Why is it so hard to compare wind energy to other sources of energy?
Making comparisons between wind and other sources of energy can be difficult because of the cost profiles associated with wind developments. The vast majority of the costs associated with wind developments are upfront capital costs. The operating costs are relatively low but there are maintenance costs including replacement of various components subject to wear, with each additional unit of wind power costing very little to produce. By comparison, conventional gas and coal developments have large capital costs, as well as significant operating costs. Conventional coal and gas fired power stations have more than double the accountable working life compared to wind turbines, and properly maintained could continue to be operated for three times the wind turbine life or longer. The difference in cost profiles creates difficulties when trying to compare the cost of alternative energy sources.
When did Australia start wind farms?

How can Australia produce 40% of its energy?
Greenpeace released a report in 2008 called "Energy [r]evolution: A Sustainable Energy Australia Outlook", detailing how Australia could produce 40% of its energy through renewable energy by 2020 and completely phase out coal-fired power by 2030 without any job losses. David Spratt and Phillip Sutton argue in their book Climate Code Red that Australia (as part of a concerted global effort) needs to reduce its greenhouse gas emissions down to zero as quickly as possible so that carbon dioxide can be drawn down from the atmosphere and greenhouse gas emissions can be reduced to less than 325 ppm CO 2 -e, which they argue is the upper "safe climate" level at which we can continue developing infinitely. They outline a plan of action which would accomplish this.

What is wind power?
In short, wind power is the concept of using the wind to generate energy. Today, that primarily means electricity generation. While the wind is blowing, it spins large wind turbines, which look like massive, modern-day windmills. These wind turbines, in turn, rotate an electricity generator which is then used to power the electricity grid, homes, businesses, and/or communities.
What is wind energy? How do wind turbines work?
The wind has been used as a source of energy for thousands of years. From sailing boats, to windmills crushing grain and creating paper, wind power has always been an important part of human history. While the technology used to generate wind power has changed and evolved over the years, the idea of wind being used in energy generation remains largely the same.
How much electricity does a home use?
A typical home uses just under 11,000kWh of electricity per year. In order for residential wind turbines to be worth it, you would need a wind turbine rated between 5-15kW in order to make any significant contribution to your energy generation and consumption. In addition, many residential properties aren’t suitable for residential wind turbines. If you’re interested in small-scale renewable energy, solar panels are a much more popular choice with many solar rebates available through the government.

How much power does a wind turbine produce?
The figure below shows a power curve for a commercial wind turbine with a rated power of 4000 W. At a wind speed of 4.5 m/s, the turbine only outputs about 230W. At 6.5 m/s this increases to about 900W. At 7.5 m/s, the power output is about 1500W. A massive difference in power output and therefore energy as the height above ground increases.

With this sort of capital outlay it’s important to run some economics.
How Much Energy?
We’ve seen that energy output from a wind turbine is dependent on the power rating of the turbine but also on how strong the wind is and how long it blows. So how can we figure out how much energy to expect out of a turbine? We need this to evaluate the economic performance.
How do wind turbines work?
The biggest factor is the size of the turbine. Wind turbines work by converting the wind that passes through the spinning turbines into energy. They’re about 40-50% efficient at doing this. The spinning turbines define a circle, with wind passing through the area of the circle being converted to energy.
How fast can a wind turbine run?
At the lower end, a minimum wind speed of about 5 m/s is often considered necessary for a wind turbine to be viable. This is 11 mph or 9.7 knots. Commercial wind turbines have different power curves depending on whether they’re designed to operate at lower or higher wind speeds.

Wind speed is obviously critical: the longer the wind blows at higher speeds the more energy the wind turbine produces. So how do we figure out how much wind is at a particular site?
How Do Wind Turbines Produce Energy?
The science behind electricity production from a wind turbine is fairly straightforward. The force of the wind moving over the blades causes them to start moving slowly and then increasing as the wind speed increases.
