write a short note on solar energy in 200 words
Answers
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture and artificial photosynthesis.
It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.
The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575–49,837 exajoules (EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012

Answer:India is tropical country it has enormous possibility of trapping solar energy photovoltech technology convert sunlight directly into electricity full stop solar energy is fast becoming popular in rular and remote areas some big solar power plants are been established in different parts of India which will minimise the dependence ofruler households on firewood and dung cakes which in turn will contribute to environment conservation and adequate supply of manure in agriculture.
