Three possibilities: Petroleum (23%) + Natural Gas (30%) = 53% or Natural Gas (30%) + Uranium (nuclear energy) (33%) = 63% or Petroleum (23%) + Uranium (33%) = 56% A forth is possible if you consider: Uranium (33%) + Renewable energy (8%) = 41%
Fossil fuels, nuclear, hydro are the main ones, as in the US
solar energy provides a heat source for all living things on earth. we also transfer solar heat into electricity and other types of energy, using solar panels. however, only a portion of the suns energy makes it to earths surface because the ionosphere reflects some of the rays back into space. only half of the incoming ratiation from the sun makes it to the earths surface.
Because the cheap way - burning fossil fuel - has already used up more than half of all the fossil fuels that exist on this planet.
Since momentum is proportional to the velocity, half the momentum means half the velocity (and therefore half the speed). And since kinetic energy is proportional to the SQUARE of the speed, half the speed means 1/4 the kinetic energy.
Every 2 and a half minutes you gain 1 energy until it goes up to your maximum energy. You can also get energy by getting certain magical coins, which also increases your maximum energy.
Binding energy. and some is even stored in particles, such as the neutron which has a half-life of about ten minutes before it disintegrates with the release of energy.
gas and oil
Canada generates a great deal of electricity. It also has oil, natural gas and coal.-------------------------------------------------------------Renewable energy (from the sun, wood, hydroelectricity, wind etc)Fossil fuels (Coal, Gas, Oil, Tar sands etc).
Electric power energy provides about half of the total energy of the United States.

6 and half
It means there is no alternative energy source that can ween humanity off of fossil fuels. Which is presently true, however, given almost every developed nation is pooling their resources to replace fossil fuels, that isn't a timeless answer. Before the latter half of this century, gasoline and every other form, will or begin to exist only in history.
I think you mean Energy. No, the amount of energy gets cut in half(I think half) every time the energy is transferred from organism to organism. Thus plants get 100% of the energy from the sun, herbivores get 50%, level one carnivores get 25%.
It takes half of the food you eat and burns it into energy for the plant or animal it can be found in animal cells or plant cells.
It is half the hot of the sun
It divided Canada in half, Upper and Lower Canada.
The major antagonist of Half-Blood Prince is Draco Malfoy, as he provides much of the book's conflict. Severus Snape also plays a major role as antagonist, particularly during the end, and it is Voldemort that ultimately fuels both character's actions.
