Renewable is not only the need of the hour, but also the talk of the town. And Engineering students are opting for the green when it comes to their B.E./B.Tech project. So, we thought of compiling ia list of project ideas based on Renewable energy. Students belonging to third year or final year can use these projects as mini-projects as well as mega-projects.
This list has been complied after referring to the project ideas that have come across the forum since last few years and searching across the web.

If you have questions regarding these projects feel free to ask them in the replies below. You may also ask for abstract of a project idea that you have or want to work on.

Here are the details about some -
1. Tornado-based Power Plant : If the energy of a tornado could somehow be sustained and harnessed, it could be used as an effective renewable source of energy. Something on the lines of what is being worked out in this project: Atmospheric Vortex Engine
2. Using Kites For Energy : Saul Griffith unveils the invention that his new company Makani Power has been working on: giant kite turbines that create surprising amounts of clean, renewable energy. Check -

3. Solar Satellites have the advantage of being above the weather conditions, and would be able to harvest electricity from the sun 24 hours per day. Below is a TED presentation about the technology by one of the first companies looking at this technology, Space Energy Inc. -

4. Inflatable Solar Collectors
Solar cells, mirrors, and rigging equipment are expensive and reduce the value of solar technology as a viable alternative energy solution. Below is a video of the Video of Cool Earth’s technology that solves these problems.
@Ankita Katdare • 23 Aug, 2012 • 1 like Solar Powered Mobile Charger -
With power-hungry smartphones becoming a norm, solar-cell based phone chargers are getting more popular but many are still often a little pricey. To build one of your own, you need -
Solar Cell, Project Box, 12VDC Car Power Outlet Socket and an adhesive of choice.
Instructables here has a step-by-step guide for you :
But you can always find better ways of developing things. So, find new ideas. 😀

Solar Powered Refrigerator -
You can build it in one of the following four ways:
1. Solar Cells Only.
2. Thermoelectric solid-state refrigerator powered by solar photovoltaic electricity - Using the Peltier effect to create a heat flux between the junction of two different types of materials.
3. Absorption refrigerator in which the boiler heat is generated from concentrated sunlight.
4. Stirling engine refrigerator in which the compressor is mechanically driven by a Stirling engine - When we heat gas using sun light, gas would expand and push the piston forward. We can use this method to power compressor of refrigerator.
@Ankita Katdare • 23 Aug, 2012 An Advanced Geothermal System -

This is the kind of energy that is discussed more often than implemented. And no one questions its potential. The scientists do not hesitate to say that if harnessed properly, it could be the single most effective solution to the world’s energy needs.
But very few know that the Web-Giant Google is also busy in privately funding its research and development. They are working on it for years now. Their system works by drilling a well several kilometers deep into the earth’s crust. Water is then injected into the well where it fractures the deep rocks, creating pockets from which steam is generated as additional water is pumped into the well.

The steam is then extracted through pipes where it turns turbines to create electricity. The water is then recycled back into the well where it is reheated and reused. The video below provides additional details on this exciting new technology.

The company calls it EGS or Enhanced Geothermal System:

@Swapnil Suman • 02 Jun, 2015 Renewable Energy Storage Methods | Energy Storage Requirements

Storing the Energy is an essential requirement for all facets of our life and it has been recognized as a basic human need. It is the key to accelerating economic growth, generation of employment, elimination of poverty and growth of human development especially in rural areas. In contrast to fossil fuel and nuclear-fuel based energy, the initial input power of a renewable energy source is outside our control. The use of renewable energy supplies constitutes a diversion of a continuing natural flow of energy; there are problems in matching supply and demand In a given time domain, i.e., matching the rate at which energy is used. The mismatch varies with time on scales of months {e.g.. house heating in temperate climates}, days (e.g., artificial lighting) and even seconds (e.g., starting motors).

