1. INTRODUCTION TO RENEWABLE SOURCES OF ENERGY The idea of drawing our energy from sources that are renewable, are independent of

foreign nations, and do not emit greenhouse gases has powerful appeal. But capturing these

resources is expensive, and many are intermittent, which complicates using them on a large

scale. Learn about renewable sources’ current contributions to our energy supply and their

prospects for our energy future. This energy as electricity plays a very important role in today’s

life.

Without electricity we are denied healthcare, sanitation services, and the social,

educational, economic, scientific, agricultural progress, etc. It comes from many sources. Some

of them are renewable and some of them are non-renewable. Renewable energy is an energy that

comes from resources which are naturally replenished such as sunlight, wind, rain, tides, waves

and geothermal heat.

2. WIND POWER

Wind power is the conversion of wind energy into a useful form of energy, such as

using wind turbines to produce electrical power, windmills for mechanical

power, windpumps for water pumping or drainage, or sails to propel ships. Large wind

farms consist of hundreds of individual wind turbines which are connected to the electric power

transmission network.

For new constructions, onshore wind is an inexpensive source of electricity, competitive

with or in many places cheaper than fossil fuel plants.[1][2]

Offshore wind is steadier and stronger

than on land, and offshore farms have less visual impact, but construction and maintenance costs

are considerably higher. Small onshore wind farms can feed some energy into the grid or provide

electricity to isolated off-grid locations.Maximum availability of the wind turbine system is

secured through the perfect interaction between the various products and systems.

The above figure shows the generation of electricity using wind energy.

4. INTRODUCTION TO SIEMENS WIND POWER

Siemens Wind Power has set itself a clear goal: to lower the cost of generating one

Kilowatt-hour (kWh) of onshore wind power to less than five euro cents by the end of the

decade. That would put wind power on a par with traditional energy sources. By comparison, a

kilowatt-hour of wind power now costs around seven cents, depending on the location in

question. Siemens also believes the price of electricity produced by offshore facilities needs to be

substantially reduced, since it’s currently around twice as high as the onshore price. The

company’s target is therefore to lower the price to less than ten cents per kWh, which would

make offshore wind power competitive.

“Over the last few decades, the auto industry has optimized vehicle components to such

an extent that they can now be manufactured as cheaply as possible”.

Siemens is the only company that manufacturers blades up to 75 meters long as a single

component. Thanks to this patented Integral Blade Technology, the rotor blades have no seams,

which means there are no weak points. As a result, they can reliably resist wind and weather for

at least 20 years. Following is the logo of Siemens Wind Power.

5.1. OFFSHORE

Siemens offers unrivaled experience and reliability in offshore wind power. We have a

proven track record in delivering offshore projects, from the world’s first offshore wind farm

more than 20 years ago to the largest offshore wind power plant in operation today. All our

projects deliver high availability. Optimized processes across the entire project life cycle make

us a stable, reliable, and trustworthy business partner. Over the years, our turbines have set the

standard for robustness and reliability. Designed with offshore applications in mind, they feature

a rugged, structurally conservative design, automatic lubrication systems with ample supplies,

climate control of the internal environment, and a simple generator system without slip rings.

These and many other high-quality design features provide exceptional reliability, with long

service intervals. Our turbines are built to last

5.2. ONSHORE

Demand for electricity generated from renewable sources is growing fast, and Siemens

has the answers. We are one of the world’s leading suppliers of onshore wind power solutions.

As one of the market leaders, we combine technological innovations, experience, and expertise

to deliver readily available, one-stop solutions and have a proven track record of successfully

delivering wind power projects on all continents. This makes us a reliable business partner and

preferred supplier for onshore wind power projects around the globe.

Over the years, our wind turbines have set the standard for robustness and reliability.

Designed with the most demanding applications in mind, they combine high-quality components

with a rugged, conservative structure and mechanical systems designed for low maintenance.

Fewer unscheduled services, better serviceability, and well-sourced spare parts reduce

operational costs.

Our onshore wind turbines can help yield substantial capital expenditure savings thanks

to their unparalleled electrical capabilities and superior SCADA flexibility, which can help

reduce interface costs. The unique NetConverter system, a standard feature of all our onshore

wind turbines, allows highly flexible generator operation and can help adapt power output to

different grids.
