PARTICLE 101: WIND ENERGY

1 month ago

Anyone opinionated extracurricular connected a gusty time has knowledgeable nan powerfulness of wind.

The spot of this earthy activity of aerial has been harnessed arsenic an power root successful agriculture for more than a 1000 years.

But nan upwind power generated coming is utilized for overmuch much than moving h2o aliases grinding grain.

EASY, BREEZY ENERGY

Wind power is steadily becoming a reliable root of powerfulness for Australian cities and towns.

It’s created by harnessing gusts and gales utilizing wind turbines. When nan upwind blows, it turns elephantine blades – akin to an airplane propeller – astatine nan apical of nan turbine.

The rotation of nan blades spins an electrical generator, producing energy that is fed into nan powerfulness grid.

Modern commercialized upwind turbines are akin to nan accepted windmills utilized successful farming, but they are significantly larger. These turbines tin guidelines up to 150 metres tall, and each leaf tin span up to 90 metres long.

Placing dozens of these immense machines successful a windy location – besides known arsenic a upwind workplace – tin nutrient capable power to powerfulness full cities.

HARVESTING THE WIND

In WA, nan location metropolis of Albany benefits from renewable power produced by a upwind farm.

On nan outskirts of town, 18 turbines look nan Southern Ocean, wherever upwind gusts tin scope much than 60km per hour.

The powerful water breeze enables nan upwind workplace to make much than 35 megawatts of electricity, adjacent to 80% of Albany’s yearly powerfulness needs.

The Albany upwind workplace is 1 of 20 presently operating crossed WA, pinch hundreds of turbines scattered crossed Australia and plans to bring much online successful coming years.

WINDING UP FOR A CLEAN FUTURE

In WA alone, location are more than 30 upwind projects successful nan pipeline to thief present renewable power to nan state.

Wind powerfulness presently makes up 35% of full generated renewable energy successful Australia, 2nd only to star power.

As caller upwind farms are developed, this fig is expected to turn to 50% by 2030, which will thief nan federation arsenic it intends to trim emissions and scope net-zero targets.
