† Fuji Electric Co., Ltd. opment Organization (NEDO) for a period of 5 years beginning in 2003, and has amassed a proven track record for developing and evaluating “microgrid control technology” that balances the supply and demand of energy within a regional grid consisting primarily of renewable energy sources such as solar power, wind power and biomass power. Combining its accumulated advance...

The Ukrainian renewable energy sector has demonstrated a significant increase in its power capacity, especially for solar and wind plants. Decommissioning the end-of-life equipment Ukraine not yet taken place, but it is only matter of time. With this mind, paper assesses quantities market values materials that could potentially be recovered from used plants, estimates impact their decommissioni...

Multijunction Solar Cells To achieve sustainable development goals, the use of high-efficiency III-V//Si multi-junction solar cells is attracting attention for transport equipment such as electric vehicles and unmanned aerial vehicles. The issue that needs to be addressed expand reduce their production cost. In article number 2200198, Yasushi Shoji co-workers, propose a cost-reduction technology.

The Department of Energy has outlined the SunShot initiative, a plan to increase the adoption of solar energy by making it more cost competitive without requiring subsidies. A key component of this plan is to reduce costs associated with the balance of systems (BoS), which accounts for more than 40 percent of the total installed cost of solar energy systems. Balance of Systems encompasses the r...

BACKGROUND AND OBJECTIVES Hemodialysis resource use-especially water and power, smarter processing and reuse of postdialysis waste, and improved ecosensitive building design, insulation, and space use-all need much closer attention. Regarding power, as supply diminishes and costs rise, alternative power augmentation for dialysis services becomes attractive. The first 12 months of a solar-assist...

passive solar systems such as solar chimneys need solar radiation in order to work. therefore, they cannot present stable natural ventilation when solar energy vanishes: to have a more robust and stable condition, solar energy should be stored during the day and released back during the night. phase change materials can save additional thermal energy during the day and release it during the nig...

Since the energy consumption has become one of the crisis of modern buildings, modeling the Iranian past architecture patterns could be helpful. The shopping streets as one of the main sectors consuming energy locate near the open spaces it seems, therefore, they need more thermal comfort. However, using passive techniques, the Iranian traditional bazaars architecture solved the problems regard...

in the present work, a prototype of a new type of solar collectors, which called direct absorption solar collector, was built and its thermal performance is experimentally compared with conventional flat plate solar collector under transient and steady state conditions. different volume fractions of multi wall carbon nanotubes in water and ethylene glycol mixture (70%:30% in volume) were used a...
