Sun is the largest source of energy in the world, and has various benefits for the life of living things on Earth.
According to the Big Indonesian Dictionary (KBBI), the sun is a star which is the center of the solar system, emitting heat and light to the Earth and other planets that orbit it, most of which are hydrogen and helium.
So, what exactly is solar energy and what are its uses? Check out this short review below.
Benefits of Solar Energy
Collect sunenergy.idSolar energy is energy that is produced from radiant heat from the sun. As one of the largest sources of energy on earth, the sun’s heat is able to support the survival of all living things.
It can be said, that the energy emitted by the sun provides great benefits for life on Earth, both for short-term and long-term needs.
As the main source of energy for the life of living things on Earth, the sun is very beneficial for all aspects of life. Here are the various benefits of solar energy for humans and living things on Earth.
1. Benefits of Solar Energy for Humans
Unlike other energy sources, the sun is an energy source that has no limits and is included in the category of renewable energy. The existence of solar energy provides a myriad of benefits for humans, including:
- As a source of vitamin D, which is needed by the human body.
- As a power source. Utilization of solar energy as a source of electricity is carried out through solar power plants (PLTS).
- Provide natural lighting for humans.
- Burn fat in the body, so it is indirectly able to lose weight.
- Acts as a photoreceptor, which is able to relieve pain and relieve pain stress. Research shows that sun exposure makes people feel more comfortable and less stressed.
- Can maximize the body’s metabolic function.
- Cure certain skin disorders.
Those are some of the benefits of solar energy for humans. Keep in mind, some of these benefits are obtained with a record of the body receiving reasonable exposure to solar energy. Too long exposure to the sun actually has a negative effect on the body.
Because sunlight consists of various types of radiation, ranging from cosmic rays, gamma rays, X-rays (X-Ray), ultra violet (UV). These UV rays include UVC, UVB and UVA rays.
Types of harmful radiation, such as cosmic rays, gamma rays, X-Ray and UVC are indeed filtered by the atmosphere. However, other types of radiation such as UVB, UVA, and infrared rays reach the earth’s surface and affect the human body.
If the body is exposed to the sun for too long, then the negative effects that can arise are, sunburn, increase skin aging and increase the risk of skin cancer. Therefore, it is highly recommended not to be exposed to the sun for too long. Experts advise, long sunbathing without sunscreen (sunscreen) is 20 minutes
2. Benefits of Solar Energy for Animals
As already mentioned, solar energy provides benefits for life on Earth, including for animals. Some of the benefits of solar energy for animals include:
- Warms the animal’s body in order to survive. This is especially true for reptiles such as crocodiles, snakes and lizards.
- As a source of vitamin D. Just like humans, animals also need vitamin D and the sun is a natural source to get this vitamin intake.
- Some animals take advantage of the heat from the sun to help facilitate the digestion of food.
- Keeping the animal’s body temperature warm and stable.
- The sun helps the process of photosynthesis of plants which are a source of food for animals.
- Helping the growth of the animal’s body to be faster.
- Some animals need sunlight to speed up the adaptation process of animals to their environment.
- As a source of information for finding prey and food.
- As a signpost for flying animals.
- Regulate sleep cycles.
3. Benefits of Solar Energy for Plants
For plants, solar energy is one of the most needed energy sources, besides water. Some of the benefits of solar energy for plants include:
- Helps the process of photosynthesis which is useful for producing food for plants.
- Helps the process of plant growth as a whole.
- As the best source of nutrients for plants.
- Maintain plant temperature to be more stable and balanced.
- Warms seeds in plants.
- Activates chlorophyll contained in plants.
- Gives a green color to the plant.
- Helping the growth of flowers and leaves, plants exposed to sunlight will quickly flower and grow tall.
- Help the sprout growth process to become richer in nutrients.
Thus the benefits of solar energy for humans, animals and plants. It can be concluded, that the existence of the sun is indeed essential for the Earth, because without it there is no life on Earth.
Without the sun, the Earth’s temperature would not allow it to be lived, even by bacteria. If the sun suddenly did not emit its rays, then the Earth’s temperature would drop drastically.
Earth’s temperature will not drop to 0 degrees Celsius.0C) instantaneously, because the Earth is still storing heat from solar radiation from the time / time when the sun is still emitting its rays. It takes a very long time for the Earth’s temperature to drop to 0 0C. However, during that time the cycle of life on Earth will be disrupted until it is finally destroyed before the Earth’s temperature reaches zero.
The reason is, the absence of sunlight will cause plants to be unable to carry out the photosynthesis process, which converts carbon dioxide and water into oxygen and glucose. If the sun stops shining, the photosynthesis process will stop. As a result, plants cannot produce the glucose or oxygen that animals and humans need.
In conclusion, if the sun does not shine, then slowly but surely, life on Earth will be destroyed. Both because of the extreme drop in temperature, and because of the death of plants which are a source of oxygen and food.
