My experience:

Oil and Coal are dirty and too big of a carbon foot print.

Natural Gas, the collection facilities and the pipeline are dangerous.

Nuclear: We no explanation needed

Wind Power: We are getting close, but what about the impact on the birds (no pun intended) and also the the impact on the scenery

Tidal Generation: No good because it will impact our beaches and sea life.

Solar: Scenery issues and it will also attract more heat and raise local temperatures

Hydro: they don't want to give up the land to create enough pressure and then even with fish ways in might impact the wildlife.

Mind you no arguments about putting in shopping plazas and mini-malls that use a lot of power.

To get power there is aa trade-off, why is it the Liberals expect no trade offs but want the use of oil to stop? What is their solution?

I need to know what is the best energy out of wind, solar, hydro, nucular, coal, geothermal ("heat"), waves or tides before tomorrow so plz tell me and don't say none of them are more good than the others cuz I need one and one only

Which of the following power sources are most likely to come from natural monopolies? Which could be st up as either as centralized power sources or as decentralized, soft-path sources? What are the advantages and disadvantages of each typo of setup?

a. wind turbines
b.hydroelectric power generation along a river
c. coal
d. oil
e.solar
f.nuclear

What is one environmental benefit that a place makes from switching coal to win power?

Not including the green jobs the free market has already taken into account.
Wind energy costs 25% more than coal. In essence our energy productivity will go down by 25%.
Whenever has productivity going down created jobs?
Do not give me the foreign oil, the only time foreign oil is used in energy production is for peeker plants. Wind can not replace that.
As an engineer I like the idea of power and all kinds of power. Also as an engineer I can not see a more expensive means creating jobs.

I am doing a science project on comparing energy sources and i can only find one similarity between coal and wind energy. i also need similarities between solar and coal.

Hello everyone,

I'm studying electricity in school, but I still don't have a firm grasp on electrical power systems and was hoping for some help. I have four main questions. Anyone working in power systems, please share your knowledge!

1. How do each of the various generation schemes (coal / steam turbine, wind farm, nuclear plants, etc) output power at exactly 60Hz? I understand the basics of how a electrical generator works, but I don't understand how they stabilized the output frequency to exactly 60Hz.

2. How do multiple generation points in the system synchronize their outputs to each other? How do all the different power plants and such dump power onto the grid together at the same phase?

3. I guess I don't understand the grid itself overly well. Could anyone explain the concept of the power grid? (for example, is it like multiple net contributors of power (power plants, etc) each acting similiar to batteries in parallel?

4. What happens to excess (unused) power? If a particular system has three 250MW power plants, but the neighborhoods they power only use up 600MW, what happens to the extra unused 150MW? I've heard that people monitor the power input/output and "adjust" the power output from the plants to match the consumers' usage. Is this true, and if so, how is this done? (shutting off generators, running them more slowly, etc). Also, if this is the case, what is done for power generation sources that cannot be human controlled (say, a wind farm; when the wind blows, it turns)?

Thanks in advance.

- More diesel genarators
- Natural gas power generators
- Wind turbines
- Hydroelectric
- Nuclear energy
- A central solar power system
- Coal
- Wave Power
- Growing crops to convert to Ethanol/Biodiesel to burn in a power plant

PLEASE explain why and talk about the pros and cons. Try to mitigate or solve each con. For example, if you chose solar power, is there gonna be no power all the time at night? PLS i need opinions.

For example, at one point we didnt know if coal can be used for heating and stuff.What tests would you perform to see if liquid X can replace coal? plz lets leave the economics out for now, just the experimental stuff for now. Please give details or links on how to carry out the tests. thanks so much!

how does a coal burning wind turbine produce energy.. i need it like in this 10 minutes. i got to give my homework in tomorrow and i need to got to bed:/

a They can partially reduce the need for coal and nuclear power.
b They will never reduce the need for coal or nuclear power.
c They are too expensive to be considered.
d They are still far off because of the technology needs to be developed.
e Until they can supply a large amount of energy, they should not be considered.

food
oil
coal
waves
biomass
wind
natural gas

b) each of the energy resources listed above can have its energy traced back to one source. What is the mysterious "one source"?

I understand we're trying to cut back on Coal and Nuclear Energy, and find other sources such as Wind... yet am unsure of the issue at hand? Does it all have to with Global Warming?

I especially want to know the Political Stance on this, and what your opinion is on it...

-Simple yet Detailed Answers Greatly Appreciated!

out of coal, wind energy, and solar energy, which is the best for producing electrical energy????

i need help by tonight! this is for a project for school tomarro! helpp hellppp pleasseeeeeeeeeeeeee !!!! i need help on that question with deatil and explanation! please and thank you!

i love you all who help me on this!

Can I have a wind farm in my front yard? Solar?
How about coal driven turbines in my back yard?
Can I have a razor wire chain-link fence up against the sidewalk to guard it?
Do I get any money if I put electricity out into the grid?
Oh and it's all in an urban environment.

replace coal, much less coal and oil???

Never mind that solar works ONLY when the sun shines and wind turbines only work when the WIND blows, and that there is NO way to effectively store large amounts of electricity....

A. When a hydoelectric dam is built, thousands of acres of nearby land are flooded.
B. The production of solar energy does not pollute the air and will require the manufacture and installation of new equipment.
C. Biomass is readily available and can produce emissions similar to that of coal.
D. Landfills are ofter owned and operated by business people who sell the methane to utility companies.

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.

Science Class Question: I had to choose four non-renewable energy resources used today, and pick one that wasnt a fossil fuel. I choose oil/petroleum, natural gad, coal and uranium

A windmill, and windfarm, takes energy out of the wind and converts it to electricity. Over time, and after lots of years of windfarms, we could have taken enough energy out the wind that winds would slow down around the planet. What do you think will happen?

(NOTE: back in the 1800's they thought there was infinite coal and oil and never imagined environmental issues with burning it, so this question may be a real problem).

Pickens' plan would divert natural gas usage from power generation to vehicle fuel, reducing reliance on oil.

Cars could run on natural gas. Yes. That makes sense.

Pickens' plan would increase wind power generation. Wind is an underutilized generating source. That makes sense.

But wind is a baseload power source and is not reliable enough to use for peak power.

Natural gas plants can be turned off and on more easily than other plants, and natural gas is expensive, thus it is used primarily for peak power - power generation during high-demand times, when you need a reliable source.

Thus, you can't replace gas with wind, even though they're both power generating sources, because they meet different market segments.

Yes we should build more wind capacity for baseload generation, but doing that won't enable us to divert natural gas from peak power generation to use as a vehicle fuel.

More wind power would enable us to increase exports of coal, which is great, though the green-types don't want to hear that.

But it doesn't solve the issue of dependence on foreign oil - other than a de facto coal-for-oil program.

Why don't more people see this?

Know-it-all, the cost to store wind-generated power would make it much more expensive, which kind of defeats the purpose - - at that rate why not just use nuclear?
Blackcat - wind can be use for power generation only if it is windy.

I'm thinking that they help conserve coal.

What else?

There are many utilities in the USA that now offer you the option to buy clean, renewable energy from Wind, Solar, Geothermal and Biomass instead of the normal Coal, Nuclear, Natural Gas, Hydro and Petroleum. If you had this option, would you choose it? Why or why not? And how much is to much of an increase for it?

I was curious how profitable a wind farm may actually be in comparison to coal. What is the pay back period, maintenance costs, etc. Assume ideal wind conditions, 30 year life, and industrial size turbines. Also, what is the most efficient spacing? I read somewhere it's 1km.

Thanks
