Greening Britain One Old Home At A Time

In an era when movie stars build $5 million eco-mansions, families in England have made their old Victorian houses eco-friendly, too. The British government is debating a plan to put some version of smart metering on all 46 million gas and electricity meters in the country’s homes; but most have done it through inexpensive and nearly invisible interventions, like under-roof insulation, solar water heaters and hallway meters, that leave their homes still looking like old Victorian houses.
