What do you think about the Energy consumption by humans in the future? What it would be?

Energy demand will keep on increasing. So there will be substitute sources of energy like solar cell and water. A lot of research is going on to make this alternate sources working and cheaper than the conventional ones like mineral fuels.

considering all the activism on saving certain species of animals, conserving enrgy and such that has been going on, i think more people will be aware of all the things that we have on earth that need to be saved.  although, i don't think life will get much better.  there will be a lot more abused children and neglected children, since hardly anyone cares what their children do anymore now, and those kids are going to grow up and do the same thing, because they have never been taught better.  i am curious what will be big in music.  techno maybe? i think if it hadn't happened already by that time, a nuclear war will be coming around then, because of all you hear about terrorism and nuclear weapons and the dangers today.

First of all, I think it is going to take a tad bit longer than a few decades to heat up the planet to the point of being uninhabitable. Go sit in yellow knife naked in the middle of winter and tell me then how long you think it will take to get the planet to the point hot enough to kill you.\n\nSecond, when we do reach that point, I think we will also have devised ways of living in hotter temperatures. I am thinking more of a bio dome type of surrounding. Or somehow force us to live underground. \n\nLastly, with things like the Kyoto accord helping, maybe we can turn things around with global warming, but only if we get rid of our dependency on fossil fuels.\n\nOtherwise, we are hooped.

http://www.darvill.clara.net/altenerg/solar.htm\n\nThis is a favorite source of future energy for many people, comforted by the thought that it is unlimited. But, quite the contrary is true. The Sun will exist for a long time, but at any given place on the Earth's surface the amount of sunlight received is limited--only so much is received. And at night, or with overcast skies, or in high latitudes where winter days are short and for months there may be no daylight at all, the sunlight received is very limited at times. Direct conversion of sunlight to electricity by solar cells is a promising field, but the amount of electricity that can be generated by that method is not great compared with demand. The conversion efficiency is low, about 12 percent with present technology.\n\nSolar energy in quantity requires huge installations. It has been estimated that an area of 60 square miles in relatively clear central Oregon would have to be covered with solar cells in order to meet the present electric needs of that State. About 10% of the cells have to be replaced each year. But the big problem is how to store significant amounts of electricity when the Sun is not available to produce it. That problem remains unsolved. The statement that "solar energy will not make next century's electricity" is probably right. And the end product is electricity--a very limited replacement for oil.

There are many possible futures,depending on what actions we\ntake-or don't take-in the present.Here are some...\n\n1. Global Warming is universally accepted by all as reality and not\ntheory when it's effects are fully felt-in the form of coastline flooding,a rise in the world's average temperature,famine.\nNone of the old people admit to the fact they had thought the whole thing was a story invented by foreign scientists to devalue\nthe U.S. economy. Noone will admit ever having voted for G.W.\nBush after accepting his brilliant opinion on global warming.\nEventually most people die as a direct or indirect result of the\ndamaged environment. The survivors move underground to escape UV rays and humanity becomes a subterranean race.\n\n2. Humans create AIs in the form of robots and computers,\nwho gradually take over the tasks needed to keep society functioning. After initial turmoil and mass unemployment suffered\nby countless now obsolete human workers,people adjust and\nenter into a new golden age of luxury and leisure. After they become useless drones,the AIs decide they are more worthy\nto govern the world and take over. Humans become extinct.\nThe AIs remember them much the same way as descendants\nof cro-magnon remember neanderthals.\n\n3.In the twenty-first century,after years of economic and political\ncompetition,the United States and China go to war. Their allies\ntake sides,the long-awaited Third World War finally happens.\nNuclear weapons are used with two possible outcomes here:\na) The human race proves it's stupidity and destroys itself.\nb) After limited use of nuclear weapons,millions of people are\nkilled,nation-states disappear from the world scene and there\nis a technological regression because of the global destruction.\nIt's the beginning of a new dark age,worse than after the fall of\nRome.\n\n4. Humanity solves global warming,effectively controls the use\nof AIs and avoids nuclear war again. Overpopulation becomes\nthe world's biggest problem,bringing birth control to the spotlight.\nHuge advertising campaigns urging people not to have more\nthan one child take place. Eventually it becomes law. There\nare huge riots,many people killed as the world adjusts.\n\n5. A few years into the future,a wandering asteroid hits Earth.\nThe impact destroys all life on the planet as if it had never been.\nThe rest of the universe doesn't even notice.\n\n6. Humanity solves all of the above problems and enters a period\nscience fiction writers dream of. Technological advances take\nplace. There are no flying cars,but cars are programmed with\nautopilot and GPS. Cures are found for diseases like cancer or\nAIDS. The human life span is extended to twice the previous \nextent. Space travel progresses-colonies are established on the\nmoon and Mars. The solar system is explored,and preparations\nare made for the first interstellar flight. The human race,in the\nthird millinieum,goes out into the galaxy.\n\n My favorite option is the last,of course,but I consider it to be the\nmost unlikely-with the possible exception of the asteroid scenario.\nThey say one is bound to hit Earth eventually but noone knows\nwhen. It could be tomorrow or a hundred years from now. Anyway\nthe future will be a difficult road and who can really imagine?\nWould a person from 1906 be able to imagine the events and\nadvances of the twentieth century?

