What is increasing most in China - coal energy or wind energy?
In 2012, for the first time, China increased its wind power production more than its coal power production!
- Coal power production rose by 0.3%, an addition of roughly 12 terawatt hours (TWh) more electricity.
- Wind power rose by about 26 TWh. This increases China's wind energy to 100TWh, putting it in third place after coal and hydro, and larger than nuclear in fourth place.

A large mass of air moving over the landscape represents aconsiderable amount of energy. By building devices that will spinwhen the wind blows, it is possible to harness some of that energy.Most modern wind turbines are several hundred feet high, withpropellers that have 3 blades, each one about 150… long.

coal is broken up peaces of plants . And wind is driven by the sun. so this creates energy for every one in the world to use .xx
Coal energy is energy derived from the burning of coal. Coal is essentially fossilized carbon.
it is formed by being burned which causes heat, which can also be converted into motion energy.
Most commonly through windmills. the wind pushes on a tilted blade causing it to rotate. A generator inside the windmill then truns the kinetic energy of the rotation into an electric current. u blow on it
In short, No. Coal comes in the middle of the pack when fuels are compared. Propane produces 21500 BTU per pound, Gasoline 17500 BTU per pound, Coal between 12,000 BTU per pound (Anthracite) to 10,000 BTU per pound (Bituminous) and wood (dried) 7000 BTU or so. On the other hand, Coal can be converte…d to Gasoline using a process developed during WWII, or to Methane (modern) or to "Town Gas", a mixture of Hydrogen and Carbon Monoxide. ( Full Answer )
None, however there are many dissimilarities. Coal is a fossil fuel. Burning it consumes a limited resource and generates CO2 which contributes to global warming. Wind generation, like solar power and hydro-electric generation do not involve consumption of minerals. Also, they are non-polluting form…s of energy. The only connection between the two that I can draw, are that, as coal prices increase, there are more investments in wind power. ( Full Answer )
Wind energy is associated with the movement of atmospheric air which is converted into kinetic energy. This energy has been used for sailing, irrigation, and more recently for power generation.
Coal is portable, so once it is dug up and processed we can send it almost anywhere. The others are rather geographically dependant. Solar energy is fairly well available to most populations, because we tend to live in fairly temperate areas (though the people who live close to the poles don't have …much of it available). Tidal energy is not easily available to those in the center of a large continent, but if you live on an ocean or sea coast it is hard to get away from. Similarly, wind energy is almost everywhere, though strong consistent wind that large energy companies like is fairly limited, but quite reasonable as a supplement to many individuals. ( Full Answer )
Wind energy is obtained by placing wind turbines in high-wind areas. The rotation of the turbine spins multiple large gears which power a generator, which in turn generates 100% green energy.
yes because enzymes are highly weighted proteins which produced from living cells and used in industrial and biological processes
Not really.. Energy is released when coal is burned. It is not coal itself, but the reaction of oxygen and coal once ignited that results in energy.
I'm not an expert, but I am an athlete inHigh school, so I'll give it a shot.. If you want to increase your energy the best thing to do is cover the basics;. 1. Make sure you are sleeping well. Getting a basic 8 hours of sleep is beneficial, and an extra hour or so should be sought after if you ar…e highly active/an athlete. If getting the full 8 hours a night turns out to be difficult, I find it helpful to perfect the ability of 10 minute napping. Throughout the day you are bound to have 10 minutes when you are waiting in a car, exhausted and taking a breather, waiting for a class to start, or merely procrastinating your next venture (me now XD).. Also, be sure you aren't sleeping too much. Sleeping for even up to 10 hours after a hectic busy day can be beneficial, but sleeping 10 hours a night, or not sleeping much for a few days and then going on a 16 hour luxury nap can hurt you more than not getting enough sleep can, especially when you start getting crappy shallow REM sleep (or whatever its called :P). Basically, put in an effort to get an average, consistent sleep pattern. As difficult as it sounds it is possible and you can get a lot more done on a good nights sleep in an hour then in an hour when you are dead tired. Think about going to bed early in order to get up early to finish a project. You can probably get it done faster that way.. 2. Eat properly. Eating too little of course will end in a lack of energy, and if you eat crappy foods (Corn dogs, pizza, candy, chocolate, cake, greasy burritos, that stuff you pull out of the freezer and don't know whats in it but it tastes good) than your body can't get the right nutrition from it and its as bad as not eating sometimes, and your body's reaction is to go into "starvation mode," not knowing when the next stash of real nutrition will come along, adding to fat deposits and making it nearly impossible to get rid of the ones present. Also, eating one large meal a day isn't gonna work either, as it will usually initiate "starvation mode" too. Just make sure to eat healthy foods - get a fair quantity of greens, and plenty of fruits and veggies. Keep amounts of consumed meats down to a reasonable level (Not every day) and eat grains as a staple - about 3 times a day in MODERATION. As in, don't eat 3 plates a meal. 1 - 2 (mainly for athletes) plates is good. Generally stick to 1 full plate though.. One reason that energy might be low is a Vitamin deficiency. Vitamin B is an example of a big one that helps the body get energy from food eaten. Taking a daily multivitamin can almost definitely help improve energy if one is not regularly taken already.. 