“…Studies have also been conducted to evaluate the potential for and effects of renewable energy development in Hong Kong. It is found that the carbon intensity for the renewable energy scenario will be reduced by 57% by 2020 [24,25]. Evaluating the province-level policies and actions is crucially important, but few studies test the effectiveness of different policies at China's province level.…”

Abstract:Wind energy has become a fast growing industry in China in the last decade. The development of the wind energy industry presents interesting policy questions. In the context of China, in additional to national energy policies, provincial policies were designed and implemented to stimulate the growth of wind power. This paper examines factors, especially provincial wind energy policies, in driving the growth of wind power capacity in the Chinese provinces. Statistical analysis with a longitudinal data set for wind power capacity in Chinese provinces from 2001 to 2012 reveals that the adoption of wind energy policies and a general energy plan at the provincial level are having positive effects on the growth of wind capacity in Chinese provinces.

“…This amount accounts for approximately 10.5% of the total wind electricity produced [14]. This problem also occurs in the PV industry because of power transmission capacity constraints; in some major PV power provinces, the idle power generation capacity of the PV power stations amounts to 13.78% [15]. Nonetheless, China's coal-based power structure cannot be modified in the short term; therefore, the large-scale promotion of EVs merely increases coal-fired power consumption.…”

In China, the power sector is currently the largest carbon emitter and the transportation sector is the fastest-growing carbon emitter. This paper proposes a model of solar-powered charging stations for electric vehicles to mitigate problems encountered in China's renewable energy utilization processes and to cope with the increasing power demand by electric vehicles for the near future. This study applies the proposed model to Shenzhen City to verify its technical and economic feasibility. Modeling results showed that the total net present value of a photovoltaic power charging station that meets the daily electricity demand of 4500 kWh is $3,579,236 and that the cost of energy of the combined energy system is $0.098/kWh. In addition, the photovoltaic powered electric vehicle model has pollutant reduction potentials of 99.8%, 99.7% and 100% for carbon dioxide, sulfur dioxide, and nitrogen oxides, respectively, compared with a traditional gasoline-fueled car. Sensitivity analysis results indicated that interest rate has a relatively strong influence on COE (Cost of Energy). An increase in the interest rate from 0% to 6% increases COE from $0.027/kWh to $0.097/kWh. This analysis also suggests that carbon pricing promotes renewable energy only when the price of carbon is above $20/t.

“…Power conditioning units, such as inverters, are also part of the supply system. Hybrid wind turbine and PV modules, offer greater reliability than any one of them alone because the energy supply does not depend entirely on any one source [31][32][33][34]. Figure 5 shows the schematic diagram representing the scheme as implemented in the HOMER simulation tool.…”

Abstract:Shortage of electric power is a serious problem in Ethiopia. The population living in urban and semi urban areas connected to the national grid makes only less than 20% of the total. The remaining 80% of the population in scattered rural villages and have very remote chance to get electricity from the grid. The only realistic approach to electrify the rural areas seems therefore to be the off grid system. Study was conducted to assess suitability of stand-alone wind-solar PV hybrid power for Debmel village which is detached off the main grid line. The data required for this work (wind speed and sunshine hours) were obtained from the National Meteorological Agency (NMA) and analyzed using HOMER & MATLAB software's. The actual data used was from Dire-Dawa station, which is the closest meteorological station to the village. Both wind power and solar PV power potentials were evaluated from wind speed and sunshine hours of the station, respectively. The electrical load for a model community is considered and a community school together with a health post is included. For the feasibility study of the hybrid system HOMOR is used. By running the software the optimization results have been generated and arranged according to their least net present cost. Furthermore, a sensitivity analysis also carried out for the major sensitivity components of the hybrid system (like PV price, hub height and diesel price). The study revealed that the area has abundant solar energy potential (6.12 KWh/m 2 /day) but its wind potential is not as promising. This is partly attributed to the level at which wind speed measurement was taken, 2 m, instead of the recommended 10 m height. The result of the software shows that the most cost effective system, i.e. the system with the lowest net present cost, is the PV-generator-battery-converter setup. For this set-up, the total net present cost (NPC) is $ 155,875, the cost of energy (COE) is 0.415$/kWh, contribution from renewable resources is 91%.
