Making enough money for business expansion isn't easy for many public renewable-energy companies. That's why so many are selling shares to or borrowing money from institutional investors.
Evergreen Solar (NSDQ: ESLR), for example, said it plans to raise $325 million by selling senior convertible notes. The solar-panel maker, based in Marlboro, Mass., would use the proceeds to complete a manufacturing plant in Devens, Mass., and to start construction of a plant to produce heat-resistant strings for making wafers that require less silicon than conventional ones.
Medis Technologies (NSDQ: MDTL), on the other hand, has raised $29 million by selling shares to institutional investors. Medis, based in New York City, develops portable fuel cells and other products through its subsidiaries, More Energy and Cell Kinetics.
The process of getting a technology from the lab to the marketplace is expensive, especially in young technology sectors such as fuel cells. Many ethanol companies also are having trouble getting enough money or regulatory approval to build plants (see Mascoma to Play Smaller Role in Pilot Project).
Here is a look at other companies that have gotten money or are looking for some:
