Which is more efficient? wind power or solar power?
Question:
Answer:
Good question. Wind power derives from solar power (differential heating or cooling of air masses). The real question is how efficiently can wind or solar power be captured. Solar power exists only 12 of every 24 hours and also depends on cloud cover. Solar power can be readily captured efficiently as heat energy in a green house (or a closed up car sitting in the sun). Solar power can be captured using photovoltaic cells but they are not highly efficient (yet). Wind power can blow 24 hours a day in select locales and the velocity is higher at elevations above the ground. Also wind turbine blades are far more efficient (exponentially) as their diameter increases. Therefore, large-blade wind turbines on high towers are relatively more efficient (capturing energy from currents in large moving air masses) than a solar collector that depends on the limited surface area of the device. There are solar collectors that use a field full of mirrors that all focus on a target (collector) and they can capture great amounts of pure high temperature (photon) energy.
WIND!
solar power is more efficient as wind power is due to solar energy
wind
it would depend both of them have flaws. Solar pannels abosrb energy from the sun. but if there is no sun to absorb then it doesnt work.
Wind pannels work through wind,but I think it is more efficiant than solar pannels until they find a way to make them abosorb for sunlight.
hope it helps a little.
OK, the answer to this question is 42. But the answer doesn't do much good if one doesn't know the real question. On the moon, it is pretty clear, since the only "wind" is some particles from the sun, wind power is impractical so only solar remains of the choices given.
On earth it is much less clear, is efficiency; power per dollar spent on infrastructure, per unit area of the installation, the percentage of the theoretical power available that is actually recovered or what? No matter what criteria is used for "efficiency" it will depend on the location, wind and sunlight varies quite a bit in different areas
Depentds on where you use it. Where nornally there is heavy wind (like sea side, large vast area etc), wind power will be more efficient. And normally in the tropical area the solar energy will be more efficient.
But if the both are available in the same quantity, the solar power will be more efficient, becasue in these types of plan normally there is no mechanical moving parts, which is there in the wind power energy. So in the wind power plant, there will be some mechanical loss.
We cant say that solar energy is efficient than wind energy or energy from wind is efficient than that of solar. This depends on the physical condition like place and the weather of that particular place.
If the weather is cloudy and windy than we will prefer to get energy from wind but if the weather is hot just like the weather of deserts, we will prefer to get energy from sun.
Wind power,because it is cheaper than solar power
With no moving parts, I'd say Solar power.
