The increasing world population and demand for fossil fuels for energy generation have defect the environment due to pollution and global warming. Therefore, it provoked the world to focus on renewable energy resources. Solar power and Biomass are among the good available renewable energy sources in most parts of the world. Combining both sources is a promising way to reduce greenhouse gas emissions and a reliable investment in energy. However, this type of energy has yet to be considered seriously in Iraq. This research uses theoretical and experimental studies to evaluate the energy production from hybrid energy sources (Biomass and solar) in Diyala province, Iraq. The practical part focused on creating a small-scale prototype to verify the success of Biomass in Iraq and then expand on a large scale. Moreover, the gas generated has a more economically viable and helpful heat source for cogeneration power plants. The expected electricity production from wasted food in Iraq is about 38.5 MWh. Finally, this study can be a good advantage in investigating the feasibility of operating a hybrid solar-biomass power plant in Iraq.

“…SPAPVs used for water pumping have several remarkable advantages: they reduce or eliminate dependence on electricity or diesel; they are environmentally friendly because they generate carbon-free electricity; the cost of operation and maintenance is lower, which minimizes the tendency to reduce investment [40]. Water pumping with systems powered by energy produced by PVs is used more and more for domestic water supply [41], for populations and animals in arid and semi-arid rural areas [42]. SPAPVs are effective solutions for irrigating isolated areas, with a convenient distribution of daily sunshine and global solar radiation [43].…”

Effectiveness of Measures to Reduce the Influence of Global Climate Change on Tomato Cultivation in Solariums—Case Study: Crișurilor Plain, Bihor, Romania

Tomatoes, one of the most appreciated vegetables consumed, are crops well adapted for cultivation in arid and semi-arid conditions, with the success of large yields guaranteed by covering water consumption through irrigation. Solar Pumps—SP are driven by Photovoltaic Panels—PV (SPAPV), eliminating the dependence on electricity or diesel; they are environmentally friendly because they generate carbon-free electricity, and the cost of operation and maintenance is lower. In order to preserve the water administered by drip to the tomato crop grown in solariums, mulching is used. In Husasău de Tinca, in the Crișurilor Plain, the cultivation of tomato varieties without mulching (WM) and with mulching with black foil (MBF) was studied. To answer the question “How effective are water conservation measures in terms of energy independence?”, two variants of SPAPVs, direct pumping (ADP) and storage tank (AST) were simulated. It is proposed to determine the water consumption of tomatoes (ETRo), using the temperatures inside the solarium. In 2016, the average temperatures during the vegetation period with insurance of over 20%, were observed. The specific investment (SI) is 214,795 Euro ha−1 in the case of ADP and respectively 202,990 Euro ha−1 in the case of ATS. The payback period (IPT) is between 2.68 years and 2.53 years for the ADP variant and between 1.63 years and 1.54 years for the ATS variant. The indications for water use and irrigation water use show that in the MBF variant, the water administered by localized irrigation is better utilized than in the WM variant. The novelty of this study is the evaluation of the effectiveness of measures to reduce the effects of global climate change on tomatoes grown in solariums, useful for forecasting and watering restrictions, water consumption is determined from the air temperature measured inside the solarium, with insurance of over 20%. Taking into account the working hypotheses, the distribution of irrigation water in the solarium, with the help of SPAPVs, for tomatoes grown in the MBF variant, and a drip irrigation arrangement with ATS, the energy independence of the farm is ensured, the yields obtained are economically efficient, and the irrigation water is used rationally.

Tomatoes, one of the most appreciated vegetables consumed, are crops well adapted for cultivation in arid and semi-arid conditions, the success of large yields is guaranteed by covering water consumption through irrigation. Solar Pumps - SP are driven by Photovoltaic Panels - PV (SPAPV), eliminating the dependence on electricity or diesel; they are environmentally friendly because they generate carbon-free electricity and the cost of operation and maintenance is lower. In order to preserve the water administered by drip to the tomato crop grown in solariums, mulching is used. In Husasău de Tinca, in the Crișurilor Plain, cultivation of tomato varieties without mulching (WM) and with mulching with black foil (MBF) were studied. To answer the question "How effective are water conservation measures in terms of energy independence?", two variants of SPAPVs, direct pumping (ADP) and storage tank (AST) were simulated. Considering the conditions in the solariums, tomato crops do not benefit from the contribution of precipitation, therefore it is proposed to determine the water consumption of tomatoes (ETRo), using the temperatures inside the solarium. In 2016, the average temperatures during the vegetation period were observed with an insurance of over 20 %, the irrigation norms were 6945.7 m3 ha-1, for the WM variant and 6594.0 m3 ha-1 for the MBF variant, respectively. Specific Investment (SI) is 214,795 Euro ha-1 in case of ADP and respectively 202,990 Euro ha-1 in case of ATS. The payback period (IPT) is between 2.68 years and 2.53 years for the ADP variant and between 1.63 years and 1.54 years for the ATS variant, respectively. The indications for water use and irrigation water use show that in the MBF variant the water administered by localized irrigation is better utilized than in the WM variant. In the conditions of Crișurilor Plain, the best solution for the distribution of water in solariums, with the help of SPAPVs is the mulching system of tomatoes grown in solariums (MBF) and the arrangement of the drip irrigation system with a water storage tank (ATS).
