Sunlight
The most reliable source of energy for life on Earth is the Sun. Solar energy provides the necessary light and heat for photosynthesis, which is the process by which plants and other organisms convert sunlight into energy. This energy powers most ecosystems and is essential for sustaining life on our planet.
Radiation from the Sun-it's been going for a long time!
Sunlight. It happened every day and was the source of all energy.

The fundamental source of energy on Earth is the sun. Solar energy is the primary driver of most natural processes and life on our planet.
It's not the most reliable source.
Most life on earth, gets there energy source from the sun, that is assuming that the majority of life on earth are autotrophs (plants). They get this energy by photosynthesising and getting a energy source called glucose, which is used in nearly all organisms on earth... they can then use glucose as a respiratory substrate, for respiration... Hope this helps :)
No. Nuclear energy is the most efficient in producing steam for use in engines. 15-20% of the energy in fossil fuels is lost up chimneys into the atmosphere, and is unusable. Solar and Wind energy farms cannot harness or convert effectively all the energy in the sunlight or wind and have much lower actual efficiencies. Fossil fuels presently are the cheapest and most reliable energy source available. Solar and wind energy are less reliable.
