WIND ENERGY SOLUTIONS
Battery World is one of the most reliable suppliers of wind energy products in the region. Wind turbines of all sizes have become a familiar sight around the world for a wide variety of reasons, including their economic, environmental, and social benefits.
Wind energy is clean and renewable and as one of Mother Nature’s gifts; the wind is available and plentiful and won’t deplete our world’s natural resources.
Electricity generated by wind turbines won’t dirty the air we breathe or emit pollutants like other energy sources—that means less smog and less acid rain
Wind energy is reliable and efficient. Unlike other power plants, wind energy systems require minimal maintenance and have low operating expenses.
APPLICATION/ BENEFITS OF WIND ENERGY
- Clean Electricity: Widespread wind development addresses climate change by providing a non-polluting source of energy which contributes to global climate change. Wind energy is pollution free.
- Installed for lighting in residential homes, schools, community buildings, hospitals/medical centers and hotels/lodges/clubs.
- Energy Independence: Wind generation promotes national security by reducing our reliance on foreign and volatile sources of fossil fuels.
- Strengthens Rural Communities: Locally-owned wind generates new income sources for farmers, landowners, and communities. It also strengthens rural and often depressed communities in more subtle – yet important – ways by expanding local entrepreneurial ingenuity and fostering a sense of hope for the future.
- They can also be installed for water pumping.
- Are ideal if used in a “hybrid” system in conjunction with solar or generator.
- Stimulates the Local and State Economy: Community-owned wind projects provide high quality jobs, creating and retaining wealth that can then be re-invested in the community to grow new business opportunities.
- Strengthens Personal Responsibility: Wind turbines connect people to the source of their electricity, which characteristically inspires them to become more efficient and even more environmentally responsible.
- Free Fuel: Unlike other forms of electrical generation where fuel is shipped to a processing plant, wind energy generates electricity at the source of fuel. Wind is a native fuel that does not need to be mined or transported, taking two expensive aspects out of long-term energy costs.
- Price Stability: The price of electricity from fossil fuels and nuclear power can fluctuate greatly due to highly variable mining and transportation costs. Wind can help buffer these costs because the price of fuel is fixed and free.
- Creates Jobs: Wind energy projects create new short and long term jobs. Related employment ranges from meteorologists and surveyors to structural engineers, assembly workers, lawyers, bankers, and technicians. Wind energy creates 30% more jobs than a coal plant.
- Clean Water: Turbines produce no particulate emissions that contribute to mercury contamination in our lakes and streams. Wind energy also conserves water resources. For example, producing the same amount of electricity can take about 600 times more water with nuclear power than wind, and about 500 times more water with coal than wind
Wind-powered electrical generators.
A wind turbine is a popular name for a device that converts kinetic energy from the wind into electrical power. Technically, there is no turbine used in the design, but the term appears to have migrated from parallel hydroelectric technology (rotary propeller). The correct description for this type of machine would be aerofoil-powered generator.
The result of over a millennium of windmill development and modern engineering, today’s wind turbines are manufactured in a wide range of vertical and horizontal axis types. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs. Slightly larger turbines can be used for making contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Arrays of large turbines, known as wind farms, are becoming an increasingly important source of renewable energy and are used by many countries as part of a strategy to reduce their reliance onfossil fuels.
HOW DO WIND TURBINES WORK?
Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Click on the image to see an animation of wind at work.
So how do wind turbines make electricity? Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. View the wind turbine animation to see how a wind turbine works or take a look inside.
Wind is a form of solar energy and is a result of the uneven heating of the atmosphere by the sun, the irregularities of the earth’s surface, and the rotation of the earth. Wind flow patterns and speeds vary greatly across the country and are modified by bodies of water, vegetation, and differences in terrain. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.
The terms wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.
TYPES OF WIND TURBINES
Modern wind turbines fall into two basic groups: the horizontal-axis variety, as shown in the photo to the far right, and the vertical-axis design. Horizontal-axis wind turbines typically either have two or three blades. These three-bladed wind turbines are operated “upwind,” with the blades facing into the wind.
Wind turbines can be built on land or offshore in large bodies of water like oceans and lakes.
SIZES OF WIND TURBINES
Utility-scale turbines range in size from 100 kilowatts to as large as several megawatts. Larger wind turbines are more cost effective and are grouped together into wind farms, which provide bulk power to the electrical grid. In recent years, there has been an increase in large offshore wind installations in order to harness the huge potential that wind energy offers off the coasts
Single small turbines, below 100 kilowatts, are used for homes, telecommunications dishes, or water pumping. Small turbines are sometimes used in connection with diesel generators, batteries, and photovoltaic systems. These systems are called hybrid wind systems and are typically used in remote, off-grid locations, where a connection to the utility grid is not available.
