How much does it cost to build and maintain a power plant for generating electricity with solar energy?
this is a question with several differant answers...... depending on consuption if its going on a consuming structure co-generating. or a stand alone generation station. the most cost effective would be a hybrid. thermal/photovoltaic. the thermal would heat a closed contained liquid and make ste…am to turn large turbine.. $150,000US will get u quite the little generator. $1,000,000US u have a major player. my general rule is $15us per sq ft of heating/cooling space.. I am presently puting together the single largest solar project of its kind. entire subdivisions of low cost modular homes with the entire roof as the mini-generating station. so if u put up say 400 units. when this hole subdivision comes on line u have a major Generating Station.. maitaining a plant with no moving parts to wear-out, well except to send some one to clean the panels off once every 6 months wound not be much up-keep....... the panels have 20 to 25yr warrenties and 30yr life. some put up in the late 60's r still generating..

Solar energy is powered by light emitted by the sun. The sun gets it's energy from nuclear fusion at it' score.
Answer It isn't. Just because it harnesses energy from the sun, i.e., a natural source, does not make it efficient. To understand efficiency, one must understand the relationship between economics and efficiency. That which is economically efficient is efficient. Thus the issue is not where the e…nergy comes from, but how much energy is produced through solar technology, and how much energy is consumed (i.e., what is spent) in harnessing energy from the sun. In order to harness energy from the sun, solar panels must be built. This requires labor and time, as well as mining for natural resources such as copper, etc. Throughout all of these activities, energy is consumed. In fact, EVERYBODY CONSUMES SOME FORM OF ENERGY IN EVERYTHING THEY DO. In order for A to spend energy doing X, B must spend energy producing, for example, food in order for A to sustain himself. One needs inverters and charge controllers in order for solar systems to work. Batteries must be produced, used, and replaced as well, which is a huge drain on resources, i.e., energy. Thus the energy produced vs. energy consumed in solar power makes it inefficient . One of the most efficient, and thus inexpensive, forms of energy comes from coal. Barack Obama has already stated his desire to destroy what remains of the coal industry in the United States. When that happens, common people will find turning light bulbs on to be a form of luxury. Comment Unfortunately, too many discussions on this topic confuse several very different forms of energy efficiency to reach an incorrect conclusion: * conversion efficiency: Given some "raw" natural resource containing some theoretical amount of energy R Joules (light from the sun, coal deep in the earth, etc.), when I convert that resource into E Joules of electricity, what is the efficiency E/R ? This efficiency is always less than 100% for every energy source. This number is easy to measure, but irrelevant on its own. * extraction efficiency: Given some "raw" natural resources, I have to put in a certain amount of energy S Joules (roughly equivalent to start-up costs: the energy to run the tools to dig into the earth and pull coal out of the earth and carry the coal to the coal-powered electric generator; the "embodied" energy required to build solar panels; etc.), after which I get E Joules of electricity out. This ratio E/S had better be more than 100%, otherwise you're better off doing "nothing" and converting those S Joules into electricity directly. Typically an oil well flows freely when it is first drilled (it takes very little energy S to run the pump in order to get lots of energy E out), but it gets more and more difficult to pull the next barrel of oil out of the ground. In theory, you might reach the point where it would take more gallons of oil to run the pump all day than it produces that day -- a smart operator will shut down that well before that happens. Some of the very first solar cells produced had a E/S ratio less than 1, but today's solar cells (over their lifetime) produce 6 to 10 times the amount of energy required to produce that solar cell. See the "Net Energy Analysis" link below. * Economic efficiency: some ways of producing electricity require constant attention by lots of high-paid people; other ways are more-or-less automatic once set up. Some ways of producing electricity require mind-boggling amounts of start-up costs; others can get started on much less. Some locations have a government that requires certain ways of electricity production to pay high insurance and security costs, other ways have lower costs, and some ways may be subsidized. Sometimes there is a method of producing electricity that is perfectly reasonable, when considered by itself, and there are more than enough people who would be willing to fund and build it, when considered by itself; but it doesn't get built because those people found some other way of producing electricity that generates more electricity at lower cost. * Sustainable efficiency: There is a finite (although very, very large) amount of matter and energy available to us. There are some ways we can "use" matter and energy in ways that our children, grandchildren, etc. can continue to do the same for thousands of years. There are other ways we can "use" matter and energy in ways that "use it up", forcing our children, grandchildren, etc. to find some other way to get the energy they need to survive. However, after the solar panels are put in place, they do less damage to the Earth. They are dependent on a renewable source : the Sun. Coal, fossil fuels, eco fuels etc. all come from Earth, and coal and fuels cannot be replenished. The Sun is a constant, renewable source. Solar energy would be efficient in reducing carbon emissions and stopping greenhouse gases, as solar energy is directly changed to electrical energy. Coal and fuels must undergo chemical processes, and form carbon dioxide and other gas emissions which are harmful to the atmosphere, increasing greenhouse gases. (MORE)

