Like geo-thermal energy,solar power

Advantages:

- There are no carbon equivalent (CO2e) greenhouse gas emissions once the wind turbine is built, although some are produced in manufacturing and installing the wind turbines.
- Wind has a lower cost per installed megawatt (MW) of generation capacity than some other types of renewable generation (e.g. solar, biomass).
- Wind is a mature and established generation technology, which is widely accepted by energy utility companies (compared with emerging technologies such as biomass gasification/cogeneration, which have more technical risk).

Disadvantages:

- wind power still has a higher cost per installed MW of capacity than some conventional energy sources (e.g. coal, hydro).
- Power production is intermittent, depending on wind speed (this is also true of solar and marine renewable generation). This means that generation utilities have to either have backup generation (e.g. gas peaking plant), demand reduction systems (e.g. hot water ripple control) or hedging arrangements with other utilities in place to ensure they can deliver power to consumers and maintain the required power quality for the grid.
- Sites that make good wind farm locations (places with bare land and strong, steady wind flow) often are in remote places a long way from major electricity grid connection sites. This means there can be substantial added costs to connect generation sites to the grid.

Comparisons with Geothermal & Solar:
- Geothermal power production is a well established technology (over 100 years old) and can provide high levels of baseload (steady supply) power in large volumes.
- There are a limited number of sites suitable for geothermal power development, even in countries with plenty of geothermal activity (e.g. Italy, New Zealand, Philippines). Not all geothermal wells are suitable for commercial development because a combination of large reservoir, high heat and high pressure is needed to make power in most cases.
- There are companies developing more efficient geothermal technologies (e.g. Ormat) that allow smaller, lower heat or lower pressure wells to be developed.
- The direct heat from geothermal can also be used for industrial processes (e.g. woodpulp processing, timber drying and food processing).
- Geothermal power typically has large startup costs (tens to hundreds of millions of dollars) and for this reason is usually only undertaken by large energy utilities.

Solar:
- Solar has been used for around 30 years in commercial applications (e.g. backup power for telecommunications sites) but has only grown into the mass market in the last ten years or so.
- The cost of making photovoltaic (solar power) panels continues to drop with mass production and competition. Also, new technologies such as concentrating solar thermal and thin-film photovoltaic panels are increasing the choices available to users.
- The solar power market is splitting into two areas: utility solar plant (10MW+) and distributed solar, which includes small rooftop and community installations.

what are the advantages and disadvantages of solar, wind, hydro, and geothermical energy?

The advantages of solar, wind, hydro, and geothermal are that they are clean and renewable. Those energies are also ubiquitous meaning they are everywhere and widely available. The disadvantages is that they are expensive and have little output. At this point in time, we do not have the technology to harness these power sources to produce baseload generation. Fossil fuels are cheap and have dense output.

I need 6-8 advantages and disadvantages of using wind and geothermal energy. If you can help me, explain how to generate wind energy. THANK YOU

Wind energy is generated from wind turbines which are structuyres with blades that get presented to wind. The energy in the wind moves the blades which turn an electric generator.

Goethermal uses the heat in the Earth to het water making stem whih is used to turn a steam turbine which turn an electric generator.

Electric generators convert mechanical energy to electrical energy by the motion of loops of wire passing through a magnetic field.

Advantages of both:
Renewable/large source of energy. Wind is created by weather and the molten core of the Earth is huge.

Clean. No fuel is burned during generation of electricity. The energy required to build the devices is small compared to the energy generated over the life of the device.

Safe. Unlike nuclear, there is no hazardous waste or risk of raditation leaking.

"Free" – We do not import the source of energy from other countries which lowers our dependence on foreign oil.

No impact to food production – unlike bio-fuels, wind and geothermal do not burden our agriculture production.

Disadvantages:
Wind is unreliable. Wind farms are built in windy areas to increase the production. Since it is dependent on the weather – there is no way for humans to control it.

Wind farms are considered ugly – a blight on the areas where they are built.

Wind farms harm migratory birds.

Cost – currently the cost is higher per kWh to produce wind energy and geothermal. However, as the price of oil continues to climb and the world’s oil reserves are depleted, it becomes more attaractive economically.

Location – Geothermal and wine must be located at the "source" of the energy. The energy must be converted to electricity for transmission. Since many cities rely on oil or gas fired generation plants in their locale, the geothermal and wind are more supplementary than primary sources for electricity (nuclear and hydro-dynamic suffer the same issue. Since oil can be transported by ship and/or truck, and natural gas pipelines are all over the nation, it is easier to locate the generation near the demand).

what type of renewable energy is Wind Power?

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.

