Most of the energy used on Earth ultimately comes from the Sun; the two major exceptions are:* Tidal energy - here, the energy comes from Earth's rotation. * Geothermal energy - here, the energy comes mainly from radioactive decay in Earth's interior.

For us here on Earth, the prime source of energy is the Sun.
Energy from the sun travels to the earth's surface is brought here by electromagnetic radiation. Once the radiation reaches the planet, most of it is converted to heat.
No, the sun does not do work on Earth in the same way that we define work in physics. The sun's energy, in the form of sunlight, fuels processes on Earth, but it is not performing work in a mechanical sense.
Energy from the sun travels to the earth's surface is brought here by electromagnetic radiation. Once the radiation reaches the planet, most of it is converted to heat.
The sun gives energy, in the form of heat and light.
Not all of the light from the sun makes it to the surface of the Earth. Even the light that does make it here is reflected and spread out. The little light that does make it here is enough for the plants of the world to survive and go through the process of photosynthesis. Light is actually energy, electromagnetic energy to be exact. When that energy gets to a green plant, all sorts of reactions can take place to store energy in the form of sugar molecules.
The matter of the food passes in a cycle; the energy does NOT. The energy comes from the Sun, is used here on Earth, and most of the energy is eventually radiated out into space. There is no cycle there.
Shorter nights, actually we prolly wouldn't be here at all...
It takes place on Middle Earth, which is not actually here. In it's own canon it is in the present.
The energy from the ocean is the major recipient of solar energy. And in turn, the energy from the ocean is also the major source of energy here on earth. Ocean energy takes three major forms: wave energy, tidal energy, and thermocline energy, popularly called ocean thermal energy conversion (OTEC)
