20 Top Renewable (Clean and Green) Energy Companies 2023

Decades of industrialization and of excessive fossil consumption have caused Mother Earth to become increasingly hotter resulting in drastic climate change across the globe.

The effect and potential future effects of global climate change have been identified to include longer periods of drought in some regions, frequent wildfire, stronger and more intense hurricanes, melting of glaciers and sea ice, and a huge rise in sea level leading to disastrous floods.

According to NASA, “the effects of human-caused global warming are happening now, are irreversible on the timescale of people alive today, and will worsen in the decades to come”. And the only way future generations can have a better life on Mother Earth is if today’s generation adopts clean and renewable energy.

“Replacing traditional sources of energy completely with renewable energy is going to be a challenging task. However, by adding renewable energy to the grid and gradually increasing its contribution, we can realistically expect a future that is powered completely by green energy” Tulsi Tanti, Founder of Suzlon Group

Two decades ago it was a rare thing to see solar panels on roofs, but now it’s a common sight; a clear sign of the direction the world is going when it comes to energy production.
