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 anatural, re-usable source. Wind power is generated by windturbines . To put it simply, the wind turns the blades, whichspins a shaft, which connects to a generator, making electricity.The...
One disadvantage for wind power is that it takes a lot of money tobuild an actual wind turbine. You could also talk about the spacethey 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.
The sun gives off a few billion wats per second. If solar power went mainstream, then the world would be set on energy for the next billion years until the sun explodes.
There are some very deep sources of radiogenic heat with geothermalpower potential, like the Cooper Basin in Australia which lies 4.2kilometres or over 2.5 miles underground. In other places in theworld heat is harvested very close to the surface like The Geysers,a geothermal field in California.
I don't want to avoid the question, but it is something like askinghow big a lake is. Some are tiny and some enormous. Similarly, youmay be asking about a small windmill on an farm in Lancaster, PAproducing kilowatts or a large "wind farm" that connects to theeast coast power grid and produces tens...
Clouds . Particles in the atmosphere . Oceans . Snow and ice Part of the solar energy that comes to Earth is reflected back outto space in the same, short wavelengths in which it came to Earth.
It depends on many factors, such as weather conditions (how muchsun there is in the specific time, which can also be affected bywhich hemisphere you're in). Speaking generally, solar panels havelow energy density (many are needed for a significant amount ofenergy.) But after the initial buy, it's...
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 andcoal, some experts believe if channeled correctly, our supplieswill be safe for future generations. Non-renewable energy sourcesinclude oil and petroleum products, gasoline, diesel fuel, andpropane,...
Solar cells (also known as photovoltaic cells) are made of solarcells. To be more specific, they are made of slices of asemiconductor 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 2013Databook, renewable electricity grew to nearly 15% of totalinstalled capacity and 13% of total electricity generation in theUnited Statesin 2013. See pages 8 and 9 for % coal, gas, petroleum,nuclear...
The energy given out by the sun is constant and free of cost makingit renewable. Say for instance you have a litre of petrol, at theend of its use it does not replace itself, its gone forever unlikethe suns energy.
There is a finite supply the world around us continues to circulate energy. Beneath us the earth is heated so it will always produce energy from the heat. Geothermal persay! Look that word up, it really helps.
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 themagnetic field of a (or 2) permanent magnets.
rubbing youre socks on the carpet, solar panels, lightening rodsthermal energy
Electrically heated seats, wing mirror defrosters and rear window defroster.
Hydroelectric power plants generate electricity by the action ofthe "falling" water spinning a turbine which rotates a wire insidea big magnet.
Yes, the denser the cloud of water vapor, the more solar energy isblocked, 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.
costs less than gas or oil. doesnt pollute the air and its naturall
by a generator that converts the wind power to electricity
Because it's renewable and non-polluting.It's also chep
South Africa has very few large rivers that flow through-out the year. Therefore, hydroelectric power stations is not the most suitable solution. South Africa has rich coal deposits and is also a prime candidate for solar electricity.
basicly any where in the world where yhe sun mostly shines like Fiji or India or even Samoa so there you go all what ur looking for They use solar power to charge the batteries for lights on buoys.
Today in our day to day life we depend on Electricity to run allover electronic product which makes our life more easier andfaster. But we soon forget that this generated electricity that weare using is produced from non renewable substances like burning ofcoal. which again causes pollution and...
What makes it a useful source? It's free, abundant and reliable. Itcan be converted to a number of energy sources. 1) Photovoltaicpanels can convert sunlight to electricity. 2) you can use sunlightto heat water for things like bathing and energy storage insomething like a water tank that keeps your...
There are a lot of manufacturers. The biggest in the world isVestas, 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
"Bad" is a bit harsh but the actual turbines make noise, and disturb the view. Some birds gets whacked by the blades as well.
It is used for heating, generating electricity, and as a fuel for cars and trucks.
Renewable energy sources are better for the environment and produceelectricity.
No, it can't be said that tidal energy pollute the world.
The energy is there, for anybody to harvest. Harvesting the energyitself requires some advanced machinery, so it won't be entirelyfree.
Not much, but the actual turbines make noise, and disturb the view. Some birds gets whacked by the blades as well.
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,...
Wind turbines don't use up any fuel, so they don't have any exhaust. Since they don't use any fuel, there's no fuel used preparing fuel for them either.
a dutch builder can't lay foundations properly.
Less than 0.05% of american's energy is geothermal
it decreases the amount of animal feed going out, beingdistributed. which could be a could thing, you don't want wildanimals 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
Often in the sea, but sometimes in lakes.
weathering is part of the environment.
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.
