Energy is at the heart of everything we do, and it has always powered progress, but the way we harness energy is undergoing a significant transformation. This energy evolution tells a fascinating tale. From the dark plumes of the industrial era to the bright promise of renewable energy resources, we have stepped into the world of sustainability. A world where life and nature sustain.
The word ‘Green’ paints a picture of freshness, gentle calms of forests, clear skies, and the serenity of our planet. But what does green energy mean, and how is it associated with renewable energy? Let us break it down.
What Does Renewable Energy Actually Mean?
Before we define renewable energy as green energy, let us understand what renewable energy truly represents. It is energy sourced from elements of nature that naturally replenish themselves over time, the shining sun, the moving air, and flowing water.
These natural resources, sunlight, wind, water, geothermal, and biomass, are present in abundance and continually regenerate themselves. Unlike traditional energy resources such as fossil fuels, which take millions of years to replenish and fill our atmosphere with harmful emissions, renewable energy resources offer a sustainable way to power our world.
What is Green Energy? Story Behind It!
Green energy is the energy derived from natural, renewable energy sources that have the least environmental impact. The energy resources that have a significant impact on the environment, if not managed well, are not seen as green.
And why is it named Green? It is obviously not due to the color but because it stands for the growth, renewal, and well-being of our planet.
The Subtle Difference
Renewable energy and green energy are often used interchangeably, but there is a fine distinction. As National Grid points out, while most green energy resources are renewable, not all renewable energy resources fit into the definition of green resources.
So where does the difference lie?
Let’s understand the difference with an example. Solar panels, often installed on the rooftops or large solar farms, convert sunlight into solar power and produce no carbon emissions. As this resource has no negative environmental impact, it is considered a renewable as well as green energy resource.
On the other hand, biomass energy, which is derived from organic matter such as plants or animal waste, is considered renewable because it is sustainable compared to fossil fuels. But it is not seen as a green energy resource due to slight emissions production during the conversion process.
What are the differences between green energy and clean energy?
Clean energy is energy that, when used, creates little or no greenhouse gas emissions.
As with renewable energy, some types of clean energy may not always be considered entirely green.
Here’s an easy way to differentiate between clean energy, green energy, and renewable energy:
Clean energy = clean air
Green energy = no harm to the environment
Renewable energy = sources that replenish naturally, such as the sun and the wind

The transition to green energy is crucial to address severe climate change and build a brighter tomorrow.
