An Ever Growing Market
The market of renewable energies has been attracting more and more attention. As technology improves and it becomes cheaper, safer and more profitable to invest in wind energy, more companies and governments are turning their heads towards this drive of the energy transition.
As Europes biggest gas supplier Russia is being cut out of the picture due to the ongoing invasion of Ukraine, Europe is investing more in sustainable energy sources that will help the continent build its independence. The declining cost of wind and a growing sensitivity towards environmental issues also help push Europes governments to invest in wind. Germany and the UK are leading the this energy transition shift. Europe now has 236 GW of wind capacity and is expected to install 116 GW of new wind farms until 2026.
Less than half of sub-Saharan Africa has access to electricity, causing a strain on economic growth and social inclusion. Wind energy is quick to install, scale and is a catalyst for large scale foreign investment and industrialisation of the continent. The technology will help reach Sustainable Development Goal 7 and insure everyone have access to affordable and clean energy. Global Wind Energy Councils director of market intelligence Karin Ohlenforst believes that Wind energy offers the opportunity of a scalable, cost-competitive and sustainable source of energy to increase electricity capacity while providing new local jobs and investments.
The Union Of Wind And Sun In Wind And Photovoltaic Energy
Seeing the wind and the sun working together is already a reality in renewables. This hybridisation between wind and photovoltaic energy consists of covering the tower of a wind turbine with flexible organic panels. The energy that it generates makes this system even more sustainable, since it is designed to cover the internal electricity consumption of the wind turbine.
Solar Plants Are Built To Last
Typically when a solar panel is placed, the power agreement you sign lasts between 20 and 25 years. However, the panels dont magically stop working when that date is reached. In most cases, solar panels will be fully functional for twice as long.
Although, by that time, you may want to think about upgrading to newer panels for better efficiency.

Humans have harnessed wind power for thousands of years, using sails to propel ships and windmills to pump water. It has, however, only been in the past 40 years that wind has been viewed as a viable way to generate electricity on a grand scale.
The appeal of deriving power from the wind is obvious: the wind is free, inexhaustible, and always blowing somewhere. The modern wind turbine, pioneered by American and Danish companies following the oil shocks of the 1970s, employed the tried and true angled propeller used by aircraft, to catch the wind, spin, and then use the rotational motion to drive an electric generator. Although other designs exist, the propeller-based Horizontal-Axis Wind Turbine is the one most commonly associated with wind power. Its primacy has been cemented in recent years by its continued technological development.
Use Of Modern Technology
Wind turbines are considered by some to be incredibly attractive. The newest models dont look like the clunky, rustic windmills of old times. Instead, they are white, slick, and modern looking. That way, you dont have to worry about them becoming an eyesore on your land.
The latest advances in technology have transformed preliminary wind turbine designs into extremely efficient energy harvesters. Turbines are available in a wide range of sizes for farms, factories, and large private residences, extending the market with many different types of businesses and by individuals for use at home on larger plots and other plots of land.
Portable wind turbines are also available and can power small devices on the go. The latest models will generate even more electricity, require less maintenance, and run more quietly and safely.

The Wind Energy Industry Creates Jobs
The wind energy industry has boomed since wind turbines became commercially viable. As a result of this, the industry has created jobs all over the world. Jobs now exist for the manufacturing, installation, maintenance of wind turbines, and there are even jobs in wind energy consulting.
According to a report by the International Renewable Energy Agency , the renewable energy industry employed over 10 million people worldwide in 2017. Of these jobs, 1.15 million were in the wind power industry. China leads the way in providing over 500,000 of these jobs. Germany is in second place with around 150,000 jobs, and the United States is a close third with around 100,000 wind energy jobs.
Offshore Wind Resources Are In Deep Waters And Float
The majority of offshore wind resources are in deep waters. This is due to the fact that winds further into the sea are stronger, and there is no visual landscape pollution. The water is so deep that conventional large steel pipe foundations or lattice structures fixed to the seabed are not practical. That is why, many wind projects are developing a variety of different foundations suited to the unique conditions of each site. A number of companies are investing in innovative floating offshore wind platforms. There are multiple types, such as spar-buoy, tension leg platforms, semi-submerse and barge. Around 80% of projects use semi-subversive platforms.

