The conventional unloose energy sources are chop-chop depleting because of their excessive role inward the modern world. And that's why unloose energy or ability generation sectors are really much interested inward the utilization of renewable unloose energy sources. The conventional unloose energy origin includes Natural Gas, Coal, Nuclear Energy, Crude stone oil etc. The toll of these non-renewable fuels is nearly touching the heaven in addition to getting closer every day. But the toll of utilization of non-conventional unloose energy origin is non really inexpensive either. Cheap renewable unloose energy source promises a greater ability generation alongside a cleaner environment.
Please Read : Different Renewable Energy Sources
Expensive Conventional Energy Sources
Crude Oil
According to Brent Crude Oil the toll of 1 barrel stone oil was $116! Yeah that’s correct in addition to yet stone oil is expected to stay the predominant origin of unloose energy production! The demand of stone oil volition increment past times 1.7% inward the twelvemonth of 2025 because of the unloose energy consumption inward USA in addition to developing Asia. So it is high fourth dimension nosotros should expression frontward for a inexpensive reliable unloose energy source.
Natural Gas
Another really attractive non-renewable fuel is Natural Gas. According to the estimation the role of natural gas volition live on increased past times 67% past times the twelvemonth 2025. And thence the consumption of Natural Gas volition live on 151 trillion cft. If the consumption increases inward that charge per unit of measurement so it tin live on predicted that the life of Natural Gas volition live on really brusk on The Earth.
Coal
70% Steel production companies uses coal every bit fuel. 38% of the world’s electricity generation comes from coal. It has high calorific value but at the same fourth dimension really detrimental to the environment. The high lineament coal comes inward telephone substitution of a high price!
Nuclear Energy
Uranium is the principal fuel for producing unloose energy past times nuclear fission reaction. U235 is the primary fuel for nuclear ability generation. According to World Nuclear Association the toll of 1 kg Uranium stands USA $2360 (After conversion enrichment, fabrication)! And it is exclusively the operating cost!
Capital cost + Plant operating cost + External cost = $5300/kW!
Expensive Non-conventional or Renewable Energy Sources
Solar Energy
Sun is the origin of energy. The unloose energy from the Sun inward nineteen trillion toe (Ton of Oil Equivalent)/year. And the world’s unloose energy consumption is exclusively ix billion toe. So a fraction of sun’s unloose energy tin fulfill the unloose energy needs. Sun’s unloose energy is extracted mainly past times solar collectors. Photovoltaic Cells (PV) are used to shop the unloose energy from sun. Influenza A virus subtype H5N1 unmarried solar panel for household role tin cost upward to $35000 according to the ability output. And this cost does non trouble organization human relationship the taxes, battery in addition to installation cost! So clearly it is non the cheapest source.
Wind Energy
We larn air current because of the pressure level deviation on the dissimilar areas of the earth. The air moves from high pressure level to depression pressure level expanse in addition to it causes the wind. Wind unloose energy is truly derived from solar unloose energy because Lord's Day heats the footing in addition to creates temperature differences. Hot air expands in addition to rises upward in addition to cool air nigh the oceans rushes in addition to fill upward that space. That’s how air is circulated. Wind unloose energy potential is non available for role inward all the places. Energy density in addition to normality depends on geographical locations. Wind unloose energy is really erratic in addition to irregular. Wind turbine pattern is really complex in addition to needs a practiced investment. To do a large constitute based on air current turbines, majuscule intensive engineering is needed.
Geothermal Energy
The interior of the footing is total of molten materials. The inner heart has solid materials in addition to the outer heart is filled upward liquid stone named Magma (4000 aeroplane Celsius). Geothermal resources tin live on divided into this 2 parts –
- Liquid dominant resource, which involves
- Flash steam ability plant
- Binary Cycle Power Plant
- Vapor dominated resource.
Though geothermal unloose energy is a really practiced potential source, it has roughly limitations. Geothermal unloose energy is available inward the geothermal sites only.
