The Obama administration unveiled a $4bn (£2.5bn) plan to upgrade public housing for low-income Americans today, as part of an ambitious green job-creation project.
Obama sent the vice-president, Joe Biden, and other senior officials to Denver for a formal announcement of the renovation scheme, which will replace windows, insulation and even light bulbs in ageing and neglected housing stock.
I was also intrigued by this idea for financing green home renovations:
The administration envisages a plan where home owners will arrange to have their homes retrofitted for greater energy efficiency simply by ticking a box on their utility bill, and then have the cost of the renovations factored into their bills.
