Alternate energy source: Solar Energy
Solar energy is one of most popular energy sources around the world. this is because it us conveniently to obtainable, as well as space efficient. It doesn’t take up a lot space and give superb energy. The sun is one of the most reliable energy sources on this planet. This is because the sun has been predicted to stay “alive” for many million years to come. It’s radiation also does not fluctuate from day to day like other sources of energy. Solar energy is most commonly harvested through solar panels that are usually faced so that they receive the most optimal sunlight. There are many uses for solar energy. Solar power is run on the radiation from the sun. This is a good thing because the total solar energy absorbed by Earth is nearly 3,850,000 exajoules (EJ) per year. This includes the atmosphere, the ocean and the land masses that cover the earth’s surface. The applications of solar energy are as follow: Architecture and Urban Planning | One of the simplest ways to acquire solar energy. This is because it relies on the infrastructure of the building. Architectures today are offering a “solar design” option to clients, where the building can be made to receive optimal sun radiation to get solar lighting and heating. The ventilation system would be designed to compliment this system. Using this system can potentially reduce temperature by nearly 3 °C at an estimated cost of US$1 billion, giving estimated total annual benefits of US$530 million from reduced air-conditioning costs and healthcare savings. | Agriculture and horticulture | Solar energy plays a very important role in this category because plants need sunlight to survive. Applications of solar energy in agriculture aside from growing crops include pumping water, drying crops, brooding chicks and drying chicken manure. For specialty plants, a greenhouse is the best option. This is because these building, not only provide the plants
