Electric Power Generation and Energy ConservationEnergy production and Energy saving
NEDO actively undertakes the development of new energy (e.g.,
photovoltaic, wind power, biomass and waste, geothermal power,
thermal utilization and full cells) and energy conservation
technologies, verification of technical results, and introduction and
dissemination of new technologies (e.g., support for introduction).
Through these efforts, NEDO promotes greater utilization of new
energy and improved energy conservation. NEDO also contributes to
a stable energy supply and the resolution of global environmental
problems by promoting the demonstration of new energy, energy
conservation and environmental technologies abroad based on
knowledge obtained from domestic projects.
