The terrible part of this looming catastrophe is that people have been working on solutions for years and have developed concrete steps to massively reduce our energy use, while stimulating whole new industries and technologies that are more efficient and affordable.

The fact of the matter is that today, stuff-selling mega-corporations have a huge influence on our daily lives.
