they are nonrenewable resources.\nonce they been used once (burned) they finished with and cannot create anymore energy.\nThe world has a limited suply of these nonrenewable energy sources left.\n\nrenewable sources woud include solar (sun) wind and water power as these will never run out

There is no such thing as non-renewable energy.  Energy is simply converted from one form to another and never actually gets 'used'.\n\nThere are non-renewable SOURCES of energy however and other answerers have pointed these out.\nHydrocarbons, like coal, oil and gas are considered non-renewable because once you have converted their (stored) chemical energy in to heat energy by burning them, you will have to wait several million years before the energy is stored back in a chemical form for you to burn again.\nWind power is considered renewable since wind is a form of mechanical energy which is converted thermal energy from the sun.  We use wind turbines to control the mechanical energy of the wind and convert it into electrical energy.  The sun provides more thermal energy, which makes more wind and so the source of energy is renewed on a useful timescale.\n\nMost energy on Earth comes from the sun.  Wind is driven by the sun as I have explained.  Solar energy is obviously sun powered.  Chemical energy sources like wood, coal, gas, etc also come from the sun since plants capture the solar energy and store it in their structure as chemical energy.  This same energy is what is released by burning.\nThe most notable source of non-sun derived energy on Earth is that of the tides.  Gravitational effects between the Earth and the moon (alright, and the sun a bit) cause the tides.  Gravitational energy converted to mechanical energy.  We can use this as a renewable source as well.\n\n<flight of fancy>\nIt is theoretically possible to have so many turbines extracting energy from the wind that there isn't enough left over to keep the winds blowing, which would have rather a startling effect on regional climates.  Turn the turbnes off however and the sun would soon start things up again.\n</flight of fancy>

oil is not a sustainable resource, so it will not last forever. \n\nSustainable resources, like sustainable agriculture, and sustainable development is  a way that we can configure human development a society in such a way that it does not compromise the need of future inhabitants of earth, this includes not just your children, by your childrens children and so on. I have included a link on sustainability it is packed with information and tons of resources to learn more about why it's essential to our existence. People are getting together everyday in this country (and with other countries) and around the world to create and improve sustainability.

I am guessing you are asking about environmental conservation.  Certain natural resources are limited.  If we use them wisely, then they will be available for a longer period of time.\n\nThere is a limited amount of oil in the ground, for example.  If we use it up, we will not have it to heat homes and power vehicles.  One way to conserve, would be to find other ways to heat homes and run motors.  Solar power, wind power and now biofuel are ways in which people are trying to do this.  Another way to conserve would be to use less heat in our homes and find other ways of travel, instead of cars.\n\nFrom my point of view, the most important environmental resources are clean air and clean water.  If you pollute those resources then nothing will live - people, animals, plants - we all need clean air and water.\n\nTrees help clean the air, which is why it is important to have forests and parks, so the trees can consume the carbon dioxide we breathe out while they breathe out the oxygen we breathe in.

Nuclear energy is not renewable, once the fuel is spent it can't be recharged (at least not easily).

Renewable energy resources may be used directly, or used to create other more convenient forms of energy. Examples of direct use are solar ovens, geothermal heating, and water- and windmills. Examples of indirect use which require energy harvesting are electricity generation through wind turbines or photovoltaic cells (PV cells), or production of fuels such as ethanol from biomass (see alcohol as a fuel). A parameter sometimes used in renewable energy is the tonne of oil equivalent (toe). This is equal to 10,000 Mcal or 41,868 MJ of energy.\n\nIn a sense, renewable energy may be categorised as free energy, although most renewable energy sources would not normally be called "free energy". In engineering, free energy means an energy source available directly from the greater environment and which cannot be expected to be depletable by humans. Renewable energy development is concerned with the use of renewable energy sources by humans. For aspects of renewable energy use in modern societies see Renewable energy development. Modern interest in renewable energy development is linked to concerns about exhaustion of fossil fuels and environmental, social and political risks of extensive use of fossil fuels and nuclear energy.

Yes wind is definitely a renewable energy source. Take a look at the link provided for more info on RES and other examples.

Coal is not animal. It is not vegetable. There is only one thing left. Mineral. Deduction. It works.

Hydroelectric: moving water from natural or artificial waterfalls powers turbines.\n\nSolar: Special reflective surfaces called photovoltaic convert the sun's radiation into energy, used to power turbines.\n\nWind:  Large turbines are pushed by the movement of the winds; resemble giant windmills.\n\nOil, Natural Gas & Coal (fossil fuels):  Are extracted and burned to power generator turbines.\n\nNuclear (fission): The power of the atom is harnessed as atoms are split apart and the resultant energy used to power turbines; buildings marked by iconic hour-glass-shaped cooling towers.\n\nBiomass: The buring of biologic materials to power turbines.\n\nWaste-to-Energy: the burning of waste materials (such as trash) to power turbines.\n\nNuclear (fussion): Still being developed; fusing atomic nuclei together and capturing the resultant release of energy.

Actually, these natural resources are being used to generate electricity. There are drawbacks to each of them, as there are drawbacks to using coal and nuclear energy. \n\nSome of the top drawbacks to these forms of energy are:\n1) consistency - most people want power day or not, whether the wind blows or not and whether the river is high or not. \n2) energy content - these forms of energy are not as efficient as burning fuel, typically\n3) cost \n4) specific concerns, such as birds getting caught in wind turbines, fish habitat being destroyed by hydroelectric dams, etc.\n\nPutting these all together, there are significant hurdles to overcome.

Yes. In about 150 years there will be no oil if we continue this way.\nAnyway .. there are unlimited resources, at least for energy, ... solar/eolian/waterfall energy.\nHope this helps

Yes natural gas is a type of fossil fuel.  Other examples of fossil fuel are oil and coal

probably you mean ELECTRICITY.\noil and petroleum could be used to produce electricity. There is such a thing as electrical energy.

Natural gas is a very good source for energy, but it is non-renewable with our current technology. \n\nHydro-electric is a viable energy source for electricty. It will always be available unless the water cycle ends.\n\nCoal is a good source for heat and power, but it does have some polluting characteristics in its natural state.\n\nNuclear is good for electricity production, steam generation and heat (from steam), it does leave residual waste, that is more concentrated radioactivity than what occurs naturally.\n\nFuel cells require power to produce but they work very well. They use readily available materials and can be scaled to the power output that is needed.\n\nGeothermal is good for heating houses and on a large scale in some areas for producing electricity. It is also a renewable power source.\n\nWind and solar are two more options that are becoming readily available for the end user. They are generally coupled with a battery system for calm periods of weather and night time.

All fossil fuels are formed by decayed plants and animals. Oil, gas, coal.

Oil is non-renewable.  So it will run out but NOBODY knows when.
