What are the advantage of alternate energy?
When you say alternate energy, I think of renewable energy and so here are the points of alternate energy.
Alternative energy is certainly the future ahead for us because whether you like it or not, we are running out of fossil fuel and probably can supply for a few more decades.
- They are renewable, you won't run out of them but some needs to be sustain like biomass. If we use too much the it will be non-renewable. Unlike fossil fuel, coal, oil, we won't run out of solar, wind, tide, geothermal, wave .etc
- You don't produce solid waste or contribute to global warming. Plus, you reduce the carbon emission, and contribute zero to greenhouse effect. You won't have to worry about the rubbish beside your house because they won't be much and you can even use those rubbish.
- Less war. Well, better national security. We already see the amount of conflicts and disaster we get with oil, and coal trading. So, alternate energy, you can get it locally. Benefits of it being local is you reduce transportation cost, and you make the government happy because they don't have to spend so much money on buying foreign energy.
- Cheaper. Maybe the first few decades won't be easy but after some time, our market will be stable and we won't have to worry about a sudden crisis of prices going up.
Alternative energy is certainly the future ahead for us because whether you like it or not, we are running out of fossil fuel and probably can supply for a few more decades.

Advantages of Nuclear Power . Â· Efficient : Nuclear plants can produce an awful lot of electricity, up to about 2GW, which is comparable to coal plants . Â· Reli…able : There is no need to worry about interruptions to the power supply: as long as there is uranium, there will be power. This is a stark contrast to most renewable energies which depend on the activity of the weather . Â· Clean : I'm using this term strictly to refer to the greenhouse gas emissions of a nuclear plant. There is some greenhouse gas emissions associated with the life cycle of uranium, as gases are emitted as it is mined and transported etc. However this is significantly less than the emissions associated with the burning of fossil fuels. Essentially, nuclear power would be "carbon-zero" if the uranium were mined and transported in a more efficient way. There are issues with radioactive waste, however. Â· Supply : No, it's not going to last forever, but at least what there is more easily accessible than oil. 24% of uranium resources are in Australia and 9% in Canada. These are hardly politically unstable regions!. Nuclear power plants don't take up much space. This allows them to be placed in already developed areas and the power does not have to be transferred over long distances. . Another advantage of nuclear power is that nuclear energy is by far the most concentrated form of energy, so it can be produced in large quantities over short periods of time. . The possibility for long term production is great since new reactors, where costly can be made when the old ones wear out. Oil reserves and other fossil type fuels are likely to run out at some point. Disadvantages of Nuclear Power . Â· Waste : High level radioactive waste is very dangerous. It lasts for tens of thousands of years before decaying to safe levels. If there is to be a "nuclear renaissance", a sophisticated method of storing the waste for this period of time must be designed. This point itself has sparked a surprising number of debates. Â· Proliferation : Some forms of nuclear reactor, known as "breeder" reactors produce plutonium, which can be used to make nuclear weapons. There are other reactors which do not have this problem, but it is another issue which must be addressed before the possibility of a nuclear future can be taken seriously. Â· Terrorism : While the chances of a modern reactor exploding like Chernobyl are near zero, it is quite possible for intervention to have quite horrific results. Nuclear plants would be very tempting targets to anyone wanting to disrupt the power supply and devastate an entire region in one foul swoop. Â· Cost : Nuclear plants are very expensive to run. I'm not an economist, but I believe nuclear plants are, like most other things, cheaper in bulk. Most of the cost comes from the initial building of the plant; the running costs are comparatively low.. Nuclear Power generates radiation, which can be harmful or even fatal to infected people. . A nuclear meltdown can often occur which will release massive amounts of radiation into the community. . Extremely radioactive nuclear waste is produced by nuclear power plants. This stuff can't be just thrown out. The US plans to move all its nuclear was to an underground dump by the year 2010. Currently it is stored in the plants. . Nuclear waste dumps can spontaneously combust without warning. . Nuclear reactors only last for about forty to fifty years, so where they are extremely productive, they break down and are costly to replace. . There are international dangers too. Some reactors produce plutonium which can be used to make nuclear weapons. If the whole world were to use these, they would have unlimited access to nuclear weapons it can produce alot of energy every year, more than a normal station can produce
What are the advantages and disadvantages of using atomic energy as an alternative to petroleum-based energy sources?
There are many advantages. Unlimited power. It is undisputedly cleaner. There is zero pollution after construction. They left hates it! All great reasons to build them. The… disadvantage is the disposal of waste. The creation of nuclear material is done by concentrating the material from tons of other non radio active material. This material is then used to generate heat, which turns turbines to make power. No radiation is created. None... zip... nada. We concentrate the material to make the issue more intense. The honest and logical solution would be to take the spent rods that no longer work for reactors and return them from where they came. If we mixed this material with tons of non reactive material in the same ratios and returned it to the same location, what is the net difference? Free power.
What are the advantages and disadvantages of using nuclear power as an alternative to renewable energy resources?
