Mandatory Solar
Interesting energy-related developments from China:
The southern boomtown of Shenzhen has set an example for power-hungry Chinese cities in energy saving by mandating the use of solar power in new housing construction, state media reported.
The law, the first of its kind in China, will require all new residential buildings with fewer than 12 storeys to install solar powered water heating systems, the China Daily reported.
Of course, government-mandated demand wouldn't be my first choice for something to round out the equation, but if governments are going to be madating stuff, I can think of lots worse things than this.
