The price of sustainability by Kai Neumann

Being tired of the complaints that renewable energy is expensive, that we cannot afford the conservation of natural habitats, that not all people can purchase organic products, that our industry looses jobs, our citizens cannot bear the burden of the costs of sustainable solutions, and so forth I started this model.

But see my arguments in the model and tell us what you would change or even better make the changes directly in the model via the collaborative link.

Now there is little alternative to bargaining a change other than they could decide to change nothing but to get ministries or than to repeat th...
