Question by SquidbillyReturns: Will this be part of Obama’s new energy plan? This sounds AMAZING, after reading it do you think this is a real possibility and how many jobs world wide could it create? Since the U.S. Government funded the initial research wouldn’t it strengthen the country economically and as well as make the

Image by On the Commons Question by : Energy…..we “are” energy!….:-)? I find it very tremendously interesting how everything in the universe, even us, and all matter is all pretty much made up of energy, condensed and compact, fully palpable and tangible energy, to me thats awesome, it truly does change your whole outlook on

Question by somber_pieces: Which renewable energy form has the least amount of negative impact on the envioronment? Solar is nice, but how much energy & chemicals are used to make the solar panels. Geothermal is nice too, except along with the steam comes the other nasty byproducts that come up with the steam, depending upon

Question by athorgarak: Do any of you know where I can go to receive funding for energy research on the following? I am currently developing several avenues of harnessing the energy of the oceans and tides. I currently know of at least 8 different developed methodes. Two of my methodes are, as far as I

Question by bob d: questions about atomic energy? I’m wondering about multiple things. atomic questions———————————- 1.When it comes to atomic energy,it seams like the media demonizes atomic energy,is that true? 2.Did the Chernobyl incident “happen” due to the disabled safety features? 3.Did the power plant had a containment “dome”,like all power-plants today? 4.Why does the

Question by Ottawa Mike: Is the climate change issue really about a push for renewable energy? Here is the scenario as I see it: We are being told to reduce CO2 emissions because they will contribute to catastrophic anthropogenic global warming. To achieve that, we are basically being told (forced?) to reduce coal and oil

1) looks ugly
2) takes up a lot of land
3) a lot of birds get killed by the windmill blades.
4) doesn’t generate continous energy (i.e. only when the wind is blowing).
5) doesn’t generate that much energy (per dollar invested) compared to other methods.

They cost resources (capital). They are unreliable and short lived and there are other power generation methods that do the job better.
They are noisy.
They are an eyesore.

Mainly cost and reliability. Cost could come down with further use and technological innovation. Can’t improve on the reliability, though, and that will always keep wind power as only a partial solution to the world’s needs.
Think of it, as we use more and more wind power, that means more and more the risk that we might need power when it’s not available (no wind that day). That greatly increases the instability of the power system. Estimates in Ontario, Canada, recently suggested switching to more wind power would have to be limited to something like 20% of total output. Some locals would be able to use higher ratios, but nobody would be able to use 100% except in very small areas backed up as part of very large, massively redundant (read overbuilt) distribution systems to bring in power from elsewhere when needed.
Wind power also is noisy and takes up large areas (some other disadvantages)

More expensive and more effort than other methods.
Cheers and good luck!

I think wind energy is the best solution for earth. Hopefully all engineers and developers will notice in short time. I don’t see any more disadvantages than other energy sources if you think globally (not your pocket)