Anything. All things that can be powered by fossil fuels (electricity) can be powered by solar power :)
There are two types of solar energy plants: 1. Plants that use sun's rays directly to heat a medium (sometimes a hybrid plant with natural gas).

It's renewable energy. That means, if we use as much sun as we can today to produce electricity, it still all comes back tomorrow just as strong. Not like coal or oil which can only be used once. When we've burnt the coal or oil, it's gone.
The term is used to describe either but there is a difference in solar Electricity and solar energy. Solar Energy is a very broad term which can describe Solar electric (PV), Solar Thermal, Solar Heating etc., just about any form of power that can derived from the sun. Solar Power or Solar Ele…ctric is generally related to solar photovoltaics, specifically which is taking photons from the sunlight and turning it directly into electrical current. Answer The correct term is solar energy panel , despite the term 'solar power panel' being widely used. This is because solar photovoltaic panels supply energy. The rate at which they supply energy is a measure of their power. (MORE)
A very small percentage so far, 0.05%. However, scientists and the public are looking to have more of the world's energy come from solar power plants. . "Solar power...would represent the annual output from 150 coal-fired power plants" by 2025, the European Photovoltaic Industry Association (EPIA…) and Greenpeace said. The report said photovoltaic systems, which turn sunlight into power, now generate 0.05 percent of world electricity and could rise to 2.5 percent in 2025, the main horizon for the report, and then leap to 16 percent in 2040.. Not many people know this, but solar, wind, and electricity only account for less than 1% of the worlds energy combined. (MORE)

Plants use solar energy through the process of photosynthesis. In this process they absorb sunlight, water from the ground, and carbon dioxide from the air to create oxygen as a waste product and glucose as their source of food. Plants use the sun's energy to perform electrolysis and break down wa…ter into hydrogen and oxygen. They then combine the hydrogen with carbon dioxide to make C6H12O6, or glucose. The equation is CO2 + H2O -> sun and chlorophyll -> C6H12O6 (MORE)
A power plant produces electricity (electromagnetic energy) which is delivered to a user's home. There is no transformation as electric power is created at the plant, delivered via the power grid and used in the home.

In a silicon solar cell, light energy (a photon of energy >~ 1.1eV) is absorbed in silicon and the energy absorbed excites an electron-hole pair so charge particles are formed. If there is an electric field, the charge particles will separate and an electric current occurs.
One way to capture the sun's energy involves using giant mirrors.In a solar power plant, rows of mirrors focus the sun's rays toheat a tank of molten salt.

Solar energy can be used for a number of things. It is an alternative to harmful fuels. It helps the planet in many ways. For example, buildings, cars, machines, and other works use solar energy to provide for their needs. ^_^
The function of the main transformer at a power plant is to step up the generator voltage to the transmission system voltage.

