Does Wind Power Create Greenhouse Gases

Richard asks…

why do we need eind energy?

Windmill Farms answers:

Probably u mean wind energy
Wind energy is plentiful, renewable, widely distributed, clean, and reduces greenhouse gas emissions when it displaces fossil-fuel-derived electricity. The intermittency of wind seldom creates insurmountable problems when using wind power to supply up to roughly 30% of total electrical demand (low to moderate penetration), but it presents challenges that are not yet fully solved when wind is to be used for a larger fraction of demand.

Susan asks…

Why are so many people climbing on the Wind Turbine wagon?

when they do not create energy only replace what the regular power plant puts out. do not save any greenhouse gases because the main power plants cannot be turned off and on like a light and must stay running only disengaged from the turbine until the wind stops, cause health problems, Audio ear problems, balance problems, the pressure change kills bats by exploding their blood vessels as happens when a diver acends to quickly and does not decompress, there fore stoping the bats from consuming about 1000 insects and hour opening the door to higher sickness issues caused by misquito’s, dairy stock milk reduction due to stray voltage which could come as far away as 50 miles, radar interference, are taller than the statue of Liberty, breaking radio and satelite signals. interfering with GPS signals, many contracts signed by Farmers sold to the Chinese? Where is the benefit. Any studies coming out in favor of these are not based on Scientific evidence, only studies done with 1/2 milliion dollar energy grants from the government?

Windmill Farms answers:

I totally agree with you. Wind turbines are not a good solution to our energy problems at the moment, in there current implementation. I think a much better solution to harnessing wind power will be devised shortly, perhaps in a large distributed network in existing civil infrastructure. I have always thought that if a whole city, would use something like piezoelectric wind harvesters (I will explain shortly), and connected them together across the grid, then perhaps a significant amount of power could be harnessed and supplement the power grid.

The afore mentioned piezoelectric wind harvesters (PWH) will consist of quartz fibers, integrated in curtains, blinds, awnings and as separate installations. When the piezoelectric effect from the bending quartz crystals is harvested (probably high voltage, very low amperage), via the specialized and currently being digitally prototyped, electrical harvesting mechanism, the high voltage, low amperage output could be transformed and added to the grid.

If many of these type of PWH enabled fabrics could be used in place of the current textiles in curtains and other furnishings, perhaps the collective power of these items could help with a new lease on wind energy.

What do you think of Pickens Plan?

http://www.pickensplan.com.

Put up a bunch of wind turbines and solar panels to generate electricity for the USA. Use Natural Gas to power cars.

This would:

Build plants and create jobs in the USA for building wind turbines and solar panels. Employ those who install and maintain them.

Reduce the need for foreign oil from the Middle East.

Reduce greenhouse gas emmissions. Natural Gas is very clean burning.

Boost the American auto industry if they see the light and start building natural gas hybrid vehicles.

Seems like a no brainer.

Windmill Farms answers:

The wind part is great. The natural gas vehicles part doesn’t make any sense for several reasons.

1) Converting all of our cars to run on natural gas would be a massive undertaking.

2) We really don’t have that much natural gas to begin with – around 3% of the global supply and already 25% of global consumption even before converting cars to run on natural gas. Very similar numbers to another fossil fuel – oil.

3) It would be more efficient to use the natural gas in power plants and then use the electricity to power electric cars.

James asks…

What are some advantages and disadvantages in solar powers?

Windmill Farms answers:

Some advantages:
1) Are beneficial for the environment

2) Do not damage the ozone layer

3)t is a renewable resource. We do not have to worry about the sun ever going away (after all, if it did, we would be dead). Although it may disappear behind a few clouds for a few minutes, disappear completely at night, or for hours during the winter, we can always expect it to come back in full force.

4)Solar power is non-polluting. Unlike oil, solar power does not emit any greenhouse gases or carcinogens into the air. Solar power is good for the environment (at least, it certainly is not harmful like other sources of power!)

5)The light and energy from the sun is free. In other words, once you have your solar lights or solar panels set up, etc., you are not going to have to pay to run them.

6) Solar cells require very little maintenance, greatly because there are no moving parts that must be maintained.

7)Solar cells can last a lifetime.

8) Solar power is silent powered. The methods used to find and extract oil can be very noisy. Even wind power can create a lot of noise. Solar power, on the other hand, is completely silent.

Disadvantages

The main disadvantage of solar energy used to be that it cost too much. But with costs plummeting all the time as technology becomes better this really doesn’t hold up anymore.

So really, I can’t find any disadvantages other than if for some insane reason you like paying through the nose by your energy supplier, with no control or influence on price, lurching from one energy price rise to another. You can minimise the impact of this effect and offset your costs and reduce your bills. You will be independent!

Hope this helps

Good Luck

Sandy asks…

How to heat a greenhouse without gas or electricity?

Ok, I have a greenhouse 10′x8′ footing and is about 8ft tall. Made of PVC pipe frame with one layer 6 mil plastic. There is a 6′x8′ concrete slab inside and pebble on the perimeter of that slab. I have one side connected to my bedroom sliding glass door, single pane. I live in Orange County, Ca where the temp RARELY gets below freezing at it’s coldest.

I would just like “supplemental” heating heating but I do not have the ability to use anything plugged in and I want to stay away from gas.

I’m looking for a great idea maybe having to do with heat storing or even efficient use of solar energy. This is only going to be used during the winter times to keep a “tropical” climate. I am going to add misters as a humidifier.

This is what I have though of and/or come across so far…

1) run a pipe to my roof, paint it black and force air through it and circulate it back to the greenhouse. Problem is, I need to move the air and powering any type of fan that is plugged in won’t work. I can use a solar panel to power a fan but the amount of energy may not even be enough to raise the temp a degree or two. (if anyone knows a good way to move air using only what nature provides, that would solve my problem)

2) Run a vent hose from my tiny attic. Problem is, I would have to cut a hole in the stucco… I am not an owner so this won’t work. I could attach to any out-put of heat from on TOP of the roof, but I am not sure there is a good enough source to tap into. (my clothes dryer is on other side of house, cannot use – to far to reroute the energy/heat)

3) I read somewhere that you can lay a bunch of hay and the composting energy can heat the area. This is a very messy Idea but it may work. But, I would rather not take up too much space inside the greenhouse.

4) Since I have PVC frame and plastic on outside, I would double layer the plastic on the inside and create an air pocket, but this is only good for insulation purposes really. The heat will dissipate to easily as soon as the sun drops.

5) Someone suggested to use a mass of hot water as a heat storage device. Problem is, takes up space inside the greenhouse and needs energy to heat and maintain heat in the water.

6) Use wind energy to power a small turbine to move air through pipes. No problems with this, except it is not all that windy where I live.

So far the most appealing way is by running pipes on my roof and painting them black, but the real question then is, how do I move the air?

If anyone knows of a good (small) fan that can be hooked up to use only solar energy… I might be able to make that work.

If anyone has any ideas on how to heat a greenhouse with nothing but initial cost, then PLEASE reply an answer. Even if it does not work, I may be able to modify a good idea into a workable, great idea!

Windmill Farms answers:

Use a small solar panel, battery and pc cooling fan to force the air through the black pvc pipe on the roof and circulate to the greenhouse, this should help with the concept.
