Renewable Energy

Parent Category: Energy
Renewable energy doesn't get used up, in the way that coal and oil do. It is still there the next day, such as sunshine; wind power; water power from rivers and oceans; and geothermal power, which uses the heat deep below the surface of the earth.
If you're talking about wind power, then yes.    Wind power is a renewable source of energy because wind is a  natural, re-usable source. Wind power is generated by wind  turbines. To put it simply, the wind turns the blades, which  spins a shaft, which connects to a generator, making...
One disadvantage for wind power is that it takes a lot of money to  build an actual wind turbine. You could also talk about the space  they take up which could be used for agriculture or housing.
Geothermal power can be used in our homes as air-conditioners andheaters. It is renewable as the Earth is constantly making heat.
There are some very deep sources of radiogenic heat with geothermal  power potential, like the Cooper Basin in Australia which lies 4.2  kilometres or over 2.5 miles underground. In other places in the  world heat is harvested very close to the surface like The Geysers,  a geothermal field in...
I don't want to avoid the question, but it is something like asking  how big a lake is. Some are tiny and some enormous. Similarly, you  may be asking about a small windmill on an farm in Lancaster, PA  producing kilowatts or a large "wind farm" that connects to the  east coast power grid and...
 Clouds   Particles in the atmosphere  Oceans  Snow and ice      Part of the solar energy that comes to Earth is reflected back out  to space in the same, short wavelengths in which it came to Earth.
It depends on many factors, such as weather conditions (how much  sun there is in the specific time, which can also be affected by  which hemisphere you're in). Speaking generally, solar panels have  low energy density (many are needed for a significant amount of  energy.) But after the initial...
1. It is very 'clean' - there aren't by-products.   2. It is renewable    and as a special...   3. It is free
 Advantages of Non-Renewable Energy   Because non-renewable energies seem abundant, like oil, gas and  coal, some experts believe if channeled correctly, our supplies  will be safe for future generations. Non-renewable energy sources  include oil and petroleum products, gasoline, diesel fuel...
Solar cells (also known as photovoltaic cells) are made of solar  cells. To be more specific, they are made of slices of a  semiconductor with a metal layer.
no one but birds . +++ . The question is "affect" without qualification - they may haveno physical effects but their aesthetic impact is considerable.
By production, 9.0%. By consumption, 6.2%.   According to the National Energy Renewable Laboratory 2013  Databook, renewable electricity grew to nearly 15% of total  installed capacity and 13% of total electricity generation in the  United Statesin 2013. See pages 8 and 9 for % coal, gas,...
Wind like waves and sunlight are created by natural functions of the earth as a planet. They do not require time to form a fuel like coal and gas. As these functions are "naturally occurring" they are considered to be renewable. They will, as far as we are currently concern always going to occur....
Pinwhel connected to a coil of wire that rotates within the  magnetic field of a (or 2) permanent magnets.
rubbing youre socks on the carpet, solar panels, lightening rods  thermal energy
Hydroelectric power plants generate electricity by the action of  the "falling" water spinning a turbine which rotates a wire inside  a big magnet.
Yes, the denser the cloud of water vapor, the more solar energy is  blocked, or more accurately "reflected" back into space.
OSHA, NFPA and EPA regulations specify what safety precautions must be taken at power plants. Also various state and local regulations must be considered as well.
by a generator that converts the wind power to electricity
Today in our day to day life we depend on Electricity to run all  over electronic product which makes our life more easier and  faster. But we soon forget that this generated electricity that we  are using is produced from non renewable substances like burning of  coal. which again causes...
What makes it a useful source? It's free, abundant and reliable. It  can be converted to a number of energy sources. 1) Photovoltaic  panels can convert sunlight to electricity. 2) you can use sunlight  to heat water for things like bathing and energy storage in  something like a water tank that...
