What is one way in which fossil fuels and wind power are different?
Fossil fuels are non-renewable sources of energy, while wind power is a renewable source of energy. Fossil fuels contribute to air pollution and climate change through carbon emissions, whereas wind power is clean and does not produce greenhouse gases during operation.
Although the wind does not blow all the time, we know that every year the weather patterns repeat themselves, wind has never failed and will always be there to provide energy. It is produced by the sun's energy acting on the atmosphere, and we do not need to question whether the sun's energy is renewable.
To add to that, wind power is renewable because the wind can never "run out" (and is a product of the Coriolis Effect, caused by the rotation of the earth and heat convection in the atmosphere, both natural phenomenon), so it can constantly be harnessed and used for the generation of electricity

Does the wind blow all the time?
No, the wind does not blow all the time. It depends on weather conditions and atmospheric pressure gradients. Wind is the movement of air from areas of high pressure to areas of low pressure, so it is not always present.
How much energy does wind produce?
The amount of energy produced by wind depends on various factors such as wind speed, turbine size, and location. On average, a single wind turbine can generate enough electricity to power around 1200 households per year. Overall, wind energy contributes around 8% of the total electricity generation in the United States.
Wind helps us by generating clean and renewable energy through wind turbines, which can provide electricity for homes, buildings, and communities. Wind can also cool down the environment and help disperse pollutants in the air, improving air quality. Additionally, wind can be harnessed for recreational activities like sailing and kite flying.
Where does wind power come from?
Wind power is generated by harnessing the kinetic energy produced by the movement of air. As wind blows, it turns the blades of wind turbines, converting the energy into electricity. Wind power is a renewable energy source that is abundant and clean.
How much energy do wind turbines produce a year?
This depends on the size of the turbine and the wind resource. A single 1MW turbine operating at a 45% production rate will generate about 3.9 million kW of electricity in a year. This would be enough to meet the needs of about 500 households per year.
The world's largest turbine, the Enercon E-126 has a rated capacity of 7.58 MW have been constructed at Emden, in Germany in 2007. Several companies are developing 10 MW turbines.
A:Once you take away the wasted fossil fuel for plants on standby, the cost of maintenance and the inefficiencies associated with the wind turbines of today you end up with about 5% of rated power. Even when running they average 8% of rating.A 1 million watt system will typically generate about 80,000 watts of power each hour. This is further offset when you add into the equation that a power plant is running in the background to supply the backup power as wind velocities change. This is further offset when you add into the equation that a power plant is running in the background to supply the backup power as wind velocities change.
Units range in size from 400 watts to a 5 megawatt system. As systems increase in size they reduce efficiency and kill more birds and bats (Massachusetts loses 100K birds a year to wind systems),
Once everything is added up they produce less power then it takes to build a unit.
A:The World Wind Energy Association, an industry organization, reported that in 2010, wind power had the capacity to generate 430 TWh annually. This is about 2.5% of total energy generated worldwide.(430 Terawatts is 430 million million kilowatt hours: 430,000,000,000,000 kWh)
What are the positive aspects of wind energy?
Wind energy is a clean and renewable energy source that helps reduce greenhouse gas emissions and combat climate change. It is abundant and widely available, making it a sustainable option for generating electricity. Wind farms can also create jobs in the construction, maintenance, and operation of the turbines, contributing to local economies.
How is wind energy converted into electrical energy?
When wind turns turbines, the turbines wheels turn belts, which in turn turns a generator. Inside the generator, a coil of copper spins between a couple of magnets. This creates an electrical field, which is made into DC current. The DC current passes through multiple rectifiers that convert the DC current into AC. AC is the type of current a typical household outlet uses. Then, the AC current runs to either your home or a power plant for distribution across several neighborhoods.
Explain the orignal source of energy for both coal and wind?
The original source of energy for coal is the sun, which captured through photosynthesis by plants that later formed into coal over millions of years. The original source of energy for wind is the sun as well, as uneven heating of the Earth's surface causes air to move, creating wind.
What is the belt of winds that carries the polar storm track called?
The belt of winds that carries the polar storm track is called the polar jet stream. It is a high-altitude, fast-flowing air current that influences weather patterns in the mid-latitudes.
For what reasons is wind power better than fossil fuels?