How Do Wind Turbines Work
Wind is created by the unequal heating of the Earth’s surface by the sun. Wind turbines convert the kinetic energy in wind into mechanical power that runs a generator to produce clean electricity. Today’s turbines are versatile modular sources of electricity. Their blades are aerodynamically designed to capture the maximum energy from the wind. The wind turns the blades, which spin a shaft connected to a generator or the generator’s rotor, which makes electricity.
The World’s Largest Wind Farms Are
– Gansu is the largest wind farm in the world, with an expected installed capacity of 20 GW. It has 7,000 wind turbines installed in the provinces of Jiuquan, Inner Mongolia, Hebei, Xinjiang, Jiangsu and Shandong in Gansu, China.
– The largest offshore wind farm is the Walney Extension, in the middle of the Irish Sea, with a capacity of 659 megawatts, enough to provide energy to 590,000 households.

Spaniards Fight With Tomatoes
Well, at least once a year, they do. Every August, one of the worlds wackiest festivals La Tomatina turns the small Valencian town of Buñol into the biggest food fight playground.
The festival is incredibly popular, attracting nearly 40,000 people every year. While the fight lasts only about an hour, more than 150,000 tomatoes are used, turning the streets of Buñol into a scarlet Venice.
The story says that the festivals origin was in 1945 when a street fight broke out between a rowdy local and a group of young people. Next year they repeated the battle , and a tradition was born.
Wind Turbine Pros And Cons
One of the biggest pros of wind power from turbines is that the wind energy generated from a wind turbine is a clean energy source and does not harm the environment at any cost.
It is a great option to be used as a domestic energy source for electricity in different households and commercial locations. But with good things come specific cons as well. The initial cost for installing wind turbines is really quite expensive, especially if you want to connect it with your power lines. Another con that often gets ignored about wind power generated from turbines is that they can negatively harm the wildlife.
If we talk again about the pros, wind turbine energy is sustainable, cost-effective, free fuel, and has low operating costs. All these pros also help in contributing to local and rural communities. As it works with the supply of wind, there is no expense of fuel cost. However, all these wind turbines are only available in remote areas as they are a bit noisy. In fact, many people do not like the way they look, and thus they do not choose to install wind turbines in their wind farms.

We Can Never Run Out Of Solar Energy
Unlike fossil fuels, we can never run out of solar energy. In fact, it is largely thanks to the oil crisis of 1970 that many governments put resources into researching renewable energy sources. That is until our sun fizzles out. But when that happens, humanity will no longer be able to live on Earth. So its really not a problem.
Private Wind Turbines Could Become Popular In The Future
In the United States some homeowners, ranchers and small businesses can have small wind turbines installed on their property to generate wind power for the premises. While this is not common in Australia and not suitable for cities and highly populated areas, its the kind of renewable energy development we could see in the future.

How Turbines Harvest Maximum Energy
If you’ve ever stood beneath a large wind turbine, you’ll know that they areabsolutely gigantic and mounted on incredibly high towers. The longerthe rotor blades, the more energy they can capture from the wind. Thegiant blades multiply the wind’s force likea wheel and axle, so a gentle breeze is often enough to make the blades turn around. Even so, typical wind turbines stand idle about 14 percent of thetime, and most of the time they don’t generate maximum power.This is not a drawback, however, but a deliberate feature of their designthat allows them to work very efficiently in ever-changing winds.Think of it like this. Cars don’t drive around at top speedall the time: a car’s engine and gearbox power the wheels as quickly or slowly as we needto go according to the speed of the traffic. Wind turbines are analogous:like cars, they’re designed to work efficiently at a range of different speeds.
A typical wind turbine nacelle is 85 meters off thegroundthat’s like 50 tall adults standing on one another’s shoulders! There’sa good reason for this. If you’ve ever stood on a hill that’s thetallest point for miles around, you’ll know that wind travelsmuch faster when it’s clear of the buildings, trees, hills, and otherobstructions at ground level. So if you put a turbine’s rotorblades high in the air, they capture considerably more wind energythan they would lower down. And capturing energy is what wind turbinesare all about.

Wind Energy Can Be Used To Power Vehicles
In the course of your research, you must have run across wind-powered vehicles. If you havent, then know that there are vehicles powered chiefly by the wind. A typical example is the widely documented wind-powered car that completed a 3100-mile journey through Australia.
Although it wasnt totally powered by wind, its a perfect example of how vehicles can be moved by alternative sources of energy. Precisely, the car used a combination of batteries, wind, and kite. For the entire journey, the car used an estimated $10 to $15 of energy, which underlines the cost-effective nature of wind energy.
