Wind Energy Advantages And Disadvantages

James asks…

WIND ENERGY PLZ ANSWEr?

give some advantages and disadvantages

Windmill Farms answers:

Wind energy can be harnessed and used as a source of power.
Wind energy can clear the local atmosphere of pollution.
Wind energy along with the uneven heating of the earth’s surface creates global wind belts.
Wind energy is a mode of transportation for seed dispersal.

Wind energy can cause great damage in tornadoes and hurricanes.
Wind energy can sink a sailboat.
Wind energy can delay aircraft departures and arrivals.

Robert asks…

Does anyone know anything about wind energy?

I am doing a project on wind energy and i need some more information on the subject. If anyone knows anything about wind energy or wind turbines i would be more than happy to hear about your ideas.

Windmill Farms answers:

Wind speed is measured (in knots) by the Beaufort Scale.

Renewable Energy – the most reliable source of renewable energy is water power, most especially tidal water power.

Here in London in Roman times and right into the early Industrial Revolution of the 18thC there were dozens of tide mills along the banks of the River Thames.
How did they work. A simple mechanism which allowed a massive wheel or set of wheels to rotate in the direction of the tidal flow and then to reverse as the tide in the River Thames changed direction. So efficient were these tide mills, that one, which still survives today, could be in continuous production of power to drive flour mill machinery for up to 16 hours per day.

Medieval tide mill found at Greenwich – where I live.

There is still one surviving windmill here in London, it dates from about 1800 and is at Brixton.

Charles asks…

what are some advantages and disadvantages of bio-energy?

please answer with as many as you can with as much detail as possible

Windmill Farms answers:

Bio energy means energy involving some kind of life (so wind/solar/hydro – power are not included)
i’m sure you know that but just to be clear.

There are many different types (and i don’t know them all by any stretch of the imagination)

Anaerobic digestion: it runs from any biological matter but mostly from animal/human waste (toilet waste i mean) and also from landfill drainage so it doesn’t take much energy to extract like oil or nuclear. It takes allot to build a plant though and it’s much less efficient in terms of making up the energy used to build it. However, it is sustainable and has many places of usage particularly near large farms.

Then there is combustion of wood or other bio matter which is preferable in terms of sustainable resource but not in terms of efficiency of combustion or distribution. However wood is more effectively used as fuel locally than oil which has to be transported great distances.

With natural gas there is are many positive aspects such as the conversion of methane (a very powerful greenhouse gas) carbon dioxide and water (CO2 still a green house gas but actually much less potent). It is less efficient as, say LPG, however again when harnessed locally it makes up for some of the lack in efficiency. That is to say because the LPG must be accessed, processed and transported from one of relatively very few places in the world.

In other words with my 3 examples, and i’m certain this applies to other forms of bio energy (sorry i don’t know that much about any others), it is not so much the efficiency of the fuel that is important but partly the sustainability but also the fact that biological matter is all across the planet but the alternatives are not and they take a great deal of unsustainable energy to access and transport. A new attitude towards energy and it’s distribution and implementation would make (in my opinion) bio energy at least a contribution to global energy.

Maria asks…

3 advantages and disadvantages for wind energy?

please..its for homeowrk.! PLEASE?

Windmill Farms answers:

Advantages:

1. One of the greatest advantages is that it is ample.
2. Secondly, it is renewable.
3. It is widely distributed, cheap, and also helps in reducing toxic gas emissions.

Disadvantages:

1. The main disadvantage regarding wind power is down to the winds unreliability factor. In many areas, the winds strength is too low to support a wind turbine or wind farm, and this is where the use of solar power or geothermal power could be great alternatives.
2. Wind turbines generally produce allot less electricity than the average fossil fuelled power station, requiring multiple wind turbines to be built in order to make an impact.
3. Wind turbine construction can be very expensive and costly to surrounding wildlife during the build process.
