      Wind or solar, depending on your location. They both rely on the action of the earth, and when you use the energy you take advantage of processes that would otherwise go completely to waste.

      The other good thing about both is that they’re becoming more available to a wider market now. Solar panels are reducing in price, and you can get decent ones in the $15,000-30,000 range. Obviously that will take a little while to pay for itself, but if you really want to go renewable, it could be worth it.

      You can also buy wind generating turbines for your house, for similar prices.

      One other option I would look into if you or anyone you know has the time and technical know-how is DIY solar and wind projects. There are a large variety of diagram/blueprint products that show you how to do these projects at home, check my source for details.

      When battery technology gets there, nuclear will be the way to go. It is far and away the cheapest per kilowatt-hour right now, even when plant construction, dismantling, and waste disposal are considered. The only shortfall now is that it has limited use in the transportation sector.

      It’s hydrogen via ammonia from wind and solar energy + biofuels.

      –Hydrogen via ammonia solves some problems of wind and solar energy. One of these is it solves the great problem of using wind and solar energy in the transportation sector… Etc…

      –Biofuels are the best alternatives but they are costly… and cannot satisfy the fuel request of all the world(China + India would can need several billions of fuels if they want to use cars like civilized people) so biofuels would become valuable fuels… However I think they can be produced in large quantities…

      you can never find an energy source which lasts for ever and doesn’t produce ANY pollution but the ones which last for a long time and have less pollution are : wind, Geothermal, hydroelectric and Solar energies.

      Wind. It is a consistent source of energy since it is caused by the rotation of the earth and the heating of the oceans. Since neither of those events seem to quit, this source of energy is extremely renewable.

      New technology utilizing vertical blades with a large surface area contained within a cylindrical shape has been shown to be highly effective in generating energy for less material and cost.

      Well, it depends on where you are. If you’re by water, hydro-power because it’s right there and waiting to be harnessed.
      If you’re in a place that gets steady wind, then of course, wind-power, it’s completely clean and it’s not like we’re going to use all the wind in the world any time soon.
      If you live in a place that’s far from water and not windy, and sunny all the time, then solar power.
      Really, there isn’t one specific answer, it all just depends on geography, you utilize what you have.
      Also, each really has a draw-back. Hydro-power plants can be destroyed completely in floods, and they’re expensive to replace. Wind-power is powered by those little wind-mill like things, and when they go haywire (or the plant gets greedy) and they spin too fast, the blades can cut the tower they’re mounted on an that leaves some very heavy debris. Of course, solar power doesn’t really do much at night.
      Also, don’t forget nuclear energy. When you study it enough, you’ll find that it really isn’t as bad as it’s hyped to be. Of course, nuclear energy sounds scary, since it can be associated with nuclear bombs, but it’s really safe. I just wouldn’t use it to power cars anytime soon, lol.
      But anyway, those are all the non-polluting sources of energy I can think of, but for curiosity’s sake, most people will still agree that gas and ‘polluting’ sources of energy are still the most efficient because we’ve had enough time to work with them that we know exactly how to make the most out of them. I can’t remember the numbers offhand but you can use a lot more of the energy harnessed from gasoline than from any of our other power sources. But, give it time, and we’ll be able to use more of our non-polluting sources than we ever thought possible.
