Nine Challenges of Alternative Energy

In his just-released report, "Nine Challenges of Alternative Energy" Lawrence Berkeley staff scientist David Fridley assesses the obvious yet too often overlooked obstacles to the widespread deployment of alternative energies around the world. The report can be downloaded here. According to Fridley, these nine challenges are:
  • Scalability and Timing
  • Commercialization
  • Substitutability
  • Material Requirements
  • Intermittency
  • Energy Density
  • Water
  • The Law of Receding Horizons
  • Energy Returned on Energy Invested
