The world’s major stock markets and clean energy indices were mostly down this week as Americans headed into the Memorial Day long weekend. The only exception was the EnergyBoom Biofuel Subindex (E•B Biofuel) which increased 1% for the week.

The two top performing companies in the EnergyBoom Clean 100 Index (E•B Clean 100) last week were Capstone Turbine Corporation (NASDAQ: CPST) (+21.2 percent) and FuelCell Energy, Inc. (NASDAQ: FCEL) (+18.8 percent).

Capstone and FuelCell each provides distributed (off-the-grid) power generation systems they claim are cleaner and more efficient than the most commonly used off-the-grid systems powered by diesel engines.
