The SQL query to display the average total_units of electricity consumption from the electricity_reading table with an alias name 'average_units_of_electricity' would be:

```sql
SELECT AVG(total_units) AS average_units_of_electricity
FROM electricity_reading;
```

Here's how this query works:

1. `SELECT AVG(total_units)`: This part of the query calculates the average of the `total_units` column from the `electricity_reading` table. The `AVG()` function is an aggregate function that returns the average value of a numeric column.

2. `AS average_units_of_electricity`: This part of the query assigns an alias name 'average_units_of_electricity' to the result of the `AVG(total_units)` calculation. The `AS` keyword is used to assign an alias or new name to the result.

3. `FROM electricity_reading;`: This part of the query specifies the table from which to retrieve the data, which in this case is the `electricity_reading` table.

After executing this query, you will get the average total_units of electricity consumption from the `electricity_reading` table, and the result will be displayed with the alias name 'average_units_of_electricity'.
