Non conventional sources of energy

Difference between Conventional and Non Conventional Energy can be defined as the capacity or ability to do work. It plays an important role in our day to day life as it is required in every field like industry, transport, communication, sports, defence, household, agriculture and more. There are plenty of energy sources to get energy. These energy resources can be classified as Conventional and Non-conventional sources of energy. Let us see how they differ from each other! Conventional sources of energy: Conventional sources of energy are the natural energy resources which are present in a limited quantity and are being used for a long time. They are called non-renewable sources as once they are depleted, they cannot be generated at the speed which can sustain its consumption rate. They are formed from decaying matter over hundreds of millions of years. These resources have been depleted to a great extent due to their continuous exploitation. It is believed that the deposits of petroleum in our country will be exhausted within few decades and the coal reserves can last for a hundred more years. Some common examples of conventional sources of energy include coal, petroleum, natural gas and electricity. Non-conventional sources of energy: Non-conventional sources of energy are the energy sources which are continuously replenished by natural processes. These cannot be exhausted easily, can be generated constantly so can be used again and again, e.g. solar energy, wind energy...

Patterns of Use Globally, fossil fuels supply 81% of primary energy. 1 In 2021, 79% of U.S. primary energy consumption came from fossil fuels. 2 Conventional and unconventional fossil fuels differ in their geologic locations and accessibility; conventional fuels are often found in discrete, easily accessible reservoirs, while unconventional fuels are found in pore spaces throughout a wide geologic formation, requiring advanced extraction techniques. 3 If unconventional oil resources (oil shale, oil sands, extra heavy oil, and natural bitumen) are accounted for, the global oil reserves quadruple current conventional reserves. 4 The price of crude oil peaked in 2008 at $145.31 per barrel, making unconventional fossil fuels more cost-competitive. 5 However, in 2020, the price of crude oil temporarily fell below zero. 5 Partially as a result of sustained low oil prices, over 250 oil and gas producers have filed for bankruptcy since 2015. 6 The Energy Policy Act of 2005 includes provisions to promote U.S. oil sands, oil shale, and unconventional natural gas development. 7 Global Projected Liquid Fuel Production 8 Major Unconventional Sources Unconventional Natural Gas • Unconventional natural gas (UG) comes primarily from three sources: shale gas found in low-permeability shale formations; tight gas found in low-permeability sandstone and carbonate reservoirs; and coalbed methane (CBM) found in coal seams. 9 • Although several countries have begun producing UG, many global reso...

Energy is a key component for most of the consumption activities and production activities and hence plays a vital role in a country’s economic growth and development. It is essential for industries and is now widely utilised in agriculture and related fields such as the manufacture and delivery of fertilisers, insecticides, and farm equipment. It is also required in homes for cooking, lighting, and warmth. Based on the sources from which energy is derived, it can be classified into two categories; viz., Conventional Sources of Energy and Non-Conventional Sources of Energy. Conventional Sources of Energy The sources of energy which are in use for long and can be stored are known as Conventional Sources of Energy. These are non-renewable sources of energy. For example, coal, natural gas, electricity, thermal power, cow dung, straw, etc. Even in the present times, many industries use coal and oil. Commercial and Non-commercial Sources of Energy are known as Conventional Sources of Energy. Non-conventional Sources of Energy The sources of energy which have only recently come into use are known as Non-conventional Sources of Energy. These sources are renewable sources of energy. For example, wind energy, solar energy, bio-gas, tidal power, and geo-thermal energy. As India is a tropical country, its potential to produce non-conventional sources of energy is almost unlimited. Although it is possible if the already available appropriate cost-effective technologies are used. Howev...

With reference to two non-conventional energy sources called ‘coal bed methane’ and ‘shale gas’, consider the following ‘statements: • Coal bed methane is the pure methane gas extracted from coal seams, while shale gas is a mixture of propane and butane only that can be extracted from fine-grained sedimentary rocks. • In India abundant coal bed methane sources exist, but so far no shale gas sources have been found. Which of the statements given above is/are correct? • 1 only • 2 only • Both 1 and 2 • Neither 1 nor 2 CBM = Methane Shale gas = Lot of Methane + Little Ethane, Propane, & Butane + very little carbon dioxide, nitrogen, and hydrogen sulfide. Abundant shale reserves occur in India. Fuel Production Advantages Limitations Nuclear energy Nuclear fission (splitting of atom) and Nuclear fusion • No • Fuel efficient • High cost of construction of nuclear plant. • Fear of security and nuclear accidents. • Problem of safe disposal of nuclear waste. Hydropower Dams built on river for electricity generation • World’s hydroelectricity capacity high • Ecosystems behind dams disturbed. • Human settlements up rooted. • • Developmental cost high. • Fertile farmland lost • Amount of nutrient rich silt on down river agricultural fields reduced. Solar energy From natural sunlight • Environment friendly • Ample or unlimited availability. • Limited capacity for storage of sunlight. • Cloud cover. • Collecting equipment expensive.

Conventional and Non-conventional Sources of Energy Energy is the ability of a physical system to perform work. We use energy in our daily lives from various sources for doing work. We use muscular energy for carrying out physical work, electrical energy for running multiple appliances, chemical energy for cooking food, etc. For this, we need to know the different energy sources to obtain energy in its usable form. This article will familiarize you with two important sources of energy: conventional energy and non-conventional energy. Table of Contents • • • • • • • • • • • • • Coal Coal is the most important source of energy. There are more than 148790 coal deposits in India, and between 2005-2006, the annual production went up to 343 million tons. India is the fourth-largest coal-producing country, and the deposits are primarily found in Bihar, Orissa, Madhya Pradesh, Jharkhand and Bengal. Oil and Natural Gas Oil is considered liquid gold and one of the crucial energy sources in India and the world. Oil is primarily used in planes, automobiles, trains and ships. The total oil production in India was 0.3 million tons in 1950-51, which increased up to 32.4 million tons in 2000-01. It is mainly found in Assam, Gujarat and Mumbai. Electricity Electricity is a common form of energy used for domestic and commercial purposes, and it is mainly utilized in electrical appliances like fridges, T.V, washing machines and air conditioning. The major sources of power generation are: • N...

Source Of Energy What is Energy? Before learning about sources of energy, let’s understand what energy is. Classical description for energy is the ability of a system to perform work but because energy exists in so many forms, it is hard to find one comprehensive definition. In short, energy is the ability of a system to make things happen. It is a property of an object which can be transferred from object to object or converted to different forms but cannot be created or destroyed. There are numerous sources of energy. It can be chemical energy, electrical energy, heat/ thermal energy, mechanical energy, nuclear energy and energy in the form of Sources of energy contain energy in them in forms that cannot be used directly but living organisms require energy to stay alive. Therefore you must unlock this energy to get work done. Humans get energy from food which has this energy stored in the form of chemical energy. Your body absorbs this energy from food and burns it to fuel your body so that you can run around and have fun. A candle has a lot of chemical energy but it has to burn for it to be useful. This conversion of chemical energy to yield heat and light energy is burning. Burning is a process of converting chemical energy to heat energy and sometimes light too. We must make one observation though, energy seems to have a shelf life. If you keep a hot object out in the open, it will cool after a while. Can you collect this energy back from the atmosphere? You will le...
