its for my science project

Answer by Thomas C
A modern wind turbine has a capacity of 1.5 to 2.5 MW. Unfortunately they don't run continuously, much less at maximum capacity.

Since this is your science project, I'll let you do most of the research. Here are some of the items you'll need.

1) Annual kWh consumption of the "average" home.
2) Installed capacity of wind turbines.
3) Average capacity factor of wind turbines. (25 to 40%)

You need to decide whether your research is going to be just the US or world-wide.

Question by Tahini Classic: Is there a forum for people who want to build their own wind turbines and generators and stuff?
I am looking for some website or forum where I can discuss the nitty-gritty of making wind turbines and building anything that enables people to go off the grid and build their own boats, heat sources, alternative fuels, all-natural materials, etc.
Would anyone know where to find that?
Thanks.

Question by Hobgoblin66: Installation of GE 1.5MW Wind Turbine Generators?
I work as an estimator for an electrical contractor. We are bidding a fairly large wind farm with GE 1.5MW WTGs. Can anyone give me an idea as to what is involved in their internal electrical connections? I would also like to know roughly how many man hours are involved?

Best answer:

Answer by rhsaunders
You should be able to get this information from GE. Among issues that will need to be dealt with are transformers, circuit breakers and disconnects, and wiring from the WTG's to a collection point whence the juice can go out to consumers.

Best answer:

Answer by Jacko
You can easily make one from an old stepper motor out of a printer, or a computer.
Just put a fan or a propeller on the shaft and that's it. If you want to produce DC, then you will need a rectifier as well.
This will probably take the form of 6 diodes, in order to get the maximum output.
Have a go, it won't cost anything.

Answer by Bruno K
Any type of electric motor will generate electricity when turned. The bigger it is (probably) the more electricity it will generate. Make sure it's electric, not gas powered.

Global Market for Electric Motors and Commercial Generators to Reach US$73.2 Billion by 2015, According to New Report by Global Industry Analysts, Inc.

Global Market for Electric Motors and Commercial Generators to Reach US$ 73.2 Billion by 2015, According to New Report by Global Industry Analysts, Inc.

San Jose, California (PRWEB) January 18, 2012

Follow us on LinkedIn – Motors and generators find application in diverse end-use industries including manufacturing, industrial, chemicals, petrochemicals, automotives, and energy generation, among others. Government legislation and environmental concerns are the major demand drivers for higher efficiency motors and generators in developed countries, while the robust economic growth is fuelling the appetite for technology upgradation in developing countries. The rapid pace of industrialization and the resulting demand for electric power, fuel and minerals is driving demand for motors and generators in emerging countries. The recent economic recession negatively impacted the market. For instance, demand for energy is closely tied to the level of economic activity, and the recession not surprisingly resulted in lowering consumption as major energy-consuming sectors such as manufacturing, automobiles and construction industries. All of these factors negatively impacted sales of electric motors and generators in the power generation end-use industry. Reduced industrial, manufacturing and commercial activity elicited a parallel reduction in demand for electric motors in industrial processing and manufacturing sectors.

Currently, however the motors and generators market is staging a recovery with growth being spearheaded by emerging countries. Globally there is an increasing momentum being witnessed towards the adoption of eco friendly and cost saving products. This trend is reflected even in the electric motors industry as the industry is gradually shifting towards energy efficient motors and adopting various energy efficiency standards. High-efficiency motors, otherwise known as premium efficiency motors, are eliciting interests from both manufacturers and customers. With government directives requiring motor manufacturers to toe on the similar line to meet efficiency requirements, there exists increased focus towards developing energy efficient products. Such directives are thereby compelling motor manufacturers to offer superior products along with energy efficiency features.

North America leads the world in adopting the legislation mandating the use of high-efficiency (IE2) and premium-efficiency (IE3) motors, while Europe and several other countries are preparing to do so in the near term. The huge replacement market thus created is expected to stimulate the demand for motors for the near term. The market for low and medium-voltage industrial motors and drivers slumped in 2009 following a dip in fresh orders and the liquidity crunch, and is rebounding with the recovery in the global economy, as well as expanding scope of applications in diverse sectors. Metals and mining, power generation, marine and oil and gas industries are the centers of demand for large motors. The growing popularity of electric vehicles is also expanding the scope of electric motors in the automobile industry. In addition DC motors are finding increasing application in automobile interiors due to the ongoing automation of manual functions in vehicles.

The generator market on the other hand is driven by the rapidly expanding global population, as well as macroeconomic trends such as industrialization, and urbanization. Construction and telecom sectors are the major growth drivers for the industry. The demand is strongest in the Asia Pacific, Latin American, Middle East and African nations due to the rapid growth of industry and relatively poor electricity distribution infrastructure in these regions. Due to the ageing power infrastructure and the large number of natural calamities in recent times, the requirement for power generation systems is rising in US and Japan among other countries. Moreover, with the expansion of cities the residential use of generators is also rising. Diesel generators are giving way to alternate fuels such as kerosene and compressed gas, as well as renewable energy power sources such as solar, wind and biomass power.

Although the US and Europe together account for about half of the global market for electric motors, the Asia pacific region leads the growth in the industry, closely trailed by Latin America and other emerging countries. Due to the rapid industrialization and strong GDP growth in China and India among others, the Asia Pacific generators market is the largest as well as the fastest growing region for the global generators market.

The research report titled “Motors and Generators: A Global Outlook” announced by Global Industry Analysts, Inc., provides a collection of statistical anecdotes, market briefs, and concise summaries of research findings. The report offers a rudimentary overview of the industry, highlights latest trends and demand drivers, in addition to providing statistical insights. Regional markets briefly abstracted and covered include United States, Japan, China, India, Russia and South Africa among others. The report offers a compilation of recent mergers, acquisitions, and strategic corporate developments. Also included is an indexed, easy-to-refer, fact-finder directory listing the addresses, and contact details of companies worldwide.
