Wind Energy Technology: Innovations and Challenges

Carsten Westergaard [Global Technology Director, Vestas] Abstract: Wind energy is a fascinating collection of multi-disciplinary engineering. Harvesting the wind efficiently, we have to understand the metrological conditions, the climate, and the turbulence induced by the landscape in order predict the lifetime performance parameters. We can design the turbines using all of our knowledge from civil, mechanical and electrical engineering to deliver a cost-efficient energy that can compete with other energy sources in todays modern society. Now, the goal of the United States is to have 20% of the electrical energy generated by wind. We will need to understand the logistic chain and the infrastructure required to install and operate turbines. Vestas currently has a fleet of more than 35000 turbines, and we are installing one turbine every four hours somewhere on the planet. Biography: Dr. Carsten Hein Westergaard earned his PhD in 1994 at the Danish Technical University. His dissertation titled: “PIV measurements of turbulent structures” encompassed optical computing and optical flow measurements. Part of his research was completed with Prof. Ronald Adrian at University of Illinois. He started his industrial career in wind technology as an aerodynamics blade designer. Through the years, he has been working with fluid and structure dynamics in many different industries. Joining Vestas Technology R&D, he started Vestas office on campus of the National Laboratory for

What Exactly Is Alternative Energy

There is alot of talk about where will the energy for that future come from. Where will the kids of growing up today find their sources of power. How will they get power and what will it price them? I do not know for sure but can tell you about some things which are recognized presently in the year 2010.

There is a whole lot of energy that we can use if we only look for to research and develop the technology needed to complete so. We could get away from the traditional fuels and the old power grids by converting to alternatives to these power sources.

One of these option power resources is wind power. Wind turbines continue to become developed which are progressively more power efficient and much less costly. “Wind farms” happen to be springing up in numerous nations, and they have even become more strategically placed more than time to ensure that they aren’t jeopardizing birds as former wind turbines did.

Another alternative power resource is the one that’s most well recognized: solar power. This involves the production of solar cells which gather and concentrate the power provided off directly by the sun, and translate it into electrical power or, in some cases, hot drinking water. As with wind power, solar power produces totally zero pollution.

Ocean wave power is observed by governments and investors as getting enormous energy generating possible. A generator in France has been in operation for many years now and is considered to be a excellent success, and also the Irish and Scots are running experimental facilities.

Hydroelectric energy has been with us for a while and exactly where it’s set up, it is really a powerful generator of electricity and cleaner than a grid. However, there are certain limitations towards the availability of the right places to set up a big dam. Numerous run-of-the-river, or little and localized, hydroelectric generators happen to be set up in latest times because of this limitation.

Geothermal energy is very abundant, since it lies straight beneath our feet, just several miles below the earth’s surface. This power is created through the heating of water via the actions of earth’s fantastically warm molten core. The water turns to steam, which could be harnessed and utilized to drive turbine engines which in turn generate electricity. Excellent quantities of research and development should be put into geothermal power tapping.

Waste materials gas energies, which are basically methane, reverse the typical energy-pollution relationship by creating energy from waste that lies within the dumps and from some air pollutants. This gas is used in energy cells and can be utilized in regular gasoline generators.

Ethanol is a gasoline substitute and is created from such things as wheat, sugarcane, grapes, strawberries, corn, and even wood chips and wood cellulose. There’s controversy over this energy with regards to its ever getting truly economical or practical except in really localized areas, but technologies for its extraction and admixturing are continuously becoming refined. There aren’t that many options for energy efficient automobiles but you will find some car and truck accessories that can help to preserve energy.

Biodiesel energy is produced out with the oils contained in plants. So far, the commercial shops of biodiesel happen to be produced using soybean, rapeseed, and sunflower oils. At the time of this writing, biodiesel is usually created by entrepreneurial minded individuals or people who wish to experiment with option energy, but commercial interest from businesses is about the rise. It burns a lot cleaner than oil-based diesel.

