Solar panels convert sunlight into electricity through photovoltaic cells made of semiconductor materials. When sunlight hits the cells, electrons are released and flow as a current, which can be collected and used to power devices or stored in batteries. Solar energy is a clean and sustainable source of electricity with no emissions or pollution. This simple eco model made of paper can perfectly visualize this extraordinary invention.
The “Electronic Model of a Solar Panel” project aims to showcase the principles of how solar panels work and the benefits of using them. It consists of various electronic components. This project is environmentally friendly because solar panels use solar energy, which is a renewable and environmentally friendly source. Compared to traditional methods of energy production, such as coal or natural gas, solar panels do not emit harmful greenhouse gases or cause air pollution. This project can demonstrate how easy and effective it is to use renewable energy sources, such as solar energy. This project can contribute to environmental education and awareness because it enables people to understand how solar panels work and what benefits they bring to the environment. By promoting such projects, people can be encouraged to use renewable energy and minimize their negative impact on the environment.
A wind turbine producing energy to charge batteries works by harnessing the kinetic energy of the wind to rotate its blades, which in turn rotates a shaft connected to a generator. The generator converts the mechanical energy into electrical energy, which can be used to charge batteries. The wind turbine consists of several components, including the blades, rotor, shaft, generator, and controller. The blades are designed to capture the maximum amount of wind energy and convert it into rotational energy. The rotor connects the blades to the shaft, which rotates as the blades turn. The generator uses this rotational energy to produce electricity, which is then sent to a controller that manages the energy flow. Overall, a wind turbine producing energy to charge batteries is an efficient and sustainable way to generate electricity. By harnessing the power of the wind, it is possible to produce clean, renewable energy that can be stored in batteries and used to power homes, businesses, and communities.
This model shows house with solar panels on the roof. It consists of a porcelain house which is painted red and green, and on the roof it has solar panels made of plasticine. Solar energy is classified as renewable energy sources so if we have photovoltaic cells we will have energy in our house even if power station won’t work for some reasons. Like everything photovoltaics has pros and cons because we have lots of energy but only if the sun is shining although to a small extent. Except that we will be independent with the solar panels, we will contribute to environmental protection too.
This model is a model of a wind turbine made of paper. A wind turbine is a renewable energy technology that harnesses the power of wind to generate electricity. The rotating blades of a wind turbine capture the kinetic energy of the wind and convert it into clean, emissions-free electricity. Wind power is a sustainable alternative to fossil fuels, which contribute to air pollution, greenhouse gas emissions, and climate change.
In the picture you can see model of solar panel made of paper on the bottom and aluminium foil and plasticine on the top. Solar panels are used to power lots of things from small garden or traffic lights to houses and even huge factories. This renewable energy source is affordable and every person who has enough space can have it on their estate to have their “own” power. Thanks this solution we can pay less for the electric current because we are our own supplier. We can install external power bank too, so that store excess of energy we produce. Photovoltaic becomes more popular nowadays because we should draw from renewable energy sources.

The mock-up consists of the inhabitants, we have a good demonstration of what they do, a block of flats, various activities, and a wind turbine. The wind turbine produces the electricity that the town needs in an environmentally friendly way. Instead of cars, we can see here the use of animals such as horses for lighter work, which is also a good and “healthy” idea. The residents spend time together in nature. And the solutions used here help to protect it, the ecosystem, but also the health of the community. This model shows what our life could look like in an ecological environment.
Model shown in the picture illustrates a wind turbine, device that converts the kinetic energy of the wind into electrical energy. It consists of a tall tower, a rotor assembly, and a nacelle, which houses the generator and other components. The tower supports the rotor assembly, which is made up of three blades that are connected to a hub. The blades are designed to capture the energy of the wind and turn the rotor, which in turn rotates the generator housed in the nacelle. The generator converts the mechanical energy from the rotor into electrical energy, which is sent through a cable down the tower and into the power grid. Wind energy is a clean and renewable source of energy that can help reduce our reliance on fossil fuels and mitigate the effects of climate change. Wind turbines are becoming an increasingly important source of electricity around the world, with thousands of wind turbines installed in countries such as the United States, China and Germany.