Solar power can be used to help power a house up to supply energy to the grid. Solar thermal power can be used in conjunction with conventional thermal power plants and save on fuel costs. Salt ponds can be used with solar thermal to extend operating hours at night. Spain and USA are big users of...
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 :)
Those are called "non-renewable" resources. They include the fossil fuels (coal, oil and natural gas) as well as any minerals and metals.
Yes, it is non-renewable.
I should think not. The center of the earth heats up because of the large mass of theearth which creates the gravity. The gravity of the earth packs theparticles very tightly together creating high pressures. Whenparticles are under high pressure they vibrate more violentlytogether which creates...
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...
The problems associated with non-renewable resources like coal, oil, natural gas, or uranium --which we rely on for electricity needs-- is the fact that these fuels is limited, and their use endangers our health and environment. Burning fossil fuel may cause chemicals that can induce cancer, brain...
Light travels through different things (such as air, water, glass, plastic) at different speeds. When a light wave is passing one substance and encounters another (for instance, traveling through air and gets to glass), the difference in the speed causes the light wave to bend. This is what causes...
2-36distances are possible because of the different densities and refractive qualities of warm and cool air. Thesudden change in density when a radio wave enters the warm air above a duct causes the wave to berefracted back toward Earth. When the wave strikes the Earth or a warm layer below the duct...
Windmills generate electricity on the spot. This electricity isthen cabled into the closest grid.
This is a matter of opinion, personally i think they should. I know many people complain about it 'ruining' the scenery but i think they are quite elegant. People also complain about the noise, but shove a nuclear powerplant there instead and they would be twice as annoyed.
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 andtrucks. Any sort of combustion engine can use biofuels, sometimeswith a little tuning.
The UK already obtains about 2% of its electricity from renewable sources, chiefly from large to medium scale hydro-electric plants.
every energy requires the suns energy the sun is the ultimate source of energy for everything -O-A2. Nuclear energy does not depend on the sun, nor does geothermal energy from the earth's core. Tidal energy is largely driven by the moon but the sun also has some effect.
There are around 10 Wind farms which are active (Jan 2010) for a total installed capacity of 1,130 MW Oklahoma stands in 11th place in the list of states in US with Wind Installations were Texas being at the 1st Place with 9410 MW.
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 you Tasnim Salem
The Power Generated by a Wind Turbine entirely depends on the capacity of the turbine which is installed.. there are turbines ranging from 1 watt to 10 MW that can be installed in a wind farm The installation of the turbine depends on the Wind Potential of the area.
The light at the equator hits the earth perpendicular to the surface to the earth. The further you are from the equator, the light comes in at an angle closer and closer to parallel. The closer to parallel the light comes in at, the more of it is reflected, so it receives less energy than the...
Wood is a renewable resource. Plant a tree, wait a few years and there you have another batch of wood.
"GEOTHERMAL SCIENTIST" The national average salary in 2007 was $74,010
it means when your subscription expires you have too renew it
No, assuming rain goes on falling the water required will always be renewed every year
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...
It depends. A hydroelectric power installation at a pre-existing dam (it's called retrofitting) generally has a relatively small effect on the surroundings, and very little effect on the river or stream that supplies it with water. However, a hydropower project that includes a new dam and reservoir...
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.
The solar cells do not work during cloudy,humid,cold or rainy weather. It can be used only during the summer seasons.
renewable energy we can use over and over again. nonrenewable energy we can only use it once.
The energy of moving air is captured by new versions of the medieval windmill, which was used to grind grain. Modern windmills have huge curved propeller-like blades that "pinwheel" and spin when hit by blowing wind. Each set of blades are set atop a tower and have an integrated turbine generator...
Wind turbines, used in combination with other kinds of renewable energy, can slow and eventually stop global warming if we also stop burning fossil fuels (coal, oil and natural gas).
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.
Bottom line....they do not want to look at them. Those people believe they chose to live in the country for its landscape and they see the wind turbines as ruining this for them. Because they do not want to see them, they fictionally create things such as 'Wind Turbine Syndrome', which has never......
The most powerful solar panel is the Sunpower Turnkey Solar Solution. If you are thinking of getting this, think again. This effiecient Solar Panel is only built for busieness and Government buildings.
Wind turns a propeller on a windmill, which in turn turns a turbine causing static electricity to build up and is "pumped" into a generator. From the generator it goes to a sub station that collects and distributes the electricity to buildings.
No, because tidal energy needs a large bay that fills up with water at high tide, but it also needs a narrow opening to the sea, so that the outgoing water rushes through at a great speed. Because there are only two tides a day there are not many places round the world where it is economical to...
