suggest a form of energy that can replace electricity?

ain't none 'cept gas and diesel

Fire\n\nInvention? Or discovery? *shrugs* But I'm thinking most of all we need and use just wouldn't be around without this heating component. Just a thought.

Get some power generators.

Electricity is a form of energy.\n\nIt can be generated from other forms of energy, for example, chemical energy (burning fuel, or a battery), mechanical energy (a windmill), nuclear energy (atomic fission reaction like in a power plant).\n\nIn a battery electrical energy is converted from the  potential energy stored in chemicals which is released when they combine.\n\nIn a fuel cell, chemical energy is released in another type of chemical reaction.\n\nNuclear plants, windmills, hydroelectric dams or burning fuel in a generator turns a turbine or motor which moves a coil of wire through a magnetic field which produces energy.\n\nIn thermoelectric energy, heat is turned into electricity when two different metals are heated.

Solar energy is the best energy in my view .With the help of this solar energy we can use solar cookers,solar lamps,solar geasers\nsolar heaters, solar refregirators etc

I am willing to do something about it. I recycle things all the time and travel on public transport all the time. If you would like to find out more of ways to save energy around the home there are plenty of websities to help you.

If you are into electrochemistry you could make your own solar cell or a flat panel solar cell. A solar cell is a device for converting energy from the sun into electricity. This project is fairly easy and there are plenty of pics to show you exactly how its done. \n\nAlso read the first source listed first because it tells you things you need to know for the second experiment.

I dont understand your question.  How can things work without electricity?  Electricity is power.  And power is essential for any instrument to work.  Do you mean to ask about using alternative electricity?\n\nYeah you can put the fridge in snowpacked mountains which will make things inside cool.

Electricity is a form of energy that can be transmitted efficiently through copper wires because it is a good conductor. To transmit the same electricity through air, you will need very high voltage as air has a high resistance. Additionally, the efficiency will also be reduced as there may be arcing. High voltage is also dangerous.\n\nHowever, when we send a Radio Wave, it is also a form of energy. In the early days of Radio, there is a circuit that is popular with Radio enthusiasts called the Crystal Radio. The Crystal Radio does not need a battery to power it. It uses the Radio Signals itself. With some innovative design, one can tap into the Radio waves and convert that into electrical energy. This is a form of wireless electricity. However, the power level is very low.\n\nSo potentially, it is possible but there are probably many challenges ahead. Today, it is still not viable but we never can tell, technology has always done the impossible.\n\nFor very short range, electricity may be wirelessly  transmitted via induction (magnetic fields). Some pace makers are recharged via induction.

Try a regenerative turbine pump.

Any power source you can get your hands on, but be careful.

Anything the energy can be converted to use for.\n\nUsually it is light and heat though.

A self sufficient solar driven electric car. It will never need recharging. The source of power will come from the solar paint, braking system, tires and aerodynamic wind turbines under the car.\n\nAnd a optional magnetic drive engine!

Yes, just by using an electric motor which is based on both attraction and repulsion.  You would still need a good source of energy though to replace the energy that is provided by the combustion of the fuel.

Maybe this can help...all you have to do is a search in Yahoo or Google...\n\nhttp://www.think-energy.com/ThinkEnergy/11-14/activities/EnergyTrans.aspx\n\nTry searching for "energy" or "kinetic energy"

Tough question, however Solar and Wind are viable sources of energy where available.  BioMass and utilization of human waste are also viable sources of future energy.  There's some speculation about technology to harness the energy contained in Ocean Water (currents) though I am not an engineer and don't understand it at all.  Finally, eliminating wastefulness and extending the usefulness of exsiting fuel types will assure at least in the short term enough for all (this is particularly aimed at the USA as the largest consumer of existing fuels per capata in the World, the question is why)
