What are the drawbacks to using Wind Turbines or Solar Panels for providing all power to a home?

What are the drawbacks to using wind turbines or solar panels for providing all power to a home?

A. The wind and sun are not constant, so there would be times when no electricity would be generated.
B. The wind and sun are constant, so there would be plenty of electricity for the home.
C. Wind and solar power are inefficient and too expensive to use and maintain.
D. Wind and solar power are efficient, but they are not able to produce enough electricity for a single home.

again trying to help..again thnx 4 the previous………
nothing else…………but A.
NO COMMENTS ON THE OTHER OPTIONS….
except these there is another drawback…….its when your brother breaks the Solar Panel after quarrel with you……then no electricity will b produced………….hope this funny answer u liked……..its just to make yahhooooooooooo answer FUNNNNN…………

Greasy Rider: Two Dudes, One Fry-Oil-Powered Car, and a Cross-Country Search for a Greener Future $0.99 Is it possible to drive coast-to-coast without stopping at a single gas pump? Journalist Greg Melville is determined to try. With his college buddy Iggy riding shotgun, this green-thinking guy—who’s in love with the idea of free fuel—sets out on an enlightening road trip. The quest: to be the first people to drive cross-country in a french-fry car. Will they make it from Vermont to California in a beat-up 1985 Mercedes diesel station wagon powered on vegetable oil collected from restaurant grease Dumpsters along the way? More important, can two guys survive 192 consecutive hours together? Their expedition on and off the road includes visits to the solar-powered Google headquarters; the National Ethanol Council; the wind turbines of southwestern Minnesota; the National Renewable Energy Lab; a visit to one of the first houses to receive platinum certification for leadership in Energy and Environmental Design (LEED); an "eco-friendly" Wal-Mart; and the world’s largest geothermal heating system. Part adventure and part investigation of what we’re doing (or not doing) to preserve the planet, Greasy Rider is upbeat, funny, and full of surprising information about sustainable measures that are within our reach.

Radio-Controlled Helicopters: Radio-Controlled Helicopter, T-Rex, Proxflyer, Helicam, Ircha $9.16 Purchase includes free access to book updates online and a free trial membership in the publisher’s book club where you can select from more than a million books without charge. Excerpt: Radio-controlled helicopters (also RC helicopters) are model aircraft which are distinct from RC airplanes because of the differences in construction, aerodynamics, and flight training. Several basic designs of RC helicopters exist, of which some (such as those with collective pitch, meaning blades which rotate on their longitudinal axis to vary or reverse lift) are more maneuverable than others. The more maneuverable designs are often harder to fly, but benefit from greater aerobatic capabilities. Flight controls allow pilots to control the collective and throttle (usually linked together), the cyclic controls (pitch and roll), and the tail rotor (yaw). Controlling these in unison enables the helicopter to perform most of the same manoeuvres as full-sized helicopters, such as hovering and backwards flight, and many that full-sized helicopters cannot. The various helicopter controls are effected by means of small servo motors, commonly known as servos. A piezoelectric gyroscope is typically used on the tail rotor (yaw) control to counter wind- and torque-reaction-induced tail movement. This “gyro” does not itself apply a mechanical force, but electronically adjusts the control signal to the tail rotor servo. The engines typically used to be methanol-powered two-stroke motors, but electric brushless motors combined with a high-performance lithium polymer battery are now more common, as improved performance and decreasing prices bring these within reach of more people. Gasoline and jet turbine engines are also used. Common power sources are Nitro (nitromethane-methanol internal combustion), electric batteries, gas turbines, petrol and gasoline. Mechanical layouts include CCPM in all power sources, fixed-pitch electric rotors and coaxial electr… More:
