Clean Energy 101s

Explaining the fundamentals of energy and the climate, along with the basic technologies and critical policies that are essential to decarbonize the world’s energy systems.

The energy transition is big, complicated, and often challenging to understand. Yet that shouldn’t be a barrier to progress. That’s why RMI is developing a growing library of 101s. Clear explanations of energy essentials — from heat pumps and electric vehicles to green hydrogen —  can help untangle this complexity and show how it all connects.

For more on the energy transition and to set the record straight on misconceptions hindering climate action, see our library of “Reality Check” articles.
