Energy development is the ongoing effort to provide abundant and accessible energy, through knowledge, skills and constructions. When harnessing energy from primary energy sources and converting them into ever more convenient secondary energy forms, such as electrical energy and cleaner fuels, both quantity (harnessing more primary energy) and quality (more efficient conversion to secondary energy) are important.\n\nFuture energy development faces great challenges due to an increasing world population, demands for higher standards of living, demands for less pollution and a much-discussed end to fossil fuels. Without energy, the world's entire industrialized infrastructure would collapse; agriculture, transportation, waste collection, information technology, communications and much of the prerequisites that a developed nation takes for granted. A shortage of the energy needed to sustain this infrastructure could lead to a Malthusian catastrophe.\nEarth by night. Many parts of the world will demand energy as their economies develop.\nEnlarge\nEarth by night. Many parts of the world will demand energy as their economies develop.\n[edit]\n\nGeneral considerations\n\nAll the energy we consume is generated by using the four fundamental interactions of nature: gravity, electromagnetism, the weak nuclear force and the strong nuclear force to create work. Fission energy and fusion energy are generated by electromagnetism and the strong nuclear force. In both cases the weak nuclear force provides significant energy through decay reactions immediately after (and during) the primary reactions. Most forms of terrestrial energy can be traced back to fusion reaction inside the sun, with the exception of tidal power, geothermal energy and nuclear power. Geothermal energy is believed to be generated primarily by radioactive decay inside the Earth[1]. Radioactive decay energy is generated by both the weak nuclear force and electromagnetic force. Tidal energy comes from the gravitational potential energy of the Earth/Moon system.\n\nMost human energy sources today use energy from sunlight, either directly like solar cells or in stored forms like fossil fuels. Once the stored forms are used up (assuming no contribution from the three previous energy sources and no energy from space exploration) then the long-term energy usage of humanity is limited to that from the sunlight falling on Earth. The total energy consumption of humanity today is equivalent to about 0.1-0.01% of that. But humanity cannot exploit most of this energy since it also provides the energy for almost all other lifeforms and drives the weather cycle[2][3].\nU.S. energy consumption by sectors.\nEnlarge\nU.S. energy consumption by sectors.\n\nWorld energy production by source: Oil 40%, natural gas 22.5%, coal 23.3%, hydroelectric 7.0%, nuclear 6.5%, biomass and other 0.7%[4]. In the U.S., transportation accounted for 28% of all energy use and 70% of petroleum use in 2001; 97% of transportation fuel was petroleum[5].\n\nThe United Nations projects that world population will stabilize in 2075 at nine billion due to the demographic transition. Birth rates are now falling in most developing nations and the population would decrease in several developed nations if there was no immigration[6]. Still, economic growth probably requires a continued increase in energy consumption. Since 1970, each 1% increase in the Gross world product has yielded a 0.64% increase in energy consumption[7].\n\nIn geology, resources refer to the amount of a specific substance that may be present in a deposit. This definition does not take into account the economic feasibility of exploitation or the fact that resources may not be recoverable using current technology. Reserves constitute those resources that are recoverable using current technology. They can be recovered economically under current market conditions. This definition takes into account current mining technology and the economics of recovery

Wow! That's quite a question!\nOkay -- let's assume we're dealing with an electric stove. The elements on the stove heat up and are in direct contact with the cooking utensil. That's conduction. Microwave ovens work by agitating the tiny little particles in the food, and this is what generates the heat and cooks the food. \nThe toaster works by radiation -- the element heats up and radiates heat, which then cooks the surface of the bun, bagel, bread or whatever. \nIt's difficult to measure the environmental impact of modern appliances against those of previous generations. For example, where does the electricity come from? Is it generated by hydro power, or by a fossil-fuel powered generator? Availability? Previous generations used a lot of wood. It was cheap, you could usually cut your own, and was readily available. But it generated a lot of smoke. Coal was even worse. Solar powered appliances (and there are a few around, such as water heaters and solar cookers) are probably the most environmentally kind, but they are expensive and, obviously depend on a constant supply of solar energy, sso that limits their general effectiveness. \nHope this gives you a few avenues to explore.

