There is no doubt that energy plays a crucial role in the development and progress of the national economy. In response to rapid industrialization, infrastructure expansion, population growth, as well as the expansion of the economy, there is a need for more sources of energy. Even so, conventional energy reserves have a finite lifespan and will only become available in a certain number of years with steadily increasing prices in the future. Additionally, the use of fossil fuels contributes to the development of environmental problems, particularly the global warming problem. Our current energy market presents us with an opportunity to reduce our dependence on fossil fuels by expanding and diversifying our energy supply mix. In addition, we can shift the development process towards sustainability as well as environmental and social responsibility in light of the challenges facing us today. 

1.1 Introduction The life on the earth is driven by the energy available in the various forms. Energy is the most crucial entity in development of the world. The sufficient and sustainable supply of energy is deciding factor in the global energy market. Solar energy from the sun is the basic source of energy on the earth which further manifest into the other energy forms. However, the fossil fuel energy is widely used energy on the larger scale on commercial basis due to its availability and technological advancement in handling these fossil fuels.

2.1 Energy Consumption Pattern and Energy Resources in India Energy is vital commodity in economic development of the world and any country. India also experienced a greater shift from non-commercial to commercial energy use after independence over the period. Industrialization and increased population has increased the consumption of commercial energy sources. The mechanization in agriculture and access to clean energy for household application also increased the consumption of the energy. however, the per capita energy consumption remains lower compared to the developed countries. In broader view, the energy used can be categorised in Non-commercial and Commercial energy sources that are used in India.

3.1 Introduction The sun emits electromagnetic radiation, which is referred to as solar radiation. Every location on the Earth’s surface receives some sunlight during the course of the year, but the amount of solar radiation varies. On a daily basis, we see much less energy from the sun than it emits and incident upon the earth. In an hour and a half, the amount of sunlight that reaches the surface of the earth is enough to provide enough energy for an entire year. 

4.1 Introduction The wind is caused by the motion of air. In different regions, there are pressure differences that cause winds. There is a tremendous amount of energy carried by them. The use of wind energy can be profitable in regions with strong winds for a significant part of the year. The wind is a form of solar energy. The wind is caused by uneven heating of air and land by the sun. The earth’s rotation and geological irregularities also play a role. Heating causes air to rise, and cooling causes cooler air to fall to fill the space. As a result, the air mass moves. On a global basis, the poles exert a primary forcing function that allows the equator to receive surface winds from the poles. 

5.1 Introduction Biomass energy is the energy obtained from biomass or living things. Biomass is renewable organic material that comes from plants and animals. Plants generally produced through the process of photosynthesis as shown in Figure 5.1. Biomass is organic, meaning it is made of material that comes from living things, such as plants and animals. Wood, plants, and waste are the most common biomass energy sources. These are called biomass feedstocks. A plant absorbs the sun’s energy through photosynthesis and converts carbon dioxide and water into nutrients (carbohydrates). The energy from these materials can be transformed into usable energy through direct and indirect means. Biomass can be burned to create heat (direct), converted into electricity (direct), or processed into biofuel (indirect).

6.1 Introduction Biomass pellets are one of the most common types of biomass fuel. It is generally composed of wood waste, agricultural biomass, grasses, and forest residues, and is one of the most popular types of biomass fuel available today. Pelletization of biomass results in significant savings in terms of transportation, and storage, as well as the ease of handling biomass as a whole. In terms of flowability, dense cube pellets are similar to cereal grains in terms of their characteristics of being dense and cube-shaped. Due to their regular geometry and small size, biomass pellets are easily fed through an automatic feed system with fine calibration thanks to their regular shape. Because pellets are so dense, they can be stored in a compact way and transported over a long distance in a rational and efficient manner, because of their density. Furthermore, pellets can also be produced with a low moisture content, even though they are extremely dense. This allows them to burn with a high degree of combustion efficiency due to their low moisture content.