3. Exercise. If you aren't an athlete, its OK. You can always jump in and do SOME form of exercise. There are plenty of running programs that are really good, and ordering a magazine like "Runners World" or something can always help out beginners with getting started and knowing how to train. If you think running has to be agony, then you are running too hard for beginning, and should look up some beginning running guides. Running isn't your thing? No problem, just find some form of exercise that will work for you - lifting weights, biking, swimming, plyometrics, even jump rope. Nothing is going to be really easy if you aren't used to exercising regularly, but effort never killed anyone that I know, and if people have died from it, obviously they were doing something right. :) So try working some, and you may be tired as you step up to a new daily challenge, but after about a week your body should pick up the memo and give plenty more energy. Again, I'm not an expert exactly, so proper nutrition and sleep changes should accompany increased muscular activity.. Finally, 4. Be Mentally fit. Having the right mindset is key, and that is one thing you can control freely. Just as you choose to be angry or sad or depressed (in my opinion, no offense) you choose how hard you are gonna make something. I am a strong believer in "Mind over Matter," and so far it hasn't proven me wrong. Just choose to be happy and willing to work hard. If you find yourself feeling down or reluctant or even complaining (Gosh Forbid!) then make a conscious decision to change that to a better mindset. Generally, this leads to changing of the mind over time, for the better if properly employed, and can be applied anywhere in life. A good ability to acquire. ( Full Answer )
Wind is an example of motion (kinetic energy). Using this kinetic energy it is possible to generate electricity. The kinetic energy of moving air initiates the force that turns a windmill's blades. It spins a drive shaft that in turn spins the shaft of a generator to make electricity. A gear box …located along the drive shaft increases speed and optimizes power generation. Longer rotor blades mean a larger "rotor swept area," the total area covered by spinning blades, increasing the energy that can be captured and generating more electricity. ( Full Answer )
Wind energy is kinetic energy, it is created by the force of air in motion.
Yes, kinetic energy can be converted into almost any other form of energy (if you can find the technology to do so) for example. into electric energy by using a spinning generator to produce electricity.
one reason is it will never run out sadly it does not always blow but they put wind turbines in windy spots (fields, plains, etc.) places where the wind will not be blocked by something.
Basically from the Sun. The Sun powers our weather systems, which is what makes the windsthat spins the turbines blow
Power generated from the wind. The power of the wind cause windmills to turn, and that turning is used to turn generators, and the generators give off electrical energy that we can use.
Most energy (almost half) is lost as heat via the cooling towers. Hope this helps :)
Renewable energy. Wind energy is made by the wind it is really very simple all it is is the wind blowing wind then that electricity is drawn into a large generator which is then formed into wind energy that can power your home appliences.
As water is heated in a coal-fired boiler, the enthalpy of the water increases. Note that enthalpy is defined as: . H = U + pV . where. H is the enthalpy of the system U is the internal energy of the system p is the pressure at the boundary of the system and its environment V is th…e volume of the system. . Also note that as a state function, enthalpy is expressed as a value relative to some reference state. For water, this is typically liquid water at the triple point, although other conventions are used such as liquid water at the normal freezing point. ( Full Answer )
It will probably not be "the" energy of the future, but it is quite useful because of its inifnite renewability, minimimal harm to the environment, and reliability for energy. However it lacks in how much power it can produce and how consistent it produces it, which is where its downfall is.
Yes coal was formed by the bio materials of forests and swamps and the energy as now came from the sun.
Communities all come together when a coal mine disaster occurs. Some coal barons donate magnanimously to their favorite charities, especially to congressmen unimpressed by the science of anthropogenic global climate change.
