1 watt = 1 joule per second = 0.000239 food calories of heat per second
how much fuel is needed to get to the moon in a rocket
we can't change the position of the sun but the best position for solar panels is on open land high up on a hill and they should be black to absorb as much heat as possible to generate more pwer

Their exteriors are much colder, as they get little heat from the Sun. Deeper within their dense atmospheres, they are hotter. Jupiter and Saturn both have the ability to generate heat internally, which makes them warmer than they would be without it, but the mean temperature of Jupiter is still -162 Fahrenheit, and Saturn is -218 Fahrenheit. The clouds of Uranus and Neptune are colder still.
Well, yes, but the light is so weak that you won't generate much electricity.
1000watts
about 900
They do not generate enough heat to burn a book if cliped on and the bulb not close.
350 degree Fahrenheit of temperature.
80 Kgs
The formula you are looking for is W = E(squared)/R, W = Voltage (squared) divided by Resistance.

solar cells generate electric currents directly from the sun light
Do you mean Canterbury in NZ? I believe this hydro scheme is rated at 7.5 MW

There are many ways how electricity can create heat. For example, passing a current through a wire of high resistance (i.e. a resistor) will generate heat, though not much.
Assuming you got that number off an electric kettle it is because that is how much power is needed to heat the water. The number of watts actually measure how much energy the kettle is designed to use. Water is very hard to heat compared to other liquids(or to cool). So it takes a lot of watts to get the kettle to heat the water.
