Everybody talks about solar and wind power, but is it enough?

Get *the* Best Wind & Solar Pak, ever, Easy Earth Energy.... Let me know how you like it!

It seems to me it’s an easy thing to figure out how much KW the country needs and then see how many windmills and solar panels we need to generate the power.

Pickens says he wants to generate 22% of our electric power with wind. Is this feasible?

Does anybody out there know of any real data on the subject. Sure the polit’s all talk a mean fight but how many wind mills will we need to serve the power needs of the country?

There was a study a while back that siad that taking something like 2% of the land in Nevada and converting it to solar would be enought to power the Country. There’s als ample evidence that theres more then enough wind around the clock in certain areas toi give 24hr power. It’s all about money though!

Can wind power pay my electric bill?

Can I place a wind generator on my property that only converts dc into ac and runs it back into the grid?What i mean is can i do it without using a bit of the electricity myself.No Batteries,no connection to my power other than sending it back into the grid.

In India, we indeed have this kind of scheme by companies like Suzlon & Enercon. These guys will do a survey on your plot & if found suitable, will install a machine themselves. As a plot owner, you will be entitled for a handsome monthly rent. All the interconnection issues with state electricity board/grid will be handled by these corporations. I think you should check for similar schemes with your local power generation company.

I have a few questions about wind power?

Well, I don’t know much about wind power and I was wondering if I could go completely off the grid with wind power, or do I need to have a backup like solar? How much would it cost to buy a wind turbine and have it installed? Since I’d be making electricity on my own land, would it be free? Can I use wind power for heating my home?

Sorry it’s so many questions.
I meant once I install it, would I get electricity free?

Hey Piper, Kristen is quite right on the numbers. We power our entire home with wind and solar power, and we have made plenty of mistakes. If you want to run everything, you will need a herculean sized wind plant, maybe something on the order of 10 kilowatts or more. Ours is a 1kw, but the solar does most of the work here, even though it is more expensive. The question you have to answer first is am I trying to save money, or do I want to get rid of the power company entirely. To cut down your energy bill, I would suggest a wind turbine direct to grid tie system. The wind plant produces whatever power it can and dumps it in your home, if it’s more than you need, it sends the rest out the grid line, and your meter spins backwards. Problem is, if the grid goes down, your wind plant shuts down too, it has to have someplace to go all the time. If you want your own source, you have to have battery storage, and a larger plant, then you are spending more money up front for equipment, but if the power goes out, you probably won’t be aware of it. We have the latter system, and twice last year it provided us with power when the entire county was without, hard to put a price tag on that.

My suggestion is you do some reading for a while, start with Home Power Magazine, then check out the library. Our home was actually featured in Home Power twice in the past, use their search engine and look for, "small system first." You might decide not to get involved, and that’s fine too, but at least you will be well informed. Take care, Rudydoo

Anyone know any ideas on Wind Power?

Ok for my 6th grade show case I have to do this thing on wind power and I need help and ideas on any type of expierment you could think of. Links would be helpful!!

Thanks!
6th grade level please!

Take a personal fan (like one of those ones from the dollar store), replace the blades with much larger ones made from cardboard or thin plastic packaging, then link the electrical leads from the motor to an LED and a resistor. Turn the blades and the LED lights up.

Consider at least three of the following alternative energy resources?

Nuclear
Solar
Wind
Hydro
Wave
Geothermal
Biomass

Determine and compare the advantages and disadvantages. Then, decide which type of alternative energy resource would be best used in your area of the state or country.

solar, easy to come by, plentiful.

hydro, easy to set up, used for years, some areas dont have it

wind, easy to come by, used for years, some areas dont have it

geothermal, some areas dont have it

wait..am i doing your homework here?

wind power??????????

We have a lot of wind here in the Midwest US. I was just wondering why the heck we don’t have more? I am very concerned about conserving fossil fuels and the environment. I think that we shoud decrease our fossile fuel usage by about 40%. It’s a big stretch, but with new hybrid technology coming soon. and with exploring alternative energy sources. How can I write a letter convincing the government to make more wind plants even before the presidential election?
thanks,
Sam

Is this an "Epic Nightmare"?

I recently had a dream that played out exactly like a movie; it had a beginning, climax, and conclusion. The only thing is, i have never seen a movie at all similar to this and it was the scariest thing I have ever experienced.

The characters in the dream consisted of my parents, some friends, and a few celebrities from a comedy.
It starts out with all of us ^ going to an old warehouse to help clean it up and renovate. the warehouse had a separate "safe house" that was our base camp, so to say (brightly lit, colorful quilts, cottage style). this is where we were protected and could sleep, eat, ETC.
When we enter the huge warehouse, the doors get locked behind us. There is no way of getting out.
Inside, the warehouse is dimly lit (black and grey are really the only colors). It looks as if all the walls and floors are torn out. all that remains are about 5 stories of concrete beams vertical and horizontal. the ground seems to be a very soft dark-grey dirt-sandly floor.
It takes a moment to adjust to the surroundings. and then i notice tons of figures slightly moving in the distance and then on the concrete beams above and surroundings us.
the figures are all the same: grey, dead (i think), and identical. they have the human physique, but are different: monstrous, evil.
it becomes apparent in a second that we have to fight and kill all of them. So we start.
Its extremely tiring and strenuous, from climbing up and running on beams, to jumping down a few story’s onto the ground, only to realize running becomes even more difficult because of the sandy soil. the fighting continues. the adrenaline from it all almost creates a mind numbing power, yet terrifying in the same instant.
I distinctly remember running on a concrete beam a couple story’s up, and the creatures surround me: one crawling up a beam from ground level and almost grabbing a hold of my foot. another one in front of me in the direction I’m running. and a couple more chasing me from behind and above. I was running as fast as possible to the far end of the warehouse where i would have a better attacking position. i could feel every muscle in my legs, arms, and back expand and contract with my heavy breathing. my heart was sluggishly beating in my ears so loudly i could barely hear anything else. yet it was quiet. the creatures moved so swiftly they didnt seem to make any noise execpt that of distant nails scratching on a hard surface.
i reach the other end, jump down to the ground and stop. the creatures all jump down to a crouch on the floor and star walking towards me. i want help but there isn’t any(its just me in this scene, no other characters are around me at the moment or they are far off and i cant see them). i decide to plow them down by running towards them and through their masses. this seems to work and i excape.
this is the end of the 1st "work day". we all exit the warehouse into the "safe house" and eat and sleep.
i had a dream within a dream. a nightmare. while i was a sleep in the dream i dreamed that i was getting watched by the creatures and kept wondering why they hadn’t killed me yet. i wake up from my dream inside my dream and remember im in the safe house.
the next day is filled with fighting once again. but all i do now is run thru and plow through all the creatures. i am somehow killing or freezin them this way and the other characters come and get the bodys to "disembody" so they dont wake up. thiswas extremely disgusting, but all i remember are some stray grey hands lying on the floor. >_<

After a while of this i remember going up to my parents, saying i was tired and wanted to know when we were going to be done. at that moment it seems that we are finishing up the last of the creatures and we are somehow allowed to exit the warehouse.
across from the warehouse is a run down single story building with a flat roof, paint chipping off, and broken windows. i remember this building getting called slater mills. and in my dream it was an old gentlemens club from the 1800s that had a tragic fire killing hundreds. it hasnt been used since (i have never been there but im pretty sure its not what it was like in my dream). it seems like someone is explaining why there are those creatures in the warehouse by saying the building across the the warehouse ("slater mills") is haunted.
so we all begin our trek back to our own homes. the dream begins to wind to a close. the last thing i see is not from the eyes of my character in the dream, its just a small veiw of inside the warehouse. something scurrys across in the distance, leaving the dream open ended, but with a definite conclusion. the creatures are not all dead yet.

then everything goes black and i wake up, paralized with the fear of the dream and scared that the creatures are in my room.

WHAT DOES THIS MEAN?
i have had reoccuring dreams and falling dreams and random dreams ect, but i havent had one this intense and looooong. i’m still freaked

Those monsters equal worries and fears, and your family seems to be fighting them off together.

Dreams are not real, the only mean something, much like a painting of something fantastic does.

How efficient is wind power? Does it cost more than burning coal?

Is it economically efficient to have wind power as your source of electricity?

They are as efficient as the average generators however, air being the sorce of energy, besides maintenance, it’s free and environmentally friendly. Calculate your maintenance and compare it to your electricity bills.

Why do new houses not use wind power for electricity?

if were all supose to be going green,then why do all the new houses not use wind power! that will kick globle warming up the…..neck

moslty cost.

plus here in texas we’re building new solar collector array power plants. It claims 100% efficiency, 100% self sustaining, 100% clean (water, salt, and sunlight) 100% available all of the time (clouds and night time don’t effect it) and can power 400,000 homes. (due for completion in 2012)

heres one in Euroupe.(its only 11mw texas will be 300mw)

thats real sunlight

with wind you need a large amount of fans, constant winds all day every day, and an alternate power source for when there is no wind. Plus they are expensive.

regular solar, plus a few fans, plus underground temperature exchanges are the best ways to reduce your electrical usage to almost 15%, yet can get into the $100,000 range fairly quickly.
