Q: what type of renewable energy is Wind Power?
what type of renewable energy is Wind Power?

A: wind turbines are machines that rotate whenever the force of the wind blows by it. It transforms kinetic energy into mechanical energy. The latter is then converted into electricity. The power generated is dependent of the actual wind power. The stronger the wind, the more power is produced. The wind is a very good source of power as it is available all the time. It replenishes very quickly.

Q: Renewable energy – wind power How much does wind power cost?
I really have no idea how much windmills cost. I was just curious if there is a site somewhere that has costs to be windmills that are maybe like 500kW, 750kW or 1 megawatt producers of electricity? Does anyone know an approximate price or website with pricing for these?

A: I was working in west Texas last year for several months in the middle of thousands of them. I am an engineer so discussed this a lot with engineers building them.

Seems the average cost was about 2 million for 2 megawatts (Very high compared to conventional / nuclear)just for initial capital cost. They work great. Only take 6-8 MPH wind for them to start generating. The power from them is much higher cost primarily due to the high initial cost and the fact that the wind just doesn’t blow all the time so your investment may sit a lot of the time generating nothing. They also require enormous surface area and a large electrical grid compared to conventional.

I like wind power and Solar power, and think we should build more in deserted areas because even though the power is more expensive, it reduces emissions and reduces our dependence on foreign oil. It cannot provide the huge amount of cheap reliable 24/7 alternative energy we need (Only Nuclear can do that), but it will help.

Q: Describe all of the renewable energy alternatives: wind power, solar energy, and biomass fermentation?
o What are some challenges with using and managing wind power, solar energy, and biomass fermentation as alternative renewable
energy resources?
o Name at least one other renewable energy resource.
o Include a response to the following: Nonrenewable energy resources include coal,
oil, and natural gas. Describe three common challenges with managing
nonrenewable energy resources.

A: Okay, I don’t think anyone’s taken this seriously yet, so…

How about, hydro-electric, geothermal steam, wind turbines, augmentative passive solar, such as water heating and daylighting (somwhat different then solar lighting, or skylighting, although skylights count.) Also let’s not forget rain harvesting, and gray-water usage.these save water, and energy from a treatment, billing, delivery standpoint.

Now that I asnwered the name other part: challenges, what happens when there is no sun/wind/water-flowing, if you have all of these, it won’t happen that often, but when it does, are batteries a practical solution? Won’t they eventually wind up in land-fill off-gasing? If you only use one or two of the 3 majors, what about when any of those aren’t available? Availability is still a big concern, hopefully that will be the next stock-market bubble and drive a massive influx of green-products.

The common challenges with non-renewables, rather than starting from an environmental standpoint, how about we start with what they’re called. NON-RENEWABLE, eventually we will run out. It’s theorized that we’ve found all oil on earth, and will start a downward turn on production by somtime in 2008 or 2009. Aside from that, there’s the obvious global warming issues.

O hope this helps some.

Q: What is the best renewable resource, wind power, solar, hydrogen cells, nuclear, etc.?
What I mean by that question is, which method is the most efficient and the least polluting?

A: I agree with Pfo that hydrogen fuel would be the best technology. Until we develop it to full efficiency I would say the following technologies are the best:

1. Wind Energy
2. Solar Energy
3. Ocean Energy (tidal and wave energy)

Q: Is solar,nuclear or wind power renwable or non renewable resources. explain?
1. Is solar power a renewable or a non renewable resource?
2. Is nuclear power a renewable or a non renewable resource?
3. Is wind power a renewable or non renewable resource?
please explain, thanks i really need help!!!

A: Solar=renewable. Look outside, there’s TONS of sunlight every day. The earth utilizes only about 8% (I think. Maybe it’s less.) of the sun’s light shown on the earth. Most of it actually is reflected back towards the sun because of the ozone layer. Most of it falls on water or man made structures which aren’t photosynthetic or solar powered.
Nuclear power=Non renewable, but it provides so much energy from so little material, that’s hardly an issue. The issue is the meltdown factors. Nuclear power works by boiling water. There are two pipes, one with lots of pressurized water that passes by the reactors where nuclear fission is taking place. That pipe passes by another pipe of fresh cool water that often comes from a spring source. The first pipe boils the water in the second pipe which is the fresh water which turns into steam which turns turbines and creates energy. If there is a crack in the pressurized water which cools the reactors, the operators can’t just shut down the plant because if they turn off the reactors, they still keep producing LOTS of heat because they can’t stop fission instantaneously. If the water leaks out and there’s a full meltdown, the radioactive material will melt everything and continue going down and down into the earth killing everything in it’s path and making everything around the plant uninhabitable for a VERY long time until it finally stops reacting and cools down. Nuclear fission is a pretty stable process, but the safety regulations need to be figured out a bit more in detail. Another issue is what to do with the radioactive material after it is used up, that is why nuclear fission is nonrenewable.
Wind power is renewable. The turbines are turned by wind which is a renewable resource because wind is created by pressure being pushed on the atmosphere.

