I think energy from natural resources is the best energy. The solar panels being developed now are very promising. We have always used energy from water and wind. We need to focus on that.

Thanks for the clarification! I don't think that there's a single source of energy that matches all of those criteria.

Probably the cleanest energy (solar) is expensive to collect and not all that easy to get. For example, with our present technology, as far as I understand the matter, solar panels across the roof of a house in a developed country can't come close to covering the energy costs for that household. (Solar power is good, and we should use it, but it has its limitations.)

Conversely, some of the cheapest sources of energy (e.g. coal, oil, natural gas, perhaps even atomic energy?) are often the dirtiest and are limited in supply. Those sources will become more and more difficult to locate and to collect, and eventually (perhaps soon?) the cost of the collection may very well reduce or even outstrip the gain of the collection in terms of both financial cost and energy cost. For these reasons, among others, biofuels (fuels made from plants) have gained in popularity.

The previous posters are correct, I think. In the future we will probably be using a mix of energy sources and will probably be forced to rely much more on renewable sources. Your question certainly addresses an important topic, something that we will all need to continue to think about!

I would like to add that in order to answer the question "What is the best source of energy?" we would need to define what we mean by "best." If "best" means "very affordable in the short term" and "very available in the short term," oil and other fossil fuels will probably end up being the best source of energy. If "best" means "sustainable, with little concern right now about cost and current technological limitations," solar energy and other renewable sources will probably end up at the top of the list of best energy sources.

The previous posters make some very good points, but they don't mention atomic energy. More than a few highly developed countries (e.g. France and Japan) have been relying heavily on nuclear power plants for decades, and I can imagine that -- for all its risks, real and perceived -- atomic energy will continue to be an important energy source in the future.

I think the focus by necessity has to be more and more on renewable sources of energy. What I would like to see is more and more people investing in solar panels and wind turbines for their houses and communities to try and promote sustainability. Whether this will happen or not depends on our ability to stop our headlong course off the edge of the cliff we are currently heading towards.

Hard to know what will be used the most in the future because we don't know what sorts of technology will be able to become economically feasible.

For electricity, I think there will be a broad range of renewables that will be used.  I think there will be biofuels made from non-food plants and even biofuels emitted by algae.  I think there will be a great deal of use of tidal energy and wave energy on ocean coasts.

I do not think that any one of these will dominate, but I think that together they will constitute a major source of energy.

I can just imagine the day when we finally event technology suitable for non-renewable energy. Of course, it'll take years of planning and careful funding, but imagine it for the future generations, an insurmountable amount of energy for everyone to use. No one even has to worry about trying to find alternative ways.

What I mean about best is that the energy must be clean, easy to get for everyone, not of great cost and that it doesn't affect the environment.
