In just over a few years, investment companies, banks, and other financing institutions have caught on to the renewable energy fever. The proof of this pudding is the meteoric rise in share prices of renewable energy companies, clearly because of high expectations from investors. But are the movements in value of a renewable energy company unsustainable?

Some experts believe that the natural limitation of these Projects, will limit the growth of the sector. Take biofuels for instance. The absence of a stable supply of feedstock will affect its growth and development, thus constituting a very real investment risk.

There is still a lot to be seen and heard about renewable energy resources, but don't let the banks fool you. Technology will evolve at a faster rate, now that sustained interest is there. Its just a matter of time before disruptive improvements take place and provide better gains for renewable energy providers.