Q: What is the most used form of renewable energy: solar or wind power? (In Maine, USA)?
what is most used form of energy in Maine? Wind vs. Solar Energy? Which produces most megawatts, and which is owned more? No oppinions please, just please have proof. (websites, books ect)

A: Can’t find figures for Maine.

USA-wide, there is far more wind power than solar power:

http://www.maine.gov/oeis/docs/OEIS%20Comp%20Energy%20Plan.pdf

Over 34,000MW USA-wide, with 175MW in Maine:

http://www.windpoweringamerica.gov/wind_installed_capacity.asp

They think solar across the US could hit 28GW by 2016:

http://en.wikipedia.org/wiki/Solar_power_in_the_United_States#cite_note-0

And that’s with very fast growth and most of that will be in the sourth.

So I’m going to go with wind.

Q: What non-renewable resources do hydroelectric power and wind power help conserve?
I’m thinking that they help conserve coal.

What else?

A: Old Dinosaurs!

Q: Wind power Renewable Energy?
Waht is likelyhood of wind power as being an important source of energy in the next 3 to five years.

A: Like Bella just said. Wind power is already being used. One commercial example is, Sydney Water will use wind power to power it’s new desalination plant.

http://www.sydneywater.com.au/EnsuringTheFuture/Desalination/pdf/RenewableEnergy.pdf

Wind power technologies are also still developing and will have a greater role in the future.

However, this being said. Wind power alone does not have the potential to replace current energy requirements. An effective combination of multiple green energy sources is required to meet energy demands. Green energy does have the potential to meet all our energy needs.

Q: would you consider wind power renewable energy resources?

A: Yes,why not. The sun power also we get only during day time. Like wise we get the wind power intermittently. That can be stored and used or that can be substituted when it is available and you can go for fossil fuel power when you don’t get from wind. Wind,solar, sea waves, thermal difference in ocean water are all can be converted to use full as renewable energy.

Q: Why don’t we use only renewable energy like Solar and wind power?
Why can’t we just make the change? Train people in the coal industry to work in these new industry’s.

A: Wind turbines are only 15% efficient – so they are a waste of time/money.
They are only there as a “we are doing something” show for politicians – oh and did I mention our electricty bills are surcharged 15% to pay subsidies to the wind farm industry to run these loss making sumbols!!!!!!

The Lunatics (Labour Party) really are running the Asylum!

Q: Why does the UK government insist on calling Wind Power renewable energy?
The wind blows and moves on by.

Then later another wind blows usually from a different direction and moves on by.

The way the UK government talks it seems to think that there’s this great big lump of wind whizzing round the Earth all the time.

It didn’t seem to be like that when I was taught geography!

In fact thinking back to my days in Physics they taught me that energy could not be created or destroyed E=mc^2 and stuff like that!
So energy can not possibly be renewed if it can’t be destroyed.

Or maybe the Government has legislated so much that they have manged to change the basic Laws of Physics?

A: A comparative statement and a relative term in relation to fossil fuels.
It is of course nonesense as we use masses of fossile fuels to create the wind turbines/solar panels and wave booms in the first place. Plus the amount of energy used to convert and ‘transport’ the power generated and all the miles driven by the engineers to maintain the varu=ious units.
However it keeps a few off the streets and stops the masses from panicking as the think the government is ‘doing something’ and has their ‘little world’ protected and all is under control.

Still whilst we use up the resources to create a process to keep some semblance of normality we’re getting our ’share’.

Q: what are renewable energy alternative? wind power, solar, bio fermentation and?
I need one more renewable energy alternative

A: Nuclear, Hydrogen, Geothermal, Tidal flow, Wave action, Hydro(Dams),

Nuclear is probably the only option that with today’s technology that can supply the massive amount of reliable 24/7 power needed. All others are good, but are limited by location, nature’s variables, and space requirements.

Q: Which of the following would be a non-renewable resource?Petroleum, wind power, or geothermal power?

A: Petroleum because once used up it cannot be restored within the period of a generation plz 4 best answer

Q: Everyone talks renewable power. Is there even enough space to build enough wind and solar farms to supply?
all the energy needs of the planet. Will the environmentalists be happyif we cover the Sahara and Death valley in solar panels, or do they just sprout their crap and never consider the other side of the coin.

A: Sure, there is plenty of space.
Drive through Utah.
There is enough wind power in North and South Dakota, alone, to power the whole USA electric grid.
Coastal cities should be investing in tidal generators
Desert cities in solar power
The midwest is ripe with places to place dams for hydro electric power

It’s all just free energy, flying along. We just have to tap into it.

Q: what is the approimate cost of using wind power when compared to other renewable resources?

A: “Fuel” is free, it is just the cost of set-up of your wind machine and delivery of power to the customer.