The means of storing energy in a readily recoverable form when the supply exceeds the demand for use at other times is known as energy storage. Storage of primary fuels (e.g., coal, oil and gas) is also a form of energy storage, but the term ‘energy storage’ generally applies to secondary energy rather than to primary energy.

The performance of various energy-storage mechanisms can be measured and compared in (i) MJS (ii) MJm3 (iii) MJKg -1. The first is a very important and deciding factor but is difficult to estimate. The second is important where space is a prime consideration (e.g., indoor applications). The third is considered when weight is vital (e.g., in aircrafts).


1. The effective utilization of intermittent and variable energy sources such as sunlight, wind, etc. often requires energy storage

2. In some circumstances, electrical energy may be generated ether on land or at sea, at a location that is too distant from a consumption centre for conventional transmission lines to be used for example Ocean Thermal Energy Conversion. Means must then be found for both storing the energy and transporting it economically to a load centre.

3. Electrically propelled vehicles, which are expected to come into increasing use, also require some form of energy storage. Since the vehicle must carry its energy supply, the storage system must be readily transportable.

4. Energy storage is also required for ‘Load levelling’ in an electric utility to reduce the overall cost of generating electrical power. More efficient plants may be operated continuously at a rated power level, and the excess power during off-peak period is stored for use when the demand exceeds the base load. Thus, the use of less efficient units to meet the additional demand for power during peak load periods is eliminated.


Energy can be stored in various forms and the storage methods are classified on the basis of the form in which it is stored. Some of the important energy storage methods are the following:

1. Mechanical energy storage

(a) Pumped storage

(b) Compressed air storage

(c) Flywheel storage


2. Chemical energy storage

(a) Batteries storage

(b) Hydrogen storage

(c) Reversible chemical reactions storage

3. Electromagnetic energy storage


4. Electrostatic energy storage

5. Thermal (heat) energy storage

(a) Sensible heat storage

(b) Latent heat storage

6. Biological storage

I was just trying to imagine the project or trying to have a vision of your project but is it feasible??? Guys please know the difference between "a scientist and an engineer". As an engineer we have the vision within cost optimized value of project. well no doubt its very innovative. think about floating type solar PV cell having a good insolation power in your locality having reservoir or ponds( just for a say).

@Ankita , I feel that these projects should include those for storing solar energy as heat of fusion of inorganic salts alike Sodium Nitrate or mixture of nitrates. These are useful for cooking in individual houses.

@Ankita Katdare • 14 Jul, 2018

@Ramani sir, this research paper can be of use -

Inorganic Salt Hydrate for Thermal Energy Storage -


Salt hydrates are worthy of exploring due to their high-energy storage density, rational price, multiple sources and relatively good thermal conductivity.

This paper reviews the present state of salt hydrates targeting classification, properties, defects, possible solutions as well as their idiographic features which are suitable for applications.

@Ramani Aswath • 14 Jul, 2018 • 1 like

I agree. There are some issues though.

We did some work on this in the early seventies. Dropped as it proved too costly at that time. 

Worth revisiting. The problem is that high temperature solar collection needs some form of concentration, which implies a tracking mechanism to orient the concentrator to the sun as also arrangements to store the molten salts.

Well in solar you can use the solar-powered LED street light, auto irrigation and solar energy-based water purification system and something related to battery chargers.

I don't know much about geothermal energy though but try going through this document :<iframe src=";embedded=true" frameborder="0" allowTransparency="true" style="border:none;overflow:hidden;width:600px;height:600px;"></iframe>

@doreen I can help you with ocean/marine energy technology.

You can make a project based on solar+marine energy generation. Let me tell you some facts; More than 70% of the solar radiation reaching Earth falls on the ocean, heating the upper layers of the seas. This thermal energy, combined with wind and the forces of our solar system, causes currents, waves, and tides. Together these forms of thermal and mechanical energy make up a huge energy resource. You can regenerate/transform the forms of energy into others. 

I hope you got some idea!