\nThe energy transmitted from the Sun. The upper atmosphere of Earth receives about 1.5 Ã 1021 watt-hours (thermal) of solar radiation annually. This vast amount of energy is more than 23,000 times that used by the human population of this planet, but it is only about one two-billionth of the Sun…'s massive outpouringâabout 3.9 Ã 1020 MW. See also Sun.\n\nThe power density of solar radiation measured just outside Earth's atmosphere and over the entire solar spectrum is called the solar constant. According to the World Meteorological Organization, the most reliable (1981) value for the solar constant is 1370 Â± 6 W/m2. See also Solar constant.\n\nSolar radiation is attenuated before reaching Earth's surface by an atmosphere that removes or alters part of the incident energy by reflection, scattering, and absorption. In particular, nearly all ultraviolet radiation and certain wavelengths in the infrared region are removed. However, the solar radiation striking Earth's surface each year is still more than 10,000 times the world's energy use. Radiation scattered by striking gas molecules, water vapor, or dust particles is known as diffuse radiation. Clouds are a particularly important scattering and reflecting agent, capable of reducing direct radiation by as much as 80 to 90%. The radiation arriving at the ground directly from the Sun is called direct or beam radiation. Global radiation is all solar radiation incident on the surface, including direct and diffuse. See also Solar radiation.\n\nSolar research and technology development aim at finding the most efficient ways of capturing low-density solar energy and developing systems to convert captured energy to useful purposes. Also of significant potential as power sources are the indirect forms of solar energy: wind, biomass, hydropower, and the tropical ocean surfaces. With the exception of hydropower, these energy resources remain largely untapped. See also Energy sources.\n\nFive major technologies using solar energy are being developed. (1) The heat content of solar radiation is used to provide moderate-temperature heat for space comfort conditioning of buildings, moderate- and high-temperature heat for industrial processes, and high-temperature heat for generating electricity. (2) Photovoltaics convert solar energy directly into electricity. (3) Biomass technologies exploit the chemical energy produced through photosynthesis (a reaction energized by solar radiation) to produce energy-rich fuels and chemicals and to provide direct heat for many uses. (4) Wind energy systems generate mechanical energy, primarily for conversion to electric power. (5) Finally, a number of ocean energy applications are being pursued; the most advanced is ocean thermal energy conversion, which uses temperature differences between warm ocean surface water and cooler deep water to produce electricity. See also Biomass; Photovoltaic cell; Wind.\n\nSolar energy can be converted to useful work or heat by using a collector to absorb solar radiation, allowing much of the Sun's radiant energy to be converted to heat. This heat can be used directly in residential, industrial, and agricultural operations; converted to mechanical or electrical power; or applied in chemical reactions for production of fuels and chemicals.\n\nA solar energy system is normally designed to be able to deliver useful heat for 6 to 10 h a day, depending on the season and weather. Storage capacity in the solar thermal system is one way to increase a plant's operating capacity.\n\nThere are four primary ways to store solar thermal energy: (1) sensible-heat-storage systems, which store thermal energy in materials with good heat-retention qualities; (2) latent-heat-storage systems, which store solar thermal energy in the latent heat of fusion or vaporization of certain materials undergoing a change of phase; (3) chemical energy storage, which uses reversible reactions (for example, the dissociation-association reaction of sulfuric acid and water); and (4) electrical or mechanical storage, particularly through the use of storage batteries (electrical) or compressed air (mechanical). See also Energy storage.\n\nPhotovoltaic systems convert light energy directly to electrical energy. Using one of the most versatile solar technologies, photovoltaic systems can, because of their modularity, be designed for power needs ranging from milliwatts to megawatts. They can be used to provide power for applications as small as a wristwatch to as large as an entire community. They can be used in centralized systems, such as a generator in a power plant, or in dispersed applications, such as in remote areas not readily accessible to utility grid lines.\n\nBiomass energy is solar energy stored in plant and animal matter. Through photosynthesis in plants, energy from the Sun transforms simple elements from air, water, and soil into complex carbohydrates. These carbohydrates can be used directly as fuel (for example, burning wood) or processed into liquids and gases (for example, ethanol or methane). Biomass is a renewable energy resource because it can be harvested periodically and converted to fuel. See also Carbohydrate; Photosynthesis.\n\nWind is a source of energy derived primarily from unequal heating of Earth's surface by the Sun. Energy from the wind has been used for centuries to propel ships, to grind grain, and to lift water. Wind turbines extract energy from the wind to perform mechanical work or to generate electricity.\n\nOcean thermal energy conversion uses the temperature difference between surface water heated by the Sun and deep cold water pumped from depths of 2000 to 3000 ft (600 to 900 m). This temperature difference makes it possible to produce electricity from the heat engine concept. Since the ocean acts as an enormous solar energy storage facility with little fluctuation of temperature over time, ocean thermal energy conversion, unlike most other renewable energy technologies, can provide electricity 24 h a day.\n (MORE)