Leather and Jeans has a very good answer!! Thumbs up =)

I can hardly bother to write this since work has made me so lethargic and numb. I’ve been at my new job for 4 months now and I’ve realised I really hate my EXTREMELY dull job. It’s a good job working on quite high level civil service work, but it’s deathly boring…and I do mean that. I sit facing a wall and have no team members to chat to really..you could hear a pin drop sometimes. The only time I raise a smile is with the canteen staff or the security guys. It killed me sitting there today, it made me so lethargic I couldn’t find the energy to do anything I was so completely lethargic and I didn’t do the work properly. I’m not lazy, just disinterested and feel powerless with not enough responsibility. I’m 36 now and have moved jobs A LOT in the past (all office jobs) and this was meant to be the one that would allow me to settle down, but it will result in my depression returning as it always does in these jobs. I’m not lazy, I did 5 years in the forces and am more qualified than anyone I know, but I just get SO LOW in these jobs. I’m so annoyed with myself. I really really wish I wasn’t like this. People say ‘stick at etc’ and I know they’re right, but I can’t…today felt torture. I yearn to be outside walking and breathing in the fresh air and getting the daylight. At weekends I spend as much time as I can outside. The problem is that all my miserable work experience has been in offices, and I do have a couple of post graduate degrees too. I just can’t hack these jobs. I’ve quit a few call centre jobs which left me feeling like I was going mad and before that low paid run of the mill office jobs. This is a good job I have now, but I sit facing a wall and have no one within reach to talk to and then go home alone and get wound up all night by noisy neighbours.. I feel like I’m going mad. I moved to a new town 4 months ago for the job and feel deeply unhappy now. I know nobody in the area and have bonded with no one at work…it’s not that kind of work..really it isn’t. I feel I’ve messed up again. How can I feel motivated at work again? I just want to escape from this new job and new area and never ever set foot in another office ever again. I think I feel isolated being surrounded by 99% womnen too at work, – I have no male company and the women are nice, but I have nothing in common with them…they drive me a bit batty if i’m honest. I know it sounds crazy, but I get these very strong compulsions to run off and live in the wild or something..I get those thought a lot. When it’s really bad I just feel my position is hopeless and consider topping myself…I feel so trapped by myself…Why can’t I do what other people do? Can anyone help me??

I am very similar to you. Whenever I’ve held a job for a while, I start feeling trapped, depressed, and like i’m loosing my mind. I’ve taken medications before that helped, but overall didn’t solve the problems. They mostly numbed me out, so instead of hating my life, i floated through. It’s really not the way to live, and not a real solution.

You can change your work life to suite your mental needs. You can’t really change your personality and emotions to suit your work life.

I don’t know what skills or degrees you have, but maybe finding work where you’re outdoors more, around more people, or travel more (even if it means a decrease in pay) might be worthwhile. Who cares if you make less money if it means that you’re happy.

My experience with this:
I worked in IT. Stuck in an office all the time. I hated life. I’ve since started my own IT services company, so now I’m my own boss, I go to many different offices and homes to provide computer services. I meet and have befriended many different people, I work in many different places, and I answer only to myself (and customers). It is a drastic improvement. I have bad days like anything else, but it is NOTHING compared to the horror of being stuck in the same office, with the same people day after day after day.

I was wounder ing if you could do this for me beacuse my dad died a monthago and i have loads of homework and i have not even been through this but despite that i have to do it this is it:You are working for the government and have been given the assignment of finding an alternative fuel because Fossil Fuels will be running out in a month!!!! Your research project will consist of 2 parts:

1.Complete the table below showing the advantages and disadvantages of all energy resources.
2.You then choose 1 of the resources (NOT burning fossil fuels) and prepare a more detailed leaflet/newspaper article/presentation as to why we need to use that resource.

thank you

RRRAAARGH… I hate it when teachers give propaganda disguised as projects. What a crock of BS.

I’ll help you, simply because you asked nicely, and I’m bored waiting for boot camp (9 days to go! Woohoo!)

Geothermal:

Advantages:

Very little emissions, because the steam is generated through nuclear decay in the Earth’s core. The result is clean energy. Additionally, it can be done on a large scale because there’s a lot of heat in the core. The only question is how much is cost-effective to harness.

Disadvantages:

Geothermal energy requires a huge amount of maintenance. The corrosive nature of sulfur and other nasty materials that are found in geothermal vents requires constant upkeep to prevent the power plant from failing.

Also, geothermal energy is only cost-effective close to volcanoes, where molten rock is close to the surface. Placing it just anywhere would be extremely expensive to maintain. The fact that these power plants are near volcanoes means that if the volcano decides to erupt, everyone in the power station is toast.

If you limit geothermal energy to extinct volcanoes, geothermal energy’s potential is even more limited.

Fossil fuels:

Advantages: Cheap, powerful, and constant. The big three. Fossil fuels are the perfect power plant fuel, drawbacks excluded. That’s why everyone uses them.

Disadvantages. I’m not going to put quantity there, because our oil and coal reserves keep going up every year, and we get more efficient every year. The only people who are screaming, "We’re running out of oil" are morons who don’t realize that we’ve been worrying about running out of oil ever since we started using it. Every time we start running out, we develop new techniques for extraction and find more oil that was previously too expensive to extract.

Carbon dioxide emissions are only a problem if you’re worried about the crap that Al Gore is peddling. Yes, the Earth is warming. No, it’s not going to kill us all. In fact, it’ll lead to an end for world hunger.

