What do you know about Renewable and Non-Renewable energy?

What is a megawatt

Cowessess First Nation

• The Cowessess First Nation and the Saskatchewan government partnered to develop a wind energy project on land southeast of Regina.

Renewable vs Non-Renewable

• A renewable resource is one that can be reused or replaced--like energy from the Sun and wind.

• A non-renewable resource is one that cannot be replaced once it is used up--like coal and oil.

When you turn on the light in your bedroom, you are using electrical energy that was generated far away from your home. A large or smaller scale hydroelectric dam or a coal burning generating plant is probably the source of your electrical energy. 

Up to this point, we have looked at small circuits... how were they powered?

but what if needed to power a whole town?

Generating Electrical Energy

• In 1831, English chemist and physicist Michael Faraday introduced a way to generate a steady supply of large amounts of electrical energy.

• He demonstrated that an electric current can be generated by moving a conducting wire through a magnetic field, a process called electromagnetic induction.

How do we take what Michael Faraday found out and apply it to power our homes and cities?

Mechanical energy --> spines turbine --> spines shaft --> spines generator --> create current

The Grid

• The electrical energy is delivered to a transmission substation where a transformer boosts the generator's voltage for long-distance transmission. The electrical energy is sent through transmission lines to reach cities and towns. The web of interconnections between generating stations, substations, and users is called an energy grid

• Household voltage is typically 120 or 240 volts. For energy to be useful the extremely high transmission voltage needs to be stepped down again. Transformers step transmission voltages, which may be in the hundreds of thousands of volts, down to distribution voltages, which may be less than 10 000 volts.