No, solar energy is produced by the sun. We can capture it with solar panels, or solar farms, which are banks of panels or other gadgets to capture the sun's heat and energy. We can then transform this into electricity.
Energy in a system may be transformed so that it resides in a different state. As a source of energy, nothing matches the sun. After passing through the Earth's atmosphere, most of the sun's energy is in the form of visible and ultraviolet light. Plants use solar energy to create chemical energy thr…ough photosynthesis. Humans regularly use this energy burning wood or fossil fuels, or when simply eating the plants. (MORE)
I'm not sure what you mean by this question. Do you mean "How is solar engergy transformed?" or "What are some examples of solar energy transformations?"
It just is Solar energy originates from nuclear fusion in the sun, so the question seems to be illogical. In fact solar energy is transformed into chemical energy in all living vegetation, by photosynthesis
can someone answer this! The kinetic energy of the wind is captured and transformed into mechanical energy which then drives a generator and it becomes electrical energy.

Because the fuels we burn now like coal and natural gasses will eventually run out. Not only that but burning things like coal is destroying our ozone layer and killing nature. Finding ways such as solar power and wind power will basically save our planet.
Solar energy plants are generally located where there are few clouds. The desert is a good location.
The kinetic energy of water is transformed into mechanical energy of the turbine which is transformed into elecrtical energy.
It is very inefficient. The best and most expensive systems are only about 10% efficient.
Is it true that power plant that uses fossil fuels transforms chemical energy to thermal energy to mechanical energy to electrical energy?
Yes it is true that a power plant that uses fossil fuels transforms chemical energy to thermal energy to mechanical energy to electrical energy

The energy in coal is stored as chemical potential energy.. When the coal is burned, this chemical energy is converted to heat. The boiler converts this thermal energy into pressure of the steam.. The pressure energy in the steam is then converted into rotating mechanical energy using the turbine…. As the turbine spins the generator, the generator converts this into electrical energy.. (MORE)
No transformation is necessary. The energy arrives here ... just as it left the sun and traveled through space ... in the forms of heat, light, radio waves, ultraviolet radiation, microwaves, X-rays, and gamma rays. The dangerous ones are largely absorbed by the atmosphere.
Solar power systems do not generate any exhaust or air pollution, and once the solar power system is installed, the energy from the Sun is free. On the other hand, solar power only works during the daytime, and not even then in bad weather. In the winter, when you really NEED the heat, the Sun is …at its lowest elevation and you'll generate less power. Solar power is OK for fixed installations, like your home or office, but doesn't work for mobile installations like cars. Large solar power plants take a lot of room, and are generally located quite a way from the city. The fixed solar plants (and large wind turbine farms) are fatal to a lot of birds. Fossil fuels are rich in energy, and are relatively plentiful. (In fact, new fossil fuel reserves are being discovered faster than we're using them up.) Using fossil fuels generates some exhaust and pollution (although, modern engines are much cleaner and efficient than they were even 10 years ago). (MORE)
