Solar Power harnesses the energy of the sun to turn water into high pressure steam. The sun gives panels which heat the water kinetic energy to affect the interaction energy of the water (like how you get a sunburn). The steam rotates a turbine to generate power.

Solar energy is used for two types of devices: thermal, and photovoltaic.  For your water heater, you are talking thermal.  Put tubing into a black box with a clear cover, put the box in sunlight, and you have a solar water heater -- details vary, but they don't matter much.  Photovoltaic use silicon cells (usually called solar cells, or solar panels) to generate electricity.  Solar-cell powered garden lights, where the light is a light-emitting diode, are becoming popular and inexpensive.  The solar cells charge a nickel-cadmium battery during the day, and the battery powers the lamp at night.

conventional means mainstream or those that most people use\nSo in general, fossil fuel - oil, gas, coal is what most of the world uses today.\nNonconventional could include solar, wind and even more exotic sources like ocean waves.  Another example is thermal energy such as what Iceland has done - also check out their new plans to totally avoid fossil fuel by going to fuel cell.

All of this are plus gas,petrol and nuclear energy. Water, wind and sun are called renewable energy resources.

Solar energy is horribly inefficient, it only converts appx 3-4% of the energy available it, it costs a fortune to. i would suggest using a different form of renewable source. use solar energy to heat you water (very simple non-electrical system - black hose-piping within a black box - supprisingly effective for what you may thtink it is, this also saves money on electricity. \n\nYou could convert your central heating to a heat engine system (loads of info online about it) - expensive outlay but unlike solar cells very efficient with it.\n\nother than that common household electrical requirements nowadays are sickening and really need the national grid juice to power it. If you have a river/stream by your house tha can easily be harnessed to power all your lights, refridgerator and basic amenities ... - however how many ppl actually have a stream... LUCKY BAS***D'S!\n\nGood luck with What ever you do, any one cutting down their fuel useage is good!!!

By capturing the light and storing it.\nFor example capturing the sunlight inside the glass chambers filled with special metal foils that will get heated and then can be used later in solar energy.\nSo, that we can use that energy to heat, light, cook, and many other things.

Fossil fuel power plants can emit many harmful pollutants, ranging from Nitrogen Oxides and particulates to heavy metals & mercury.\n\nThe radiation from the sun's nuclear fusion is what gives us solar energy, but it can also cause skin cancer.\n\nUse of solar energy generally requires using materials that have caused pollution as a byprodouct of their manufacture.

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

energy from the cosmos.\nall energy eminated from that first creation\nthe "in the beginning" creation or for moderns the "big bang "energy.\nIt is the energy still eminating from our cosmos

in Solar Battery!!\n\nmuahahahahahahaha

Each solar panel produces 60w of power. You'd have to look at your bill and see how many kwh you use and divide that by 60w/hr. By the way, prices have gone down. Solar panels cost about $300 now. And if you get enough and produce more power than you use, you can sell that to some electric companies.\n\nAs far as oil, do that for the whole world and see, remember though, the solar energy is always there, going to waste if we don't use it we lose it.

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

Typically a solar panel would be used to charge a 12 volt battery in circumstances where 110volt is not available.  12 volt power can be used for a lot of different things.
