What are some hands-on learning activities for Renewable Energy education?

To make the most of your solar oven while cooking, it is essential to place the oven strategically in direct sunlight. It is also recommended to use cookware that has a dark color as it can absorb more sunlight and improve the cooking process. However, it's important to keep in mind that solar ovens generally take longer to cook than conventional methods. So, be patient and give it enough time to cook your food thoroughly.

For the efficiency of the harvested energy in the oven it is better to use good insulators to hold the heat by using simple and easy to find materials such as newspaper remnats or other type of paper waste materials

It's an eco-friendly device that uses reflective surfaces to concentrate sunlight onto a cooking chamber, converting it into heat for cooking food or sterilizing water. There are various designs including box cookers, parabolic cookers & panel cookers each suited to different cooking needs & temperatures typically ranging from 90°C to 200°C. While solar ovens are environmentally friendly, emitting no harmful emissions & reducing reliance on conventional fuel sources, their effectiveness is dependent on sunny weather conditions making them less practical in cloudy or inconsistent climates. They are particularly valuable in areas with limited access to traditional fuels.

For safety purpose on this mini projects it is better to put in place all the basic measures in place to avoid any electrocution or hazard once the energy is harvested, proper measurement tools (basically multimeters) to know the exact intensity and range of the produced power. and basic knowleadge of electricity (alternating or direct current) has to be shared before attempting this mini projects

It's a device that converts the kinetic energy of wind into electrical power. It primarily consists of blades, a rotor, a nacelle, a tower & a base. Wind turbines come in two main types: horizontal-axis, which are most common & resemble traditional windmills with the rotor shaft & generator at the top of the tower & vertical-axis, which have a vertically arranged rotor shaft, advantageous in areas with variable wind directions. Sizes range from small micro-turbines for individual use to large utility-scale turbines for wind farms. Used in areas with consistent & strong winds, such as coastal regions. Challenges include their dependency on wind availability, potential environmental & wildlife impacts & noise concerns for nearby areas.

You can also utilize digital tools for this purpose. There are free software, such as QBlade, which allows you to design a turbine and its blades, and conduct performance calculations. You can experiment with various parameter, design your own blade and turbine, then compare it with existing wind turbine performance. This activity should help you better understand how wind turbine characteristics impact its performance.

regardless of how small the project can be as long as it will generate any power, A well detailed introduction to the main parts of the system (water reservoir,water chanel head,turbine capacity, generator and as well load types ) and system sizing will be very helpfull so that at the end of the assembling it can be eassy to predict the parameters(Voltage,current,power) of the harvested power.

A hydroelectric generator is a key component in hydroelectric power plants, converting the kinetic of water into electrical energy. It works by channeling water typically from a river or reservoir to flow over a turbine, which spins & transforms the water's kinetic energy into mechanical energy. This spinning turbine is connected to a generator, where the rotation activates magnets to generate electricity. Hydroelectric power plants can be of various types, including impoundment (using dams & reservoirs), run-of-the-river (utilizing a portion of a river's flow) & pumped storage (storing energy by pumping water to higher elevations). Challenges such as environmental impacts on local ecosystems, high initial investments & water availability.

Biomass briquettes are eco-friendly solid fuels made from compressed organic waste materials like agricultural residues, wood chips & sawdust. This process involves drying the biomass to reduce moisture, then compressing it under high pressure to form uniform & efficient briquettes. They offer a sustainable alternative to traditional fossil fuels, exhibiting high combustion efficiency and producing less smoke, thereby reducing carbon emissions & contributing to waste management. Widely used in domestic & industrial heating, cooking & even in power generation. However, it faces challenges such as variability in quality the need for production equipment investment & sometimes the requirement for binding agents.

I remember when my lecturer came to the class with some biomass briquette. It would be interesting to make one for myself and use it.

An energy audit is a comprehensive process that evaluates energy usage in a building or facility to identify inefficiencies & opportunities for energy conservation & cost reduction. It involves assessing current energy consumption patterns, conducting a thorough site inspection of energy systems & using tools for measurement and data collection. The audit pinpoints areas of energy waste, such as outdated equipment or poor insulation, and leads to a detailed analysis of energy flows. The outcome includes a report with recommendations for improvements, such as equipment upgrades and insulation enhancements, along with a cost-benefit analysis to understand the financial implications and payback periods of these improvements.