Atomic power is created in atomic energy plants utilizing the procedure of nuclear fission. This power is extremely effective and can generate large amounts of energy. There’s concern from some individuals about what to complete using the relatively little amount of waste item atomic power gives off, because it is radioactive and takes hundreds of years to decay into harmlessness.

The Ways That The Military Is Using Alternative Energy

The US army knows that its branches must revamp their considering about how you can engage in “the theater of war” within the new, post-Cold War globe with the 21st century. A single point how the army leaders stress may be the desire for that forces deployed in the theater to be able to be much more energy-independent. Presently the US military has policies and procedures in location to interact with allies or sympathetic nearby populaces to assist its forces in the area get their needed power and clean water when engaged in a foreign military campaign. However, this isn’t wholly reliable, as the US may nicely discover by itself facing unilateral military activities, or have by itself in a scenario where its allies cannot help it with the resources it needs to conduct its military actions successfully.

The US military is very enthusiastic about certain Alternative Energy that, with the correct research and development technologically, can make it power independent, or a minimum of a great deal more so, on the battlefield. Among the things that greatly interests the military along these lines is the development of small nuclear reactors, which might be transportable, for generating theater-local electricity. The army is impressed with how clean-burning nuclear reactors are and how energy effective they are. Creating them portable for that standard warfare of today’s extremely mobile, small-scaled military operations is some thing they’re researching. Probably the most prominent point how the US army thinks these little nuclear reactors would be helpful for involves the removal of hydrogen (for fuel cell) from seawater. It also thinks that converting seawater to hydrogen fuel in this way would have less negative effect about the atmosphere than its present practices of remaining supplied out within the area.

Seawater is, actually, the military’s highest interest when it comes to the matter of energy supply. Seawater could be endlessly “mined” for hydrogen, which in turn powers sophisticated energy cells. Using OTEC, seawater may also be endlessly converted into desalinated, potable drinking water. Potable water and hydrogen for energy are two with the things that a near-future deployed army force will require most of all.

In the cores of nuclear reactors—which as stated above are devices extremely interesting, in portable form, to the US military—we encounter temperatures higher than 1000 degrees Celsius. When this level of temperature is mixed having a thermo-chemical water-splitting procedure, we have on our hands the most effective signifies of breaking down drinking water into its component parts, that are molecular hydrogen and oxygen. The minerals and salts that are contained in seawater would have to be extracted via a desalination procedure in purchase to make the way clear for that water-splitting process. These could then be utilized, for example in vitamins or in salt shakers, or merely sent back to the ocean (recycling). Utilizing the energy of nuclear reactors to extract this hydrogen from the sea, so that you can then input that into fuel cells to energy sophisticated airplanes, tanks, ground automobiles, and the like, is clearly higher on the R & D priority list with the military.

University Research Into Renewable Energy

Decades of tree and biomass research jointly conducted by Florida Statue College and Shell Power have resulted within the planting of the largest single “energy Crop Plantation” in the whole United States. This Plantation spans around 130 acres and is home to more than 250,000 planted trees such as cottonwoods (native to the region) and eucalyptus (which are non-invasive) along with various row crops such as soybeans. This organization of “super trees” was brought into becoming as a result with the University’s joint study with other agencies such as Shell, the US Department of Power, the Common Objective Institute, and groups of numerous people who are working to develop alternative energy sources (individuals not dependent on fossil fuels) for the future. This research is focused about the planting and processing of biomass power supplies from fast-growing crops known as “closed loop biomass” or simply “energy crops”. The project seeks to create “power plants” such as wood-pulp or wood-fiber providing plants; thoroughly clean biogas to be used by industries; plants such as surgarcane which could be utilized for ethanol improvement; and crops this kind of as soybeans for biodiesel fuel production.