There are a lot of manufacturers. The biggest in the world is  Vestas, based in Denmark.    Here are some wind turbine manufacturers in the US:    Clipper Windpower  General Electric  Nordic Windpower  Northern Power Systems  PacWind  Urban Green Energy  
It is used for heating, generating electricity, and as a fuel for cars and trucks.
Renewable energy sources are better for the environment and produce  electricity.
No, it can't be said that tidal energy pollute the world.
The energy is there, for anybody to harvest. Harvesting the energy  itself requires some advanced machinery, so it won't be entirely  free.
Most wind turbines are located in Australia as of 2010. There are many other places which use wind tubines but Texas is the main source. Wind turbines can be located anywhere there is enough room to place them and no danger to populace. The preferred locations are sufficiently windy and have...
Another type of concentrating solar collector that opticallyreflects and focuses the suns incident solar energy onto a smallreceiving area using mirrors or lenses is called a SolarDish Collector , or more technically, a point focusingcollector . By concentrating the sunlight to a single spot,...
a dutch builder can't lay foundations properly.
it decreases the amount of animal feed going out, being  distributed. which could be a could thing, you don't want wild  animals coming into large metropolitan cities
hav no idea mate, just look it up somewhere else cos i sure as hek dont no anything about dis stuff. Peace out dude
BC Hydro's (In Canada) various facilities generate between 43,000 and 54,000 gigawatt hours of electricity annually, depending on prevailing water levels. BC Hydro's capacity is about 11,000 megawatts.
Geothermal energy is harnessed from the natural heat of theEarth. ... To produce electricity, hot water or steam extractedfrom high temperature geothermal reservoirs in the Earth'scrust is piped to steam turbines at electric utilities that drivegenerators.
There has not been any given proof of this. So it shouldn't be taken seriously.
Double glazing helps the environment by saving on energy usage, keeping out noise and your mum :)
yes; aquamarine gems are a non renewable source.
Geothermal power is a renewable source of energy if it is utilised correctly.However if the geothermal resource isn't managed correctly it can be over-exploited and in which case there are doubts about whether this resource can be truly classed as renewable. Whilst the resource is eventually...
Windmills generate electricity on the spot. This electricity is  then cabled into the closest grid.
Location, Location, Location. If you're on a major river, Hydro is great (as long as it doesn'tinterfere with the environment too much). On the other hand, Solar is avail anywhere the sun shines. Edit: Hydro is preferable, it is much more efficient, however Solar ismore versatile, so yeah, it is...
I believe amazon and/or ebay would provide reverse motors of sorts,which generate electricity from movement upon the axil.
Liquid biofuels like ethanol and biodiesel can be used in cars and  trucks. Any sort of combustion engine can use biofuels, sometimes  with a little tuning.
The UK already obtains about 2% of its electricity from renewable sources, chiefly from large to medium scale hydro-electric plants.
Because solar energy can not constipate more than enough of its resource so if it has to supply energy to a large city the solar energy wouldn't be able to supply that much Hope this helped youTasnim Salem
it means when your subscription expires you have too renew it
A non-renewable resource is something that is not being replaced as we consume it. Oil is a good example of a non-renewable resource. It is used to make gasoline and other fuels, as well as plastics, such as grocery bags. We are using billions of gallons of oil every year, but it takes millions of...
Iceland is a geologically active area with hot magma presentbeneath the ground in many locations. For Iceland this is a clean,renewable, and easily accessible energy source.
renewable energy we can use over and over again. nonrenewable energy we can only use it once.
Because compared to the amount of Bauxite use we can not replace it in short period of time, we can make or find more Bauxite but not recover the amount we have lost, so it takes a long time too recover what we have used.

Any plant that produces fat can be used to produce biofuel. The  most common plants used are the oil seed plants such as corn, rape,  sunflour soybean, palm etc.
No, some energy is used for respiration, anabolic and catabolic metabolism.
