According to the U.S. Energy Information Administration, fossil fuels like petroleum and natural gas still constitute the largest share of energy consumption in many nations, underpinning modern convenience. Understanding what are the sources of energy in our daily life goes beyond the electric socket, revealing a complex web of resources that power our existence.

According to physics, voltage is not a physical substance composed of ingredients, but is instead a measure of the electric potential difference between two points. The concept of 'ingredients' stems from a common misconception, as voltage is an energetic state, not a material object.

Globally, non-renewable energy sources still supply the majority of the energy we use. Our everyday reliance on electricity, a secondary energy source, is fundamentally dependent on these and other primary sources, which are converted to deliver power seamlessly to homes and industries.

According to the U.S. Energy Information Administration, electricity is a secondary energy source, and it is undoubtedly the most widely used in the modern world. Unlike primary sources found directly in nature, such as coal or wind, secondary sources are manufactured from these original inputs. This transformation makes electricity incredibly versatile, powering everything from our homes to industrial machines and global communication systems.

Residential uses of energy account for nearly 40% of total global energy use. Every day, countless actions and conveniences depend on this power. Understanding what four daily tasks require energy sheds light on how deeply ingrained energy consumption is in our modern lives.

Over 300 million tonnes of potatoes are produced globally each year, but can this common vegetable power our lives? While the classic school science experiment shows a potato powering a small clock, the answer to 'can potatoes create energy?' is more complex than it appears.
