This report by Canaccord Adams provides an investment review of the major renewable energy technologies; geothermal, earth energy, hydro power, solar power, ocean power, biomass, wind power, and important spin-off technologies like energy storage.
These reviews contain summaries of the technologies, the investment opportunities, their economics, and their current power generation costs.
More generally, this paper outlines the characteristics that are likely to make a renewable energy technology successful. It also discusses some of the general factors that are likely to drive development of renewable energy such as energy security and renewable energy incentives.
Finally, this paper concludes with a review of life-cycle analysis of CO2 emissions, illustrating the relative greenhouse gas abatement that can be achieved by the technologies studied.