The first step to energy independance is to reduce to an absolute minimum.  Having electric wires coming into our homes, we have become used to unlimited energy availability.  Find ways to maximize efficiency and minimize the amount of energy required.\n\nThe only reasonable budget I've seen from someone installing a full off grid system was in a house which was far from the existing power lines.  The cost to run poles and wires was on the order of $15000.  That immediately created an option for solar / wind and off grid independance.  The home owner installed solar panels for heat and battery charging.  A wind turbine supplemented the photovoltaic system.  He budgeted energy consumption and purchased very efficient appliances.  In the end his total energy created was just slightly over calculated requirements.\n\nIf you are entering this project with dreams of living forever with free unlimited electricity you will be sadly disappointed.  The equipment and installation is expensive.  The amount of energy being created is greatly limited and you will have to cut back greatly.  You will learn not to leave the television on with no one in the room.  No more lights on in every room either.\n\nIt is a very positive project, and absolutely worthwhile.  I'm working on a small wind turbine project.  It will consist of a 800 watt generator mounted on top of an 80 foot guyed tower.  Right now it's tied up in municipal permits and other nonsense.  In the end I hope to generate about 10% of my household electrical requirements.  Payback time, assuming no downtime, maintenance or repairs will be about 12 years.  Clearly it is not a money saving investment.  I view it as a hobby to learn with and explore.  I could blow an equal amount of money in a few months on cigarettes or beer and have nothing to show for it in the end.  My justification for the money spent is to have fun with it.\n\nHave a look at the project as it has proceeded so far.  I have the wiring diagram, charge controller circuit, pictures of foundations, and so on online.  Contact information is there as well.\n\nhttp://members.rennlist.org/warren/wind.html\n\nGood luck with your project!

By using only nature things not electric things(only ,if they pllute the air,...) and by saving the nature.

Electricity itself does not pollute the environment. But very often, producing electricity causes pollution. Most of our electricity is produced by burning fossil fuels, that causes air and thermal pollution.

In the context of your question,\n\nA resource is a source of material or energy that may be consumed, changed, or dispersed to the point it is no longer easily usable. Examples would be copper ore, oxygen in the atmosphere, helium gas taken from oil wells, water, sand, or even soil. Anything we do consumes or utilizes some sort of resource. Breathing uses oxygen from the air. Copper is used for wiring and piping. Helium is used for scientific research and birthday balloons. Sand is used to make concrete. Water is used for drinking, irrigation, and generating hydroelectric power. Soil is used for growing crops.  None of these are exhaustive lists, just examples. \n\nOil: Oil is a mixture of organic compounds extracted from the earth by drilling. It is created from organic materials deposited in sedimentary rock that are altered by heat, pressure, and biotic processes to create it. \nOil is used to make gasoline, diesel, airplane fuel, plastic, shampoo, rubber, antihistamines, and many other products. \n\nNatural gas: It is an organic gas that is also extracted from the earth by drilling. It is generated by a similar process to that for oil generation. It is used to heat homes, make fertilizer, and some plastics. \n\nWater: Water is found in many forms, but mostly as either fresh or saltwater. Fresh water is used for drinking, irrigation, etc. Saltwater is not as useful directly to man, but is an essential part of our environment as the oceans both support food supplies and have a large effect on the climate. \n\nWood: Wood comes from living organisms- trees. Wood can be used for building many things, including houses. It is used for fuel and is the primary source of fuel in some parts of the world.

