In light of rising energy demand, solar and wind power are popular renewable energy sources. A need for the hour is for reliable little wind power at a reasonable price. The materials needed the cost of continuance and function, and the cost of fuel influences the cost of energy production. Material costs are inversely related to energy costs. The blade design is critical in any wind turbine design. The choice of material is a critical element in blade design if the blade is to have a long predicted life. For smaller wind turbine blades, several materials such as wood, fiber glass, carbon fiber, natural fiber, and sandwiched composite items are provided. The main features to consider while choosing a blade material include hardness, toughness, density, price, and affordability. The materials for a wind turbine blade are indeed an essential part of the design process. These articles present numerous materials as potential blade options and use ANSYS computational modeling to select the best one.

In the industrial rebellion, the air pollution takes on the hike owing to fast growing use of fossil fuels. In developing countries like India, the automobile sector has developed as a key consumer of fuel and a key contributor to air pollution cause an increase in the greenhouse gases in the atmosphere results global warming leads to increased tailpipe emission and the consequent harm effects on public health. For the prevention of adulteration and monitoring of automobile fuel quality at the distribution point therefore, is highly important. Quantity and Quality of petrol is ensured, as it plays a major role in customer satisfaction. In addition, the petrol bunks require manual intervention for filling the petrol and collecting the cash. The unwanted fuel consumption by the public also leads to increase in cost of living. This paper aims to ensure the quantity and quality of petrol through duration of switching on the pump arrangement and voltage level of pH electrode. Concerning the benefit of the society based on the inflation, our government have to take necessary action to introduce petro cards which limits the per head fuel consumption according to the type of customer needs. In this paper for modelling purpose three different types of petro cards were designed based on the fuel need and essential needs of the public.