Pollution is a problem if you’re using low-grade coal. No one likes living in a cloud of sulfur dioxide. The problem can be remedied if you use clean coal.

Nuclear:

Advantages:

HUGE amount of energy produced with a single power plant. Refined uranium is a very potent source of energy, and a pound of the stuff has more energy than a ton of coal. That’s pretty awesome.

Because so little uranium is needed to produce a huge amount of energy, there is almost a limitless supply of uranium in the Earth’s crust to mine. Uranium is one of the most common minerals in the soil, and current estimates show that we have around 12,000 years of power if we switch over.

No gaseous pollution. The only thing produced is steam from the cooling towers.

Disadvantages:

The problem is that once the uranium is used, you end up with a bunch of radioactive polonium that is useless and quite dangerous to human life. This stuff has to be disposed of where it can’t be disturbed by water (corrosion of its containers) and where it can’t harm anyone nearby. The best place would be in Nevada (Yucca Mountain) or Utah (somewhere out in the salt flats). Either way, transportation of such hazardous material is going to be expensive, especially if it’s being transported from somewhere like Maine.

Expensive measures have to be taken just in case there’s a meltdown. American power plants have what’s called a containment building, where even if the reactor melts down, the material is caught before it gets scattered everywhere, like what happened in Chernobyl. The result is something like Three Mile Island, where the reactor failed but no one died. It was very expensive to clean up, though.

Solar:

Advantages: The sun has a huge amount of power, and it’s free. Solar panels can be placed just about anywhere, and they produce no emissions. Also, because there’s no turbines being used, (the solar cells directly generate electricity) there is much less maintenance required.

Disadvantages: What if it’s cloudy? Nighttime? The sun is not out 24/7. How are you going to store all the energy required to run millions of homes? A bunch of batteries is going to be VERY expensive. Hell, they can’t even get a car to work on batteries. How are you going to power a city on them? The only way to power a city would be to have a backup generator… which would probably end up being coal or nuclear. In that case, you need to have two power grids – one for the solar energy, and the other for the backup. That’s prohibitively expensive.

Hydroelectric:

Advantages: No pollution, lots of power created for little cost, and it also doesn’t occupy any land that could be used to build something more desirable. Who’s going to want to build a house on a river?

I continued my post in the sources section. Damn Yahoo Answers’ character limit.

How is the energy wind power generated?

Just like Thomas Edison did it. Moving coils going through magnetic fields. OR moving magnets going through coils. The windmills usually travel slowly so there is a transmission that speeds up the shaft speed.
There are many different generating scemes but all involve systems that put 60 cycle power (most at 3 phase) back into the power lines. There are systems that shut down the windmills and face them correctly when the wind speed exceeds the design speeds for the turbines.

The economic cost associated to green energy such as solar, wind, waves energy has great impact on individuals and nation .
Individual can reduce paying energy bills by using wind or soloar power for electricity or heatings and states can be not aliened to others usual energy ressources such as petrole or nuiclear, they are no more dependant for others countries and can also generate national energy without high cost and clean not altering environnement. You can by yourself build wind power network by yourself and reduce up to 65 % your energy bills; goto : http://www.windpowercost.org and get free courses there.

The Pepper Grinder

Mommy takes us for a little treat,
To Epi’s sub shop we go to eat,
For a slice of pepperoni pizza.
A strawberry soda and a cookie.
The counter is covered in wreaths
of garlic and peppers
And they crunch loudly while
Mother, holding little hands still,
Is trying to order lunch,
But she’s never able to get them all
And so continues the crunch,
Crunch, crunch!
Of ruined peppers.

Slap!

There is a little crying
Though eyes are laughing
It didn’t hurt
And public is not the place
To make a scene.
Finally aunty takes us to sit
And the full length mirrors
Are shiny and clean
And we are such good
Little boys
Sitting with hands in laps
With big smiles
So very still
Until you look under the table
And see the greasy little hands
wind milling around and round
Smearing the mirror
And picking at leather.

Slap!

It didn’t hurt
But public is not the place
To make a scene.
We’re not too good at math
We never put two and two together
That the peppers
And mirror and leather
Might bite us later
In the seat
At home
Where they cannot reach
When mommy teaches
Such good little boys
How to behave.
But I guess I turned out ok
Mommy is dead
But a part of her is with me
And I don’t touch the peppers.

- tony
Lol, it really happened and it was only a few years later that my mother passed on. I consider this one of the valuable memories. I can laugh about it now and yet she instilled a valuable lesosn in my heart – to respect other peoples property.

As far as rhyme or meter, it is intentionally done without it as it is from the view point of myself as a child. I personally did not have a concept of rhyme or meter as a child.

You start off in rhyme then you go into free verse. It seems to be more of a short story than poetry. however, there is not enough to this to make me excited about it. If it’s to be a short story, then the moral of it needs to be stronger than; "boys got smacked by their mothers for being boys". or if poetry, the rhyme and meter needs to be consistent.
