RVE.SOL - Solucoes de Energia Rural
Series A in 2020
Rural populations forced reliance on biomass and kerosene for their energy needs is causing over 1.6M# deaths per annum. Their lack of access to clean water causes over 5M people to die; 2M of them are children under the age of 5.
RVE.SOL's _Changing Rural Life Forever_ initiative is creating alternative, renewable energy choices for the rural poor, allowing them to take advantage of natural resources like sunlight, cattle manure and raw water to manage their own way to a better future.
Our _KUDURA_ rural village energy hub is community managed; provides communities with potable water, solar electricity, biogas for cooking and organic fertiliser for agriculture.
A holistic approach, the solution seeks to target the four areas of rural life that prevalently cause poverty to propagate:
1. Access to clean water to obviate transmission of water borne disease
2. Access to renewable electricity to obviate the dependance on kerosene for light and improve children's opportunity to study at night
3. Access to Biogas to obviate mass destruction of primary forest in a bid to be able to cook food
4. Access to fertiliser to reinvigorate over-used soils and so increase quality and quantity of crop harvest for subsistence farmers.
Ultimately, this approach seeks to create wealth for rural farmers by offering a choie of more cost effective and efficient services utilising naturally available resources.