In recent years, the helicopter industry has made strides towards reducing its environmental impact by introducing innovative technologies and systems. One such system is the use of lighter weight materials, such as composites, which reduces the weight of the helicopter, leading to lower fuel consumption and reduced greenhouse gas emissions. In addition, modern helicopters are equipped with more efficient engines and control systems that allow for a more precise and economical use of the aircraft, further reducing its environmental impact. Manufacturers are also introducing recycling and waste management systems to reduce environmental impact during production and use. For example, Airbus Helicopters has implemented a “zero-waste-to-landfill” policy in its production facilities, which aims to reduce the amount of waste sent to landfill to zero. They also use a closed-loop recycling system for aluminum, which involves recycling scraps and chips generated during production. These initiatives help to reduce the environmental impact of helicopter production. Overall, these changes are making the helicopter industry more eco-friendly and sustainable, and have the potential to further reduce environmental impact in the future.
Modern airplanes certainly have a positive impact on the environment thanks to the use of innovative technologies and materials, such as hydrogen fuel which is a very clean source of energy that produces only pure water and water vapor when burned. As a result, airplanes powered by hydrogen fuel emit significantly fewer greenhouse gases than traditional airplanes. In the future, when hydrogen fuel becomes more common, it will have a huge impact on reducing greenhouse gas emissions in the aviation sector. Modern airplanes also utilize many other technologies that reduce their impact on the natural environment. For example, the use of lighter weight structural materials, such as composites, reduces the weight of the airplane, which means less fuel consumption. In addition, the use of more efficient engines and navigation systems allows for a reduction in fuel consumption and greenhouse gas emissions. All of these innovations and technologies make aviation increasingly environmentally friendly. Of course, there is still a lot of work to be done to reduce the impact of aviation on the natural environment, but developing and implementing innovative solutions is a step in the right direction.
The pumped storage power plant uses two water tanks, one higher than the other. When there is an excess of electricity, the pumps in the power plant pump water from the lower reservoir to the higher one. When energy is needed, water flows from the upper reservoir back to the lower one through the turbine, which generates electricity. Pumped storage is an efficient way to store energy because water can be pumped and stored until energy is needed. This simple model made of used materials can perfectly visualize and show how this natural power plant work.
The model of wind turbine generator. It uses wind energy to generate electricity. Our model is made of Lego bricks and includes a rotor with three blades, a generator, a gearbox and a tower. The blades are designed to capture wind energy and spin the rotor. Rotor is connected to the gearbox, which increases the rotational speed of the rotor and transfers the energy to the generator. The generator then converts the rotational energy into electricity. The tower is an important part of a wind turbine as it supports the rotor and blades. The tower’s height is essential because the higher the turbine, the more wind it can capture. Wind turbines are a renewable source of energy and can help reduce the amount of greenhouse gases emitted by traditional power plants. They are becoming more and more popular around the world as more and more countries work to switch to renewable energy sources. The LEGO wind turbine model is a great way to learn about the technology behind wind turbines and renewable energy. It is an engaging way to teach children about engineering and sustainability that can inspire them to pursue careers in STEM fields.

The model shows a solar panel, this device converts sunlight into electricity. It can be used to power household appliances or be connected to the mains. They are a clean and renewable source of energy and are becoming more and more popular as technology becomes more efficient and affordable. Solar cells are made of a semiconductor material such as silicon and are designed to capture the sun’s energy and convert it into energy. The solar panel itself usually consists of a glass layer that protects the solar cells from the damaging effects of the weather, and a metal layer that helps to conduct the generated electricity. We see that it is also connected to a device called an “inverter”. It converts DC (direct current) electricity generated by the panel into AC (alternating current) electricity.
Solar power is an environmentally friendly source of electricity with zero emissions or contamination. Photovoltaic cells composed of semiconductor materials are used by solar panels to transform sunlight into electricity. Once the cells absorb sunlight, electrons are discharged and create an electrical current that can be gathered and utilized to energize appliances or kept in batteries. Here we can see and example of complex charging system which contains solar panel and USB charge port.
