This podcast explores the distinction between energy and electricity, emphasizing that energy encompasses different forms while electricity is a specific type. It also discusses the various sectors that consume energy, strategies to reduce CO2 emissions, and the concept of generating electricity without CO2 emissions.
Energy and electricity are often used interchangeably, but energy is a broader term that encompasses various forms, while electricity specifically refers to one form of energy.
Electricity production accounts for only about 40% of the energy used in the US, with the remaining 60% being used for other purposes such as heating, manufacturing, and transportation.

The Difference Between Energy and Electricity
In everyday language, energy and electricity are often used interchangeably, but there is an important distinction between the two. Energy is a broad term that encompasses various forms, while electricity specifically refers to one form of energy. For example, a fire can be considered energy, and its flames can be used to warm a room or cook food. Moreover, by boiling water and creating steam, the heat from the flames can generate electricity. It is vital to understand this difference when discussing energy solutions.
Energy Usage in the United States
Electricity production accounts for only about 40% of the energy used in the United States. The remaining 60% is used for other purposes such as heating homes, buildings, and water. Because heat cannot easily be transferred over long distances, oil or natural gas are often piped into buildings and burned on-site for this purpose. Industries and manufacturing plants also consume significant energy in the production of various products, such as paper, steel, plastics, and chemicals. Additionally, approximately 30% of the energy used in the US is dedicated to transportation, primarily fueling cars, trucks, planes, and ships with oil-based products. Electrifying heat and transportation are strategies to reduce CO2 emissions associated with these energy sources.

Understanding the Distinction Between Energy and Electricity
In this mini-episode of TILclimate (Today I Learned: Climate), host Laur Hesse Fisher breaks down what we’re actually talking about when we use the word “energy”. In a few minutes, we cover the difference between energy and electricity, and the big picture strategy for how to reduce CO2 for each.
Season two of TILclimate focuses on our global energy system, its relationship to climate change, and what our options are for keeping the lights on while creating a clean energy future. We’re partnering with the MIT Energy Initiative, which will air longer interviews to take a deeper dive into these topics.
