The one that I would be most interested in using is geothermal energy. There are some really exciting new applications of geothermal energy for use in heating and cooling homes that essentially involve putting a heat pump deep enough underground that it reaches the soil zone where the temperature is constant year round. This results in having a source of heat in winter and a heat sink for cooling in summer. Every house should have one!!!\n\nSadly the new energy plan proposed by the administration cut geothermal energy research to ZERO.

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.

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.

Wind mills and /or solar

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

The easiest thing would be to switch all cars to hybrid.  Right now.  The technology is here.  Wind power now costs less than coal, but our government keeps giving money to the coal industry because of lobbyists.

Fossil fuels, such as oil, natural gas, or coal, are non-renoewable sources of energy since the supply of them on Earth is pretty much fixed.

Solar power both thermal and photovoltaic, hydroelectric and hydromechanical, wind electric generators and wind mill mechanical drives. Alternative fuels; Methane, methanol, ethanol,Hydrogen.\n\nYou can pick up a photovoltaic cell at radio shack cheap.

It all depends on the area where you live. Like people in Florida would benefit most from Solar energy. People living near dams would benefit more form water energy. Wind energy would benefit people who live in the mountains. It all has to do with the geography of the land. But dealing with fuel options... I'm stumped!

Most likely Energy in Joules. We need a context though.

Thereare tons look under tidal turbines. Here is a site that should help you out. http://www.freeenergynews.com/Directory/Tidal/index.html

Alternate energy sources are our next step to stabilize our economy and lessen the dependence on other countries to provide us that need. However, they are extremely costly and hard to come by. Wind mills are a disaster in terms of the amount of space it needs to operate. Solar panels are not effecient everywhere, say Seattle or Alaska. Nuclear fission is the next step but since it is potentially dangerous as nuclear bombs, it's being closely monitored thus dampening the research process. I guess we are still depended on oil is because it is so universal and exremely easy to use and harness everywhere. I agree with you, if I had enough money to fund researches like these, I'd do it in a heartbeat!

Fossil fuel is the primary alternative due to price.  As the price of fossil fuel rises, a number of alternatives become more attractive.  Wind energy is an option, but it is not likely to be the main alternative.  Nuclear has a long history for power plants, but very limited short term potential for other applications.  Solar holds tremendous potential.  Gas to liquid technology and coal to liquid technologies are the most likely alternatives in the 5 to 10 year range.  Hybrid cars will help for a while, and in 15 years hydrogen fuel cell cars will start to have a MAJOR impact.

Wind energy is actually growing at a double digit rate, albeit from a very small percentage of the energy total.  Like solar and geothermal it's about as green as energy can get, so it is very responsible in that sense.   It will take strong government committment to spur it's use because it's still rarely competitive with fossil-based energy.   The Wall Street Journal had an article last week about the difficulty of the boldest experiment yet - a Danish island that has tried with limited success to get off shore wind energy as the primary source (it was going OK until the government withdrew subsidies).

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

It is renewable since warmth from the sun generates new wind all the time.\n\nThis is the opposite of oil.  Oil takes so long to produce that we use it up much faster than it is created in the earth.  We can actually use up all the oil.

The problem is oil is running out. Once the oil runs out, we will probably be able to switch to renewables and get by. But the problem is there are many things other than car transport we use petrochemicals for. Plastics, fetilizer, lubricants, moving tankers across the seas and so forth. We will still need those things, and wind farms will not fertilize our crops.\n\nSo the short answer is, we need to stop using oil for things we have alternative sources of power for, because we will still need oil for other things 100 or 200 or 500 years from now. For those things for which there is no replacement for oil.