The difference between a float charger and a trickle   charger is that the float has circuitry to prevent   overcharging. It senses when the battery voltage is at the   maximum level and temporarily shuts off the charge (floats   voltage at zero or a very minimal charge until it senses ...
many people in the world do. that's all i know.
The principal way that water is used in electricity production is  at hydroelectric power stations. Moving water falls though turbines  to spin them. The turning turbine shafts power generators which  produce power.   Hydroelectric power plants capture the energy of flowing water.  Water from...
It depends on what fuel is used.If the fuel is coal, natural gas, gasoline, or oil, then it is not renewable because no one makes these things.If the fuel is a biomass such as wood, it might be renewable or not, depending on whether it is regrown. Wood that is responsibly cut comes from trees or...

There is no tidal power plant in India as such but Gujarart has given a proposal for THE KALPASAR PROJECT which if started in if this year will finish till 2020.
PROVIDES ENERGY OR ELECTRICITY  hydroelectricity provides one fifth of the worlds energy
  Water.. lots of water from steam.
....but in countries like The Netherlands which are partly below  sea level, windmills are used to control the level of water.
Windmills use the power of wind and transforms that energy into kinetic energy (which causes the blades to spin), which in turn creates mechanical energy.Wind Energy
No, there is a govern that is connected to the pitch control of the blades. As the wind speed increases the blade pitch becomes courser. As the blades become more course there is less surface area presented to the wind so the blades slow down.
Light. White light is a mixture of various colors; some of them visible for our eyes, some of them not. (In the latter case, instead of "colors" the word "frequency" is usually used, since "color" implies that it is visible.)
A renewable resource is a resource that is able to be reused and  are usually man-made. Examples of reusable resources are shopping  bags, packaging materials, gift packaging, old towels and bedding.
What is one disadvantage of using windmills to generate electricity? Well, the answer is quite simple. Look outside your window. Is it sunny? You may only feel a breeze, which is not quite enough for the kinetic energy in the wind to be converted to kinetic energy in the windmill. The strength of...
Turbines actually make the electricity wind, water, and other  recources do the work of turning the generators to produce the  electricity.
Likely because being so far north, the angle of sunlight is notideal, plus the daylight hours are lower than other places, meaningthat you have less sunlight time to gather power.
Endless, scalable, and cheaper than ever. This year (2017) for thefirst time, the price of photovoltaic solar became cheaper thanthat of fossil fuels. There has never been a better time to gosolar.
Germany and areas surrounding it.
As the reciprocating pump operates though the reciprocation of the follower,it guides the suction and the compression of water in the pipe.That's so when the rotary motion of the rotor blade is converted into the reciprocating motion, which deliverit to the reciprocating pump, the suction and...
Well, it is very low maintenence. All you have to do is buy it, (which seems like a lot of money, but in long terms it isn't) then put it in your selected area and there ya go!
The waves usually get their energy from the wind. The wind pushes against any small irregularity in the water, creating small ripples, pushes against the small ripples producing larger waves, etc. The waves usually get their energy from the wind. The wind pushes against any small irregularity in...
It works by the wind blowing it around and inside, flour is made.
Um...LEDs? I think you mean the other way round - how do you convert solarenergy into DC Power? Or in other words, how do you convert energyfrom the sun into usable electricity? A basic system will include the solar panel itself, a chargecontroller, a battery, and of course, the load (lights,...
One reason why people disagree with wind power because Turbines can only cope with wind speeds of up to 30-35mph, otherwise they have to be shut down or else broken due to the speed of the wind
An example of a renewable resource is hydroelectricity and solar energy.
By pumping cold water into a fissure and making use of the heated water. Either by pre-warming it before heating further, thus saving energy, or if the water turns to steam, using that to drive turbines.
They are both electromagnetic rays and both are produced by stellar objects.
Well.. In the "old days" windmills would provide the energy to power machines for producing clothing, food & farming requirements. Back then, the windmills didn't rely on "the grid" which is the way we get electricity now. It wasn't connected then and the power simply came from the wind blowing...
