Energy
Development &
Power Generation
Technologies: mainstream:
solar (photovoltaic, concentrating, thermal), wind, water, biomass,
waste, hydro (large, small), ocean power (wave and tidal).
Low Impact
Hydropower - Hydroelectric facilities that meet certain criteria
(impact on river flows, water quality, fish passage and protection,
watershed protection, threatened and endangered species protection,
cultural resource protection, and recreation) to minimize their
effects on rivers, fish, and wildlife under a voluntary certification
program developed by the Low Impact Hydropower Institute (LIHI)

Renewable Energy
Technologies:
-
Biomass Energy
-
Biofuels: ethanol, made primarily from the starch
in corn grain; biodiesel, made primarily from soybean oil.
-
Geothermal Energy (geothermal or ground-source heat
pump, GHP)
-
Hydrogen
-
Hydropower
-
Ocean Energy
-
Solar Energy
-
Wind Energy
Ocean Energy
Technologies: Ocean
Thermal Energy Conversion (OTEC), Tidal Power, Wave Power.
Subcategories:
-
Point Absorbers/bobbing motion of the waves to
power a pump that creates electricity
-
Attenuators/heave-surge devices that use hoses
connected to floats that ride the waves.
-
Overtopping devices/seagoing vessels/floating
platforms capture the energy of offshore waves by funneling waves
through internal turbines
-
Onshore Systems extract the energy in breaking
waves

Hydrogen
Technology: Hydrogen
as an important energy carrier/storage buffer (current nascent
markets: continuous duty fork lifts, baggage carriers at airports,
back-up power for remote cellular tower sites).
Reforming
- separation of hydrogen from hydrocarbons through the application of
heat. Currently, most hydrogen is made this way from natural gas.
Electrolysis
- separation of hydrogen from water through the application of
electrical current.
Currently, hydrogen has
great potential as a power
source for fuel
cells.