Wind power does not harm the envoirment
no fossil fuels are burned in the making of energy with wind power = ] i think haha
__________
They are non-polluting, renewable and efficient. Not only does the use of renewable energy sources help reduce global carbon dioxide emissions, but they also add some much-needed flexibility to the energy resource mix by decreasing our dependence on limited reserves of fossil fuels. The wind turbines can effectively generate energy as electricity for free as long as the wind is available. The wind is free and renewable, which gives an advantage compared to the contaminating fossil fuel that have already done damage to the earth's ecology.
Wind turbines will also start to make a profit if used commercially.
Unlike fossil fuels, after you've paid for the turbine they start to make energy which can be sold on to the nation grid for example. In time the amount paid for the turbine would have been recovered and then you're making money using the free energy of the wind. Cool!
Wind power works by capturing the energy from the wind with wind turbines. When the wind blows, it causes the turbine blades to spin, which drives a generator to produce electricity. This electricity can then be used to power homes, businesses, and other structures.
Professor James Blyth built the first windmill for electricity production in 1887 in Glasgow, Scotland. He harnessed the wind power and charged accumulators, which in turn were used to power his holiday cottage. He later built a similar design to power an asylum in Montrose.
How much energy can wind power produce?
The amount of energy that wind power can produce depends on various factors, including the size and efficiency of the wind turbines, the wind speed at the location, and the availability of wind resources. On average, a single large wind turbine can generate enough electricity to power hundreds of homes, while large wind farms can generate electricity for thousands of households.
How is air used to generate energy?
Air/wind can turn a fan or windmill that is connected to a generator in the same way that water is converted to steam in order to turn a turbine. Air, and more specifically wind, is used to power windmills, that cause a turbine to turn, and generate electricity.
How much energy is wasted for every 1000 megajoule?
It depends on the efficiency of the appliance. If an electric motor has an efficiency of 0.7, then for every 1000 megajoules, 30 megajoules will be wasted as useless heat or sound or other useless energy form.
How much energy does wind power produce?
The amount of energy produced by wind power has several different factors, such as the amount and strength of the wind. However, some studies show that a 1.8 MW wind turbine can produce over 4,700,000 kWh of energy per year if located at a reasonable site.
What is good electric power for a house?
If your house has 220vac each leg should have at least 110vac so if you use an electric dryer you would have 110 vac to each leg to run the dryer for outlets and switches it would be the same 110vac volts alternating current to operate electrial devices and to turn the lights on and off.
Heat energy from the Sun causes the variety of weather patterns responsible for creating winds, including "prevailing" winds which are used for locating and powering wind generator "farms."
It is significant to ask this question as the two main types of wind turbines are horizontal and vertical, and these designs use the wind in slightly different ways regarding the wind energy harnessing process.
Horizontal wind turbines are the more common design, and use angled propeller type blades to create friction when facing the wind, resulting in the spinning motion.
The vertical axis design uses the wind to spin on a centre point on the ground, resulting in the whole construction spinning round.
The process of electricity production is significantly similar in both designs. The construction only makes a difference in the position and design of the blades which are used to create friction with the wind.
A large mass of air moving over the landscape represents a considerable amount of energy. By building devices that will spin when the wind blows, it is possible to harness some of that energy. Most modern wind turbines are several hundred feet high, with propellers that have 3 blades, each one about 150 long.
What is wind energy potential?
Wind energy potential refers to the amount of energy that can be generated from harnessing wind power in a specific location. Factors that determine wind energy potential include wind speed, consistency, and direction. Areas with high wind energy potential are ideal for the development of wind farms to generate electricity efficiently.
Has Nuclear Energy changed over time?
Nuclear energy was first demonstrated by the Chicago Pile 1 in 1942, under Fermi, but this experiment did not produce any useful power. Power producing reactors were built in the US and UK in the mid '50s, and other countries have followed. Since then the principles of using heat generated by fission of U235 (mainly) to drive the normal type of steam turbines and produce electricity have stayed the same. Development has been largely to make plants more efficient and improve safety.
What type of energy does a fuel possess?
A fuel possesses chemical energy, which is released when the fuel undergoes a chemical reaction such as combustion. This chemical energy is then often converted into thermal energy or mechanical energy to perform work.
