Energy of Dance: How Much Energy Does a Ballroom Dance Use?

Whether you are like Bambi on ice or exert the grace and sophistication of  Strictly’s Bruno Tonioli, everyone knows how hard dancing can be. The dance floor is an exercise in disguise, and it forces everyone to sweat, burn calories, and use a lot of energy.

We wanted to know exactly how much energy every ballroom dance would use, so we decided to uncover the energy of dance in the most popular styles!

How did we work out the energy usage?

A lot of research, mathematics and dancing went into this equation, but it was mainly split into two factors; human energy and electrical energy.

Human energy

For the banana rating, we used the energy consumption of a healthy individual with average fitness levels. At a more vigorous pace as is seen in dance, you can expect to burn 450 calories an hour, based on an individual weighing 155 pounds. There are 105 calories in a banana, and this was used as a basis for calorie consumption, against the dances and their respective energy requirements.

Electrical energy

In terms of energy, we discovered that a large studio for Strictly-esque dancing would be approximately 15,770 square foot, therefore the lighting would need to be good enough to cover this entire area. We worked out that you’d need 70,3326 lumens to light an entire studio that size. To compare, the sun gives off 10,000 lumens per square foot, so this studio is going to need a lot of bulbs.

The cost of the bulbs

We took the average energy efficient bulb and these typically give off around 800 lumens each, so to light this studio you would need around 880 energy efficient light bulbs.

Let’s say the bulbs weren’t energy efficient, as many people still are making the move to the more efficient versions, this would require around 3517 light bulbs, as they only emit around 200 lumens.

Presuming the studio are using energy efficient light bulbs, we took their expense as 0.5p per hour, due to the bulbs needing one unit of electricity per 40 hours of light. The studio would, therefore, require £44 to be lit up for an hour – quite the monthly bill!

But it doesn’t stop there. We also considered the projectors for all the fancy lighting and washing colours.

The cost of the projectors

The projectors take around 60,000 lumens, around 75 energy efficient bulbs at once. This would amount to a steep £37.50 for the projectors alone, add this together you are looking at £81.50 in lighting per 60-minute episode. Let’s hope they remember to turn them off!

If the average dance length is 2-3 minutes long, the energy efficient lighting cost is just £4.08 on average per dance. Less than a fiver per dance.

That’s how we did it, what do you think of our calculations? We can work out your energy costs, but we will definitely leave the dancing to the experts.
