As we face extreme climate change and global warming, new and existing startups emerge in the clean energy sector. Consumer demands for sustainable technology are also increasing. So today let us find out the top climate tech companies and startups helping to mitigate this by producing clean energy and offering environmentally sustainable transport and consumer goods.

Top Climate Tech Companies and Startups

Some of the most prominent pieces of climate technology are overall lowering emissions while enhancing the efficiency of energy usage. 

  • Solar and wind power replace fossil fuels and battery storage allows for the storage of renewable power. 
  • Carbon capture reduces CO2 from the atmosphere; hence, it involves capturing and sequestering the gas. 
  • Smart grids help to manage the supply and consumption of energy in the most efficient manner. 
  • Green energy-powered electric cars replace gas-powered cars.
