1. Solar Energy
Solar energy is a form of energy which is widely available in abundance and have many different uses. Energy provided by sun in 1 hour is equivalent to energy consumed on earth in one whole year. And for this reason, there is ample opportunity to work and use this energy in comparison to any other form. Solar energy can be used to heat our homes, heat water, cook our food, power our lights etc
Example: During day time solar energy can be used to power the water pump and also charge the rechargeable batteries and use them to power garden lights in the night.
2. Wind energy
Wind is a form of solar energy and is a result of the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and the rotation of the earth. Wind flow patterns and speeds vary greatly across the United States and are modified by bodies of water, vegetation, and differences in terrain. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity. The terms wind energy describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.
Example : how do wind turbines make electricity?
Hydro (water) energy: As countries throughout the world search for renewable sources of energy, the answer may lie in the oceans that separate us. WATER POWER is a renewable source of energy that uses the power of falling water to turn turbines, which produce electricity. This type of energy is also known as hydro power. Turbine generators can harness energy from ocean surface currents that travel in relatively constant directions.
Example for harnessing water energy:
Biomass
Biomass is basically a stored source of solar energy initially collected by plants during the process of photosynthesis whereby carbon dioxide is captured and converted to plant materials mainly in the form of cellulose, hemi-cellulose and lignin. The term biomass therefore covers a range of organic materials recently produced from plants, and animals that feed on the plants. The biomass can be collected and converted into useful bioenergy. It includes crop residues, forest and wood process residues, animal wastes including human sewage, municipal solid waste, food processing wastes, purpose grown energy crops and short rotation forests
Eg : Dump any liquid waste to light up the street lights. This posturizes how our future energy needs have to be met.
Task:
Your job in this project is to understand/learn about the respective energy and how it works? Based on your understanding you have to make a model (Still/working) of your experiment and prepare a research report.
The research report should contain a) Introduction (purpose of your experiment), b) literature review, c) methodology/analysis (the materials and equipment you will need to do the experiment, how to assemble and conduct the experiment, what you may see during the experiment etc) d) conclusions, e) future prospective and f) references

Explanation / Answer
1)renewable sources benifits....., how to use renewable energy sources to acquire more energy?increase the usage of renewable resources ike solar enery,wind energy,hydroenergy and bioenergy.
2)plan to increase the production of mechanical enery(electricity etc..) by converting kinetic energy using renewable sources like solar,wind,hydro and bio energies.
3)by uisng these natural resources we can increase our production effectivly and naturally. we caan produce electricity using solar,wind,hydro and bio energies.
4)yes, i recommed this as an alternative energy form. (because we can produce mechanical energy by using any one of these)
MODEL
1))1.firstly by using the solar energy we can produce electricity to our homes,we can use it for cooking,and for many more we can store the sun energy in day time and use it whenever we need.
2.by identifing the wind flow we can use this wind power to generate electicity and for pumping water.
3. by using the abundant hydro energy we an generate by running turbine on hydro currents.
4. by using humain, animals, munical wastage and residual we can generate bioenergy which can generate mechanical energy.
2)by converting the renewable sources into mechanical energy there by generating electricity. eg: by wind energy we are converting kinetic energy in to electricity.
