Q. What energy did people use before modern times?
Before the industrial revolution, our energy needs were modest. For heat, we relied on the sun—and burned wood, straw, and dried dung when the sun failed us. For transportation, the muscle of horses and the power of the wind in our sails took us to every corner of the world.
Q. Can a human control electricity?
Originally Answered: Could a human control electricity? Yes. I — for one — can switch the light on- and off any time I want to, which more than qualifies as “controlling electricity”. After all “controlling electricity without tools” wasn’t part of the question.
Q. Can humans make lightning?
Almost all of that kinetic energy becomes more heat, but a very, very small fraction becomes electrical energy. It is entirely possible to create static electricity, and even lightning using this method. Artificial lightning (in miniature) is regularly created in places like NEETRAC at Georgia Tech.
Q. Can humans control lightning?
While humans have been placing lightning rods for centuries to increase the probability of striking in a certain fixed point, its path can not be controlled.

Q. What is bigger than a gigawatt?
A kilowatt (kW) is 1,000 watts, a megawatt (MW) is 1,000 kilowatts, a gigawatt (GW) is 1,000 megawatts, and a terawatt (TW) is 1,000 gigawatts.
Q. Why did they say gigawatts?
“I need a nuclear reaction to generate the 1.21 gigawatts of electricity I need”. But he pronounced gigawatts as if it were spelled with a “j”, as in jigawatts (or jigowatts). I always figured that the word “Jigawatt” was made up just for the movie and meant to sound like a really large amount.
Q. How much does a GWh cost?
Today, the average price per watt is about $3, according to a recent report from Berkeley. A 1.4 GWh array that costs $1/W to install would cost $1.4 billion.
