Wind & Solar
This lesson covers:
- How solar and wind power work
- The pros and cons of solar and wind power
power / spin / electricity / generator
Wind is generated by wind turbines which have blades that due to the wind. This spinning action turns a which produces .
|
Wind turbines convert the energy from the wind into e energy.
|
sunlight / power / electricity
Solar is generated by solar cells or solar panels which can generate directly from .
|
The technical name for a solar cell is photovoltaic cell.
Which of the following are places where you're likely to see solar cells?
(Select all that apply)
Roofs
On the front of calculators
Underground sewage tunnels
Large scale solar farms

The pros of solar and wind power are:
(Select all that apply)
They don't produce any pollutants while operating
They don't take up a lot of land area
They have low running costs
They have very stable power production
|
The cons of solar and wind power are:
(Select all that apply)
They are non-renewable sources of power
Their power production is dependent on the weather, and therefore inconsistent
They take up a lot of land space
They have relatively high upfront costs
|
A wind turbine has an average power output of 0.8 MW.
A coal-fired power station has a continuous power output of 1200 MW.
How many wind turbines would be needed to generate the same power output as one coal-fired power station?
