With the development of industry and
agriculture, a great amount of energy such as coal, oil
and gas has been consumed in the world. Extensive
use of these fossil energies deteriorates a series of
problems like energy crisis, environmental pollution
and so on. Everybody knows that the fossil energy
reserves are finite, some day it will be exhausted.
It is possible that the world will face a
global energy crisis due to a decline in the
availability of cheap oil and recommendations to a
decreasing dependency on fossil fuel. This has led to
increasing interest in alternate power/fuel research
such as fuel cell technology, hydrogen fuel, biodiesel,
Karrick process, solar energy, geothermal energy,
tidal energy and wind. Today, solar energy and wind
energy have significantly alternated fossil fuel with
big ecological problems.
With the development of the science and
technology, power generation using solar energy and
wind power is gradually known by more and more
people. And it is widespread used in many developed
countries. The merits of the solar and wind power
generation are very obvious-infinite and nonpolluting.
The raw materials of the solar and wind
power generation derived from nature, and wind
power generation can work twenty-four hours a day,
solar power generation only works by daylight. In
addition, this kind of power generation has no
exhaust emission and there is no influence to the
nature. But it also has some shortcomings. Because
of the imperfect of the technology, equipment of the
solar and wind power generation is very expensive.
By far, it cannot be widely used.
In addition, solar and wind power
generation system affected by the changing of the
weather very much, so it has obvious defects in
reliability compared with fossil fuel, and it is difficult
to make it fit for practical use the lack of economical
efficiency .Because of these problems it needs to
increase the reliability of energy supply by
developing a system which interacts Solar and wind
energy. This kind of system is usually called windsolar

This report gives an overview of patenting activity around Doubly-fed Induction Generators (DFIG) used in the horizontal axis wind turbines for efficient power generation. Patents were categorized as per key DFIG technologies and analyzed for generating different trends within PatSeer Project.
Sea waves have high energy densities, the highest among renewable energy sources with the natural seasonal variability of wave energy following the electricity demand in temperate climates securing energy supplies in remote regions.
1. INTRODUCTION
In the future, the cost of energy will increase due to environmental problems and limited resources. The electric motor consumes major part of the electric energy in the industry. The induction motor is the main driven system in the modern industrial society. It would also reduce the production of greenhouse gases and push down the total environmental cost of electricity generation. Also these motors can reduce maintenance costs and improve operation in industry. Energy efficient motors use less electricity, run cooler, and often last longer than NEMA (National Electrical Manufacturers Association) B motors of the same size.
Motors and motor-driven systems account for 43%-46% of all global electricity consumption and 69% of all electricity used by industry. Inefficient electric motors waste electrical energy and therefore cost more to operate. Since most electricity is generated from fossil-fuelled power plants, motors and motor-driven systems are also indirect contributors to greenhouse gas emissions produced by these plants. Hence, there are compelling economic and environmental reasons to increase the use of energy efficient motors.

Renewable energy sources, unlike the conventional combustible fuels, are naturally distributed and extensively available in a boundless manner all over the world in different forms. Here, in this paper, authors elucidate the scopes and opportunities of the ocean wave to develop a low-cost, environmental friendly, and sustainable electrical power generation system. At the present time most technological modernizations aimed at exploiting such resources are at early stage of development, with only a handful of devices close to be at the commercial demonstration stage. None of them, though, operates converting the wave energy contents at its very origin: the orbital motion of water particles right below the ocean surface. The Sea spoon device catches the kinetic energy of ocean waves with favorable conversion proficiency, according to specific "wave-motion climate". In this letter, authors illustrate a possible methodology of converting this naturally exorbitant energy with efficient conversion methodology and simulating the conversion environment with MATLAB/Simulink platform.

Introduction
In reaction to the requirement to discover supplementary agents of renewable fuel to contend climate adjustment, make sure of domiciliary fuel safety along with advance fresh industries a big society of wave fuel surveyors and mercantile machine advancers has arisen in contemporary years, in pursuance of a substantial amount of various technologies for the regeneration of wave fuel. The concentration has mostly been put on machines located seaward, in greater waters, because of the anticipated gain of the greater gross fuel degrees experienced there. (Karimirad, 2014). Nonetheless, there are several conventionally omitted gains related to the near shore ecology that make it a desirable weather for an effectively schemed wave fuel generator.
Aquamarine Energy Ltd was created in the year 2005 to create Oyster, a device that interplays appropriately with the domineering flow forces experienced in the near shore current weather at intensities of 10 to 15 m. The Oyster theory uses a broad floatable basal-hinged fold that totally breaks in the aqua row from on top of the covering to the sea bottom. The current speed on the oscillator, from the swelling activity of currents, moves hydraulic generators that compel aqua and distend it to coastland via water passages. The inshore hydroelectric machinery changes the hydraulic thrust to dynamic fuel through a Pelton disk, which moves a dynamic alternator. The aqua goes back to the machine in a sealed ring through an additional low thrust reversion water passage.
Aquamarine energy conveniently put up a 315kW complete range proof of theory machinery at EMEC in the year 2009. After conclusive conjunction and induction, initial energy was attained in the same year in the month of October. The plan titled Oyster 1, has been bringing forth invaluable achievement and charging information which will be the concentration of a coming publishing.
A comprehensive collection of tank examinations along with statistical is being performed so as to make better the coming conception of Oyster machinery. This fresh model comprises of several performance advancements which will put the electronic components in near scope of a commercial project. Oyster two is made up of triple next life seaward current seizure units with complete generation ability in surplus of 2 MW. A prosperous affirmation plan at this scale is needed to show the proof for the electronic components decreasing technical along with functional threats connected to the extensive dispositions to a degree which is commercially appealing to established venture capitalists. (Lynn, 2014). Oyster 2 is presently in the definite model stage and was put up at EMEC in the year 2011.

