Many are starting to question whether or not renewable energy sources like wind and solar panels can efficiently supply power to households, businesses, and even entire countries, sparking a revolution in the energy sector.

With renewable energy sources like the sun and the wind, Australia boasts among the world’s lowest emissions per unit of electricity produced.

Many Australians are considering switching to renewable energy sources to power their homes and businesses, and it’s simple to become swept up in the excitement around this transition.

But how likely is it that Australia will rely entirely on renewable energy sources like solar and wind?

In this piece, we’ll dive deep into the many factors that go into planning Australia’s switch to 100% renewable power, and we’ll look ahead to 2024 to show you what to expect.

What Exactly Is Wind Energy?

Wind power, which uses the wind to create electricity, is a renewable resource. As an eco-friendly replacement for fossil fuels, it is a clean and renewable energy source with zero emissions of glasshouse gases and no other harmful pollutants.

Wind turbines, which consist of tall towers with rotating blades, are used to harness wind energy. A rotor, to which the blades are attached, spins a generator, resulting in electrical output.

The amount of energy produced by a wind turbine is contingent upon its size and design, the wind’s velocity and direction, and the generator’s efficiency.

For centuries, people have harnessed the power of the wind to do things like pump water and grind grain for agriculture.

But in the last few decades, wind energy has become a major source of electricity for buildings, industries, and governments all over the world.

Today, countries like China, the United States, and Germany are at the forefront of the wind energy industry, making it one of the fastest-growing sources of electricity worldwide.

In 2020, wind energy supplied about 8% of global electricity generation; with rising demand for green power, this percentage is only expected to rise.

Compared to other energy sources, wind power has many benefits, such as its low cost, high availability, and ability to lessen reliance on fossil fuels.

However, it has a few drawbacks, such as its intermittent nature and the need for extensive land areas to set up wind turbines.

Despite these caveats, research and development into wind energy is a promising and rapidly developing field, with the ultimate goal of increasing the efficiency and effectiveness of wind turbines and related technologies.

Methods By Which Australia Has Embraced Wind Power

For decades, Australians have used windmills to pump water from bores and rivers for use on farms.

Wind farms throughout Australia have gotten more advanced due to technological development. The Alternative Energy Council reports that in 2019, the wind will surpass hydro as Australia’s primary source of clean energy, accounting for 35% of Australia’s clean energy and much more than 9% of the country’s total electricity.

Our international parent company, ENGIE, is putting a lot of money into wind energy projects in Australia, specifically two wind farms throughout South Australia, as one of its initiatives to pioneer the move to a carbon-free economy.

To put that into perspective, the 32 turbines of the Willogoleche Wind Turbine have a combined power generation of 119MW, enough to supply electricity to 80,000 families across the state.

With its high wind output by global standards, A Canunda Wind Farm can produce power 34% of the time, enough to power 30,000 houses. A large portion of the carbon neutrality of our new energy plans comes from the Canunda Wind Farm, which provides power to counterbalance Simply Energy’s energy-supply activities.

How Does Wind Power Work?

A renewable energy source, wind power uses the wind’s kinetic energy to create mechanical motion that drives a generator.

Energy from the wind is captured and transformed into mechanical energy, which is then transformed into electrical energy that can be used to power homes, businesses, and other buildings.

Wind power is generated by wind turbines, which look like tall, slender towers with three blades that turn in the wind to create electricity.

A rotor, to which the blades are attached, spins a generator, resulting in electrical output. Multiple variables affect how much energy a wind turbine can produce: blade area, wind velocity and direction, and generator efficiency, to name a few.

When the wind blows, it turns the turbine’s blades, which spins the rotor, which in turn generates electricity. The shaft is coupled to the generator, and the rotor is connected to the shaft. Electricity is generated as the rotor spins the generator.

A transformer is typically used to increase the voltage of the electricity generated by the wind turbine so that it can be transmitted over long distances.

Once the power is transmitted to a substation, it can be distributed to the rest of the electrical grid and ultimately end users’ homes and businesses.

Wind power is advantageous because it is a renewable energy source that doesn’t contribute to global warming or cause pollution.

However, there are also drawbacks to using wind power, such as its intermittent nature and the need for expansive land areas to set up wind turbines.

Wind power, despite these drawbacks, is a rapidly expanding field with constant research and development aimed at increasing the efficiency and effectiveness of wind turbines and related technologies.

