Abstract
In recent years, the prospective use of algae as an alternate fuel source for petroleum-based fuels has increased drastically. It has been researched extensively and proven that it can be used as a sustainable feedstock for producing green energy considering environmental safety. This article focused on the economically viable algal feedstock for the production of lipid content for its use as a feedstock for biodiesel production. For this purpose, the algal species Scenedesmus obliquus and Chlorella vulgaris were selected, and it was grown under lab and open ambient conditions with two Blue green Medium (BG-11) and Bold Basal medium (BBM). Upon the yield, it was noticed that the BG-11 medium gave optimum lipid yield for both species. Hence, it was determined that through this medium higher lipid yield can be expected, and based on the GC-MS result it was notified that it can be a viable source of alternate fuel.

Abstract
This study focuses on the conversion of chicken fat into chicken fat methyl ester (CFME) and its use in the diesel engine. Baseline fuel i.e., diesel and chicken fat biodiesel are the fuels tested to study their effect on the performance and emission characteristics of diesel engines. To enhance the performance and emission characteristics, ethanol up to 20% is added as an additive to the chicken fat biodiesel. The physiochemical properties revealed that the fuel blends properties are closer to the diesel fuel. The experimental investigations revealed that additive blended biodiesel enhanced the performance by reducing the brake-specific fuel consumption and increasing the brake thermal efficiency. Moreover, the emissions are considerably reduced by the additive blended chicken fat biodiesel. Therefore, chicken fat biodiesel can be considered as a substitute fuel to be used in the diesel engine without any modifications.

Abstract
The data on performance parameters of a horizontal axis small wind turbine (HAWT) with blade tip power system (BTPS) using permanent magnetic generator is presented. The tests are carried out for low wind velocities ranging from 7 m/s to 10 m/s. The data is acquired using data acquisition system equipped with Labview© software and the processed data is represented in terms of non-dimensional parameters, namely power coefficient (Cp), torque coefficient (CT) and tip speed ratio (λ). Moreover, as permanent magnetic generator is used in this HAWT with BTPS, the frictional as well as other losses are significantly reduced. This is reflected in terms of non-dimensional electrical power coefficient. The mechanical and electrical power coefficient values are closer with respect to each other. This measured data at laboratory conditions provides a benchmark for future open field environment tests and numerical simulation studies of this small wind turbine.

Abstract
This dataset disclose the investigational data on the extraction of bio-oil from seeds of Vitis vinifera through combination of mechanical pressing and soxhlet solvent extractor. Biodiesel is produced through single stage base catalysed transesterification process due to lower free fatty acid content in the Vitis vinifera bio-oil. Independent variable process parameters like molar ratio, reaction time and catalyst concentration are optimized using Artificial Neural Network, Response Surface Methodology and Adaptive Neuro-Fuzzy Interference System to predict the maximum biodiesel yield and the results are compared with the experimental data. Response Surface Methodology predicted a maximum Vitis vinifera biodiesel yield of 97.62% at methanol to oil molar ratio 0.2758 v/v, catalyst concentration 1.045 gm of NaOH and reaction duration of 1.11 hrs which is also confirmed with experimental results.

Abstract
The performance and load test data of the proposed H-rotor with semi-elliptical shaped blade vertical axis wind turbine is carried out at the laboratory using 1 m diameter axial fan. India has a long coastline and low-wind velocity ranging from 3 to 10 m/s which is available everywhere in the country irrespective of climatic conditions. The data article is carried out at different aspect ratios along with tilt of the blades and without tilting of the blades. These data sets provide the researchers to further study experimentally as well as numerically in order to enhance the performance of the proposed VAWT. The data presented here are measured at wind velocity ranging from 3 to 6 m/s. The raw data captured using data acquisition system are processed and presented in a form so as to compare it with other typical VAWT.

Abstract
This data article presents the experimental values pertaining to the bio-oil extraction, optimizing biodiesel production and formulation of emulsified fuel blends of E.tereticornisis bio-oil for its use in compression ignition engine. The E.tereticornisis leaves were collected from the interior region of Puducherry, India. Soxhlet extraction process, in the presence of n-hexane, yielded 5.2% of bio-oil. Based on the free fatty acid content, base catalysed transesterification process was adopted along with use of sodium hydroxide and methanol. Optimization of biodiesel yield was carried out by varying the operating parameters. A biodiesel yield of 74.19% was obtained at eighty minutes reaction duration, 1.8 l/g ms of sodium hydroxide, 70 °C reaction temperature and 8:1 oil to molar ratio. Furthermore, the physiochemical properties improved by emulsifying the obtained biodiesel with 5% of water in presence of surfactant through experiments carried out based on Taguchi׳s DOE method.
