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 U.S. the world's leading energy provider one way or another? What do you all think?

Here's a quote
The scientists behind the technology, which has been developed in research funded by the US government, say that generating power in this way would potentially cost only around 3.5p per kilowatt hour, compared to about 4.5p for wind energy and between 10p and 31p for solar power. They say the technology would require up to 50 times less ocean acreage than wave power generation.

Also at 3.5 per KWH it's cheaper according this this table than any other major energy source

He mentioned ethanol, the production of which has been proven to be disastrous to the environment as well as damaging to food supplies.

He harped on electric cars which, again, create more pollution through the increased demand on power generation.

Wind & solar are useless outside of Jr High science projects.

So what mythological clean energy does he intend to throw away our money on?
How silly of me. Evidently everyone can have free power from wind or sun, we all just choose to pay ridiculous rates to burn fossil fuels.

Ethanol is a RENEWABLE fuel, but it is not a CLEAN energy source. This has been known for years. Do you people read anything other than fringe websites and propaganda?

As for Iowa... Not a single commercial wind farm operates without subsidies to stay afloat. They are economically unviable. In other words, the entire country is paying so Iowa can pretend wind energy is practical. It would be impossible to duplicate this nation wide.

I've seen and heard the ads againt the proposition 87 that states that it may cause gas prices to rise and may cause a reduction in oil supplies. What I want to know is exactly what other alternatives are there that will make it easier to produce a non oil energy source?

Do you know of another "clean" energy source that will be ready before then.

also,
How does the cost of methane compare to the current cost of fossil fuels as an energy source?
how much money will be saved by using methane technology in the long term?
Does methane technology create any extra employment opportunities?

Thanks!

i have herd dat wind speeds at some islands close to antartica have been known to average 200-300 km/hr why cant we tap dis huge energy source by building windmills dere...we could use superconductors to transfer energy to de mainland with out much loss..
i would do it if me a billionaire

If you can't make all of your solar panels in your country, how is that energy independence? If you have to pay China for solar panels, then the sunlight is not yours.

What is the true cost of of solar and wind power per kilowatt hour, not counting subsidies? What energy source will be used when there are cloudy days and no wind, and at night?

Will you in the future be crying about BP and Exxon as "big lithium"?

It is free. We can put a windmill everywhere. And it is better than solar because you can use it night. Name another energy source that is free and does not pollute. The government should give free windmills to everyone.

- where in Canada/Ontario is this method used?
- advantages and disadvantages of using this method
- benefits or hazards to the environment when using this method
- how does energy production using this energy source compare with energy production from solar power?
- how much energy can be produced by this method; is it enough to be used alone or must it be used with another energy source?
- summarize the process
- are there any commercial products that you know of that are powered by wind energy?

If you could help answers any of these questions, or just give me good pictures or websites to find information on it would be super helpful. Thanks!

For my IPC class, I'm supposed to gather information on people's stories/recounts/opinions about wind as an energy source and what they did or didn't like about it, so I was hoping some of you could help me out. Thanks for any and all help given.

I have to create a Bill that could get passed by congress in my Goverment class.
Since Democrats are all about the enviroment I was thinking making it mandatory for Business and schools to use solar energy. Which is an Altertive Energy source. I would like another opinion on it. I would really appreciate it. Remember its only for a mock cogress in my Gov class.

1. Study after study shows that wherever wind development was put in place, natural gas demand went up and the environmental benefits were the opposite of what the advocates expected.

“Cycling” coal plants to accommodate wind generation makes the plants operate inefficiently, which drives up emissions. Moreover, when they are not operated consistently at their designed temperatures, the variability causes problems with the way they interact with their associated emission control technologies, frequently causing erratic emission behavior that can last for several hours before control is regained. Ironically, using wind to a degree that forces utilities to temporarily reduce their coal generation results in greater SO2, NOX and CO2 than would have occurred if less wind energy was generated and coal generation was not impacted.”

2. There is a huge disparity between installed capacity and actual output into the system. In many cases the actual output in the system is less than 20% and in some cases even far less.

There are other unsavory facts that are included in these graphics such as the area required by a wind farm compared to, e.g., nuclear power plant. The Roscoe wind farm in Texas occupies 100,000 acres for a bit less than 800 MW of installed capacity; the Palo Verde nuclear power plant in Arizona occupies 4,050 acres (4 percent of the Texas wind farm) but has a 500 percent larger power capacity (almost 4,000 MW.)

Even more obscene are the government subsidies that go into wind power. For an energy source that barely exceeds one percent of energy output, wind subsidies are per megawatt hour, about 60 times of the {content}.44 per megawatt hour that go to the mainstay of US electrical power output, coal and 100 times the {content}.25 per megawatt hour that go to natural gas, the two sources that account for over 70 percent of US power supply. Way to go for social engineering.

Considering our main energy source is oil and estimates for the time of peak oil production vary from a few years ago to ten to twenty years in the future, the fact remains that it's an eventuality that we will run out sooner or later. Without mechanized agriculture, the carrying capacity of the earth has been estimated to only be about 2 billion and change, so are we set up for a Malthusian catastrophe, or do you think that we will be able to compensate with emerging renewable energy?

Gravity is a natural force that pulls down, therefor it should be possible to get some energy out of it.

And heat is a free and limitless energy source, i think.

Has anyone looked into this???
If so what came of it?

And one type of nonrenewable energy source from the forest ecosystem. Or in near that ecosystem.

for example; cost, issues concerning the collection, storage and or transportaion of energy source, current infrastructure inadequate, low efficiency, political blocks. be specific

I'm doing some research and have trouble distinguishing the difference between these three types of energy sources.

So far, I have Conventional energy widely used/practical energy sources like oil, gas and coal. My assumption is that they're the primary 'standard' energy sources the world currently uses for their electricity and power since the industrial revolution.

I'm having trouble with the next two energy sources..

Conventional Alternatives, I put that at energy sources that produce less environmental waste and could be used to replace conventional energy sources. An example would be biofuels being used to replace oil/gas for cars. I guess Nuclear power could go under this energy source as it could be used to replace coal in North America but places like France have 90% of their cities powered by Nuclear - would this mean it's a conventional energy source for France and a conventional alternative to North America? I don't know..

As for Non-conventional energy.. I put this at energy sources that produce the least amount of environmental waste but are completely unpractical to implement. My example would be hydrogen powered cars because there is no current infrastructure to support Hydrogen fuel gas stations if consumers were to buy them.

I'm just purely guessing here - please share if you disagree or agree with my definition. Also If anybody knows what category other energy sources like wind, solar, and thermal energy belong to, I'll be super grateful.

110 litters of air will lift 550 lbs which equals 1 HP
Air bubbles are a constant 24/7/365 where wind is unpredictable,bubbles seem like an over looked energy source,dont they?
I have a secret!!!

I have to give a speech for a class where i have to persuade the audience to vote for a bill which requires all energy providers in the US to have at least certain percentage of its energy source from renewable sources. I need to know how much they use now, so that i have an idea of how much the required percent would be reasonable. If you know any representative who has proposed a similar bill, please let me know.

I am doing a report on alternative energy.......if you have any info on slar energy, hydroelectricity, geothermal energy, or tidal energy, it would be much appriecieted!!! im looking for websites, or online articles. i need to know how its gathered, if its renewable, posotive aspects to this energy source, negative a spects, primary uses of this energy source, is it more available in other parts of the world that others, is this energy source economical copared to fossil fuels, what impact it has on the enviroment, and is it a good alternative to fossil fuel.

THANK YOU!!!

Alternative enrgy, energy source.
