What kind of renewable energy is the cheapest to manufacture?

    The three dominant industries competing are solar energy, wind energy and hydro power, and they all have pros and cons.  China has proven to provide the cheapest solar energy: http://www.gstriatum.com/solarenergy/2010/02/china-may-be-worlds-cheapest-solar-energy-provider/.  Renewable Energy Certificates systems of funding are the most cost-effective incentives for renewable energy: see http://en.wikipedia.org/wiki/Photovoltaics.

    Interesting question. One way to think about energy is not “manufacturing” or “creating” it but rather tranforming or converting it into a form we can utilize. This usually means electiricity or heat. So, for example, trees convert the sun’s energy into cellulose, and then if we burn it in a wood stove or in a gassifier, we are converting the energy stored in bonds to heat or gases that can be used for other purposes (e.g. heating a house or running an engine).  Trees are pretty inexpensive to grow.