Australian Wind Energy

It is one of Australia’s primary renewable energy sources, providing 7.1% of its electricity demand.

Throughout 2018, 94 wind farms contributed roughly 16 GW to Australia’s grid.

Together with utility-scale solar PV, this energy type is one of Australia’s cheapest options for expanding the country’s electricity grid.

Power from new wind farms in Australia is anticipated to cost between $50 and $65 per megawatt-hour (MWh) in 2020, and less than $50 per MWh by 2030 as the price of power wind energy continues to drop.

In what ways are we assisting wind energy initiatives?

Our goal is to help Australian consumers, businesses, and employees profit from the global transition to net-zero emissions by hastening the rate of pre-commercial innovation.

We are contributing to establishing Australia’s renewable energy ecosystem by facilitating the flow of capital, information, and human capital to spur the development of innovative energy technologies.

Australia has long relied on wind power as a reliable source of electricity.

Thus, we have prioritised funding for initiatives that improve the safety and consistency of the power grid, such as those that show how wind farms can stabilise the power grid by providing essential services (PDF 1MB) or work in tandem with solar farms and energy storage to increase grid reliability.

Wind And Solar Power Require Far Less Land Than Coal Power

Coal power, which currently provides 63% of Australia’s electricity, may be replaced with wind and solar generating plus energy storage at the lowest possible cost.

The only chance existing power plants powered by coal can make a profit soon is if corrupt politicians dole out favours to fossil fuel businesses due to the falling cost of renewable energy and battery storage.

Even if the corrupt politicians never see a single dime of corrupt money, it won’t make a difference.

Anyone who accepts tax dollars to subsidise an activity that ultimately costs more lives through increased government spending is morally bankrupt.

But, there are still people in the shadows of the internet and Parliament who insist on rehashing the tired old myths that exist even though we now have access to cheap energy that can power civilisation without destroying it.

Too much land is needed for wind and solar power plants, and
They aren’t cost-effective since they need too much stuff.

A person who says such a thing is an idiot. Idiots, in the contemporary sense of the term, are those who can think but choose not to.

If they’d bothered to think about how much space and resources are needed for just a coal generating station before accessing the internet to check some simple facts, they’d know they were incorrect or at least realise they don’t know what they’re talking about.

Using my photo-stealing skills from Google Maps, We will show how solar and wind power generation requires much less land than coal, putting to rest these two zombie beliefs.

You know, we may not be able to put an end to these shambling monsters, but they seem to be disintegrating, so maybe we can finally put an end to these zombie thoughts once and for all.

Power That Can Be Dispatched

Coal-based generators can be called upon at any time. That signifies it has an on/off switch that can be used as necessary. At least, in theory, that’s the case.

Coal power plants are expensive to start and stop and must generate between 42% and 60% of their rated output at all times.

Renewable energy sources like the sun and the wind are steady but unpredictable. They’re dependable since we can anticipate how much energy they’ll generate using weather forecasts.

In addition, the failure of a single solar inverter and wind turbine has a negligible impact on overall output, in contrast to the shutdown of an entire coal power plant.

Yet, because the output is weather-dependent, it cannot be dispatched, despite its dependability. Turning on a solar farm before midnight is not a viable choice if you require immediate access to electricity.

Using energy storage, renewable sources like solar and wind can be effectively dispatchable. Space-consuming methods like pumped storage exist, but the declining price of batteries has made them increasingly attractive.

This Google Maps aerial view of Australia’s largest utility-scale batteries, the Hornsdale Power Reserve, demonstrates that utility-scale batteries have a small physical footprint:

Solar, Wind, And Batteries Require Significantly Less Land.

Renewable energy sources require significantly less land than coal, as demonstrated by my remarkable command of coloured rectangles.

Nonetheless, coal mines simply remove significantly more area from their actual usage per kilowatt-hour produced than renewables do, even though some Australian coal produce so much coal per sq. km that Leigh Creek did, and many employ secret tunnels instead of an open cut.

More and more energy can be produced with less area devoted to their use as solar panel efficiency rises and wind turbines grow.

Since it will be less expensive to produce more renewable energy than is required and let part of it go to trash than to store it, We anticipate that in the not-too-distant future, we will build extra renewable power to a great extent.

But this is not an issue. To begin with, there are still plenty of places to put solar panels on our rooftops.

