According to the U.S. Energy Information Administration, “Renewable energy is energy from sources that are naturally replenishing but flow-limited; renewable resources are virtually inexhaustible in duration but limited in the amount of energy that is available per unit of time.”
To put it more simply, it is energy that is depleted after being used.
On the other hand, nonrenewable energy sources are considered “dirty.” This includes oil, gas, and coal. They are limited in availability and take a long time to replenish.

The main types of renewable sources that we here at Isotherm specialize in include:
- Biomass
