* Article updated July 28, 2022, with new content and an updated list of green energy startups.

With increasing temperatures, environmental degradation, and ozone depletion, we are all well aware by now that our actions as a species have not contributed to the preservation of this planet and its inhabitants. Perhaps late and lazy, but global leaders - both governmental and corporate - have realized that many things need to change, starting with reducing our carbon footprint. One sector that has made headway in improving the way we “operate” is green energy.

From upcycling used clothes to changing the way we produce food, green tech companies have been trying to “mitigate or reverse the effects of human activity on the environment.” One of the most carbon-heavy sectors in the world is the energy sector, which is why green energy tech companies are at the forefront of the green tech evolution.