University involvement in choice energy research can also be heading on at Penn Point out College. At Penn Point out, unique research is concentrated on the improvement of hydrogen energy like a practical choice energy supply. The researchers involved are convinced that mankind is moving toward a hydrogen-fueled economy due towards the requirements for us to reduce air pollution and discover other sources of energy besides petroleum to power up the United States. Hydrogen power burns thoroughly clean and could be endlessly renewed, since it could be drawn from water and crop plants. Hydrogen energy would therefore be a sustainable power resource to become found inside the US’ own infrastructure although the world’s supply of (affordable) oil peaks and begins to decline. The College seeks to help using the commercial improvement of hydrogen powered fuel cells, which will be usable in location of or in tandem with combustion engines for all of our motor automobiles and truck and car accessories that may conserve fuel.

When President Bush recently announced his alternative power initiative, he determined that the federal government would create 5 “Sun Grant” centers for concentrated study. Oregon Point out University has the honor of having been chosen as a single of these centers, and may be allocated federal government grants of $20 million for each of the following four many years in order to carry out its mission. OSU will lead the way in researching alternative power as it represents the interests of the Pacific Islands, the US’ Pacific Territories, and nine western states. OSU President Edward Ray says, the study being conducted through OSU’s Sun Grant center will contribute directly to our meeting President Bush’s challenge for power independence. Specific study into alternative energy becoming carried out at OSU by varios teams of scientists correct now consist of a task to determine how you can efficiently convert such products as straw into a source of renewable biomass fuel, and another one aimed at studying how you can efficiently convert wood fibers into liquid energy.

Wind Electrical Power As A Viable Solution To Meeting Option Energy Requirements

Even though it is a lot less pricey to initially get hooked in to the local electrical company’s grid than it is to setup and connect into wind turbines, in the long run 1 saves dollars by utilizing the wind for one’s Renewable Green Energy needs—while also becoming alot more independent. Not receiving an electric bill whilst enjoying the advantages in the modern electrically-driven lifestyle can be a wondrous feeling. Electric bills and fuel bills are rising steadily—but the cost of wind turbine vigor is zero, plus the charge of installing and hooking up a turbine is steadily coming down as demand rises and alot more commercial success is realized by a variety of organisations producing the turbines and researching technologies to make them ever even more efficient. Additionally, people are moving away in the traditional electric grids along with the fossil fuels for individual factors including wish for greater independence, the wish to live remotely or rurally without having having to “go primitive”, political concerns for instance fears of terrorist strikes on oil fields or electricity grids, or concerns about the environment.

Again, this motivation to get away from your common vigor sources is exactly the same one that causes citizens to seek the power from the wind for their energy, giving further company opportunities to profit from wind turbine production and maintenance, which drives their fees down for your consumers. In almost thirty states at the time of this writing, home owners who remain on the grid but who still choose to use wind electricity (or other choice forms) are eligible for rebates or tax breaks from your state governments that wind up paying for as very much as 50% of their total Green Energy costs. In addition, one can find 35 states at the time of this writing where these home owners are allowed to sell their excess energy back towards the energy business under what are known as “net metering laws”. The rates that they’re being paid by the local electric power businesses for this energy are standard retail rates—in other words, the home owners are in fact profiting from their own power production.

Some federal lawmakers are pushing to obtain the federal government to mandate these tax breaks and other wind energy incentives in all 50 states. Japan and Germany already have national incentive programs in place. However, “A lot of this is handled regionally by state law. There wouldn’t genuinely be a role for your federal government,” the Electricity Department’s Craig Stevens says. And as may be imagined, you will find power corporations who feel that it’s unfair that they should really must pay retail rates to private people. “We should [only have to pay you the wholesale rate for … your electricity,” according to Bruce Bowen, Pacific Gas & Electric’s director of regulatory policy. Then again, the companies seem to be a good deal more worried about losing short term profits than about the benefits, especially in the long run, belonging to the increased use of wind turbines or wind farms. Head belonging to the Center for Vitality Efficiency and Renewable Technologies of California V. John White points out, “It’s quality energy that strengthens the grid.” Hopefully the world can move to Renewable Energy within Renewable Green Energy to converse electricity and meet the needs belonging to the future.