Renewable power, that is wind, solar,tidal,wave, biomass, geothermal, hydro, is never likely to be able to make up the 20 percent of electricity generated at present in the US… by nuclear. So if nuclear is not used, additional fossil fuel probably coal would have to be used. Which is preferable? There are other questions in the answered list on the general advantages and disadvantages of nuclear fission power
What are the advantages and disadvantages of using nuclear power as an alternative to petroleum based energy sources?
Just read any Asimov novel very fees able futuristic depictions with mini (fit into watch sizes) reactors fueling technology. However ultimately plutonium is a finite resource… so renewable energy options need to be considered seriously, apparently they are looking into separating the hydrogen in water through fission if this works this will provide an endless supply of energy although limited to the amount of water you can obtain, but the waste from using hydrogen is water so it goes back to be used again as infinitum, here's hoping...I won't bother with the pitfalls of using nuclear energy so openly all the radioactive waste because petrol clearly has its own side-effects although nothing so volatile.
One advantage is that it is safe for the environment.
\n. The ongoing discussion about energy is one that can be polarizing. So, just what is the advantage of alternative energy over fossil fuels? \n. While researching your opt…ions for your electricity needs, you will learn that an advantage of alternative energy is that once you purchased the equipment, you will no longer have a need to purchase electricity from a provider. This can be a life-changing event. With alternative energy, you can now supply your own home with all of the power necessary for your needs without the worry of power outages and other problems with providers. \n. In fact, you could even tap into their network of power lines and sell the excess electricity that your home will not need back to the power plant. They have to buy it from you. An advantage of alternative energy is that it is clean, meaning it does not produce the harmful pollutants that burning fossil fuels do. This makes the power plant want to buy this electricity from you to help them reduce the amount of pollutants that they release into the air. \n. After you have a good idea of how much your electric need will be, have the power company install a meter to measure how much electricity you generate for them. You will love to see the meter reader coming to see how much they are going to pay you, instead of it being the other way around inmost cases. The amount of money you will earn will be the difference between how much alternative energy you can produce, with the equipment that you have installed, and the amount that you consume. \n. Another advantage of alternative energy is that we are finding ways to use it in our vehicles. This will reduce the amount of oil that we will have to buy from other countries. Also it will cut down on the amount of pollutants released into the air. \n. The technologies that are being discovered for using alternative energy are changing the way we look at burning fossil fuels. The advantage of alternative energy over fossil fuels is that it can easily be replenished from the wind, the sun, or from water power. Fossil fuels are in limited supply and once we have used them all up, we wonât be able to get anymore. Once we have mined all of the coal that the Earth holds, we will not be able to quickly reproduce more. \n. With the population growing and the consumption rate of fossil fuels rising at an alarming rate, the need for alternative energy sources becomes more and more evident. Studies are currently underway for new ways to utilize this technology. .
\nOne advantage of alternative energy is that once the equipment is set up, it keeps producing energy for a long time with very little additional extra expense. It has several… disadvantages. Solar energy is only available during the day and can not be stored. It could be used to heat a lot more hot water than now and pay for itself in about a year. Using solar to produce electricity on house roofs is not really economically feasible at the moment. Wind is economical in certain locations. This country does not have the high voltage lines to ship the electricity from the northern high plains states. It is politically impossible to put large windmills off the coast of Massachusetts otherwise wind energy would provide a large amount of the electricity needed in the New England States.
What is the scientific and economic advantage of alternating current for the transmission of electrical energy?
the easiest way to generate large currents is to use the alternators which generates alternate current, generating direct current requires some sort of batteries or cells whic…h are not practical for generating high currents and also have a high cost.. Beside, transporting electrical energy through long transmission lines is subject to enormous losses due to the resistivity of electrical wires, so, we have to transmit the energy using high voltages to reduce these losses. high voltages are not directly usable in home appliances and other everyday devices, so we have to reduce this voltage to a suitable one. the best method to down convert high voltages is the transformers, and transformes only works using alternating currents.
