What are the Sources of energy?
144961
There is only once source of energy: the Big Bang. Everything else is just energy accounting.

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.

solar energy to create heat and use that to turn turbines(as in a hydroelectric the force of water turns turbine), windmills use the wind to wind the huge fans and the mechanical energy to wind turbines to create electricity. states like california, new jersey and new york use these kinds of technology.

Energy that enters the system from the surroundings.

The ultimate source of energy in all. living systems is the sun

The best way is to build nuclear power plants. Duke Power of North Carolina has already built several. The modern world must have energy. There are several sources of energy of which coal and other fossil fuels is one. Nuclear is another.  There is also wind, solar, tides. Even gravitation--hydroelectric being an example.

not quite sure what you are asking but:\n\nfirst form of energy was human power (brute force)\nthen came fire (heat energy)\nwind power for flour mills\nsteam power\nelectricity (then the different forms of generating it, coal first, gasoline, nuclear, wind, solar etc)

Sugar, water, wind, sunlight.  Brazil is currently making fuel out of sugar for vehicles.  Iceland will be running all of their vehicles on hydrogen, in the next 20 years, and all of their energy sources are currently being harnessed on natural water sources such as thermo-heated water sources that drives massive turbines.  In Palm Springs, CA. they use wind farms to generate electricity.  And solar power could be harnessed cheaply by most nations on Earth to supply energy.

Dead.\n\nThe only source for energy for life on earth is the sun, and the only way that energy gets here is light.

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

Many forms of energy exist around us. Energy cannot be created or destroyed, only changed from one form to another. If a person ever says that energy is lost, what really happens is that energy is spent or changed into different forms. It never really is lost. For example, if you use water energy to create mechanical energy, you might "lose" some energy by creating heat energy in the form of friction.

Almost all power plants use some heat source (coal, natural gas, nuclear pile, geothermal heat, concentrated sun rays) to generate steam. The steam turns turbines. The turbines turn generators.\nGenerators generate electricity which is where electromagnetism comes in. A simple model is this: when you move a magnet around a wire you see a current induced in the wire. Now a generator moves a whole bunch of coils of wire around magnets (or moves magnets inside lots of coils of wire) and thus uses electromagnetism to generate electricity.

A good place to start will be to look at the following websites \n\nThermal Energy and States of Matter\nhttp://www.pschweigerphysics.com/thermenergy.html\n\nThermal Energy\nhttp://sol.sci.uop.edu/~jfalward/physics17/chapter6/chapter6.html\n\nThermodynamics and Thermal Physics guides\nhttp://physics.about.com/cs/thermodynamics/\n\nIf your doing a project you might look into "Ocean Thermal energy conservation" as a topic.\n\nOcean Thermal energy conservation is used to generate electricity using the temperature difference of seawater at different depths

Alternative forms of energy, some which can be used today. Solar, Wind, Water etc.

1. a car uses mechanical energy to be able to move\n2. a flat iron uses electrical energy to be able to heat up\n3. an oven use heat energy to cook food\n4. a lamp uses light energy\n5. a sonar uses sound energy to map the ocean floor\n6. a battery uses chemical energy to produce electricity\n7. a nuclear power plant uses nuclear energy to produce electricity

"The Sun has been producing solar energy, or heat, since about the same time the Earth was formed 4.6 billion years ago. Solar energy comes from deep within the core of the Sun. There, the temperature is about 27 million degrees Fahrenheit, and the pressure is about 340 billion times the Earth's pressure at sea level. This creates nuclear reactions that release heat energy through convection (http://www.solarviews.com/eng/edu/convect.htm). Five million tons of energy are released from the Sun's core every second. This is the energy that allows life on earth to exist! Scientists predict the Sun will last another five billion years before it collapses into a white dwarf, a star at the end of its burning stage."