Wind energy relies on a propeller like instrument that is moved by the wind. When the blades of it are turning it is connected either directly, or through a set of gears to a generator of some kind. So that when the wind is blowing through the propeller causing it to spin it turns the generator whic…h produces electricity. ( Full Answer )
Yes In terms of energy yield and availability, it most certainly is. A large coal power plant can produce what a wind farm does in a much smaller space with fewer metal and labor resources used. Also, coal deposits in the earth are HUGE. They are so large in fact that they are expected to last over… a century even with our rate of power consumption.. No No, it is not. Coal: . produces huge amounts of carbon oxides (harmful to many living organisms and can seriously alter the atmosphere and environment, further damaging others); . produces sulfur oxides which have the same effects; . can only be obtained from certain places; . require rather large energy input to extract usable quantities; and . is very much a finite resource. On the other hand, wind turbines: . create no pollution at all, beyond that involved in construction (which per turbine, is very small indeed); . are a virtually infinite resource; . can be established almost anywhere; and . involve almost zero input after their construction (maintenance is all you need to do). ( Full Answer )
Because you're not exactly damaging the "Earth" (example: Global Warming, Green House Gases) you're using the natural air to make electricity. :)
SOUMYADIP PAL, ST.XAVIER'S HIGH SCHOOL, HALDIA , EAST MIDNAPORE,WEST BENGAL,(INDIA) (CLASS--8A/3) ;- Because of sun the natural disasters are occurring and before 10000000 years from now, many plants and trees got buried and thus due to the long natural occurrences such as, decomposing and compost…ing due to the action of bacteria and funguses resulting in the formation of coal. Another fact is that, due to the hot and direct rays of the sun, low and high pressures are created alternatively and in this way, wind is formed. hence, this is caused due to the presence of the original source of nature and that is :-sun ((for any extra suggestions, please email to:- firstname.lastname@example.org )). ( Full Answer )
The source of the energy in coal and wind can ultimately be traced to the Sun. Coal is the compressed remains of vegetation that grew millions of years ago, so that was produced by the sun. Wind is part of our weather, and that is also driven by the sun.
Wind energy is a natural rescource made by harnesting it's power threw a wind turbine. Coal is the dirtiest source of energy releasing sulfur and cabon monoxide into the atmosphere.
Wind energy is a sustainable source meaning it can be used repeatedly. It also doesn't produce CO2 so it is better for the environment.
The coal is burnt to heat water into steam. the steam jet in turn is used to push a turbine the spinning turbine is connected onto a generator that generates electricity. The energy from a nuclear materials is utilized in the same way.
The Sun. A fraction of the suns energy heats the air. Warm air rises higher into the atmosphere and cooler, more dense, air moves in to replace it causing the wind.
Well energy is a broad topic, in-terms of oil the US uses the most, roughly 25% of the worlds oil that is produced.
The energy source is the Sun. The heat from the Sun warms the air in some places more than others. Areas with warmer air have lower pressure, and because fluids (gases and liquids) always move toward lower pressure, large amounts of higher pressure, cooler air move toward areas with lower pressure, …warmer air. Also, the Earth's rotation causes the Coriolis Effect, which determines the directions of many of the world's prevailing (general) wind patterns. ( Full Answer )
Yes. but it is rather caused by the the force and the direction of the wind.
Coal is a nonrenewable resource, meaning once you use it, it's gone for good. Wind is a renewable resource and plus you can never run out of wind.
no, the sun creates the most but wind energy creates the second highest amount of energy.
Wind energy is kinetic energy, the energy of the moving air. The original source is the Sun. The sun powers our weatherpatterns, which is what make the air that spins the turbinesmove.
The United States produces more wind power than any other country, surpassing Germany, which previously produced the most
Hydroelectricity is the most common renewable energy in China. In 2009 it had an installed capacity of 197 gigawatts.
Natural Gas, Solar Energy, Wind Power. The best type of coal and the most energy efficient is the coal that's still buried in the ground... LEAVE IT THERE!! TJ Daniels poet
Per pound : coal. Its pure carbon, wood is a mixture of organic substances (including water).
AMERICA. In fact it has so many wind farms that it decreases the amount of pollution in the air by 1/3!
By burning the coal. The stored chemical eneregy is converted to heat energy. That may be used to create steam. Expanding steam pushes a piston or turbine, converting the heat energy to mechanical energy.
No. Coal generates more than half of the energy in the United States while wind power generates less than 1%. When talking about the amount of power (megawatts) produced, for example, the Nysted Wind Farm in Denmark has 72 turbines and a capacity of 165.6 megawatts. Assuming that 40 percent of th…at capacity can actually be realized, those turbines put out an average of about 66 megawatt hours in an hour. Producing enough power to account for all of what is now put out by coal-fired plants in the U.S. would require over 250,000 individual turbines. ( Full Answer )
Wind energy is a form of energy conversion in which turbinesconvert the kinetic energy of wind into mechanical or electricalenergy that can be used for power.
It is the kinetic energy in the wind, which is half the mass timesthe velocity-squared, summed up for every small element of air inthe wind.