Advantages: . Tidal energy is an alternative energy. . The energy produced is clean and non polluting. . There is no carbon dioxide or any other by-products released…. It produces no greenhouse gases or other waste. . It is a renewable energy that will help reduce our reliance on the burning of fossil fuels. . There are two tides every day and they can be relied on. The energy is there for the taking. . So the electricity supply is constant and efficient. . Once you've built it, the energy is free because it comes from the ocean's power . It needs no fuel. . It produces electricity reliably. . Not expensive to maintain. . Tides are definitely predictable. There are two tides every day and they can be relied on. So the electricity supply is constant. . Offshore turbines and vertical-axis turbines are not ruinously expensive to build and do not have a large environmental impact. . A plant is expected to be in production for 75 to 100 years . Uses an abundant, inexpensive fuel source (water) to generate power . May protect coastline against damage from high storm tides and provide a ready-made road bridge Disadvantages: . Holding back the tide allows silt to build up on the river bed. . The dams and barrages sometimes interfere with shipping. . You will need to find a way to connect the electricity to the grid. . Pose same threats as large dams, altering the flow of saltwater in and out of estuaries, which changes the hydrology and salinity and possibly negatively affects the marine mammals that use the estuaries as their habitat . Turbidity decreases as a result of smaller volume of water being exchanged between the basin and the sea. . The average salinity inside the basin decreases, also affecting the ecosystem . A barrage across an estuary is very expensive to build, and affects a very wide area - the environment is changed for many miles upstream and downstream. Many birds rely on the tide uncovering the mud flats so that they can feed. . There are few suitable sites for tidal barrages. . Only provides power for around 10 hours each day, when the tide is actually moving in or out. . It only provides about 7% of the power needed for England and Wales that means that some people get their energy close to free and some pay a lot of money . Water is not replenished, it cannot flow away so any dirt or pollution lingers around the coast much longer . Needs a very big piece of sea to be cost effective . Cannot be used inland . Barrage systems require salt resistant parts and lots of maintenance . Affects the lives of the people who rely on fishing for a means of living . Limited because the tide never speeds up or slows down, and occurs on 6 hour cycles. It is also dependent on the fetch distance. The fetch is the distance the tide rises and falls, so some beaches have a very small fetch, and others have a big fetch but hardly any have a large enough fetch to support tidal energy . Tidal energy is currently more expensive to generate than conventional energy or that from many other renewable sources. . Effects on marine life during construction phases. . Operation and control must be provided remotely and maintenance is complicated due to sea-basing of the generation facilities. . Sea-based moorings and towers to hold the generators must be placed on the sea bottom. . The generating facilities and mooring infrastructure are potential navigational hazards. . Is only available in a small number of regions - it requires a basin or gulf that has a mean tidal amplitude of 7 meters or more. Also need semi-diurnal tides where there are two high and low tides everyday. . Even with the best barrage designs, fish mortality rate per pass through the barrage is about 15%. Solutions to this problem have either failed or are too impractical and too expensive. . Dams used in the production of tidal power can raise tide levels. . Damages like reduced flushing, winter icing and erosion can change the vegetation of the area and disrupt the balance. . Expensive to construct . Power is often generated when there is little demand for electricity . Barrages may block outlets to open water. Although locks can be installed, this is often a slow and expensive process. . Barrages affect fish migration and other wildlife- many fish like salmon swim up to the barrages and are killed by the spinning turbines. Fish ladders may be used to allow passage for the fish, but these are never 100% effective. Barrages may also destroy the habitat of the wildlife living near it . Barrages may affect the tidal level - the change in tidal level may affect navigation, recreation, cause flooding of the shoreline and affect local marine life . Causes a continual loss of mechanical energy in the Earth-Moon system (Due to pumping of water through the natural restrictions around coastlines and viscous dissipation at the seabed and in turbulence. . May take additional energy from the system, increasing the rate of slowing. Estimates are 24 hours every 2000 years and a corresponding change in planetary orbit and climate.
I probably cannot list anything like all the advantages. First off, alternate energy is usually intended to stop polluting, or even reverse the trend to pollute. Alternate ene…rgy usually has small, absent or even negative global warming carbon footprints. The idea of a negative carbon footprint may not seem feasible, but the example of burning methane seeping from a landfill and using the energy for heat is easy to understand. Methane is about 35 times as bad as carbon dioxide as a global warming gas. Since it is seeping from the landfill anyway, burning it to CO2 helps reverse global warming. Alternate energy conserves resources. For example biodiesel uses grease or used vegetable oil instead of petroleum, conserving the petroleum. Alternative energy is often less expensive than energy from other sources. For example, one utility is currently selling electricity from burning methane for less than a nearby utility is selling energy from nuclear - and the nuclear price is going up faster than the price from methane. Alternative energy sometimes produces beneficial results that would otherwise be absent. For example cogeneration plants produce both electricity and heat. If the fuel is biomass, the customers get both products from a single fire, and the operation is carbon neutral because the carbon dioxide put into the atmosphere had just recently come out of the atmosphere. Alternative energy employs people in small organizations all over the country, it produces more jobs that traditional sources. Alternative energy uses local fuel source, keeping money in the local and national economies rather that spending on imports.
Alernative energy technology can reduce the eviormental impactof burning fossil fules.
Free fuel costs forever No pollution Local power generation reduces the need for foreign energy imports
In Solar Power
it is renewable and its good for the environment also it saves u money however for having solar panels fitted it could cost u loads
In Environmental Issues
Alternative energy resources such as solar power, wind power, etc, are an alternative to using fossil fuels, such as coal, oil and natural gas. The benefits of using alternati…ve energy are immense, the impact of using coal, oil and natural gas on global warming and the environment are devastating. Additionally, by using alternative energy resources we are saving the natural resources for future generations. (my hubby is a solar manager, and we are proud to be a part of this growing market that has helped create jobs during the tough economic times and keeps big companies like PG&E from making ALL of the money from consumers, basically having a monopoly on who we receive our energy from. Solar power can actually be converted and sold back to energy companies) :)
In Fossil Fuels
No carbon dioxide pollution emitted so no contribution to global warming.
In Renewable Energy
One advantage is that you will never run out.
Improved public health and environmental quality. Generatingelectricity from renewable energy rather than fossil fuels offers significantpublic health benefits. The air and …water pollution emitted by coaland natural gas plants is linked to breathing problems,neurological damage, heart attacks, and cancer.
