A mudança climática é uma realidade que se impõe. A cada ano nosso planeta fica mais quente e os eventos climáticos mais extremos. 15% da emissão global de CO₂ vem de veículos rodoviários. São 5,9 bilhões de toneladas de CO₂ todos os anos. Apesar disso, apenas 1% das motos vendidas na América Latina são elétricas. A eletrificação das motos da região é fundamental para o seu desenvolvimento sustentável. Além da redução de emissões, atinge-se também menor poluição sonora e maior economia por km rodado. Em países como o Brasil, cuja eletricidade vem quase toda de fontes renováveis (85%), a eletrificação das frotas se faz ainda mais importante para reduzir emissões. Mas essa oportunidade é hoje limitada pelos altos custos e baixa autonomia das baterias. Remover esses obstáculos é o que nos move na Vammo. -------------------------- Acreditamos que uma rede de baterias trocáveis e compartilhadas é a solução para esse problema. Ao alugar as motos e baterias a preços menores do que pagariam por uma moto a gasolina, facilitamos a sua adoção, garantindo aos usuários maior flexibilidade e dinheiro no bolso. Ao manter baterias carregadas sempre disponíveis e próximas, oferecemos autonomia praticamente ilimitada, eliminando uma barreira que hoje exclui tantos trabalhadores.

By partnering with over 50 companies Complete Solar continues to diversify its business and is experiencing fantastic growth. Complete Solar began its HelioPro Alliance Program in January 2016 by making its innovative technology platform available to companies looking to deliver lower-cost rooftop systems and more personalized customer service to homeowners.
