Top 10 biggest renewable energy companies in the world

Technology Magazine explores which companies are leading the charge towards a sustainable future, as the world's governments tackle climate change

Back in 2020, President Biden laid out a USD$2 tn plan to battle climate change, which placed the U.S. on an "irreversible path" towards net-zero carbon emissions by 2050. As part of this plan, the Biden administration's Build Back Better plan included tax benefits for investments in the renewable energy sector. The global renewable energy sector is expected to rise to USD$1.97 trillion by 2030.

Green energy is generated from renewable resources such as wind, water and sunlight, and investments in the sector have skyrocketed. 

According to a report by International Energy Agency, renewables were the only energy source that saw an increase in demand in 2020 despite the Covid-19 pandemic. BloombergNEF reported that global investment in the energy sector was a record USD$755 billion in 2021, with the renewable energy division of wind, solar, and other renewables making up the most part.
