Smart meters will reportedly undergo a massive change and automatically send suppliers updates every 30 minutes on customers’ power use starting from May, the Telegraph has revealed. In May, energy regulator Ofgem will be given the green light to change the way smart meters work, possibly paving the way for “time of use” tariffs.

Which is more polluting—driving a mile to work or walking that mile? The easy answer is, of course, driving. Cars have tailpipes; people don’t. Far more energy is needed to push a 3,000-pound car along the road than is needed to move a 150- to 250-pound body along a sidewalk. Walking seems like the green thing to do.
But appearances can be deceiving, making easy answers dead wrong. That’s the case here when the calories expended in walking are replaced.
Counting the Ways Energy is Consumed in the Food-Supply Chain
The primary reason that walking to work can be more polluting than driving is that growing crops and raising animals so that they can be consumed and digested by humans involves a food-supply chain that now extends to all corners of the Earth and uses a lot of energy. An unavoidable byproduct of this energy use is greenhouse gas emissions. How can this be?
