Thanks for visiting our website. We are a cleantech community aiming to make electricity available and renewable energy tech affordable. How we do this? Together! By sourcing knowledge and networks. The Minimal Mass community works like a think tank, advisory and network. By sharing our challenges we can overcome any obstacle.


We’d love to hear about your cleantech challenge!


At Minimal Mass we like to share as much as we can on cleantech and renewable energy in particular. Follow the latest on our Twitter channel. We also invite you to share your story on renewable energy with. Leave a comment or send us an email.


Renewable energy technology is taking over the world

With a fast pace more and more renewable energy technologies are being designed and existing technology is rapidly improving. Meaning that prices are dropping massively. This makes the technology affordable for and attractive to more and more people. Minimal Mass was founded to speed up this proces. We want to make renewable energy technology affordable, so more people will have access to renewable electricity.


Demand is rising

With all our electric devices – our mobile phones, computers, air conditioning and heating- the global need for electricity is huge and will only increase in the near future. According to the International Energy Agency globally over 1.2 billion people are without access to electricity, but do have access to mobile phones. Also their demand for electricity will rise in the years to come.


Minimal Mass

With only one small solar powered energy system we are able to harvest the endless energy of the sun for many years. Only a small tech device will generate a huge amount of energy. This is the Einstein-principle of minimal mass. Only a small unit of mass can create a large unit of energy.
