Answer

In Denmark, the percentage of renewable energy used in 2014 can be calculated as follows:

From the data provided, the renewable energy percentage is 31%. Hence, the answer is 31%.

Step 2

Name the four countries that used a lower percentage of renewable energy than Ireland.

99%

104 rated

Answer

Ireland has a renewable energy percentage of 6%. The countries that used a lower percentage are:

Bulgaria (8%)
Luxembourg (4%)
Malta (3%)
Netherlands (4%)

Step 3

Name a country which did not use gas as a fuel source.

Answer

To calculate the angles for each energy type, we use the formula:

ext{Angle} = rac{	ext{Percentage}}{100} 	imes 360°

Calculating each:

Renewable: $6 ightarrow 22°$
Oil: $42 ightarrow rac{42}{100} imes 360° = 151.2° ext{ (rounded to 151°)}$
Solid Fuel: $13 ightarrow rac{13}{100} imes 360° = 46.8° ext{ (rounded to 47°)}$
Gas: $24 ightarrow rac{24}{100} imes 360° = 86.4° ext{ (rounded to 86°)}$
Electricity: $15 ightarrow rac{15}{100} imes 360° = 54°$

The completed table is:

Type Percentage Angle Renewable 6 22° Oil 42 151° Solid Fuel 13 47° Gas 24 86° Electricity 15 54°

Step 5

Answer

To complete the pie chart, represent each energy type with the calculated angles:

Renewable - 22°
Oil - 151°
Solid Fuel - 47°
Gas - 86°
Electricity - 54°

Label each section clearly to reflect the energy sources used in Ireland.
