We consider that renewable sources to be the solution of all worries about power crisis in the world.

If we are able to apply the use of electronics in generation of power from sea waves and minimize the power loss then we will be able to save the depleting natural resources of our dear earth.

We think our team will be successful in conveying to the young generation that renewable resources are better sources of energy as compared to non-renewable resources

In today's world when non-renewable resources are exhausting at a deadly pace,the only alternative is to turn to renewable resources to compensate our needs.Sea waves are one of the best natural resources to generate power.Our earth has nearly 70% of its surface covered with water bodies and each nation can generate as much power it wants.Being easily available it can be easily brought to our use.Unlike hydropower and wind power where it disturbs both the ecology and also consumes space,sea wave power is much cleaner.The seas being large are unaffected by the space constraint unlike solar power plants which require huge amount of space.And it will also  much more constantly supply us with power as compared to other renewable sources like solar energy which is dependent on availability of sun to generate power.Initial researchs on power generation have yielded encouraging results.If proper work and more research is done on sea waves then it will alone solve the problem of power crisis in the world and will provide us with a long term solution of our needs.

1. An alternative source of energy

This form of energy if properly utilised, can be alternative source of

power to non-renewable sources of energy such as coal,etc.Being a

renewable source of energy power can be generated from it till we want.

The renewable sources are not able to satisfy the growing needs of mankind   There is a crisis of sources like oil,coal,etc.These problems could be solved through a

broad implementation of Wave energy technologies.

2. Will help to reduce our dependence on conventional sources

As we will move from conventional sources of energy to non-conventional sources of

energy,these conventional sources can be saved for a better future.An estimate about

sea wave power generation says that if we take this form of energy seriously then

energy that can be harvested from the world’s oceans is equal to twice the amount of

electricity that the world produces now. Such amount of clean, cost-efficient

energy will certainly assist the World’s green and economic development.

The main advantages of hydropower are:

A renewable source of energy - saves scarce fuel reserves. • Non-polluting and hence environment friendly. • Long life - The first hydro project of India completed in 1897 is still in operation at Darjeeling. • Cost of generation, operation and maintenance is lower than the other sources of energy. • Ability to start and stop quickly and instantaneous load acceptance/rejection makes it suitable to meet peak demand and for enhancing system reliability and stability. • Has higher efficiency (over 90%) compared to thermal (35%) and gas (around 50%). • Cost of generation is free from inflationary effects after the initial installation. • Storage based hydro schemes often provide benefits of irrigation, flood control, drinking water supply, navigation, recreation, tourism, pisciculture etc.

In order to compensate for sudden load fluctuations occurring in the micro grid, the EDLCs are used as the charge/discharge elements because they are capable of high-speed charging and discharging . The features of equipment are described below.

1) High-speed response Compared with storage batteries, the EDLCs are capable of high speed charging and discharging.

2) Long operational life after frequent charge/discharge actions Compared with storage batteries, the EDLCs can withstand frequent charge/discharge duty cycles. In addition, the operational life is long.

3) Generation of active power in high preference when fluctuations occur in active and reactive power at the same time, active power is output in higher performance.

4) Generation of a constant reactive power According to the reactive power command value sent from the supply and demand control system, it is possible to generate a constant level of reactive power burden to be shouldered by the generator.

I would like to share about a company called Pelamis and how it is generating power from sea waves.

It is the most advanced wave energy company and has already demonstrated its Generation 1 Pelamis Wave Generators off the coast of Portugal.It is now devlopeding a 25 MW wave energy farm off the same area using its Pelamis 2 Wave Generators which are more advanced. It was the world’s first commercial scale machine to generate electricity to the grid from offshore wave energy and the first to be used commercially.Alongwith giant German utility E.On it is testing a P2 Pelamis machine over three years at the European Marine Energy Centre (EMEC).The machine floats semi-submerged on the surface of the water and is made up of a number of cylindrical sections joined together by hinged joints.  As waves pass down the length of the machine these sections flex relative to one another.  The motion at each hinged joint is resisted by hydraulic cylinders which pump fluid into high pressure accumulators allowing electrical generation

Here's what I understood from my article:

Introduction:

This article illustrates the immense potential and uses of hydropower as a source of energy. It systematically lists the various facets of this source of energy.

It starts off with an in depth analysis of how hydropower works. Then we move on to the fact that hydropower is not always applicable as an energy source in every case. So we list out requirements for usage of hydropower as a viable energy source:

1) Determining 'head': which means we basically estimate the energy output that a site of hydroelectric power will generate based on scientific principles and calculations..

2) Determining Economic Feasibility: We next logically need to determine whether this site will be economically viable to us with respect to capital and expected output.

Specifics:

Later we go into the technical specifics of the system components of a hydroelectric power plant: channels, storage and filters; turbines and waterwheels; and studying the basic mechanics of the system such as impulse and reaction.

Then we get into the legal specifics of obtaining water and land rights for this project.

Finally we find out about the process to contact the utility to legally sell the generated power at a profit.

Conclusion:

In conclusion, from all the technical knowledge gathered, we observe that this is an extremely clean form of energy with a great potential for serving as a singular source of clean energy in the future.

How Does Ocean Wave Power Work?
Ocean waves are both clean and renewable sources of energy with a tremendous worldwide potential of generating electricity. If fully exploited, about 40% of the world’s power demand could be supplied by this resource – equivalent to as much as 800 nuclear power plants.

Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, air and water heating/cooling, motor
fuels, and rural (off-grid) energy services.

Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits. In international public opinion surveys there is strong support for promoting renewable sources such as solar
power and wind power. At the national level, at least 30 nations around the world already have renewable energy contributing more than 20 percent of energy supply. National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond.

While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. United Nations' Secretary-General Ban Ki-moon has said that
renewable energy has the ability to lift the poorest nations to new levels of prosperity.
