Power Generation for Wroclaw DT project by Malena, grade 7

Technologies options Wind power Coal power Hydro power

Electricity generation All technologies need a generator that turns. A rotating generator creates electrical power (voltage, current) The difference between the technologies is how to make the generator turn. Electricity is sent around the country using high- voltage power lines. Nearly all of the power we use comes from large power stations.

Wind power Wind power plants use the wind. Wind blows into the blades (turbine) that start to rotate and turn the generator. Advantages: No pollution and very safe No cost for any fuel. The wind is for free. Rather easy and quick to install and take away Renewable energy Disadvantages: Not so powerful, many mills are needed Rather costly to build per power generated The wind does not blow all the time Noisy and some people find the mills ugly Must be built where it is windy

Coal power Coal powder is burned in high temperature to produce very hot water steam. This steam is put on the blades in a turbine that drives the generator to turn. Advantages Coal is cheap and is not scarce. A lot in Poland Powerful, cheap produced electricity Can be built almost anywhere Disadvantages Pollution Global warming, not renewable energy Expensive to take away turbine

Hydro power Water in a dam is let out through a hole deep under water. Then the pressure is strong enough to make the water turn the blades in a turbine that drives the generator to turn. Advantages Water is free Very powerful, cheap produced electricity No pollution Renewable energy Disadvantages Have to build it at waterfalls. Can be far from cities Bad for animals and fish after the dam Expensive and long time to build Expensive to take away If the dam brakes it will be a very big problem

Wroclaw needs Power plant: 270 MW Energy use: 2,4 TWh Available money: 1379 million zl Company that can build How fast is it needed?

Compare Coal Wind Hydro Pollution: A lot No Time to build: 3 years Less than 1 year Cost to build: 650000000$ 2275000000 Zl 22000$ 77000 Zl per mill 30000000$ 105000000 Zl Power output 500 MW 1.8 MW 102 MW Cost to produce: 0.25 groszy 0.320222 Zl 0.335974 Zl Powerful: Yes Many are needed VERY Near Wroclaw: So so Risk: NO One

Chosen Wind And Hydro Because coal makes a lot of pollution and that is bad. For Wind the fuel is free and so for Hydro. Wind is also cheap and does not take a long time to build but the wind does not blow all the time. Hydro lasts for a long time and is very powerful but takes 3 years to build.
