  Wow, we have people interested in such things. I was a bit skeptical regarding this, while talking to Ash a few days before. Looking forward to see the posts in this thread.
  Will be adding my own points later.

  I'm still trying to figure out how to convert solar energy into useful electrical energy to power street lights. Currently it's just too expensive.

  Wind farms- both offshore, on land as well as building mounted.
  solar towers- have a small land space footprint due to being vertical. votaic cells have a long way to go before they are truely viable.
  tidal/wave generation would also be a good idea to explore. they are currently testing units in the Hudson river.

  Why don't you open a thread on that on CE? We've had quite a number of discussions of solar energy here. At least the power requirements are set.

  I guess I should post few stats before we discuss this. Also, we should have someone who works in thie field (solar panel manufacturing) to give us better inputs.

  oceans contain the fossils + the shock waves produced in ocean can be used to create electrical energy in an environment friendly way(not tidal energy)
  
  guys we do say solar energy usage is best, but when the life of solar cells finishes after whatever amount of years, their disposal is difficult. :\

  OK guys here we go, Tapping the solar energy is the best, coz everything else is powered by sun and it's in plenty. To this day people have been focusing on Solar PV. The current day tech is super expensive plus pure silicon is not abundant. There are few tech that makes solar promising.
  Thin film Solar -> This is a PV tech, but uses different material. This will be future of solar PV ! This will be produced like clothes (as in textile) if everything goes well.
  The other most promising is the Solar thermal. The same tech used in solar water heater. It's as simple and works well for bigger plants.Focus the heat from SUN to heating element, heat the fluid, generate steam n them to steam turbines. There are many variations in the same, the most promising till now is the tech from Ausra (google it)

  ever hear about printed solar cells?? no?? take a look here :

  I see immense potential in ocean waves. It might be unscientific to say "endless" but indeed it is inexhaustible.
  
  The design that comes to my mind is a buoy floating on the surface of the ocean and connected to a dynamo by a shaft. As the waves move the bouy up and down, the dynamo rotates and generates electricity.
  
  The advantage is that it can be placed at any point on the ocean. independent of whether conditions. A tsunami is not included though.
