Here are a few solar energy facts to aid in your evaluation of solar energy’s capacity to satisfy world demand.
The first fact is that solar energy is a plentiful, cost-free source of energy. Even though the sun is 90 million miles away from the planet, light can traverse that distance in less than 10 minutes.
Fact 2: Modern technology such as sustainable development goals cells, solar heating, artificial photosynthesis, solar architecture, and solar thermal power can be used to capture solar energy, which is made up of radiant heat and light from the sun.
Fact 3: There are two types of solar technology: active and passive. Examples of active solar technology include solar thermal collectors and photovoltaic panels, which use solar energy. Construction of spaces with better air circulation and space orientation to make the most of sunlight are examples of passive technology.
Fact 4: In the upper atmosphere, the earth receives 174 Petawatts of solar energy. The remaining 30% is absorbed by seas, clouds, and land masses, while around 30% is reflected in space.
Fact 5: Solar insulation has sustainable development goals and effects on the water cycle. As a result of absorbing solar energy, the earth, oceans, and atmosphere warm up. Convection is brought on by warm air rising from the oceans. Clouds are produced when this air reaches high elevations and water vapor condenses. The water cycle is finished when these clouds produce rain, which returns water to the earth’s surface.
Fact 6: Solar power has yet another application. Green plants use photosynthesis to transform solar energy into chemical energy, which results in the biomass that goes into making fossil fuels.
Fact 7: Agriculture and horticulture aim to utilize solar energy as much as possible. These include methods like synchronizing planting cycles and blending different plant species. Additionally, light is converted into heat in greenhouses to support the year-round production of specialty crops.
Fact 8: Sun-powered hot water systems heat water using solar energy. In SDGs sustainable development goals in some regions, solar heating can provide 60 to 70 percent of the domestic water needed for temperatures as high as 60 degrees Celsius.
Fact 9: Passive solar ventilation systems include solar chimneys. The building’s interior and outside are connected by shafts. Utilizing thermal mass materials and glazing can improve functionality.
Fact 10: Potable, brackish, or salt water can also be created using solar energy. Wastewater can be treated without the use of electricity or chemical agents. One of the earliest use of solar energy is the production of salt from saltwater.
Fact 11: You can use clotheslines, fabric racks, etc. to dry your SDGs sustainable development goals outside in the sun.
Fact 12: Solar energy can be used to cook, dry, or pasteurize food.
Fact 13: The most intriguing application of solar energy is solar power. It is the process of turning solar energy directly into electricity using photovoltaics or concentrated solar power (indirect). In the case of concentrated solar power, large solar beams are focused into a narrow beam using mirrors or lenses.
