What Is Non Conventional Sources Of Energy
Rachal Langwith
Conventional sources of energy are the ones that are commonly used, and generally non-renewable sources of energy, which are being used since a long time. Examples of conventional sources of energy include oil, natural gas, coal, biomass, and electricity. The fossil fuels oil, gas and coal, provide more than 85 percent of energy consumed in the World as well as in Turkey. Conventional resources provide two-thirds of the country's electricity and almost all transportation fuels. Though conventionally sourced energy may have a lower initial cost than non-traditional energy sources such as solar or geothermal, the world's reliance on fossil fuels presents many challenges, including environmental damage, securing supply and resources and lack of sustainability. It is also becoming increasingly difficult to discover and exploit their new deposits.
Because fossil fuels are so valuable and they are not found everywhere, international politics is very much involved in producing and distributing fossil fuels. The dynamic world of conventional energy (focusing on oil, gas and coal energy) is a critical piece of the world energy portfolio. Our focus will be on recent trends, and perspectives on the future of conventional energy and how business interests are evolving to meet the interests and needs of new energy economies.
Electricity is another conventional source of power, which is playing a barometer of a nation's economic well-being. Availability of abundant electricity means unrestricted growth of industries, transport and agriculture.
Thermal-electric power plants, hydro-electric power plants, and nuclear power plants supply most of the electrical energy used in the world. These three methods of producing electricity are often referred to as conventional energy sources. This means that they are the more traditional or more commonly used sources of electrical energy.
The selection of electricity production modes and their economic viability varies in accordance with demand and region. Hydroelectric plants, nuclear power plants, thermal power plants and renewable sources have their own pros and cons, and selection is based upon the local power requirement and the fluctuations in demand. All power grids have varying loads on them but the daily minimum is the base load, supplied by plants which run continuously. Nuclear, coal, oil and gas plants can supply base load. Thermal energy is economical in areas of high industrial density, as the high demand cannot be met by renewable sources. These plants can also withstand variation in load and consumption by adding more units or temporarily decreasing the production of some units.
The huge challenge for energy policy is to enable energy supply to be secure, low carbon and affordable. The need for energy, together with the economics of producing and supplying that energy to the end user, are central considerations in power plant investment decisions and operating strategies. Inevitably, there will be a point at which higher efficiency and lower emissions come at a cost which cannot be justified. Where economic and regulatory conditions exist which shift this balance consistently in favour of higher efficiency and lower emissions, improvements become a normal part of running a competitive business. The trend over time has been towards improved power plant performance.
The development of supercritical and ultra-supercritical steam cycles, with progressively higher steam temperatures and pressures, combined with modern plant design and automation, provide significant potential for further efficiency improvements and the mitigation of CO2 emissions.
The vast majority of natural gas in the United States is considered a fossil fuel because it is made from sources formed over millions of years by the action of heat and pressure on organic materials. Conventional natural gas is found in subsurface rock formations and is extracted through a well drilled into that formation. In recent years, an increasingly large proportion of domestic natural gas is produced from low-permeability formations, such as shale. Extracting natural gas from these tight formations uses hydraulic fracturing or "fracking" technology to increase permeability and enable the gas to be extracted.
The U.S. Environmental Protection Agency (EPA) is working with the natural gas industry to ensure that natural gas extraction does not come at the expense of public health and the environment (see EPA's Unconventional Oil and Natural Gas Development page).
Once extracted, the gas is separated from free liquids, such as crude oil, hydrocarbon condensate, water, and entrained solids. The separated gas is further processed to meet specified requirements. For example, natural gas for transmission companies must meet certain pipeline quality specifications with respect to water content, hydrocarbon dew point, heating value, and hydrogen sulfide content.
Oil is a hydrocarbon formed over thousands of years from the decomposition of dead plants and organisms. Intense heat and pressure on this material triggers a reaction, which leads to the creation of oil.1
Conventional oil is a term used to describe oil that can be produced (extracted from the ground) using traditional drilling methods. It is liquid at atmospheric temperature and pressure conditions, and therefore flows without additional stimulation. This is opposed to unconventional oil, which requires advanced production methods due to its geologic formations and/or is heavy and does not flow on its own.
Because of these variations, oil quality is a spectrum and the distinction between conventional and unconventional is not always black and white. Generally, however, if traditional drilling techniques are used in the oil production it is considered conventional regardless of its physical properties.
Conventional oil tends to be less expensive and complex to extract than unconventional oil due to the routine nature of the production techniques. This oil is also the most valuable in global markets because it requires the smallest amount of processing prior to refining to create value-added products. Consequently, many of our global conventional oil supplies have already been extracted, limiting the availability of these source for future extraction3.
Generally, drilling and well abandonment are well-understood and regulated processes but there are always risks with such industrial operations. In drilling, pressure must be regulated carefully to avoid accidents and immediate environmental impacts like land disturbance must be carefully monitored. After abandonment, well leaks can occur if improper procedures were taken.

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.
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.
Solar Energy is produced by sunlight. The photovoltaic cells are exposed to sunlight based on the form of electricity that needs to be produced. The energy is utilized for cooking and distillation of water.
Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source, although this is controversial. Renewable energy installations can be large or small and are suited for both urban and rural areas. Renewable energy is often deployed together with further electrification. This has several benefits: electricity can move heat and vehicles efficiently, and is clean at the point of consumption.[1][2] Variable renewable energy sources are those that have a fluctuating nature, such as wind power and solar power. In contrast, controllable renewable energy sources include dammed hydroelectricity, bioenergy, or geothermal power.
Renewable energy systems have rapidly become more efficient and cheaper over the past 30 years.[3] A large majority of worldwide newly installed electricity capacity is now renewable.[4] Renewable energy sources, such as solar and wind power, have seen significant cost reductions over the past decade, making them more competitive with traditional fossil fuels.[5] In most countries, photovoltaic solar or onshore wind are the cheapest new-build electricity.[6] From 2011 to 2021, renewable energy grew from 20% to 28% of global electricity supply. Power from sun and wind accounted for most of this increase, growing from a combined 2% to 10%. Use of fossil energy shrank from 68% to 62%.[7] In 2022, renewables accounted for 30% of global electricity generation, and are projected to reach over 42% by 2028.[8][9] Many countries already have renewables contributing more than 20% of their total energy supply, with some generating over half or even all their electricity from renewable sources.[10][11]