Wind Energy’s Advantages And Disadvantages

Pros

As a resource, the wind is readily available, can never be depleted, and costs nothing to harvest.
Wind power is the cheapest form of large-scale renewable energy at present. Thus, it’s not only environmentally friendly but also very cost-effective.
Onshore wind farms can be constructed on land, near existing farms, or offshore, in the ocean (i.e. out in the ocean).
Modern wind turbines have greatly reduced noise pollution. At fifty metres away, they sound like a refrigerator.

However, wind energy also has several disadvantages, including:

Cons

As the amount of energy harvested from the wind varies greatly from day to day and even hour to hour, it is an intermittent energy source.
Installation of wind turbines is difficult in areas where land is scarce or where people live in close proximity to one another.
People who live in close proximity to wind farms may be concerned about the noise pollution that is generated by the turbines.
When wildlife, such as birds and bats, fly too close to wind turbines, they risk being injured or killed in a collision with the blades.

Despite these drawbacks, wind energy is a rapidly expanding field, with research and development aimed at overcoming them and enhancing the efficiency and effectiveness of wind turbines and related technologies.

FAQs About Wind and Solar Power

What are the primary differences between wind and solar power?

Wind power and solar power diverge mostly in the form of energy they harvest. Energy can be harnessed from the wind with wind turbines or from the sun with solar panels.

Which renewable energy source is more efficient, wind or solar power?

Location, wind and sun exposure, and the particular system employed all contribute to the overall effectiveness of wind and solar energy. Depending on the conditions, wind turbines may be able to provide more electricity than solar panels.

What factors should be considered when deciding between wind and solar power?

Where you live, what kind of resources you have access to, how much energy you use, how much it costs to install and maintain, and how much of an impact it has on the environment are all things to think about when choosing between wind and solar power.

How do installation costs and maintenance differ between wind and solar power systems?

Wind and solar energy systems might have varying installation and maintenance costs and needs based on the exact system and area.

Wind turbines, in comparison to solar panels, typically have a greater initial investment and ongoing maintenance costs. Compared to other energy sources, solar panels are less complicated to set up and require almost no upkeep.

Which renewable energy source has a lower environmental impact, wind or solar power?

Compared to conventional fossil fuels, both wind and solar electricity have a smaller impact on the environment.

However, wind turbines can have an impact on the surrounding environment in terms of both visual and audible disturbances, and solar panels need the usage of rare earth minerals that might have harmful effects on the environment during their production.

The overall effects on the environment of using renewable energy sources like wind and solar will vary greatly depending on the particulars of each case.

Conclusion

Using the wind to generate electricity is the basis of wind energy, a renewable energy source. There are no glasshouse gas emissions or other pollutants produced by this renewable energy source.

Wind energy can be captured and converted into electricity by using wind turbines, which are tall towers with rotating blades.

There has been rapid expansion in the use of wind energy as a power source for homes, businesses, and even entire countries. About 8% of the world’s electricity generation in 2020 came from wind power.

Using the kinetic energy of the wind to drive a generator is the basis of wind power, a renewable energy source. Advantages include its low price, abundant supply, and ability to reduce reliance on fossil fuels; disadvantages include its intermittent nature and the need for large tracts of land.

Wind energy is widely used in Australia; 30,000 homes’ worth of electricity come from just two wind farms in South Australia.

Wind turbines, which resemble tall, slender towers with three blades, generate electricity by turning in the wind.

The amount of energy a wind turbine can generate is dependent on a number of factors, including the size of the blades, the speed and direction of the wind, and the efficiency of the generator.

Solar and wind power generation can be activated at any time and require significantly less land than coal. Constant but unreliable, solar and wind power are two examples of renewable energy that aren’t ideal for 24/7 power needs.

Since the price of batteries has been dropping, energy storage methods like pumped storage have become more competitive.

Land use for solar, wind, and batteries is much lower per kilowatt-hour generated than it is for mining coal. As solar panel efficiency improves and wind turbines increase in size, more energy can be generated on a smaller footprint.

More renewable energy infrastructure is planned for construction in the near future. Wind farms can be built on land, near existing farms, or even offshore, making them the most cost-effective form of large-scale renewable energy.

As an added bonus, it has reduced noise pollution, is cost-effective, and is easy on the environment. However, wind-generated electricity must be stored until it is needed.
