Q.1 Classify the various energy resources and explain each of them.

Renewable energy resources are derived from sources that are naturally replenished on a human timescale. These resources are generally considered sustainable and environmentally friendly because they produce little to no greenhouse gas emissions during energy generation.

a. Solar Energy: Solar energy is derived from the sun's radiation. It can be captured using solar panels (photovoltaic cells) to convert sunlight directly into electricity or through solar thermal systems that use sunlight to heat a fluid to generate electricity.

b. Wind Energy: Wind energy is harnessed by wind turbines, which convert the kinetic energy of the wind into mechanical power. This mechanical power is then converted into electricity through a generator.

c. Hydropower: Hydropower utilizes the energy of flowing water, typically from rivers or dams, to generate electricity. Water flows through turbines, causing them to rotate and generate electricity.

d. Biomass Energy: Biomass energy is derived from organic materials such as wood, agricultural residues, and organic waste. It can be used directly as fuel or converted into biofuels like ethanol and biodiesel.

e. Geothermal Energy: Geothermal energy is produced by harnessing heat from the Earth's interior. This heat can be used directly for heating buildings or generating electricity through geothermal power plants.

f. Tidal Energy: Tidal energy is generated by harnessing the kinetic energy of tidal currents. Tidal turbines are placed underwater to capture the energy from the ebb and flow of tides.

Non-Renewable Energy Resources:

Non-renewable energy resources are finite and will eventually be depleted. They are primarily fossil fuels formed from organic materials over millions of years.

a. Coal: Coal is a combustible black or brownish-black sedimentary rock formed from fossilized plant matter. It is burned to generate electricity and is also used in industrial processes such as steel production.

b. Petroleum (Oil): Petroleum is a liquid fossil fuel composed of hydrocarbons. It is refined into various fuels such as gasoline, diesel, and jet fuel, as well as used in the production of plastics and chemicals.

c. Natural Gas: Natural gas is a fossil fuel primarily composed of methane. It is used for heating, cooking, and electricity generation, as well as in industrial processes and transportation.

d. Nuclear Energy: Nuclear energy is generated from the splitting (fission) or fusion of atomic nuclei. Fission reactions are used in nuclear power plants to generate heat, which is then converted into electricity through steam turbines.

Each of these energy resources has its advantages and disadvantages in terms of availability, environmental impact, reliability, and cost. The shift towards renewable energy sources is driven by concerns about climate change, energy security, and sustainability.

Q.2 What is coal extraction? Classify coal extraction and explain the classifications.

Q.3 Describe the steps involved in the process of petroleum refining.

Q.4 Compare the nuclear fusion and fission process in detail.

Q.5 Describe briefly the different forms of renewable energy.

Q.6 Discuss in detail the environmental impact of fossil fuels.

Q.7 Describe the collector-cum-storage solar water heater in detail.

Q.8 Discuss in detail a wind-solar hybrid system.

Q.9 What are the various types of digester? Explain, in detail.

Q.10 Explain the principle of geothermal energy working, usage and technological aspects.