In 20 years, the Internet likely won't exist in the same way as it does now.  We will be accessing all the Internet information through portable devices instead of huge klunky computers that are strapped to a desk.  Think of something the size of the PSP that is as powerful as the fastest desktop on the market today with complete wireless networking from anywhere.\n\nAlso, computers with wireless networking will be built into the dash of most cars in 20 years.\n\nOf course, that all assumes we eliminate our dependance on fossil fuels.  If we can't find an alternative fuel source to run our power grid, cars and transportation system, we may not need to worry about computers in 20 years as the oil may be drying up leaving no way to operate our economy.

Things will change and i think for good. Human beings will stop playing with nature.\n\nIn next 25 years the whole world come very close and there would not be any problems of race, cultures and terrorism as people will slowly realise that these things dont help a community to grow. \n\nScience will open new doors and we cant even think what all new things we'll see in next 25 years.

Just about all of the current problems will be gone, one way or another, and there will be new ones to replace them.\n\nTechnology will be light years ahead.  The more things advance and the more knowledge we have the more we are capable of advancing more rapidly.  The changes in the world in the last 50 years will be nothing in comparison to the changes for the next 50 years.

it will run out quicker i no that but,the energy we use electricity, gas ,petrol will not last foreve that is fact so it dosent really matter

Perhaps they will use the biological host's energy output to run. A human body puts out it's own energy supply.

No, not as they explained it in the Matrix. In the matrix energy is constantly lost to the robots and to heat, but there is no renewing source of energy. The movie claims that the humans feed on the dead; however, it is not possible to sustain, and then grow/reproduce, without some outside source of energy. We currently get this energy from the sun.

It would end up as heat. At least that is the usual place you say all the energy went when you can't otherwise account for it. Like where does the energy go when you drop a bean bag on the ground? Yell out loud? Turn on a light? slow your fall with a parachute? And on and on and on.

- new chimical technologies (less or different gravity and/or enveroment are required to reproduce some metals, for example)\n- extend energy resources\n- expand 'place to live' - Earth is going to critical poin of population in next 250 yrs (especially by chinees and russians ;) )\n- find biological life (for any progressive reasons, one of it genetics)\n- find new alien technology (fantastics, but possible)\n- test new nukliar space engine to explore space as much as possible ;)\n\netc.

Agree...Can you tell me what happens to peoples energy when they die?

um. dunno. maybe energy efficiency (everything else seems to be energy efficiency rated these days), safety and increased development cost.

in the world now 60%of the peope will be working 20%\nwill be watching tv and movies 10% will be eating 9% will be sleeping but one fool will be reading this -----------       world data according to UN\n                             have a nice day

A method for making really cheap solarcells from sand and a way to transport the elctricity the generate without any loss. The amount of energy that falls on the Sahara during a year could cover the worlds entire energy needs 50 times over even using standard photocells that convert only a few percent of the light to electricity. With such an abundant and cheap energy source we could replace ALL other energysources as electricity can be converted to any other form of energy and fuel. We could even keep gasoline cars because gasoline could be manufactured from CO2 (from the air) and hydrogen (from water). There would be alot less pollution if I could invent these things.
