Clean water and renewable energy can be a reality for millions of people who still live without.

Clean, accessible water for all is an essential part of the world we want to live in and there is sufficient fresh water on the planet to achieve this. 

Due to bad economics or poor infrastructure, more than 2 billion people are living with the risk of reduced access to freshwater resources and millions of people including children die every year from diseases associated with inadequate water supply, sanitation and hygiene.

Energy is central to nearly every major challenge and opportunity the world faces today. Be it for jobs, security, climate change, food production or increasing incomes, access to energy is essential for all.

The universal access to energy, increased energy efficiency and the increased use of renewable energy is crucial to creating more sustainable and inclusive communities and resilience to environmental issues like climate change.

Bluegrowth is committed to these challenges and in partnership with OffGridBox has the solution to provide clean water and electricity everywhere.

Off Grid Box it is the world's most powerful modular and compact unit that provides renewable energy and clean water for 300 families in remote areas and developing countries.

The photovoltaic roof directs rainwater with a gutter in the 1.500 liters lower cistern. A high-efficiency pump with mechanical and UV (Ultra-Violet) filters sterilizes the water to be used at home, for animals or in the garden. It is possible to add a timer for irrigation, additional water tanks and/or dilute the well water if it is too hard or polluted.

The OffGridBox allows to produce, through the sunlight, up to 20 kWp, store it safely in robust batteries and convert it to alternating current. The solar thermal patented system heats up the water and is integrated with pellet boilers (or pellet/wood) to heat up the whole building.

The patented system integrates photovoltaic and wind energy production, rainwater capture for domestic use and family agriculture, sewage sanitation with solar thermal energy, pellet stove for heating and many other optional parts.