Ocean Energy
It is variety of hydro unloose energy but it is mainly derived from Thermal radiations of the sun. The surface H2O of the body of body of water is heated but the deep body of body of water H2O yet remains cool. These temperature deviation tin live on used to larn OTEC (Ocean Thermal Energy Conversion). From the 19th century scientists are trying to brand this constitute run but it is non that pop because of the high cost of the plant. It needs really large diameter pipage which is needed to live on submerged a kilometer or to a greater extent than than that to larn the cool water.
Cheap Non-Conventional Energy Source
Hydropower origin – Tidal Energy
Hydro ability tin live on got from tides in addition to waves. Tidal ability constitute needs mechanical equipment. This unloose energy is mainly due to the delineate of moon.
It tin be
- Single basin unmarried tide
- Double basin unmarried tide
- Double basin alongside the ability trouble solid inward the separating dam.
It tin live on proved really useful for the countries having large H2O reservoirs. The fuel cost is absolutely nil. But the erection of this type of constitute tin conduct maintain years. And the charge per unit of measurement of render is really low. So the constitute owners or authorities tin suffer, running this type of ability plant. But it is 1 of the cheapest origin of renewable energy.
Biomass
According to my studies I intend Biomass is the most potential origin for unloose energy production. It tin live on got from woods areas, agricultural residues, Urban wastes, Industrial wastes in addition to natural vegetation.
Biomass – The Cheapest origin of Renewable Energy
Yes, I would country biomass because it tin role aquatic crops, vegetable stone oil crops, in addition to fauna wastes fifty-fifty human wastes for fuel production. Every 24-hour interval nearly 42 1000000 tons of solid waste materials in addition to 6000 1000000 cubic meters of liquid waste materials are generated inward urban areas. What yous volition do alongside all these huge waste materials materials? If these are utilized to attain ability than it would live on much meliorate for our environment. And these waste materials materials are non expensive for sure. Biomass tin furnish us alongside biofuels in addition to biogas.
Biofuels
Charcoal – These possess high unloose energy density in addition to tin live on burned at temperatures high every bit 600 degrees. Very practiced for household, commercial in addition to industrial uses.
Briquetting – It tin live on produced from kokosnoot shells, saw dust, wood chips etc. This are made into high density fuel element.
Vegetable oils – Palm, coconut, cotton, rapeseed in addition to soybean oils tin live on used every bit bio fuels. These tin mixed alongside diesel fuel to cast premium score fuel.
Biogas –
Biogas tin live on produced from digestion of the waste materials materials similar human waste, fauna waste materials in addition to constitute waste. Biogas is mixture of Methane, Carbon dioxide, Hydrogen, Hydrogen Sulfide in addition to Nitrogen. Here Methane CH4 is predominant (55 -65%). Methane is really build clean burner.
Biogas Plants are every bit good really inexpensive to fabricate. There are 2 really pop designs to attain biogas
- Floating Drum Biogas Plant (KVIC model) or Chinese Biogas Plant
- Fixed Dome Type Biogas Plant (Indian Biogas constitute design, Janata Model)
Biodiesel
Biodiesel tin live on produced past times mixing organic stone oil alongside diesel. Non-edible stone oil seeds are much preferred for the production of the oil. These produces really modest amount of CO2 and null sulfur. These fuels conduct maintain really high flash points so they are easily transported without whatever danger of self-ignition in addition to combustion. This fuels plough over high octane ratings. Biodiesel tin live on produced from Jatropha Curcus, Jojoba, Sunflower, in addition to Soybean in addition to every bit good from peanut. Amongst them Jatropha is the cheapest. It is economically favorable in addition to it costs $0.08/kg of seeds! Where Jojoba seeds costs $3.39/kg.
So Biomass derivatives – biofuels, biogas in addition to biodiesels are the cheapest origin of renewable energy.