7.1 Introduction A biodiesel fuel is an environmentally friendly, renewable, biodegradable fuel that is produced at domestic facilities from vegetable oils, animal fats, or recycled grease from restaurants. In accordance with the Renewable Fuel Standard, biodiesel meets the requirements for biomass-based diesel as well as the requirements for advanced biofuels as a whole. Biodiesel is distinct from renewable diesel, also known as “green diesel.” In its pure, unblended form, biodiesel is also known as B100 or neat biodiesel. Biodiesel is used to fuel compression-ignition engines in the same way as petroleum diesel. Alternatively, biodiesel is a liquid biofuel that can be used in diesel engines alone or blended with diesel oil. The fuel is obtained through the chemical conversion of vegetable oils or animal fats combined with alcohol.

8.1 Introduction Biogas is produced by the anaerobic digestion of biodegradable materials with the help of microorganisms. Biogas is also considered as renewable energy source because of is environment friendly nature. Conversion of cattle dung, kitchen wastes and agricultural wastes into biogas have the potential to minimize the burden on the fossil fuel and reduce the environmental pollution. Majority of developing countries specially their rural and suburban areas faces lack of access to the electricity and cooking gas. Biogas technology is emerging as a sustainable technology for waste treatment which could help to tackle the waste disposal issue in developing countries. 

9.1 Introduction Hydrogen is colourless and odourless gas. Hydrogen is simplest and lightest element and most abundant available element on the earth. It is not primary energy source as it does not exist in free state however it presents in compound with oxygen (water) and carbon, nitrogen and oxygen in living material and fossil fuels (natural gas, coal and biomass). Therefore, hydrogen can be produced from these sources using some external energy. Hydrogen can be burned without generating CO2 and have clean combustion. but with air it can form very explosive mixture. Hydrogen is considered as an energy carrier. Like energy carrier allows the transport of energy in usable form from one place to another. 

10.1 Introduction As one ofthe oldest and most widely used renewable energy sources, hydropower generates electricity by using the natural flow of flowing water. Streams and rivers have been used for producing mechanical energy for thousands of years. Hydroelectric power plants are located near or on water sources since they derive their power from flowing water. The amount of energy that can be released in moving water depends on the volume of the water flowing and the elevation change from one point to another, often called head. Generally, hydropower plants can produce more electricity when there is more water flow and a higher head. 

11.1 Introduction More than 70% of Earth’s surface is covered by the ocean, the world’s largest solar energy collector and storage system. By utilizing only a small portion of this energy, we can meet all the energy needs around the world. As long as the sun shines and there are natural ocean currents, Ocean Thermal Energy Conversion (OTEC) energy source is free, abundant, and continually replenished. It is estimated that 3 to 5 terawatts (1 terawatt is 1012 watts) of baseload power generation can be practically harvested without affecting ocean temperatures or the environment of the planet. this is about the twice the global demand for electricity. Oceans are therefore an abundant renewable resource, offering a sustainable method for the production of electricity in the future. 

12.1 Introduction A magneto hydrodynamic energy conversion system or MHD system converts heat energy directly into electricity. An MHD generator produces electricity via the interaction of a moving fluid with a magnetic field and ionized gas. MHD conversion does not involve any mechanical conversion intermediary. As a result, this process offers substantial fuel savings because the process of producing mechanical energy and then converting it to electrical energy is eliminated. It is possible to generate electricity in large quantities using MHD power plants while reducing the impact on the environment. During his Bakerian lecture in 1832 to the Royal Society, Michael Faraday presented the concept of MHD power generation for the very first time. 

13.1 Introduction At a national level, the agricultural sector is one of the major potential users of energy in the Indian context. Further, it is often highly dependent on the supply of electricity and fuel in order to function properly. The term “agriculture” refers to all on-farm activities required for farming, raising animals, and associated activities associated with farmers, growers, and entrepreneurs. Fuels such as petroleum and electricity are primarily used for the operation of pump sets and other operations. In the future, this may result in problems with supply and price. Moreover, India has relatively small reserves of crude oil and will eventually be forced to import more crude oil to make up for the lack of reserves. In order to save energy and money on the farm, farmers must identify opportunities for energy conservation on the farm in order to maximize energy efficiency.
