Creating a net-zero energy city faces many challenges but technology and design aren't one of them. I've spent countless years researching and at times even living in places that were off the grid and self sufficient. With a combination of good architecture, planning, and teamwork it can be done. The major impediments to creating a truly green city are: political will, money, and belief.
While the idea of a net-zero energy city is growing the amount of money it would take to make this happen is huge. But not as large as most people might think. To make a GreenEarthCity (GEC) from scratch can happen in two ways. First, one group or company in total control building every aspect of the city from the ground up through contracting etc. Second, A group or company developing the blueprint or template and inviting various outside entities to take part in the creation of the city thereby receiving a share of the city. Obviously, there are many ways to economically set up 'ownership' and 'shares' which will be hammered out at some point.
Money: Our country...the U.S.A. has a lot more money to spend then you think. Most of that available money is tied up in Corporate profit and the richest of the rich. But while this might be the case it doesn't mean that these individuals and entities can't take part in the creation of a vision for our future. Those with money can help facilitate the creation of positive change! Money can also be generated by all other socio economic classes of people...if a million people give ten dollars...boom..there's the money to buy the land... and so forth. Our vision of GEC is not about perpetuating the same old economic patterns through. It's about creating an alternative that is democratic in financial vision.
Those alternatives are free to be discussed on here.
Belief: To make something possible you first see in your mind and you believe it can happen. Without that belief and faith to create projects like this will not happen. Let's get together and make a net-zero city happen!
