Difference Between Sustainable and Renewable
The terms sustainable and renewable are often thrown around in discussions among environmentalists and industry experts. They are often used in the context of some sort of primary energy, often interchangeably. Although there is some overlap between the two because we can argue that many sustainable energy sources are also renewable, both the terms have very different meanings. It’s often said that renewable energy can have a transformative impact on the world, but the question is how sustainable is it? Let’s take a close look at the key differences between the two.
Renewable
Renewable means anything that can be replaced or has an endless supply. Renewable energy is energy that is derived from sources that are able to replenish themselves over time whether it’s power derived from air, water, biomass, solar, nuclear reactions, etc. It is energy derived from natural sources that are naturally replenishing on a human timescale. There are various types of energy sources that are renewable such as wind, solar, geothermal, and biomass. The most popular renewable energy source is solar energy, which is derived from capturing radiant energy from sunlight and converting it into heat, electricity, or hot water. Hydropower is yet another widely used renewable power source which accounts for over 18 percent of the world’s total power generation.
