Hybrid energy systems such solar and wind energy in combination with diesel generator can be applied successfully in areas where grid connection is not available or considered uneconomical. Their costs can be minimized through proper equipment sizing and load matching. This study represents the cost analysis of various models of hybrid systems for powering a remote area telecom tower located at...

a hybrid hydro/wind/photovoltaic base on hydrogen storage system is designed to supply power demand of pump stations. the aim of this design is minimization of net present cost of the hybrid system. optimization problem is subject to reliable supply of the demand. the system is investigated in the north west of iran (meshkinshahr) and the local data is applied. about 12 pump stations are found ...

In this study, the energy demand of a house in Gebze, Turkey, is met by using wind energy as a primary energy source combined with rechargeable batteries. The wind-battery system is simulated by MATLAB while considering that energy continuity is maintained by using a sufficient number of batteries. A life-cycle cost analysis is carried out over a 20-year system lifetime because the operating ti...

due to increasing expansion of energy consumption and also the decrease and tendency towardsending fossil energy reserves, the current energy cycle needs to use alternative energy speciallywind energy, because it’s considerably cheaper than other recycling sources. the presentresearch investigates suitable possibility of exploiting wind energy to create wind power stationin soltanieh zone of za...

Untapped pine needles with high potential for energy generation in the hilly area are not only a waste of resource but also increase the chance of environmental hazards as forest fires and GHG emission. This study is conducted to propose a new hybrid system (PV/Wind/Biomass) using abundant pine needle resource as a replacement of existing roof-mounted PV/wind hybrid system and analyse the feasi...

Wind power, as a renewable source of energy, reduces the greenhouse gas emissions. For Finland, the technology also brings business opportunities, as the Finnish industry already has a position in the global, fast growing wind power market. The wind energy project within the Climtech Programme focused on the technology export potential of Finnish industry in wind power markets, and on the reduc...

Wind energy is a fast-growing and promising renewable energy source. The investment costs of wind turbines have decreased over the years, making wind energy economically competitive to conventionally produced electricity. Size scaling in the form of a power law, experience curves and progress rates are used to estimate the cost development of ever-larger turbines. In life cycle assessment, scal...

The environmental impacts of fossil-fueled electricity drive interest in a cleaner electricity supply. Electricity from wind provides an alternative to conventional generation that could, in principle, be used to achieve deep reductions ð450%Þ in carbon dioxide emissions and fossil fuel use. Estimates of the average cost of generation—now roughly 4b=kWh—do not address costs arising from the spa...
