What alternative source of energy do you think will be the most common in the future?

Personally I think that wind energy will become very common in a matter of years.

Wind energy certainly seems to be the alternative energy source that is receiving the most attention now.  But according to the Cleantech Group, citing a report from Melissa Schilling, a professor at New York University at Stern, geothermal energy "has surpassed wind as the most efficient alternative energy technology. In addition, geothermal technology is improving at the fastest rate, the report says."

Schilling's study included data from the U.S. Department of Energy’s National Renewable Energy Laboratory on the cost per kilowatt-hour at active power generation projects in 2005:

  • Geothermal, $0.031 to $0.08
  • Wind, $0.043 to $0.055 
  • Biomass, $0.066 to $0.08
  • Solar, $0.11 to $0.31
  • Hydroelectric, $0.006 
  • Coal $0.021
  • Nuclear, $0.022
While the study focuses on larger applications of geothermal energy, on a smaller scale, much like solar panels on roofs, home owners can make use of geothermal energy through the use of geothermal heat pumps, which make use of the ground temperature a few feet below the surface. It is certainly something that I will consider if I build a house in the right area.
