Essay on Conventional and Unconventional sources of Energy.
For example, wind, tides, solar, geothermal heat and biomass including farm and animal waste as well as human excreta are non-conventional sources of energy. Unlike the common sources which are derived from fossil fuels, non-conventional sources of energy are renewable or inexhaustible and do not cause environment pollution.
Energy is produced mainly from non-renewable sources such as petroleum, natural gas, coal and lignite. They are usually referred to as non-renewable, because extraction from the stock depletes the usable quantity remaining. And even if some is being formed, the rate of formation is too slow compared to the time scale of their utilization.
The conventional sources of energy are generally non-renewable sources of energy, which are being used since a long time. These sources of energy are being used extensively in such a way that their known reserves have been depleted to a great extent. At the same time it is becoming increasingly difficult to discover and exploit their new deposits.
All the commercial and non-commercial sources of energy are referred to as conventional sources of energy. Besides the conventional sources of energy (which are likely to be exhausted with the passage of time), there are some non- conventional sources of energy. They are: solar energy, wind energy and tidal power.
Conventional and Non-conventional Sources of Energy Energy is one of the major parts of the economic infrastructure, being the basic input needed to sustain economic growth. There exists a strong relationship between economic development and energy consumption.
With increasing demand for energy the non-conventional sources of energy, namely sun, wind, tide, biomass and energy from waste material; have gained importance in recent years. The non-conventional sources are abundant, renewable, pollution-free and eco-friendly. Therefore, this energy has a bright future. According to energy experts, the non-conventional energy potential of India is.
Here you can find Essay on Conventional and Non-Conventional Energy Sources in English language for 5, 6, 7, 8, 9, 10, 11, 12 and banking or other competitive exams students in 350 words. Energy is mainly produced from non-renewable sources like petroleum, natural gas, coal and lignite.
Essay on Energy: Importance and Sources. Article shared by: ADVERTISEMENTS: Energy is the key input in economic growth and there is a close link between the availability of energy and the growth of a nation. Since energy is essential to conduct the process of Production, the process of economic development requires the use of higher levels of energy consumption. There exists a strong.
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, tidal energy, biomass energy and geothermal energy etc. The energy obtained from non-conventional sources is known as non-conventional energy. These.
The conventional energy resources like gas, oil and coal are used everywhere starting from the household chores to industrial activities. As the conventional resources are subject to depletion nature and cannot be regenerated immediately, there is a rummage around for alternative sources of energy.
Although conventional energy such as coal, gas, and crude oil are the most popular energy sources, renewable energy including solar, wind, and hydroelectricity could provide the same amount of energy without the same detrimental consequences for our environment.
Non Conventional energy source SOLAR ENERGY. Two weeks of solar energy is roughly equivalent to the energy stored in all known reserves of coal.oil and natural gas on the earth. Solar energy may be directly used either by active solar system or passive solar system. Another potentially important aspect 0f direct solar energy involves solar cells or photovoltaic that convert sunlight directly.
The energy sources and their manner of use may be categorized as conventional and non-conventional of commercial and non-commercial, renewable and non-renewable, and terrestrial or solar, etc, but the environmental impact of these energy sources cannot be readily understood in isolation.
It has also been estimated that the existing sources of energy (coal, gas, oil, etc.) may exhaust in the near future and the world shall have to face the greatest energy crisis. The prices of oil have risen by three or four times the previous Ones During the last five or six years, the price of crude oil jumped from 2-50 dollars a barrel to nearly to 32 dollars a barrel.
Nuclear energy is one of the most environmentally friendly conventional sources of energy as it produces fewer greenhouse gas emissions during the production of electricity in comparison to sources like coal power plants. Although in case of accidents, this same nuclear energy releases in high amount in the environment. Also, the nuclear waste that remains is radioactive and hazardous.
NEL 9.2 Conventional Energy Sources 65 Fossil fuels are used to generate electricity. Th ey are also used for heating. Natural gas and oil are burned in furnaces to heat many homes, schools, and commercial buildings. Fossil fuels also provide the energy for virtually all of our transportation needs. Without gasoline, diesel, and jet fuels, our economy would come to a grinding halt (Figure 5.
