Question

compare and contrast fossil fuels and the sun as direct source of energy

Answer 1

$\pink{\underline{{\bf\huge Answer : }}}$

$\red{★}$ ғᴏssɪʟ ғᴏᴜʟ :-

$\implies\sf$Fossil fuels are energy sources, such as coal and petroleum, obtained from underneath the Earth's crust.

$\implies\sf$They are directly available to human beings for use. Hence, fossil fuels are the direct source of energy. These are limited in amount.

These are non-renewable sources of energy because these cannot be replenished in nature.

$\implies\sf$Fossil fuels take millions of years for their formation. If the present fossil fuel of the Earth gets exhausted, its formation will take several years. Fossil fuels are also very costly.

$\red{★}$ sᴏʟᴀʀ ᴇɴᴇʀɢʏ ;-

$\implies\sf$On the other hand, solar energy is a renewable and direct source of energy. The Sun has been shining for several years and will do so for the next five billion years. Solar energy is available free of cost to all in unlimited amount. It replenishes in the Sun itself.

$\red{★}$ ᴡʜᴀᴛ ɪs ᴀ ғᴏssɪʟ ғᴏᴜʟ?

$\implies\sf$a natural fuel such as coal or oil, that was formed millions of years ago from dead animals or plants in the ground.

$\green{★}$ ɪɴ ʜɪɴᴅɪ :-

$\implies\sf$कोयला या तेल जैसे प्राकृतिक इंधन जिनका निर्माण लाखों वर्ष पहले ज़मीन में दबे मृत पशुओं या पौधों से हुआ; पुराकालीन ईंधन।

$\red{★}$ ᴡʜᴀᴛ ɪs sᴏʟᴀʀ ᴇɴᴇʀɢʏ?

$\implies\sf$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, molten salt power plants and artificial photosynthesis.

$\green{★}$ ɪɴ ʜɪɴᴅɪ :-

$\implies\sf$सामान्य रूप से सौर ऊर्जा को सूर्य से प्राप्त किरणों से परिवर्तित करके बनाया जाता है। सूर्य से जो ऊर्जा प्राप्त होती है उसे विद्युत ऊर्जा में बदलना ही सौर ऊर्जा कहा जाता है। इसका उपयोग बड़े-बड़े कारख़ानों में कई तरह के कार्यों को करने के लिए किया जाता है।
