What might limit the use of wind as a major energy source?

Answer 1

Solar energy is not available when the day is cloudy.Wind energy is not available when wind is not blowing.

Answer 2

The primary limitation is public tolerance of the huge mechanism in the nearby field. Some turbine designs are hazardous to birds, and some are noisy while in operation. The easiest limitation to overcome is probably the efficiency of the generator motor and electric losses in converting DC to AC. Oh, and the fact that the wind never blows 24/7.

Answer 3

The largest obstacle is creating a system that actually will make meaningful levels of power. The current systems produce about 10% of what they claim they produce. The hope is that someday we may be able to make a wind system that produces more power then it takes to build. Then we will have true green technology. Current systems produce very little useful power because the usable winds are only between 14 and 30 mph. Above this we shut down, below we get no power. Even in this range we only see 8 to 10% of the rated power.

Answer 4

If harvesting wind energy via windmills, it could be harmful to birds sometimes if the windmills are in the bird flight paths, especially in the bird migration paths.

People also sometimes done like the whirring and swooshing sounds from the windmills which can be constant.

Some people don't like the fact that a windmill can "block their view of nature or the expanse etc.. but this one is a personal opinion of some people.

Answer 5

The disadvantage of using wind powered turbines is that they might kill birds in some places. If it is a matter of a single turbine, then the wind might not always blow in the specific direction needed to power the turbine. Keep in mind that there are always days that are not windy, although a sufficient battery should solve that problem.

Answer

They are one of the most expensive methods of energy generation in terms of cost per kilowatt hour, and only affordable because of enormous government subsidies which, of course, are then passed on to consumers throught their energy bills. They only produce a fraction of their rated capacity. They are completely dependent on wind and, so, do not necessarily produce energy when it is most required.

Answer 6

• Although biomass is a renewable resource, certain problems limit its use. Biomass crops take up land that could be used to raise food. Also, plant fuels such as ethanol are still too expensive to produce on a large scale. For now, biomass materials provide only a small part of the world's energy.
• Wind is a good resource. It's limitation, of course, is that the wind doesn't blow constantly. If you can select a high wind site, or get your turbines much higher in the sky (think of kites or balloons) then wind becomes more useful.
• Hydrogen is the perfect fuel. When it burns its only emission is water. The factor that limits its use is that it doesn't occur naturally and it takes almost as much energy to produce as it gives out. Because it is highly flammable it needs careful storage and delivery.

Answer 7

Turbines and generators in the wind machines create electricity.

Answer 8

Wind turbines take up a lot of space
