographical features, it is considered a good place to develop tidal energy. Tidal power is a clean energy source with low power costs and no pollutants. In addition, they are in the spotlight because their energy sources are unlimited and infinite. Its major advantage is that it can produce electricity twice a day without being affected by weather conditions. It is the only renewable energy source that can be predicted over the long term. That's because tide phenomenon is a regular and accurate long-term forecast because it is caused by regular celestial movements.

Biomass Energy Generation
Bioenergy is energy that uses biomass. Biomass is the most used energy source in the world until the 19th century, when trees were the main energy source. Currently, about 10 percent of the world's primary energy consumption comes from biomass. When biomass is heated with a small amount of oxygen, a medium gas is produced. The gas can be purified and used to produce heat and electricity through a cogeneration generator. If biomass is heated to a high temperature of 500°C with the air completely cut off, heat decomposition occurs. Heat decomposition produces bio oil, gas, and charcoal, which is used to produce electricity and heat, and charcoal is used to fuel

Wind Energy Generation
Wind energy is the energy used to convert the kinetic energy of a natural wind into rotating energy and eventually produce electricity. Wind power is a form of solar energy that can produce electricity through wind turbines. Wind power is unlimited and clean energy that is pollution-free. The amount of wind energy is determined by the length of the rotor blades and the speed of the wind, and the larger the diameter of the wing, the higher the wind velocity, the greater the electrical production is possible. The cost of installation and maintenance is lower than other renewable energy sources, and facilities such as windmills can also be used for tourism. However, if the wind is thin, the development is difficult and a device is needed to store energy. Also, the noise from wind turbines can have a bad effect on the living things around them. To compensate for these shortcomings, large ocean wind farms have been increasing the efficiency of wind power generation.

Pros/Cons in the Field of Renewable Energy

"Chinese Juniper of Bomunsa Temple

Chinese junipers (Juniperus chinensis L.) can be found in the southern part of Korea, as well as in Ulleungdo Island and Japan. They have a strong scent and are therefore used as incense in ancestral rituals and commonly planted in gardens and parks.

This Chinese juniper, growing on the rock in front of the Grotto of Bomunsa Temple, is assumed to be about 700 years old. It was designated as Incheon Monument No. 17 in recognition of its biological value. It seemed to have withered during the Korean War (1950-1953), but revived itself three years later. It is 20 m in height and 3.2 m in circumference." ^[1]
