WHY IS THE SUN HOT?
The sun is hot because it is undergoing a continuous thermonuclear explosion. Sun is called because of a process called "nuclear fusion". Hydrogen fuses to form helium. The fusion releases energy, heat and light.
WHY IS THE MOON COLD?
Moon is cold because the part of the moon we see never faces the sun, but the other side which forever faces the sun is hot. Sun and other stars create thermonuclear fusion, which releases enormous amounts of energy - heat, light.
Moon is made out of rocks similar to that on Earth and gets all the light and heat from the sun.

HOW DOES ELECTRICITY GET TO OUR
HOMES?
Electricity plants convert the energy from the raw materials of the Earth into electrical current. This is done with the help of huge generators, which are driven by water, steam, or wind. Electricity is then distributed at a high voltage through cables laid in the ground or through overhead lines, on which often birds it on swarms. Substations then produce electricity, which finally comes out of the sockets in our homes: 230 volts alternating current. Fuses protect us and our property from damages.
