Hallo steemians, how are you today? hopefully stay healthy. This time I want to explain a little about energy.
In physics, energy can be defined as the ability to do business. Can not be denied, all living things can not live without energy. The sun is a major source of life. All the energy sources used by living things in activity are essentially from the sun. In plants, the sun is used in the process of photosynthesis. According to the science of biology, photosynthesis is the process of converting solar light energy into chemical energy and storing it in the form of glucose (sugar or carbohydrates). In the process of photosynthesis the energy changes that occur are carbon dioxide and water is converted into oxygen glucose with the help of sunlight and chlorophyll. The overall chemical reactions involved in photosynthesis are:
For humans, the sun is also a major source of energy. The sun is used as a solar power plant. Solar power plant is one solution to save energy. Solar power plants are power plants that convert solar energy into electrical energy. Power generation can be done in two ways, namely directly using photovoltaic and indirectly with the concentration of solar energy.
Solar cells or photovoltaic cells are devices that convert light energy into electrical energy using photoelectric effects. Photovoltaics converts light energy directly into electricity using photoelectric effects. The concentration of solar energy using a lens or mirror system is combined with a tracking system to focus solar energy to a point to move the engine of heat.
How the Solar Cells works ?
What are the advantages of using electricity with solar panels?
- Reduced long-term electricity costs
- Reduce dependence on electricity from coal
- Avoid the impact of blackout when having to pursue deadlines, while the computer can not be turned on :-)
- Also reduces global warming because the solar panel system produces environmentally friendly energy that does not cause pollution.
Why Solar Cells?
- The majority of electricity used in Indonesia comes from power plants with coal raw materials. This process emits a lot of carbon emissions which is the biggest source of the cause of global warming (global warming). Certainly very dangerous, is not it?
- Our demand for electricity is getting bigger. See how many tools in our house can not run without electricity, from lights, mobile phones, television, air conditioning and refrigerators. Not to mention the wasteful use of electricity. As a result, our power plant is no longer able to provide electricity as big as its demand, so that power outages are becoming more frequent.
- On the other hand, Indonesia is a sun-rich country that is proven geographically Indonesia's location on the Equator as well as the Tropical Country. Therefore, it is great if we use sunlight as a source of energy.
