Make a contract with a solar or wind farm
The future is all about renewable energy, but to install solar panels for your property can be expensive or some times not practically possible. In Brazil, as in many other countries in the world, it has been a big increase in companies developing renewable energy sources. Farms that harness energy from the sun or wind are distributing clean energy to households and businesses a like in urban areas. Some hostels we have visited in Brasil are in the process of making partnerships with surrounding farms that offer renewable energy without them needing to invest in a lot of infrastructure.
These companies often offer fixed monthly fees which can be a stability in your economy as unusual hot summers, or cold winters, can effect the energy consumption remarkably. Make some research and see if you have providers close to your operation. This is an easy and cost effective way of becoming 100% renewable in your energy consumption!