A review of wave energy converter technology
By : B Drew , A R Plummer , and M N Sahinkaya
Department of Mechanical Engineering , University of Bath , Bath , UK
4. Abstract:
Ocean waves are a huge, largely untapped energy resource, and the potential for
extracting energy from waves is considerable.
Research in this area is driven by the need to meet renewable energy targets,
but is relatively immature compared to other renewable energy technologies.
This review introduces the general status of wave energy and evaluates the
device types that represent current wave energy converter (WEC) technology.
Types of different wave energy converters and their working mechanism has been
described in this report.
Best areas in order to generate maximum energy .
This article concludes with some suggestions of future developments.
5. Introduction:
Despite being discussed in patents since the late 18th century [1], modern
research into harnessing energy from waves was stimulated by the emerging oil
crisis of the 1970s .
Wi0th global attention now being drawn to climate change and the rising level of
CO2, the focus on generating electricity from renewable sources is once again an
important area of research.
It is estimated that the potential worldwide wave power resource is 2 TW , with
the UK’s realistic potential being 7–10 GW .
To put these figures into perspective, the UK’s total grid capacity is 80 GW, with
peak demand stabilized at around 65 GW .
As such, up to 15 per cent of current UK electricity demand could be met by
wave energy; when combined with tidal stream generation, up to 20 per cent of
the UK demand could be met .
6. There are several reviews of wave energy converter (WEC) concepts (for
example, see references [2], [3], [6], and [7]). These show that many wave
energy devices are being investigated, but many are at the R&D stage
In September 2008, another commercial wave power system started operating in
Northern Portugal. It makes use of the Pelamis power generating device built by
Pelamis Wave (formerly OPD) in Scotland (see section 2.4.1 for more
information).
8. Sea waves offer the highest energy density among renewable energy sources.
Waves are generated by winds, which in turn are generated by solar energy. Solar
energy intensity of typically 0.1– 0.3 kW/m2 horizontal surface is converted to an
average power flow intensity of 2–3 kW/m2 of a vertical plane perpendicular to
the direction of wave propagation just below the water surface
Limited negative environmental impact in use. Thorpe details the potential
impact and presents an estimation of the life cycle emissions of a typical near
shore device. In general, offshore devices have the lowest potential impact.
3. Natural seasonal variability of wave energy, which follows the electricity
demand in temperate climates
Waves can travel large distances with little energy loss. Storms on the western
side of the Atlantic Ocean will travel to the western coast of Europe, supported
by prevailing westerly winds
It is reported that wave power devices can generate power up to 90 per cent of
the time, compared to ∼20–30 per cent for wind and solar power devices
9. Wave energy converter :
There is a large number of concepts for wave energy conversion; over 1000
wave energy conversion techniques have been patented in Japan, North
America, and Europe. Despite this large variation in design, WECs are
generally categorized by location and type.
10. Wave climate :
In order to assess an area for wave energy
development, the wave climate must be defined.
The wave climate describes an area’s wave
height distribution, wave length distribution, and
total mean water depth.
From these parameters, one can compute wave
power levels.
11. Types:
Despite the large variation in designs and concepts, WECs can be classified into
three predominant types:
Attenuator
Point absorber
Terminator
12. Attenuator:
Attenuators lie parallel to the predominant wave direction and ‘ride’ the waves
.An example of an attenuator WEC is the Pelamis , developed by Ocean Power
Delivery Ltd (now known as Pelamis Wave Power . Figure shows an artist’s
impression of a Pelamis wave farm.
13. Point absorber :
A point absorber is a device that possesses small dimensions relative to the
incident wavelength. They can be floating structure that heave up and down on
the surface of the water or submerged below the surface relying on pressure
differential. Because of their small size, wave direction is not important for
these devices. There are numerous examples of point absorbers, one of which is
Ocean Power Technology’s Powerbuoy . Figure shows an artist’s impression of a
wave farm using Powerbuoys.
14. Terminator :
Terminator devices have their principal axis parallel to the wave front
(perpendicular to the predominant wave direction) and physically intercept
waves. One example of a terminator-type WEC is the Salter’s Duck as shown
in the figure.
15. Conclusion:
The potential for generating electricity from wave energy is considerable. The
ocean is a huge resource, and generation the electricity from ocean waves
represents an important step towards meeting renewable energy targets.
This review introduces the current status of WEC technology.
The different device types are established and evaluated.
The institutions and companies involved in WEC development, as well as
collaborative wave energy projects, are also identified.
The possible PTO (power take off) systems are assessed and classified as
hydraulic, linear electrical generator, or turbine based. A hydraulic PTO system is
particularly well suited to absorbing energy from a high force, slow oscillatory
motion and can facilitate the conversion of reciprocating motion to rotary motion
to drive a generator. There are, however, various design challenges such as
efficiency and reliability.
16. A linear electrical generator provides an alternative option, but the technology is less
mature. The active control of a WEC can significantly increase its efficiency, and hence
cost effectiveness. This research is currently ongoing with latching control being
highlighted as a promising, simple method of efficiently extracting energy.
Despite considerable research and development, the concepts for converting a slow,
high-force, reciprocating motion to one useful for generating electricity show no signs
of converging to a preferred solution. Questions arise over which concept to use, how
best to optimize its performance, and how to control such a system. Future research
should take a systems engineering approach, as the individual subsystems of a WEC are
all intimately related and any one should not be optimized without considering the
other subsystems. Furthermore, individual WECs will often operate as part of a wave
farm, so future systems analysis must include the interaction between devices.