In any machine there is a way to put the energy inside and there is a way to take the energy out.The out put energy need not be the same type of  input energy.\nIn any machine as per conservation of energy the input and out put energies  must be equal.\n But what we speak of efficiency of a machine is the ratio of the useful out put energy to the input energy.\nNaturally this will be less than  the total out put energy. It follows efficiency is less than 100%.\nBut we can try our best to reduce the unused energy (not used for our purpose)to be the minimum possible.\n\nFor example in machines due to friction many energy is being lost as the parts are heated. But with out friction no parts will work. So  some minimum amount of energy has to be wasted (wasted according to us and not according to nature). \nA car rolls down the road because of friction and the same friction reduces efficiency. \nThe efficiency of an incandesant bulb is low because the useful  light energy is low compared to the input electical energy and most of the energy is wasted as heat energy.\nThe florescent bulb has high efficiecy compared to the ordinary bulb because less amount of energy is not used for our purpose.

It does utilize a natural resource but... 'effectively' ?  I don't think so.  We can't use it to power cities.  It's still quite expensive and just used as a supplement to our regular energy resources.

Daylight Saving Time also saves energy. The U.S. Department of Transportation show that Daylight Saving Time "trims" the entire country's electricity usage by a small but, significant amount, about one percent each day, because less electricity is used for lighting and appliances.

Absolutely you can save your expense by saving power.  If you turn on your speakers, more power ll be consumed from your SMPS. so definitely you can save your expense by shut off your speakers.

It is generally pretty difficult to store electricity, and it is also difficult to cope with rapid changes in load (the demand for electricity) on a distribution circuit.\n\nElectricity suppliers manage the distribution network by forecasting demand and by basically switching power station on or off, or adjusting their output, as required. So it is worth saving electricity because they can then just produce less. Some also store excess energy in things like pumped storage systems (there is one at Dinorwic in Wales - it pumps water up a mountain then later uses it to drive a hydro station).\n\nVery large power stations are much harder to turn off or even turn down, so when demand falls and supply is mainly due to these then yes, a lot of energy is wasted. Microgeneration is much more responsive.

Depends on what for.  Nuclear fission is great for generating electricity.  Biodiesel has lots of promise as a motor vehicle fuel (not to mention would be great for the US Agriculture industry).  Solar power can greatly reduce the amount of power individual homeowners have to purchase from larger providers (but the initial investemnt is expensive).  Probably a combination of Fossil Fuel alternatives would be better than adopting a single alternative replacement.

Solar power works-it is used in many places.  The question is one of economics, which underlies nearly every human activity, but is one of the least studied fields.  It is expensive, and energy-intensive, to make solar-powered electrical panels-which in any case only work well inbright sunlight.  Solar power is most useful for heating water in individual houses, but again, it isnt economically competitive with coal, oil, and natural gas.  In order for solar power to be widely used, a number of things would have to happen. 1) development of much better electrical storage (batteries, heat sinks, capacitors, etc) 2) either solar power generators would have to get much more efficient or coal, gas, and oil much much more expensive or 3) to concern with greenhouse gases and pollution rise to such a level that people would be willing to pay 5-10 times more for electrical power.

Photosynthesis generally takes light, CO2 & water and makes sugars.  These sugars are chemically converted in to food, propane, methanol, ethanol, coal, oil, wood and all the other fossil fuels and orgnic compounds on the earth, through natural, geologic, and/or manmade processes.  At every step of each process, energy is lost.  To gain usable energy, other than in biologic processes, requires burning something, and using the expansion of heated gases to create physical force (motion), or then using physical force to drive a generator to create electrical current.    \n\nWe do not currently have an effecient method of making electicity using incoming Solar radiation.  Current solar cells convert a small percentage of one section of the electromagnetic spectrum into electric current.\n\nHope this helps.

Define power.\nElectricity is the flow of electrons through a substance.\nIn the United States, electricity can be generated through coal/fossil fuel burning plants, nuclear power plants, wind(mills), and solar energy collection.\n\nIn fossil fuel and nuclear plants, they use the furnace and nuclear reactor to heat up water in order to turn a turbine, which spins around an electromagnet to generate electricity. There is much loss of energy through this process because much of the energy used to heat the water is lost through convection.  In windmills, the wind directly turns the turbine, so there is not as much loss, plus, it is a renewable resource.
